How to Fix / Troubleshooting
Safety: Turn off power before opening panels.
- 1. Check outdoor unit operation: Confirm if the compressor is running (distinct humming and vibration) or only the fan is running.
- 2. For heat pumps: Switch thermostat from COOL to HEAT and back, listening for the reversing valve shift. If no change, the valve or solenoid may be stuck.
- 3. Inspect capacitor and contactor: Look for obvious damage and replace if bulged or burned.
- 4. Professional service: A technician should check refrigerant pressures, compressor operation, and reversing valve function.
