Full Diagnosis
Condenser Coil Temperature Sensor T3 Open or Short. Condenser coil temperature sensor T3 is open-circuit or short-circuit.
All Recorded Causes
Check T3 sensor wiring and connector for damage or corrosion. Verify sensor is properly seated on condenser coil. Measure sensor resistance and compare to chart. Replace T3 sensor if out of spec.
Verify Before Replacing Parts
- Confirm the exact Bryant model family and ductless systems context before acting on a generic code description.
- Confirm filter condition, blower operation, and coil cleanliness before replacing any controls — start by ruling out whether check T3 sensor wiring and connector for damage or corrosion.
- Measure airflow-related readings that match the symptom, such as temperature split or static pressure, and check whether verify sensor is properly seated on condenser coil.
- After the correction, run the system long enough to confirm the ductless systems fault does not return under normal load.
