Samsung Dryer Error Code EH

The EH code on a Samsung dryer indicates a heating error that occurs only during Heating Test Mode. The control board triggers this code when the thermistor detects a temperature rise of less than 2°C within one minute of the heater activating. It signals a problem with the heating element, the heater circuit, or the thermistor itself. A technician should inspect all three areas to identify the root cause.

The EH code only appears in Heating Test Mode, so your dryer may still run in a normal cycle. However, if the underlying heating fault is present, your dryer likely will not heat properly during regular use, meaning clothes will not dry. Continuing to run the dryer without addressing the fault is not recommended, as wiring or component issues left unresolved can worsen over time.

Repair costs depend on which component has failed. A thermal fuse is typically an inexpensive part, with the repair often running between $75 and $150 including labor. A heating element replacement generally costs more, commonly in the range of $150 to $300 depending on the service provider and part cost. A thermistor is usually on the lower end of the parts cost spectrum, though labor rates in your area will affect the total.

Some causes of the EH code, such as a loose wiring connection, can be addressed by a knowledgeable DIYer who is comfortable working with appliance electrical components. However, replacing a heating element, thermal fuse, or thermistor requires basic electrical testing skills and the correct replacement parts. If you are not confident working around high-voltage components, it is safer to call a qualified appliance technician.

Resetting the dryer by unplugging it for a few minutes may temporarily clear the code from the display, but it will not fix the underlying problem. Because EH is triggered by a specific performance test result rather than a one-time sensor glitch, the code will return when the Heating Test Mode is run again if the root cause has not been repaired.
