Furnace Flame Roll Out Switch Tripped - How it Works

Is the flame roll out switch tripped in your furnace? In this video I explain what the flame roll out is, why it trips, and what you would need to do next. Unfortunately in most cases a tripped roll out switch is a bearer of bad news but once in a while it can be a bad switch or something wrong with the exhaust venting.

Best video! A guy came out and said I needed a whole new furnace… the roll out switch tripping was intermittent, so I knew it was a blockage somewhere. Went to the pipe on the roof clogged like cement with debris. Fixed furnace perfectly! Saved me 7 k

[leemuller]

I removed air filter just to test and it still got tripped. Blower motor still going, so not water in blower. Found my condensation line plugged from dirt in the utility sink. Cleaned that out, and now seems to be running fine. Thank you for posting the video. Saved me $$$!

Thank you for this video. Furnace was off since last night and it's 19 degrees with whipping wind. My minutes knowledge of furnaces reminded me that there are error codes. Got my six blinking red and google brought me straight to you. Was able to reset the switch and now I can brag for the rest of the week. Lol

I woke up at 4:00 am to the furnace blowing cold air. It took me 5 minutes to fix the problem after finding your video. Thank you so much!

My furnace flame roll out switch tripped late Saturday night. No heat most of the night. Spend some time trying to figure out why nest stop working. Short story after couple of hours of good cold sleep, I end up finding this video early morning. Thanks to you it was a flame roll out switch tripped. I reset it and burner kicks in with nice cone shape flame as described in this video. I have a call out to furnace company to come out. At least house is started to warm until the technician comes later today. Thank you again and very helpful content.

Another thank you for all your great vids. After watching a few I was able to diagnose the issue I was having. The furnace shut down after running for about 5 minutes and only the inducer motor was coming on after I would restart it. My particular model has two of these switches. One in the flame box and one next to the inducer. I found the one at the inducer had tripped so I reset it and ran the system again. I noticed the exhaust duct was getting hotter than normal much faster than it should and tripped the switch again. I went through your diagnostic tips and found I had a broken vent on my roof. The rain cap was siting directly on top of the pipe blocking just enough flow to cause the problem. I made a temp fix to hold the vent cap in place and it's working as it should again. So, a prime tip for all you homeowners that have a roof replacement done during the summer, get up there an thoroughly inspect all your vents when the job is done. If I had noticed it then I could have had the roofing company install a new one on the spot instead of having to do it myself.

Thanks, this video helped me solve my problem. Our thermostat was rebooting, but only during heating cycles. I couldn’t determine why and figured it must be a faulty thermostat. As it turns out, that was not the case. I ended up having a 33 code for an open flame roll out switch. Well, that would explain the resetting thermostat because the furnace was essentially shutting down and resetting itself…thus no power to the thermostat and the reboots. But, the problem was not actually flame roll out at all. There was no evidence of flame roll out, flame cones were fine, nothing blocked, filter is four weeks old, furnace is seven years and only 58, 000 BTU. Turns out…it was the filter, but not because it was dirty…it was because it was too restrictive for air flow. The furnace would come on and there was not enough air flow to pull the heat from the heat exchanger fast enough resulting in the furnace heating up internally and tripping the roll out switch. The filter simply could not pass enough CFM. Took out the filter, problem solved. The filter was rated at MERV 11. I put in a new filter rated at MERV 8 and no more roll out switch tripping…and consequential potential damage to our furnace. High MERV may be good for air filtration…but not necessarily for your furnace.

Jay's videos are the go to place on YouTube when you have a furnace problem. THANKS BIG MAN. Sorted it again!

[AJJ]

I'm updating from my original post as my issue has been resolved and I credit your video for educating me. My heat (13 years old) would come on and then switch off and it turned out it was a lack of maintenance on my part. The technician cleaned the sensor and cleaned out the condensation line and it's worked perfectly ever since. I told the repair company what I thought it may be based on this video which cut down a lot of trouble shooting on their end and possibly saved me a lot of money because they could've very easily said I just need a new system. Thank you!!

[ytocam]

This video just saved me alot of stress I’m a DIYER so I feels good to learn things and know how to fix them

[dw]

You are the only one who I found that solved my problem I have made 5 trips to the hardware store 3 to Walmart switched out my thermostat twice they sold me the wrong one I finally got it wired back up then exactly like you showed my error code flashed 6 times and now after watching this video I can go home tonight even though it's 30 degrees I can hopefully have it up and running by tomorrow thanks for your video I rent so instead of my landlord taking his time getting someone out there to fix it I'll do it myself and learn what to troubleshoot by your channel thanks 👍

[chelseamartini]

This video quite literally saved our house last night. -55 in Montana last night 🥶 thank you!!

[hiphopwong]

Thank you for this video, I paid way too much for a new ignitor, and pressure switches and it was the flame roll out switch tripped!

[cesar]

Good explanation and breakdown of the symptoms this was my issue. House was at 53 degree and 30 degrees outside.

[unclefrank]

Thank you so much. Had a blockage in the burner assembly right after the gas jets. Cleared it out no no more problem and the furnace is running better then when I moved in.

[pecan]

Well a first for me! My roll out switch tripped and after a lot of trying, I realized that when I separated the flue that goes to the roof to clean it of some refuse, I didn’t get it back on exactly right. I had just replaced the flame sensor and cleaned the flue and then when trying to start furnace it kept interrupting the ignition cycle. Long story but the pressure switch code was on and I realized the induced draft was slightly pulling thru the inside of the cabinet and causing a slight temp increase which was shutting down the roll out switch. We took the flue off and replaced it back in and voila! The furnace works great now! Wow I learned something really valuable here

[chairde]

I like that you explain details in a calm pace. Not too fast, not too slow.

[jamescourier]

Fixed my furnace in like 10 seconds! I got heat Thanks SO Much. You saved me

[tonyc]

Thank you great video. Found the bad rollout switch by jumping the connectors. Furnace worked. Then saw the backdraft on the burners. So, it appears bad heat exchanger. Not surprising since the furnace is 27 years old. Going to call the furnace guys tomorrow and see what they say. But I'm expecting the worse (new furnace), but hoping for the best (some other issue that won't cost as much). You video has prepared me!!! :)
