What to do if my Carrier 68G5-105 displays a Suction Pressure Transducer Failure?
If your Carrier Air Conditioner shows a Suction Pressure Transducer Failure, it could be due to the sensor being unplugged, defective wiring, or the suction pressure transducer itself failing. Make sure the sensor is properly connected. Inspect the transducer voltage and wiring for any issues. If necessary, replace the sensor or repair the wiring.
What to do if my Carrier 68G5-105 displays a Discharge Pressure Transducer Failure?
If your Carrier Air Conditioner displays a Discharge Pressure Transducer Failure, the cause may be a disconnected sensor, faulty wiring, or a failure of the discharge pressure transducer. Ensure the sensor is plugged in correctly. Check the transducer voltage and wiring for defects. Replace the sensor or repair the wiring if needed.
What to do if my Carrier Air Conditioner displays a Humidity Transducer Failure?
If your Carrier Air Conditioner displays a Humidity Transducer Failure, it could be due to the sensor being unplugged, defective wiring, or the humidity transducer malfunctioning. First, ensure the sensor is properly plugged in. Then, check the transducer voltage and wiring for any issues. If necessary, replace the sensor or repair the wiring.
What to do if my Carrier 68G5-105 displays a Main Left Probe Failure?
If your Carrier Air Conditioner is showing a Main Left Probe Failure, the problem could be that the sensor is unplugged, the wiring is defective, or the main left evaporator return air temperature sensor has failed. Ensure the sensor is properly plugged in. Check the sensor resistance and wiring. Replace the sensor or repair the wiring if necessary.
What to do if my Carrier Air Conditioner displays a Main Right Probe Failure?
If your Carrier Air Conditioner shows a Main Right Probe Failure, it might be because the sensor is unplugged, the wiring is defective, or the main right evaporator return air temperature sensor has failed. Ensure the sensor is properly plugged in. Check the sensor resistance and wiring. Replace the sensor or repair the wiring as needed.
What to do if my Carrier 68G5-105 Air Conditioner displays an Ambient Probe Failure?
If your Carrier Air Conditioner displays an Ambient Probe Failure, it could be due to the sensor being unplugged, defective wiring, or the ambient temperature sensor failing. You should ensure the sensor is plugged in correctly. Check the sensor resistance and wiring for any issues. Replace the sensor or repair the wiring if necessary.
