Any Hvac techs out there

Is it possible that snow build up in the exhaust pipe going through the roof could prevent the inducer motor from activating thereby preventing my heater from coming on?

But the heat from the flue gas will melt any snow that gets close to the cap, the only way it could possibly get over the flue is if the furnace wasn't running for a long period of time IMO.

I mean it did dump 13 inches in like 2 hours.

and 4 other trailers had the same problem

We had that exact thing happen at our office today, and we didn't get anywhere near as much snow here. It was a flat commercial roof though, not sure if that makes a difference.

That might be a world record, it was only coming down an inch an hour here.

You better have them extend the flue pipe up higher.

an exaggeration for sure.

Point being the snowfall was heavy

Yeah probably, although I haven't seen it nor do I know the layout of the roof or any of the other circumstances surrounding it, but it does seem to be a flukey thing to happen.

kind of followed this post but didn't throw in my 2 cents worth. but you would be right, if it is a standing pilot furnace it shouldn't have an idm. as a matter of fact even if it was hsi it probably wouldn't have an idm;if it is a mobile home furnace.
from what i've seen coleman and nordyne pretty muchly have a lock on the mobile home market and their furnaces have a combustion air intake motor which brings the air into the combustion chamber; it doesn't really send it out.
that being said, if the flue did get snow covered more than likely the upper high limit should have opened shutting down the furnace. some of these automatically reset, most are manual. could be a chance that mr. landlord reset it before cleaning the snow off.
side note, most, if not all mobile home roof jacks are pretty well fixed and it would not be a good idea to try and raise the flue. they are a two pipe system which brings combustion air in between the outermost pipe and the flue. 4" inside of an 8"

Which is correct. He cleaned the flue and hit the reset and whammo.

The 2 pipe system is what screwed us. 1 sorta covered, 2 entirely covered

This is interesting. I've seen many an e-penis battle on the Internet, but never centering around a knowledge of HVAC.

That's why you shouldn't call someone stupid when you don't have the full story.

Or just turning the furnace off and back on could reset it, next time I see a person wanting help fixing their furnace or A/C I will just sit back and watch like you.

HVAC question here - the motor on our air cond unit (the unit that sits outside with the fan) just went out yesterday. The motor was replaced three years ago almost to the day and it cost $400 ($320 for the motor). My question is, if I can get my hands on a motor, is it easy to replace myself? Is it really something that requires a trained technician?

Also, does anyone know how I can get a motor?

Comfort Products, Johnstone Supply, United Refrigeration. Look under "Air Conditioning Parts and Supplies" in the YP. Bought a motor for the furnace from United, years ago. GL. If it's the compressor motor, those can be sealed w/ the compressor, but it sounds like yours isn't. Write down all the info before calling. Good luck.
