Unplug your microwave and turn it around and remove the screws holding cover on and then remove the cover. Look for where the power cord goes into the back of the unit and follow the black wire from the cord to where it ends. It should stop an either a circuit board or a fuse holder. Make sure that you replace the fuse with the same amperage fuse as what you take out. You will find the amp rating stamped on one of the silver collars on each end of the fuse. Good luck!
most likely you will have to remove the louvers or trim above the cooking cavity to get to the fuse, look for screws holding the trim/louvers on, if no screws are apparent, the piece may slide to the left or right and pop off.
Unplug your microwave. Although it might seem like no electrical current could possibly be running through your appliance, it could still have stored electrical current somewhere in the system. Be safe rather than sorry and unplug it before you begin.
Find the wiring diagram for your model of GE microwave. You can contact GE directly to get this if you cannot locate your owner's manual. Note the fuse locations and get a screwdriver. Some GE fuses are located under the louvers, while others are located in the door.
Open up the microwave and locate the blown fuse. Sometimes you cannot determine a blown fuse by visual inspection so check it with a multimeter for continuity across the terminals.
Replace the blown fuse. Go to your local hardware store and pick up a matching fuse. Make sure you check the model numbers of the fuse as well to be sure you get the right component. Install the new fuse and put everything back together.
Check the continuity of the circuit if you continue to have power problems. If you have a problem with continuity in the circuit, then you may have a bigger problem than just a blown fuse. Sometimes a power surge will fry a GE microwave's circuit board, which you will need to replace.
