Full Diagnosis
Compressor open run circuit.
All Recorded Causes
Current is detected in the start circuit but not the run circuit. Check run winding, run capacitor, contactor, compressor R terminal, and wiring.
Verify Before Replacing Parts
- Confirm the exact Rheem model family and ac and heat pump context before acting on a generic code description.
- Verify current draw, overload status, and control signal before condemning the compressor or drive, given that current is detected in the start circuit but not the run circuit.
- Look for upstream conditions such as airflow or charge issues that may be pushing the compressor into protection, and check check run winding, run capacitor, contactor, compressor R terminal, and wiring.
- After the correction, run the system long enough to confirm the ac and heat pump fault does not return under normal load.
