So, a buddy of mine has a Coleman Furnace model# DGAF100CDJ. He called me telling me about an issue he is having and it kinda has me stumped.
So the full story is, he and his wife were going out of town for the weekend. They switched the furnace from heat to A/C due to the temps in our area projected to get up into the high 70's, low 80's. While they were gone, or weather changed and it was supposed to get super cold again on Sunday. He called his mother in law and had to go to their house and switch the thermostat back to heat from cool.
They got home and he noticed his house was at 53*. He checked to make sure she switched it back, and she had forgotten. So, he immediately switched from cool to heat and he heard the heater kick on, so he thought. He went to the furnace and it had a error code that I can't remember what he told me it was. He said got the code to clear and it went to fire again and he could hear the fan kick on, then flame, and about 10 seconds later he said it was like someone stuck a metal rod in the blower motor stopping the fan, and it just smelled like the fan was burning up.
So..... He immediately shut it off. He started browsing forums, trying to get answers with no luck. Someone suggested he try shutting the heat/cool mode to off, and switching the fan to fan only. He said the fan runs just perfectly fine that way, but as soon as he would switch it over to heat and auto fan, the same scenario with the blower motor happens again.
I am stumped, as is he. Just thought I'd post this up to see if any HVAC guys might be able to shed some light on this?
Thanks!
