Full Diagnosis
Compressor protector trip.
All Recorded Causes
Command for compressor operation is present but no compressor current is measured. Check compressor wiring, contactor, capacitor/start components, thermal overload, line voltage, and compressor condition.
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 command for compressor operation is present but no compressor current is measured.
- Look for upstream conditions such as airflow or charge issues that may be pushing the compressor into protection, and check check compressor wiring, contactor, capacitor/start components, thermal overload, line vol….
- After the correction, run the system long enough to confirm the ac and heat pump fault does not return under normal load.
