Have a Coleman Mach roof air unit on my enclosed car trailer. Had it installed with heat strips. Been using it for about six years now with no issues. Now for some reason the heat side of the unit is not putting out any heat at all.

Disclaimer.....prior to anyone replying that the heat strips don't make any difference and they're probably working fine, please know that they are in fact NOT working. I know the temperature they have put out in the past. When it's 60 degrees outside and the air coming out of the unit is colder than that there's an obvious issue.

AC side is working great. Very cold. I realize this doesn't have anything to do with the heat side of the unit.

As always, thank you in advance.

the heat strip is a complety seperete deal, more than likely its burned out, drop the lower panel off, look for it looks like a small heating element, ck voltage on connector, is 120 volts. simple replacement...good luck

Check the breaker, mine is on a different one. It would trip if the trailer was plugged into a gfi outlet. The breaker would trip but not flop over like it was tripped. And check the thermostat

Excellent. Sounds simple enough. Thank you. Now I just need to check availability of parts.

I will double check breaker to be safe. I'm pretty sure the unit is all on one breaker though.

The thermostat is a dial on the face of the unit. I can only turn it so far on the red part of it.

Update....

Ordered a new heat strip assembly and plugged it in. All good. $50 for the parts and 10 minutes to install.

Thanks again for feedback.

Buck

cool...yes replaced them before

Don't lie Buck. We know this is on your house (rastaboatin)

I work at an RV dealership and can help you out if it goes bad.
