hlswaim Report post Posted August 13, 2012 I have 2 Airxcel roof mounted heat pumps installed on my '07 Fleetwood Bounder. Despite the Texas heat or the chill of Yellow Stone, I've had nothing but satisfactory service from both units until just the other day. We started smelling the scent of burning electrical insulation and couldn't identify the source until I saw what I believed to be, smoke coming out of the grill of the front unit. I immediately turned the unit off, hoping and praying the #2 unit wouldn't quit - a disaster in 100+ temps and humidity in Houston, TX! I tried the unit again today in my driveway but all I could get was blowing air (cool, not cold) without any scent of burning insulation. I've been told it could be a wire to the condenser(?) that is designed to do that(!) Am I looking at having to replace the unit or might this be a simple repair?

five Report post Posted August 17, 2012 The bottom line for the operation of HPs is that they work in moderate temps, not when it really gets cold. Okay in the fall, not the winter. Share this post Link to post Share on other sites
