Heat pump Samsung dryer displays HC4; the unit may stop and show an overheating warning.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Clogged condenser filter, Blocked airflow around the heat pump unit, Faulty condenser fan, Defective temperature sensor on the condenser

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 as 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 the fins.
Check fan operation: With panels reinstalled, briefly power on the unit 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.
