Window ac/heat question
I have a 20 yo ComfortAir cooling and heat window unit for my shop. The air works fine but the heat strips don't work. I don't think this unit is a heat pump. Help PLEASE.

Couldn't you begin diagnosis with a simple multi-meter check of whether the heat strips are getting power or not?

I found out why the heat isn't working, I was able to get to the heat strips and reached down to the bottom and could feel the broken part. The heater is like a spring, can it be reattached or can I buy a generic type heat spring to replace it?

Take a picture of the element. I might be able to find you something. you are going to have to remove it one way on another.

Also the heat spring is behind the cooling unit and I'm trying to figure out how to remove the cooling unit part, any suggestions?

If it is a window unit, you would generally remove the outside cover. A lot of times, the entire unit will slide right out of the cabinet part.

If I can't find a replacement part, can I just restring some new heating element wire?

I am worried about you sticking your hand down into this thing...
EVEN WITH THE UNIT UNPLUGGED... IF there is a big capacitor in there you could really get hurt.... Do you have any electrically experienced friends who could supervise this activity ? Or at least check it for dangerous components first ?
