Oh really good to know well my ptac is my heater also. I am going to rent the condo out soon anyway I'm buying a house within a couple weeks. I get my inspection and termite done next Wednesday. This islandaire junk started working again about 2 hours after I wrote the post all I did was unplug it for a day and plug it back in. I've had so many problems it is such junk. The only reason I got it was to use the existing wall sleeve from my old one. HAPPY FOURTH EVERYONE. I'm sure you're all off I have to work.
