Rollout or Roll Out – What’s the Difference?

Home » Rollout or Roll Out – What’s the Difference?

Sometimes, people use common phrases so often that they become lumped together into a single word. That’s what happened with skyscraper , woodpecker , and breakup .

New writers often wonder if it wouldn’t be simpler to leave the words separate. There are some instances where to do so would be appropriate, depending out how you use the phrase in a sentence.

Rollout is a great example of this—in some contexts, it should be compounded, and in others, it must be separated into individual words.

What is the Difference Between Rollout and Roll Out?

In this post, I will compare rollout vs. roll out . I will use each of these words in at least one example sentence, so you can see how they appear in their proper context.

Then, I will show you a mnemonic device that makes choosing either rollout or roll out for your own writing a much simpler task.

When to Use Rollout

Oftentimes, a rollout will occur in stages, where the top-tier product is introduced first, followed by lower-tier products after the initial excitement has dissipated.

Here are a few examples of rollout in a sentence,

• When the rollout for Windows 8 was met with widespread derision, Steve Ballmer left Microsoft and bought a basketball team instead.
• The new company organized a swift, orderly rollout of its products to capture the attention of its consumer base.

When to Use Roll Out

• Apple rolls out its new iPhones at its Worldwide Developers Conference.
• I will fine-tune the new procedures at a few test sites before rolling them out companywide.

The standard rules of compounding in English are at play here. When a phrase is used as a noun, it is often compounded into a single word, like rollout . As a verb, the words are more likely to remain separate, like in the verb equivalent roll out .

You can see this with other words like breakdown , buildup , makeup , setup , among others.

Occasionally, if the phrase is used as an adjective, it might be hyphenated, to form something like roll-out .

Roll out could also mean to unroll something , like a sleeping back or a spool of yarn. Sometimes, it means to leave , like in the phrase Let’s roll out .

Trick to Remember the Difference

Roll out vs. Rollout Check: Since roll out is a phrase made from two individual words, and roll itself is a verb, it is easy to remember that roll out is a verb phrase.

Is it roll out or rollout? The two are not interchangeable, so be sure to use the noun when you need a noun and the verb phrase when you need a verb phrase.

• Roll out is a verb phrase that means to introduce something , like a new product line.
• Rollout is a noun that means a product introduction .

Why Does My Flame Rollout Switch Keep Tripping?

Resetting the furnace rollout switch can fill your mind with worries, and for a good reason – it’s usually a sign of a significant underlying problem. Moreover, resetting the switch often feels like you’ve just escaped a major disaster. 

It would be best to try to prevent issues that may cause the rollout switch to trip for the above reasons. And if it trips at some point, the most important thing is not to switch it back ON but to fix the underlying issue. 

Below, we discuss the most common reasons the flame rollout switch may trip, symptoms of a tripped rollout switch, and what you can do it. Let’s begin with a brief overview of flame rollouts and how flame rollout switches work. 

What Causes Flame Rollout?

A flame rollout is when flames roll out of the combustion chamber of your gas furnace. The rollout is typically caused by the interaction between flames and combustion gases in the gas chamber. 

When the furnace is up and running, it sustains a flame that’s meant to provide heating for our home. However, under normal circumstances, the flames are meant to remain within the walls of the combustion chamber. 

Unfortunately, sometimes inflammable gases can build inside the gas chamber, preventing oxygen from getting to the flames below. The buildup of gases is caused mainly by soot buildup. Excessive soot can prevent gaseous byproducts from leaving the combustion chamber. 

As these inflammable gases build up, they cut the oxygen supply to the flame below – which critically needs oxygen to keep burning. 

So, what follows? The flame has to try every means to find the oxygen it needs. Thus, the flame may sometimes roll out of the combustion chamber to reach the oxygen just above the layer of soot outside the combustion chamber. 

Another common cause of flame rollout is a blocked flue pipe. The flue pipe is a small vent that releases combustion gases outside the combustion chamber. When the vent is blocked, combustion gases cannot escape outside the furnace. This often leads to the buildup of incombustible gases within the furnace, eventually leading to flame rollout.  

Flame Rollout Risks

Flames rolling out of the furnace gas chamber is extremely dangerous. For one, it puts your life and the lives of your loved ones at risk. What if the “floating flame” reaches a flammable item and catches fire? It creates massive danger and could potentially burn down the house. 

Moreover, even if the flying flames don’t burn the house, they may reach parts of the furnace not designed to handle the high levels of heat or open flames. This can result in accelerated furnace degradation, leading to expensive repairs or replacements. 

Finally, flame rollouts can also point to serious underlying issues that may put you and your family at risk. For instance, sometimes rollouts happen because of a cracked exchanger. A cracked heat exchanger creates a significant risk for carbon monoxide leaks – a poisonous gas that can cause asphyxiation and even death. 

What’s a Flame Rollout Switch?

The flame rollout switch is a safety mechanism built into furnaces to protect you and the furnace in case of a flame rollout. It shuts down the furnace immediately it detects a flame rollout to prevent potential fires. 

How it works is pretty straightforward. The rollout switch is wired to the circuit of your furnace’s internal power source. Thus, it cuts off power to the furnace when it trips, causing the furnace to shut down. 

The switch is located near your furnace’s burner box. It’s a rounded device with a switch sticking out of the top. You’ll be able to identify it thanks to the two metal strips, about an inch each, attached to each side of the switch. The strips have holes at the tips furthest from the switch. 

Fortunately, you can reset the switch yourself when it goes off. You need to press the center button. However, it’s usually advisable to fix the underlying issue first. 

What Causes Flame Rollout Switch to Trip?

Although it primarily monitors flame rollout and will instantly go off when a rollout is detected, the flame rollout switch can also be tripped for a few more reasons. Here’s what you need to know;

1. The flame has rolled out

This is the primary reason the rollout switch will trip. If it detects flames outside the pre-defined regions of the furnace, it will go off right away to prevent a potential fire. 

As we’ve seen, a flame rollout can happen for many reasons. Perhaps you have a blocked flue that keeps combustion gases within the gas chamber. Or maybe it’s a cracked heat exchanger. Whichever the case, if there’s a flame rollout, the switch will trip. 

2. Overheating 

Sometimes the rollout switch may also trip if overheating is detected in certain parts of the furnace, even if there’s no flame rollout. For instance, if areas beyond the heat exchanger become extremely hot, they may catch fire. The rollout sensors will treat it as a rollout event and trigger the rollout switch. 

Overheating can result from many events. For instance, it may be the result of an undetected flame rollout. Also, it could be a sign of a bad heat exchanger. The heat exchanger’s primary function is to contain the heat within the furnace. Therefore, a bad exchanger may allow excessive heat to reach other parts of the furnace. 

3. You have Low Gas Pressure 

You’re probably wondering how low gas pressure can cause the rollout switch to trip. It’s easy. If you have low gas pressure, the flame retreats from the burner port back into the burner body. Sometimes it may retreat to the burner orifice. 

This is extremely dangerous as overheating the orifice can cause the internal components of the gas to fail. It’s also a lot more challenging to control a flame burning deep inside the orifice.

Above all, it constitutes a flame rollout because the flame would be burning outside the designated zone. Thus, it’s enough reason to trigger the rollout switch. 

Symptoms of a Tripped Rollout Switch

Knowing when the flame rollout switch is tripped isn’t as straightforward as you’d wish. You’ll need to be highly observant. Check out for the following;

• The burner goes off

This is obvious. As we’ve seen, the rollout switch is wired to the furnace circuit board and works by disconnecting power to the board to shut off the furnace. Therefore, the first thing that will happen when the rollout switch is tripped is that the burner will go off. 

• The blower fan keeps running

In addition to the burner going off suddenly, you want to listen out for a humming blower fan. Gas furnaces are programmed such that if overheating or a flame rollout is detected, the blower fan remains ON for a while longer to cool the unit down. Unless you shut off the furnace, the blower fan will keep running until the furnace reaches a pre-determined temperature. 

• The button on the switch is popped

Most rollout switches are “one-time” switches. Once the switch trips, you have to replace them. However, others have a button in the middle that pops up when the switch is tripped. You can pop the button back into position to reengage the switch and reset the furnace for the latter. Just be warned that doing so without addressing the underlying issue can cause even more problems down the line. 

• Control board blinking error code 

This also doesn’t apply to all furnaces. However, some are designed to blink pre-determinedly to alert you that the rollout switch has tripped. The light will blink a specified number of times, depending on the manufacturer. Cross-check with the user manual to verify the issue. 

• The burner won’t stay lit 

It’s natural to try to relight the furnace when it goes out. It will not stay lit if the rollout switch is tripped. Why? Because, as we’ve seen, a tripped rollout switch cuts supply to the board. Thus, you can only resume heating after switching the rollout back ON. This means that the burner will go off within seconds of relighting it until you switch back the rollout switch.

How to Test a Rollout Switch

You can easily test whether your rollout switch is working using a multimeter. Multimeters cost about $30 at the store. 

How to Fix Furnace Flame Rollout Switch

Fixing a flame rollout switch isn’t difficult. However, the exact fix will depend on the type of switch and type of damage. 

If dealing with “pop-up” switches that pop out of the socket when the switch is tripped, you need to pop the top part back to reset the heater. However, if it’s a one-time switch, you need to replace it because it won’t work after tripping. It’s best to find an HVAC pro for the installation. 

Flame rollouts are extremely dangerous. You must never take them for granted. You should take every precaution to prevent gas furnace flame rollouts. However, if it happens, the rollout switch will help keep you and your loved ones safe.

First look at the burner burning with blower off take note of each burner and the tip of the flames. Then with the burner and blower both running has the flame changed. Is any of flame pushing out towards the front of the burner that would be a problem with a crack in the heat exchanger. Other problem is when the burner doesn't light correctly and it starts burning back in the orfice. Did your pull all the burners when checking the heat exchanger and look with a mirror and flashlite in each section.

@fitter30 -- No, there's no change in the any of the four burner flames when the blower comes on. I've finally witnessed the issue. The furnace begins to shutdown -- the burner stops, then in 1-2 minutes the draft fan stops, then in a minute or so the problem happens. You'd expect the blower to stop, but instead the burner starts up without the draft fan running. As you'd expect without the draft blower running, the flames all struggle to stay contained and fill up the burner space, and finally one of the the rollout switches trip. Then the furnace enters the state of having the duct blower run indefinitely, typical to when a rollout switch trips. When this "restart-without-draft-fan" event happens, the draft fan is still coasting to a stop when the burner lights, but is obviously not receiving power. To rectify, I kill the power to furnace, reset the rollout switch, and turn the power back on. Now this doesn't happen reliably. Rather, the furnace can operate fine for a day or a few hours, which is what was making it elude me (I'd get tired of sitting by the furnace waiting for something out of the ordinary happen). 2 weeks ago I disassembled most of the furnace -- removed the gas valve and manifolds, burners, blowers, and inspected the heat exchanger. All looked fine, and after I reassembled it, the furnace worked fine for about 10 days. Prior to that I also swapped the main controller board between my two furnaces (my other is the same make/model/year and uses the same board), and the problem stays with this furnace. What would cause the furnace to shutdown, and then startup again without the draft fan running? (it's a new draft fan, installed in October at the beginning of the season -- the old one had seized up). Could it be the overheat switch? I replaced the filter in October, and we don't have particularly dusty habits; the old filter looked not-too-dirty. I believe that furnace frequently cycles off and then immediately on again, mostly without the rollout occurring, when the thermostat is still calling for heat. This seems odd to me.  

Can't find any info on furnace what brand and number of the burner module  

• Jan 3, 2021

The model number is GNE100J20A1 -- ICP/International Comfort Products, with a label "ComfortMaker RPJ-II" on the cover. I took out the filter, and now it's stopped rolling out. I waited to reply back until I was sure, and it's been 36 hours and no roll out. I guess the filter was restricting flow and causing short cycling. My guess is that the high temp switch is opening, the burner goes off and a short time after the draft inducer fan, and then before the blower stops the high-temp switch closes; since the thermostat is still calling for heat the burner starts up again. But somehow the logic in the board doesn't start the draft inducer. Is this typical -- after the trip circuit opens and re-closes, the control board allows burner startup from non-initial off state? Hmmm... I'll reinstall the filter, connect up a meter to the high-temp switch, and sit-n-wait for the roll out to be sure it's the trip circuit opening and the high-temp switch doing it. If this is what really happening then I may have duct-work problems (besides the controller behavior). The filter I'm using is FPR12 and by its appearance looks much more restrictive than a cheaper filter (DP complained about smells from the ducts so I got this one). So it's back to cheaper filters for me. The home is mainly a single story, so all ducts are on the basement ceiling and accessible. The ducts are a combo of fiberboard and flexible. The flex is held up by straps, and some of them sag. Seems to me that this causes some restriction. Perhaps over the years this has been getting worse, and my choosing an FPR12 was the tipping point. So today I'll pickup some lighter filters and straighten out some ducts to see if I can get it stable again. If anyone has further suggestions then please share.  

Need to inspect the blower cups on the wheel for dirt. If the wheel is caked ac coil might be dirty also.  

• Jan 4, 2021

I switched back to lightweight filters and the short cycling stopped. FPR 4 (HD, dunno what the MERV rating is) - these are 1" thick (25" x 16"). The slot is cut from the fiberboard that's glued to the side of the furnace with mastic. Perhaps I'll see if I can widen the slot to take thicker filters.

Hi @Chevsky , I hope you are well, I just came across this thread and I am facing the same issue with my furnace. My switch keeps tripping if the heater is running for more than 12 minutes. So I set the heat to 19.5C so that the burners are not on for more than 10 minutes and it is running fine. Please advise how did you fix your problem or any insights on to what's going on with my furnace ?

What is Furnace Flame Rollout and How Can You Prevent It from Happening in Your Home?

When your furnace is well-maintained and working properly, it doesn’t pose any safety risks to your home. However, if your furnace is poorly maintained, experiencing operational problems, or reaching the end of its operating life, it can encounter some safety issues that can be of serious concern. One such safety hazard is a flame rollout. Today we’re going to talk about what a furnace flame rollout is, the dangers it causes, and what you can do to protect your system from a flame rollout!

What is a furnace flame rollout?

When your furnace is turned on, its burners emit steady flames that are supposed to be confined inside of your system’s combustion chamber. Under certain conditions, inflammable combustion gases can build up inside the combustion chamber and starve the flames of oxygen. When this happens, the flames grow larger and larger in an attempt to receive oxygen, eventually causing the flames to “roll out” of the confines of the combustion chamber.

You can detect a furnace flame rollout if you notice any signs of singing or discoloration on the exterior of your furnace’s combustion chamber or other nearby parts. You might also be able to see the rollout occurring if you inspect your system at the right moment.

What causes a furnace flame rollout?

As we mentioned above, flame rollouts occur when inflammable combustion gases build up inside of the combustion chamber. This can happen for several reasons:

• Soot buildup prevents combustion gases from exiting the combustion chamber.
• The flue pipe is blocked somewhere, preventing combustion gases from being vented outside.
• The heat exchanger is cracked.

Why are furnace flame rollouts so dangerous?

When flames are rolling out of your furnace’s combustion chamber, they will heat the temperature around parts of your furnace that are not designed to handle such high temperatures. This will not only damage some of your furnace’s components, but also possibly cause something nearby to catch fire.

In addition, a furnace flame rollout might be an indication that your heat the exchanger is cracked, which would suggest that carbon monoxide is getting into your home’s air.

How can you protect your furnace from a flame rollout?

Your furnace has a safety device that is designed to detect flame rollouts. It’s called a flame rollout switch, and it cuts off the gas supply to your furnace when it detects higher temperatures than normal immediately outside the combustion chamber. The best way to ensure that this device is working properly, and to prevent flame rollout in the first place, is to schedule a tune-up every year so that we can look for signs of rollout and take care of issues before your system becomes a safety hazard.
