Samsung Dryer Error Code HC5

HC5 means the dryer's compressor has stopped due to high temperature three accumulated times, as detected by Thermistor 5. This is a protective fault specific to Samsung heat pump dryers. The dryer shuts down completely after the third compressor stoppage to prevent damage to the refrigerant system.

No, you should not continue operating the dryer while HC5 is active. The code indicates the compressor has already overheated and shut down three times, and running the appliance further risks permanent compressor damage or other component failures. Address the underlying cause before resuming use.

Repair costs vary widely depending on the cause. Cleaning filters or adjusting installation clearance costs nothing beyond your time. Replacing Thermistor 5 is a relatively minor repair, typically in the range of $75 to $200 including labor. Compressor replacement is significantly more expensive, often ranging from $300 to $600 or more, and may make repair less economical depending on the age of the unit.

Some causes of HC5 are DIY-friendly, such as cleaning clogged condenser and evaporator filters or ensuring the dryer has adequate ventilation clearance around it. However, if the compressor itself is faulty or a refrigerant issue is involved, those repairs require a certified technician with the proper tools and refrigerant handling credentials.

A power reset may temporarily clear the displayed code, but if the underlying cause is not resolved, the compressor will overheat again and the fault will return. The HC5 code tracks accumulated compressor stops, so the root cause must be identified and corrected to prevent the fault from reoccurring.
