Thanks, and since I am learning all this stuff I will be posting more questions then answers on this site. Sorry for being such a burden!
The heater was replaced because there was a bunch of frost on the coils and I checked the heater with multimeter and I got no reading. Just by looking at the heater I looked like it was blown out. btw, I am not sure I know how to check the compressor like you explained. How do I check the cold control?
