To Next PageTo Next PageWhat to do if my ClimateMaster Tranquility TCH 012 Heat Pump has no fault code but isn't working?
If your ClimateMaster Heat Pump shows no fault code but is not operating correctly, and there is no compressor operation, see "Only Fan Operates". Check the compressor overload and replace if necessary. Reset power and check operation of the control board.
