Question about Samsung Heating & Cooling
Most likely you have a stuck check valve....
When the reversing valve switches for heating, the check is not opening so the pressure builds till the high limit shuts it down and then the compressor shuts down...
The pressure then spins the compressor backwards which makes alot of noise...
Find a certified refrigerant tech. that can diagnose the system and change out the bad valve...
This is NOT a DIY project!!
