Check Outdoor Cond.
Check Comp. when it start
-
1. Check if the service valve is open
2. Check for refrigerant leakage(pipe connections,
heat exchanger) and charge refrigerant if
necessary
3. Check if there's any blockage on refrigerant
cycle(indoor unit/outdoor unit)
4. Check if additional refrigerant has been added
after pipe extension
Check whether 3 phase is reversed or opened.
