STEP 1- remove snow on and around the condenser. We're talking REALLY clean it out here... (The condenser is the unit outside the house).
STEP 2- clean as much inside the condenser as possible.
STEP 3- pour hot water in the condenser to remove excess snow inside.
STEP 4- turn heat pump breaker for about 15 minutes then turn it back on.
If this process does not work, then it's time to make a service call.
Good luck & stay warm!
