With this model, you must remove the outer covering. Don't try to access the display unit from the front like I've seen in some other GE microwave videos. After removing the outer covering, the switches are easy to replace. They are very visible and easy to get to without taking any other parts off. You will see the door switches just behind the display board. Remove the switch and then remove the connecting wires to ensure you don't inadvertently brake a wire. You will need a tamper resistant star bit to remove 3 or 4 screws from the back panel. All other screws are philips head. I went ahead and replaced both switches (yes...there are two of them) and works like a charm. I saved an $800 microwave for less than $60 and know what to do if it happens again. Appears to be a common problem on this model. Thanks for others making a post...It saved me time and money reading others remarks. Good luck!

remov cover to check voltage and found problem at the interlock switch ohm the switch and found it was open replace both switches it work fine now

First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.

Went on Youtube and pulled up how to fix a microwave.

Checked all sensors with a multi-meter, found the thermostat to be the problem, no continuity.

Part Select sent the wrong part I did not realize it until prong broke off one of the bulbs. They sent 130v instead of 120v. Return bulbs awaiting resolution.

Our Microwave’s Halogen Light Bulb burned out.

We looked in our manual and were able to take the cover off to get to the bulb, but we were unable to unscrew the builb and the bulb in the manual did not match the size of the one you offer (size and part number were different)

We called 1-888-738-4871.

Gentleman who answered was very knowledgeable: answered all of our questions (PULL THE OLD BULB OUT) and assisted us by ordering replacement bulbs.

We (more importantly my wife) were very pleased with the result.

change bulb

Replaced the fuse. Result; did not fix the problem.

Replace the fuses

took out cover by removing cover. pulled out light bulbs replaced with new bulbs. replaced cover and tighten screw. very easy

After reading reviews that there was no power what so ever and a fuse replacement will solve the problem, I tried it. Replacing the fuse is very easy (and I am not handy at all). All you have to do is remove the microwave cover from the top by removing two screws, slide the cover to the left and pulling the cover off. Then remove the grill in front of you, by removing one or two screws. The fuse is in front of you, use pliers and be firm but gentle. Replacing the fuse is easy but it did not solve my problem.

PartSelect had helpful repair instructions on-line which made the repair easier and faster. Unfortunately, there were other problems with the oven that immediately blew the new fuse I had just installed. It was then determined that additional repair would most likely cost almost as much as a new microwave.
