Thank you, your video kept my kids and me from freezing our butts off. Mine looked just like the one in your video. Took it apart and found a spiderweb. My furnace was running nonstop and blowing out cool air and now it's working great. Thanks again!
Thanks for posting these, guy. I have a Coleman MH furnace and see most of those downflow models are quite similar. You give me confidence to do things on my own when I can.
Thank you so much, for real. I paid for advice through a handyman app, pretty sure it was just a bot. Sent me on the wrong path of fixing more than once. Watched your video, for sure was the problem I was having, so thanks you really saved my ass in the cold. So from the bottom of this Wisco heart, bless you and yours.
Thanks for the video! I do PM and repairs on this and the pilot version here in NW Washington. Mine are LP gas, so spiders rarely make it into the smaller orifice, plus frequent use burns the little boogers up. Running LP, hot spots sometimes develop, so I check chambers every service call.
Exactly what mine is doing and had several furnace guys look at it and said that's as good as it's going to get. I questioned the orifice and they looked at me like I was an idiot and said "well it obviously has a flame" ... I would bet this is my problem.
I have this same furnace. I call for heat the inducer motor comes on. And then the gas valve comes on and I have a flame. But flame goes out in 10 to 30 seconds before the blower motor even comes on. Any idea what’s going on?
That could be your igniter sensor is no good. Check to see on the circuitboard if you have one if the yellow light is solid or blinking also could be bad gas valve.
Would this cause a short cycle?(mgha-077aafc-02) I just rented this mobile home, after hours of trying to get the pilot lit the furnace turns on them off shortly right after , then turns on again and repeats ..
No sounds like it’s over heating check for blockage in filters floor vents indoor coil if you have ac blower could not be running correctly if that doesn’t help could be something else like limits or gas valve hope this helps please subscribe if you haven’t already thanks 👍
Could be possible bad transformer or fuse on the circuit board also could be the upper limit switch that tripped try that first 👍thanks for watching 💪🏻💪🏻💪🏻🤜🤜
Someone in my company found one of these and said bad gas valve. They sent me to change it out and still same problem. Clean out webs problem solved 😂😂

Thank you for your help
I have Nordyna MGHA 070 AAFC-02 and I had the same problem.
Exactly fixed the problem. Bless you for posting.
Thank you for this video. Here on out, you have my full support. You save me a lot of money.
Good to know, should save many from jumping down unnecessary rabbit holes! Thanks for sharing.

Ive been waiting for this video. I swear 90% of my trouble calls in mobile homes we found spiders in the orifice ! We called them gas spiders!
Just saved us a boatload of money compared to having a tech come out. Thank you for your videos!
Thanks so much. I had the same issue with my uncles Coleman heater and it was in fact a spider web blocking the hole. Works great now!
Awesome
Very nice of you to share your knowledge.
Thank you
Those models had a bad heat exchanger flaw where they bulge and burn a hole on the left side.

Update?
I have a spider web in my Coleman mobile home furnace again.
How do you know when a furnace this style needs to be replaced?
I also have intertherm unit that run and shut off. I have had a HAVC worker come. He said no problem. Can you give some suggestion please.
Please subscribe if you haven’t already How long does it run for?
@@Victoryhomeservices209 5minutes sometimes and sometimes for hours then start shutting on and off.
@@nicolevasser6092 it could possibly be your igniter/sensor
@@Victoryhomeservices209 okay thanks
Is it always spider webs or some kind of restriction in the orifice to cause a small flame like that?
Can it cause your pilot light to blow out too?
I'm doing hvac and I live in a manufactured home and we usually always get a spider the first time I fire it up
I have this same furnace. I call for heat the inducer motor comes on. And then the gas valve comes on and I have a flame. But flame goes out in 10 to 30 seconds before the blower motor even comes on. Any idea what’s going on?
Is it me or does it seem like spiders always make webs in these mobile home furnace orfices residential furnaces never seem to have this problem
Yea it is very common
How do you locate the flame sensor on a mobile home intertherm furnace? It keeps shutting on and off
@@satbobsmith7261 thank you
Can you bypass the inducer motor
I have an interterm furnace, the flame starts up then quits. Just blows cool air as a result. The furnace clicks a lot.
That could be your igniter sensor is no good. Check to see on the circuitboard if you have one if the yellow light is solid or blinking also could be bad gas valve.
I have the same furnace. My flame comes on and goes out before the blower even kicks on. Did you figure out the problem?
@@kevinbalcer8957 Found out it was starving for air. The guts of the chimney had collapsed. Works fine now.
Could something in this unit this also cause the air not to blow as cold?
Yeah it could trip one of the high limits that can cause just cold air
🎉thanks to your video I just saved a lot of money
