Full Diagnosis
Compressor open start circuit.
All Recorded Causes
Current is detected in the run circuit but not the start circuit. Check start winding, start capacitor, start relay, compressor S 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 run circuit but not the start circuit.
- Look for upstream conditions such as airflow or charge issues that may be pushing the compressor into protection, and check check start winding, start capacitor, start relay, compressor S 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.
