I replaced the left hand loop pump which I confirmed was not working. I flushed the heat pump loop side to get any air out, pressurized the ground loop to 65 psi. I restored power to the system and confirmed both pumps are operating. I burped the air out of the pumps. Unit operates normal.
On arrival found system not operating found blown fuses replaced glass fuses .found one left side pump not operating.unit is running on one pump.customer paid in full .
