How to Fix / Troubleshooting
Safety: Unplug the dryer. Heat pump components can be hot and under high voltage.
- Clean filters: Remove and thoroughly clean all lint filters and any additional heat pump/condenser filters per the user manual.
- Clean condenser: Access the condenser unit (often via a lower front panel) and gently vacuum dust and lint from the fins. Do not bend fins.
- Check fan operation: With panels reinstalled, briefly power on and listen for the condenser fan. If the fan does not run, the condenser fan motor may be faulty.
- Service required: If cleaning and fan checks do not resolve HC4, a technician should inspect the heat pump system and sensors.
