TROUBLESHOOTING STEPS:

Step 1: Check the Outdoor Ambient Hi/Low

• Monitor the outdoor ambient temperature to ensure it is within the acceptable range for the heating mode.

• Check for any abnormalities in the outdoor ambient temperature readings that may indicate issues with defrosting or oil return.

• Ensure that the outdoor ambient conditions are suitable for the heating operation.

 

Step 2: Check by 4 Point Temp Check

• Perform a 4-point temperature check to assess the system's performance.

• Check temperatures at various points, including the indoor and outdoor units, to identify any irregularities.

• Verify that the temperature differentials align with the expected values for the heating mode.

• Inspect for any signs of malfunction or inconsistencies in the temperature readings.
