If you’re looking for help fixing your Tempstar air conditioner, look no further! Our comprehensive Tempstar air conditioner repair guide will explain common issues, provide troubleshooting tips, and show you how to read your model’s error codes.

CODE: On solid, no flash
PROBLEM: Normal operation – with communicating Control.

CODE: Off
PROBLEM: Normal operation – No call for cooling with 2-wire connection or indoor unit not pow-Offered.

CODE: 1 pause
PROBLEM: Normal operation.

CODE: 16
PROBLEM: Communication with wall control lost. Check wiring to wall control, indoor and outdoor units.

CODE: 31
PROBLEM: High pressure switch trip. Check refrigerant charge, outdoor fan operation and coils for airflow restrictions.

CODE: 32
PROBLEM: Low pressure switch trip. Check refrigerant charge and indoor air flow.

CODE: 45
PROBLEM: Outdoor unit control board has failed. Control board needs to be replaced.

CODE: 46
PROBLEM: The control voltage is less than 15.5v for at least 4 seconds. Compressor and fan operation not allowed until control voltage is a minimum of 17.5v. Verify control volt-age.

CODE: 53
PROBLEM: Outdoor air sensor not reading or out of range. Ohm out sensor and check wiring.

CODE: 55
PROBLEM: Coil sensor not reading or out of range. Ohm out sensor and check wiring.

CODE: 56
PROBLEM: Improper relationship between coil sensor and outdoor air sensor. Ohm out sensors and check wiring.

CODE: 72
PROBLEM: Compressor voltage sensed after start-up, then absent for 10 consecutive seconds while cooling demand exists. Possible causes are internal compressor overload trip orloss of high voltage to compressor without loss of control voltage. The control will continue fan operation and wait 15 minutes to attempt a restart. Fault will clear when restart is successful, or low voltage power is cycled.

CODE: 73
PROBLEM: Compressor voltage sensed when no demand for compressor operation exists. Contactor may be stuck closed or there is a wiring error.

CODE: 74
PROBLEM: Compressor voltage not sensed when compressor should be starting. Disconnect may be open or contactor may be stuck open or there is a wiring error.
