TEMP SENSOR ERROR 4 (Eva In)
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.
DETAILS BELOW:
The “Eva in” sensor location.
The “Eva In” sensor is located on the sealed system lines.
With the top of the unit off, you can easily check the status of the “Eva In” sensor from this connector.
The sensor from this test point will read with the harness:
Plugged in = 4k
Unplugged = 10.6k
At room temperature approximately 70 degrees. It also may be necessary to remove the wire retainers onthe connector to get a good connection.
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.
