How to Fix / Troubleshooting
Safety first: Turn OFF power before accessing the outdoor unit.
- Step 1 – Confirm mode setting: Ensure the remote is set to the correct mode (COOL or HEAT) and not in AUTO if behavior is confusing.
- Step 2 – Listen for valve shift: When changing modes, listen at the outdoor unit for the reversing valve shifting. No sound may indicate a stuck valve or dead coil.
- Step 3 – Inspect coil wiring: Check the reversing valve coil connections for looseness or damage.
- Step 4 – Professional diagnosis: A technician should test coil voltage and resistance and evaluate the valve. Replacement of the valve requires refrigerant work.
