Trouble shooting

For trouble shooting an air conditioner or heater its always important to ask your self one question before getting your hands in their-What is it doing and what is it not doing.This is the fundamental question to ask yourself no matter what machine your working on(washer dryer,dishwasher,microwave etc).If your unit is blowing air but not cooling 90% of the time your problem is in the condensor section of the unit.

It could be a capacitor and relay problem... or the compressor could be going bad...
Change the capacitor and start relay first and then see if that gets it going...

heat pump trouble shooting fema trailor i have a az75h18dacm1 self contained air cooled heat pump that wont work. cant find any info on this unit. have replaced the stat,the fan comes on only if it want's to

Normally the Fan only comes on when it is called for by the compressor, here is their web page that you can go to and pick your model and get their trouble shooting guide to repair your system, they also have a 800 phone number to help you. I am familiar with the unit but you need to look in there trouble shooting guide to properly troubleshoot your problem, you can call there 800 number and ask for help as well. Hope this helps.
