I have a duo therm rooftop ac unit that is not working. The fan kicks in, but the compressor doesn't seem to even try to kick in. I'm assuming that I am going to have to replace the unit, but is there...
Just throwing parts at one and not really knowing what you are looking for usually doesn't give the desired results. The first step is to see if the run voltage is even getting to the compressor. Unfortunately, a lot of people on here think that a capacitor is the magic cure-all... It's not.
