CVM1790SS4SS General Electric Microwave - Instructions

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!

When removing a non-working door switch, you will see a hooked piece of plastic on the holder locker that looks like a latch. If you try to pull it back in order to either remove the bad switch or install a good one, it will likely break. Instead, you need to pivot the switch (It pivots on a little post which is fitted into a hole at the corner of the switch) out of position so that it is not held back by the 'latch'. Then lift the switch out. If you have to use lots of force anything, you're doing something wrong. Reverse all this when installing the new switch.

Disassembly control panel and remove switch holder; test for micro switches for continuity. Holder had broken post on micro switch holder.

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

I did some research and found the part through this website. Very easy to change the heater sheath, just took long to take everything apart. Looked at some diagrams to see exactly where the part was.

The Halogen Light Bulbs for lighting the area below the microwave seemed to be burned out. I order new bulbs but by the time they arrived the old bulbs appeared to be working again. Not sure why this happened but I have new bulbs if they become burned out for good at some point.

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.

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

Ridiculously easy, unscrew, and change bulbs. Having the correct bulbs made all the difference, I did not have to waste time looking for the correct one.

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.

Replace the fuses

change bulb

Inside "cavity" bulb was a PITA. Need to remove top decorative trim (2 screws and tabs) to access bulb housing. Broke 1 screw tab so be careful (Wiggle it more). Acccess to bulb housing was made for younger smaller hands, attached by 1 screw. Remove screw, rotate housing, replace bulb. Reverse proceedure. Outside bulb, cake...1 screw, drop lens replace bulb, your done.

Removed the glass shield and inserted the 2 bulbs. Then replaced the glass shield.

The staff were terrific. Thanks so much as it had a happy ending.

Removed screw holding faceplate that covered bulbs. Next inserted new bulbs into sockets.
Turned on surface light to insure they worked - they did. Re-attached faceplate.
