MY Microvave on the cook cycle reads F4 The manufactuer says its a sensor. I found the sensor on this site and my question to you is can I replace it my self without a repair man. If so is it the service panel inside the microvave that has to be replacement.
ANSWER Hello Edward,
To replace the sensor you will need to pull unit from installation and take the cabinet off. The sensor will be on the left hand side when looking at the unit from the front.
