Take your volt - ohm meter outside ( yes , I know , into the snow ) . Check , very carefully for 240 VAC coming into and out of the heat pump disconnect . Carefully check to see if the 240 VAC makes it into the unit , at the contactor .

Check for loose connections of the line voltage wiring , AFTER you turn off the power .

Still , with the power off , look for the small low voltage wires coming from the house . Check for loose connections . One of these small low voltage wires will be the C - Common 24 VAC wire to one side of the furnace transformer . One will be the Brown or Orange wire going to the reversing valve .

You probably have other low voltage wires , to . Going to out door air temperature sensor or other things .

Try to post a clear / sharp photo of the inside of the heat pump and of the wiring diagram .

These are the things I would start out doing . Hopefully some one will come along that knows more about heat pumps , than I do .

God bless

I'm not a HVAC specialist, so take this with a grain of salt, but define "snow covering whole unit." Can you take a pecan post it? I know you got blasted with snow but how much I don't know. Depending on how covered it is can you see the coil(s) outside your unit and inside through the fan? If so, do you see ice covering the coil? It's always beneficial (or necessary) to clean snow from the HP, though you don't want to bang or it on the unit to remove the snow (or ice).
