Tony for Model Number FRA18EMT2 My unit has supplemental heat. I came home yesterday to a room that had heated up to 93 degrees even though the unit was st to 70. I powered off the device but I noticed that it kept blowing heat. I could see the heating element was still on even when the unit was turned off. I turned on the AC to try and cool the unit down and then powered off the unit. I noticed as I was unplugging it the AC I could see the heating element heating up again. Could it be the control panel or main baord?
