Full Diagnosis
High Torque Lockout. High-torque lockout active for 2 hours.
All Recorded Causes
Diagnose root cause of repeated high-torque events. Check for compressor mechanical binding, refrigerant overcharge, or restricted refrigerant circuit. Allow lockout to expire (2 hours) or power cycle after root cause is corrected.
Verify Before Replacing Parts
- Confirm the exact Bryant model family and heat pumps context before acting on a generic code description.
- Verify airflow first, then confirm operating pressures and temperature relationship before adjusting charge, since diagnose root cause of repeated high-torque events.
- Look for restrictions, iced coils, or dirty heat-transfer surfaces that can mimic a charge problem, and separately confirm check for compressor mechanical binding, refrigerant overcharge, or restricted refrigerant….
- After the correction, run the system long enough to confirm the heat pumps fault does not return under normal load.
