Why does my heat pump fan run and the compressor won't kick on? Unit inside, downstairs and thermostat seem to be operating properly. Is there anything I can do myself to troubleshoot the problem??

Why would my heat pump's fan run constantly and the compressor not kick on? ---Thermostat and unit downstairs seem to be operating fine. Is there anything I can do myself to troubleshoot the problem?

Which fan? Inside or outside?

Outside

How do you know the compressor outside is not running? Did you test it or use a Amprobe to see if it is drawing power?

Haha!---No, unfortunately, I'm not that versed in these types of repairs----Can't you tell just by listening---It usually makes a loud "baaarrrrrooooom" when it first kicks on

I'm hoping it's something simple...

Yes they do make a different sound when the compressor is running but if you have no skills in this industry it will be a tuff repair.

One thing you can do is kill the power to the outside unit then look for a loose or burnt wire going to the compressor or contactor. If found repair and put back in service. Good luck.

Thanks!
