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
