COMMUNICATION ERROR Definition: Communication issue between the Main PCB and Display PCB. Cause Supply Voltage Issue. Solution Make sure the supply voltage to the unit is within correct range. Check the spec sheet to see if the unit is 115V/208V/230V and that the actual supplied voltage +/- 10% of the rated voltage required. Cause Wiring […]

WAC_E3
REFRIGERANT LEAK ERROR Cause (If code is intermittent or unit is cooling correctly): Main PCB or Temperature Sensor defect. Solution Try Reset. If Reset does not work replace Main PCB and Temp Sensor(s). Cause Sealed System Leak. Solution Look for leaking sealed system component. Look for oil on tubing. Replace leaking part and repair sealed […]
