My furnace inducer motor is kicking on and off repeatedly but nothing else will kick on..any clue what this issue is? I think it’s something simple but I can’t figure it out. 15 degrees here…if I can’t figure it out I’m going to call a tech tomorrow

[@jimbarron8688]

The flame sensor signal is very small measured at approx. 4-7 micro amps DC. Any oxidation or the build up of mercaptan on the sensing rod will impede this signal and shut off the gas valve circuit on flame failure. Keeping it clean with a few light passes of very fine steel wool is the best prevention.

You are a lifesaver. I noticed the heat wasn’t kicking on and the flame would only ignite for like 10 seconds then shut off. I removed the filter to make sure it wasn’t an airflow issue and it still happened. The flame light on the control board would blink when the flame was on. I cleaned the flame sensor with some sandpaper and reinstalled, now the flame stays on and the light on the board is solid instead of blinking so I think it worked. Seriously huge thanks to you for saving me the money and headache.

Interesting, I can’t tell on my unit which part of two is the flame sensor. Theres two possibilities. But my heater sometimes works and sometimes doesn’t. It seems to work after turning my system off for a bit and then turning it back on. So now I’m wondering if my thermostat control limits how many times my heater can turn on in a given amount of time, like an hour. I’ve heard that some systems have controls to set the limits on how many times a heater or AC could turn on in an hour or so.

[@DIYwithMichaelBorders]

Thanks for watching, that’s definitely a possibility. In the meantime, are any of your floor vents throughout your home covered in any way? All it takes is one floor vent to be covered by a rug or a dresser, causing a backflow of air pressure that the furnace can detect and lead to a system shut down for safety purposes.

No brush guys you don’t wanna scratch that. Use a dollar bill or a piece of the finest wet dry sandpaper that sold that’s just about like smooth paper you don’t wanna scratch that ride or will start collecting carbon and dust and dirt and everything on it which causes the problem.

[@teegees]

This is indeed a very common issue. You can also use fine grit sand paper to clean the sensor rod. I find it’s more effective than the brush as it covers more surface area in a single stroke, and you can modulate the grinding pressure more easily as well.

Is it not odd that the blower comes on well before the inducer does? The inducer has failsafes on it which cause same issue but i always thought it would turn on the inducer to clear any residual in the exchanger then establish flame to heat the exchanger finally turning on the blower so it doesnt blow a bunch of cold air in..

Good morning, we are drinking our morning coffee answering any and all questions for the DIY community. This is usually caused by a worn out blower fan mount. The large blower fan can begin spinning in a slightly offset manner while furnace is running. After furnace turns off, the blower fan begins to wind down and once at a slower rotation speed, it sometimes hits the mount and makes a bang or clunk sound.

I have this exact set up on my gas furnace. I pulled out the flame sensor and cleaned it. Its throwing a code: 6 steady light flashes. My furnace turns on and heat then shuts off. Flashing 6 light code. I changed the flame sensor with a brand new one. Can you help me with this??? Thanks :)

[@DIYwithMichaelBorders]

@@lowceez2 Thanks for watching, by chance have you replaced your Limit Switch? Below is a helpful video link that shows the replacement process as this may be your cause. kzbin.info/www/bejne/qGq6qWyLbLyhjcksi=C2rW9bZJIhJb3BoL 🧰

Hmmm mine shuts down after about a minute. Cleaned this guy and still doing it. Any other suggestions or should I just replace it? Thanks

[@DIYwithMichaelBorders]

Bummer…have you replaced the filter? A dirty filter will cause furnace to do this as well.

[@michaelg4433]

@@DIYwithMichaelBorders filter is pretty knew. I had it all off for about a day and figured I’d just give it a shot again after cleaning it some more… voila! It’s working now. Not sure if I just didn’t clean it well enough the first time or not

So for this to be the problem the flames will light for a couple seconds? Mine stops without the flames lighting

[@DIYwithMichaelBorders]

@@tardis4125 Thanks for watching, any update? By chance is anything covering any of the vents throughout home? Blocked vents can lead to this furnace behavior.

[@tardis4125]

@DIYwithMichaelBorders no blocked vents. Checked the flue and that good to. Went through all the wire connections to make sure nothing was loose. It turned on after, but only lasted about an hour then turned off again. Now it won't light again. I'm going to look at it again this weekend. Mess with one wire at a time and see if one will make it work, then ill know that's the problem

[@DIYwithMichaelBorders]

@@tardis4125 Thanks for the reply. It may be a Flame Sensor or Limit Switch in its early stages of failure and acting sporadically. Below are helpful links. kzbin.info/www/bejne/ppbZd4CunsSfrMksi=sJdGEFU_p4bdGgnr kzbin.info/www/bejne/qGq6qWyLbLyhjcksi=RnYNbERCrMyJu0y7 🧰

[@tardis4125]

@DIYwithMichaelBorders thanks. I'm going to try to narrow it down to something first. If not I'll just start replacing stuff till it works hopefully

[@DIYwithMichaelBorders]

@@tardis4125 Definitely understandable. 👍

[@fourknotsnowhere]

my flame sensor is right next to the pilot light. the pilot stays lite and the burner turns on, but the heater only stays on for about 10 to 20 seconds at a time. i cleaned the sensor and bypassed the thermal fuse above it. its still doing the same thing. brand new filter, and the output register is completely open. any tips to solve this issue? its a really old ruud furnace, the flame sensor wire looks like a 1/4" copper tube instead of a wire.

[@DIYwithMichaelBorders]

Thanks for watching, any update? Do you see any sporadic behaviors with burner tubes and flames? If the flames are not coming out of burners in a straight, organized manner, sensors will pick up on that sporadic behavior and shut system down.

[@fourknotsnowhere]

@@DIYwithMichaelBorders nothing like that. the only update i have is that ive spent $300 on electric space heaters and its 60 degress in the house. im working on sealing all the windows up with plastic right now

[@DIYwithMichaelBorders]

@@fourknotsnowhere Thanks for reaching back out and sharing your update. That’s a different approach than we expected. 😎 Double checked that all connections and screws are properly secured on the control panel.

[@fourknotsnowhere]

@@DIYwithMichaelBorders i cant even find a control board in this old thing. is it possible that its so old it doesnt have one? theres a fan controller dial in a honeywell metal box. but not a mainboard from what i can see

[@DIYwithMichaelBorders]

@@fourknotsnowhere Possible, not extremely knowledgeable on units from way back when…🤔

[@womenarentreal]

I tried this hoping for the outcome like others had but my furnace flame still turns on and shuts off after a while and eventually the whole system shuts off. I’m not sure what’s next, should I replace the flame sensors?

[@DIYwithMichaelBorders]

Thanks for watching, that’s a bummer. Have you replaced the filter? A dirty filter will cause furnace to perform this way.

[@ChoicesHabitsAttitudeLuck]

mine is stopping then lighting up again. is that normal? like it's auto stopping once it reach a certain temperature

This was the problem with our furnace. Dang! Wish we see this video. We just paid $190. All he did was clean the flame sensor 😔 and told us the replacement of the flame sensore would cost us $130 🤯 He will come back next week to replace it

[@DIYwithMichaelBorders]

Thanks for watching, a faulty Flame Sensor will definitely do it. 😎👍

[@RedPill780]

My furnace takes more than 3 hours to warm up the house on the coldest winter days, and it's been turning off and back on again after blowing air. The cycle happens up to 8 times in the first hour, and only in the morning. Why does this happen only when I heat the house for the first time in the morning?

[@DIYwithMichaelBorders]

Thanks for watching, it’s possible that your furnace is short cycling. We recommend inspecting your filter, it dirty, it should be replaced. If a new filter doesn’t help, inspect your blower fan. If it’s very dirty, the added weight of the dust or ash-like soot can lead to this. Cleaning it will go a long way.

[@RedPill780]

@@DIYwithMichaelBorders Thanks for the reply.

I'm working on a Mr.Cool furnace. Brand New, didn't run more than 2 weeks and it started having the issue described in this video. Its a pretty clean looking sensor, and has worked at times without failing. but then starts failing and don't stop. It is strange that the furnace doesn't give an error code of it, or go into a lock-out status, but just keeps trying to starts, starts, and then stops, restarting the process all over.

[@DIYwithMichaelBorders]

Thanks for watching. Being only two weeks old, you shouldn’t have any issues whatsoever, that’s a bummer. By chance, are any of your vents blocked by either a rug, couch, or any type of furniture? A blocked vent, mainly on the floor, can cause back-pressure and lead to furnace operating with sporadic behaviors as you mentioned. If not, is your furnace covered under warranty by the company that installed it?

[@NarFlux]

@@DIYwithMichaelBorders the gentlemen whose furnance it is I am working on, says it should be covered under warranty. The pressure switch does not seem to be what is cutting it out, so I don't believe it is a vent issue. The inlet and outlet vents are not blocked. The Flame Sensor does not give very consistent ohms readings when I remove it and test it. So I am wondering if it is just a defective flame sensor. Do you happen to know what is happening in the board to sense the 10 mA it is supposed to be generating? What circuit board component could be checked as a possible cause?

[@DIYwithMichaelBorders]

@@NarFlux Thanks for the follow up, that’s very possible. The flame sensor should have constant ohms. Do you see any sporadic behavior in terms of the burners? In other words, are the flames coming out of burner tubes straight or is any of the flames breaking their constant straight projection and fraying out or back? If so, additional sensors will need to be replaced. However, being brand new, it shouldn’t be any of the sensors…🤔

[@NarFlux]

@@DIYwithMichaelBorders the flames come out of the burner tubes without any abnormalities. Straight and steady. Its just something cuts the power right out. The flame sensor shows about 57 Volts to it when the system is powered and trying to start.

[@DIYwithMichaelBorders]

@@NarFlux That is a great place to start.

[@stillcarlG]

Would this still be the issue if the system works sometimes? Or is there something else wrong. My furnace will work just fine for a week then it will act up like the video states

[@DIYwithMichaelBorders]

Thanks for watching & it’s very possible. There may be a part that is intermittently working, in other words...in its early stages of failure.
