TEMP SENSOR ERROR 3 (DUCT OUT)

TEMP SENSOR ERROR 3 (Duct Out)

Cause

Temperature is abnormal

Solution

Check the sensor if its in range or at least is not “open” or “Shorted”

If the sensor is good replace the main PCB.

If the sensor is not good you will need to replace the entire Duct Assembly.

The location of the “Duct Out” sensor.

While the sensor can not be accessed easily, it can still be checked to either condemn it or validate it is good.

With the top of the unit off, you can easily check the status of the “Duct Out” sensor from this connector.

The sensor from this test point will read with the harness:

Plugged in = 16k

Unplugged = 53k

At Room Temp. approximately 70 degrees. It also may be necessary to remove the wire retainers on the connector to get a good connection.

*If the sensor is determined to be bad, you will have to replace the whole Duct Assembly. If the sensor is good replace the Main PCB.

Note: If any part of the sealed system or sensors or blower located on the Duct Assembly is defective, you must replace the whole Duct Assembly.
