Customer has a mini split in a room in which he stores wines. When turning on the mini split hit with fan, only the fan operates however, when you call for cooling the fan, nor the outside unit turns on. And checking the voltage I was receiving line voltage of 120 on L1 and 120 on L2 and 248 across L one and L2 however, when checking DC voltage across L1234L2 to three I was not getting any DC voltage which is an indication that the indoor board is not communicating with the outdoor board. The PCS control board as well as the filter board in the head unit needs to be replace code is PCB two for the control board and PC. The one for the fan control board. Additionally, the customer wanted an estimate to replace and install a new line set cover for his split system and additionally, I’m also recommending for the mini split had to be pulled apart and clean. The customer stated that he will discuss with his wife this evening and give the office a call to schedule.
