Full Diagnosis

Compressor open run circuit lockout.

All Recorded Causes

Open run circuit detected repeatedly. Check run capacitor, compressor run winding, wiring, contactor, and control before resetting.

Verify Before Replacing Parts

  1. Confirm the exact Rheem model family and ac and heat pump context before acting on a generic code description.
  2. Verify current draw, overload status, and control signal before condemning the compressor or drive, given that open run circuit detected repeatedly.
  3. Look for upstream conditions such as airflow or charge issues that may be pushing the compressor into protection, and check check run capacitor, compressor run winding, wiring, contactor, and control before resetti….
  4. After the correction, run the system long enough to confirm the ac and heat pump fault does not return under normal load.
