Have HVAC Questions? Ask an HVAC Expert for Answers
Hello. Mark has not been here for quite a while now, but I can help you if you like.
Tell me a lot about your technical skills, and if you have a multi meter or not, I can coach you most effectively that way.
So far it sounds like the technician may have just added refrigerant, and not fixed the leak, and that the unit is off on is low pressure cut out switch.
If you can send me a well focused photo of the wiring diagram glued to the inside cover of the electrical controls box, I can coach you on how to check that.
We can go from there without a time limit.
