Samsung Dryer Error Code hE

The hE code on a Samsung dryer means the control board has detected an invalid temperature reading from the heater thermistor. This can indicate a failed thermistor, a wiring problem in the heating circuit, or on gas models, an issue with consistent gas supply. The dryer disables the heating system when this code appears to prevent unsafe operation.

The hE code is a protective fault, meaning the dryer has already stopped heating in response to the detected problem. On gas models, it is important not to ignore the code, since an issue with gas supply or a component in the gas heating circuit should be diagnosed promptly. Continuing to run the dryer while this code is active is not recommended until the cause is identified.

Unplugging the dryer for a few minutes and restarting it may temporarily clear the hE code, but if the underlying problem is not fixed, the code will return. A reset is useful for ruling out a one-time electronic glitch, but a persistent hE error requires diagnosing the heater thermistor, wiring, gas supply, or control board before the dryer will operate reliably again.

Some causes of the hE error are DIY-friendly, such as checking that the gas supply valve is fully open, reseating loose connectors, or replacing a failed heater thermistor. Testing the thermistor with a multimeter and inspecting the wiring harness are reasonable first steps for a knowledgeable homeowner or technician. If the control board is the root cause, replacement is more complex and may be better suited to a professional.

Repair costs vary depending on the root cause. A replacement heater thermistor is generally an affordable part, with DIY costs typically ranging from $10 to $40 for the part alone. If a control board replacement is required, parts and labor costs can range from $150 to $350 or more depending on the model and service provider. Getting a diagnostic assessment before committing to a repair is always a good idea.
