Full Diagnosis
High Torque Event. High-torque event detected.
All Recorded Causes
Check for mechanical binding or blockage in the compressor. Inspect refrigerant charge and system pressures. Verify supply voltage is within specification. Check inverter drive output waveform. Board retries after 10 minutes.
Verify Before Replacing Parts
- Confirm the exact Bryant model family and heat pumps context before acting on a generic code description.
- Confirm board LEDs, wiring polarity, and model compatibility before replacing control boards — this Bryant fault points at check for mechanical binding or blockage in the compressor.
- Check for intermittent communication faults caused by connectors, moisture, or damaged harnesses, and rule out inspect refrigerant charge and system pressures.
- After the correction, run the system long enough to confirm the heat pumps fault does not return under normal load.
