Samsung Microwave Error Code E-25

E-25 means the microwave detected an internal cavity temperature above 200 degrees Fahrenheit at the start of a cook cycle. This is a safety protection feature that prevents the oven from operating while overheated. The error can be caused by genuine overheating from recent use or by a faulty temperature sensor reporting incorrect values. Pressing Cancel and allowing the unit to cool down is the recommended first step.

No, you should not attempt to force the microwave to operate while displaying E-25. The error is an active safety protection indicating the unit is too hot to run safely or that a sensor fault is present. Continuing to operate it in either condition could cause component damage or a fire risk. Allow it to cool and reassess before using it again.

If the fix is simply allowing the unit to cool down, there is no cost involved. Replacing an internal temperature sensor typically costs between 15 and 60 dollars for the part, plus labor if a technician is hired. A control board replacement is significantly more expensive, generally ranging from 80 to 200 dollars or more for the part alone, and may approach or exceed the value of an older unit.

Pressing the Cancel key and allowing the oven to cool down for 20 to 30 minutes will clear E-25 if the cause is genuine residual heat from a previous cook cycle. If the error returns immediately after a full cool-down, the fault is likely a defective temperature sensor or wiring issue and a reset alone will not resolve it. In that case, component-level diagnosis is required.

Start by pressing Cancel and letting the microwave cool in a well-ventilated area for at least 20 to 30 minutes, then attempt to restart. If the error clears and does not return, overheating from prior use was the likely cause. If E-25 comes back after cooling, the internal temperature sensor or its wiring harness should be inspected and tested, and the sensor replaced if it is reading out of range. A control board fault is also possible if the sensor checks out correctly.
