Full Diagnosis
Compressor Motor Temp Out of Range Event. Compressor motor temperature is out of range.
All Recorded Causes
Check refrigerant charge and system pressures. Inspect for restricted airflow. Verify compressor motor temperature sensor. Allow compressor to cool. Inspect for overloading conditions. Board retries after 5 minutes.
Verify Before Replacing Parts
- Confirm the exact Bryant model family and heat pumps context before acting on a generic code description.
- Verify airflow first, then confirm operating pressures and temperature relationship before adjusting charge, since check refrigerant charge and system pressures.
- Look for restrictions, iced coils, or dirty heat-transfer surfaces that can mimic a charge problem, and separately confirm inspect for restricted airflow.
- After the correction, run the system long enough to confirm the heat pumps fault does not return under normal load.
