Update. There was not a lot of ice behind the panel, a little on top of the condenser and the (what I am guessing is an air vent), was totally frozen. One fan was froze up. Thawed it all out, checked the thermostat by placing in chest freezer and it checked out, checked thermister in ice water and it went up with the readings, when placed in ice water to around 13k. Had continuity on the heater. I tried checking continuity on the fans but meter would not change or make a high pitch sound, so I am guessing they are both bad. I have not checked prices on them but prob can't afford at this time anyway. Got everything back together and I give up. I guess my best bet is to call a repair service and see what they charge to trouble shoot it. Just wanted to say thank you for all the support and advice.
