Samsung Hood Error Code E-25

E-25 on a Samsung hood indicates that an abnormal temperature was detected during Micro Cook mode. The appliance monitors internal temperature through a thermal sensor or thermistor while the microwave cooking function is active, and this code appears when the reading falls outside the acceptable range. The unit stops the cooking cycle automatically to prevent potential damage to the magnetron or other internal components.

You should not continue using the Micro Cook function while the E-25 error is active. The code indicates a temperature problem that, if caused by genuine overheating, could damage the magnetron or create a safety hazard with continued use. The ventilation fan functions of the hood may still be usable, but the microwave cooking feature should remain off until the fault is diagnosed and corrected.

A power reset, done by unplugging the unit or switching off its circuit breaker for a few minutes, may temporarily clear the E-25 display. However, if an underlying fault exists in the thermal sensor, thermal cutout, or cooling fan, the error will return when Micro Cook mode is used again. A reset is a useful first step to determine whether the fault is intermittent, but it does not fix a hardware problem.

Some steps are DIY-friendly, such as cleaning clogged grease filters and checking that ventilation openings are clear. However, testing and replacing components like the thermistor, thermal cutout, or cooling fan involves working near high-voltage microwave circuitry, which carries serious safety risks. If you are not experienced with appliance repair and high-voltage systems, professional service is the safer choice.

Repair costs vary depending on which component has failed. Replacing a thermistor or thermal cutout is generally a lower-cost repair, often ranging from around $75 to $200 including labor. A cooling fan motor replacement may cost somewhat more, and a control board replacement typically falls in the higher range of $150 to $400 or above. Getting a diagnostic estimate from a qualified technician before committing to parts is a practical approach.
