Fault Code Troubleshooting Guide

Ambient Temperature Sensor Short or Open or Ad Error (Ambient temperature sensor circuit is not functioning):

Loose connection or damaged wire-

•Turn off power at the circuit breaker / fuse box.

•Check that connector CN212 on control board is seated.

•Check wires for damage.

Ambient temperature sensor is shorted or open-

•Unplug ribbon cable from CN212; check resistance between pins 1 and 2 of the ribbon cable connector. Refer to chart #1 (p.33) for expected resistance value. If the measured resistance is >40kΩ or = 0Ω, the thermisitor is faulty.

•Replace thermisitor assembly.

Control board faulty-

•Replace control board.

•If replacing the control board doesn’t resolve the issue, contact technical support.

Upper Temperature Sensor Short or Open or Ad Error (Upper temperature sensor circuit is not functioning):

Loose connection or damaged wire-

•Turn off power at the circuit breaker / fuse box.

•Check that connector CN204 on control board is seated.

•Check wires for damage.

Upper temperature sensor is shorted or open-

•Unplug ribbon cable from CN204; check resistance between pins 1 and 2 of the ribbon cable connector. Refer to chart #2 (p.33) for expected resistance value. If the measured resistance is >200kΩ or = 0Ω, the thermisitor is faulty.

•Replace thermisitor assembly.

Control board faulty-

•Replace control board.

•If replacing the control board doesn’t resolve the issue, contact technical support.

Lower Temperature Sensor Short or Open or Ad Error (Lower temperature sensor circuit is not functioning):

Loose connection or damaged wire-

•Turn off power at the circuit breaker / fuse box

•Check that connector CN204 on control board is seated.

•Check wires for damage.

Lower temperature sensor is short or open-

•Unplug ribbon cable fron CN204; check resistance between pins 3 and 4 of the ribbon cable connector. Refer to chart #2 (p.33) for expected resistance value. If the measured resistance is >200kΩ or =0Ω, the thermisitor is faulty.

•Replace thermisitor assembly.

Control board faulty-

•Replace control board.

•If replacing the control board doesn’t resolve the issue, contact technical support.

Discharge Temperature Sensor Short or Open or Ad Error (Discharge temperature sensor circuit is not functioning):

Loose connection or damaged wire-

•Turn off power at the circuit breaker / fuse box

•Check that connector CN212 on control board is seated.

•Check wires for damage.

Discharge temperature sensor is short or open-

•Unplug ribbon cable from CN212; check resistance between pins 3 and 4 of the ribbon cable
