    Heat pump intermittent cooling

    Hello, so I replaced the compressor on this heat pump and now it comes on and off basically whenever it wants. The pressures are 75 suction 220 head, on a 88 degree day. It will run normal for 40 minutes then everything shuts off. 5 minutes later it’s coming on again, mind you it never satisfied the tstat. Any help?

    Wheres the voltage dropping out when it shuts off? The whole system indoor and out door shuts down? I can think of a few things that would cause it to do that. Your meter is your friend.

    You mean we should find out why the old pump died before we replace it?

    That would be a good thing to do or at least have an educated reason.
