Samsung Microwave Error Code E-63

E-63 indicates a humidity sensor T1 maximum time error. The microwave's humidity sensor, which measures steam produced during cooking, failed to reach the expected signal level within the allowed time. This stops the cooking cycle and triggers the fault. It most commonly points to a blocked or dirty sensor, or an empty cavity during a sensor cook cycle.

A reset by unplugging the microwave for a few minutes may temporarily clear the error code, but it will return if the underlying cause is not addressed. If the sensor is dirty or blocked, cleaning it before restarting is the key step. A reset alone is not a fix, it is only a temporary measure.

If the fix is as simple as cleaning the sensor, there is no parts cost involved. If the humidity sensor needs to be replaced, parts alone typically range from $20 to $60, with professional labor adding $75 to $150 or more depending on your location and service provider. Control board replacement, if required, can push the total repair cost significantly higher.

Start by checking the interior of the microwave for grease, food debris, or any object that could be blocking the humidity sensor. Clean the cavity thoroughly, place food inside, and restart the unit. If the error returns after cleaning, the humidity sensor may need to be tested and potentially replaced by a technician.

The microwave will generally halt the cooking cycle when E-63 appears, so continued normal use is not possible until the issue is resolved. You should not attempt to bypass the error or force operation. Address the sensor issue first before resuming use to avoid potential damage to the appliance.
