JVM1490CD03 General Electric Microwave - Instructions

I replaced the TCO (fuze) through the vent opening after removing the vent cover and several small panels with a screw driver for visible access.. Some of the screws require a small offset screwdriver because of the limited access. I did not have to drop the unit from the wall over the range and was able to access through the vent opening to replace to failed TCO with a new one. The TCO is wired in-line with the power and other fuses to the unit and when it fails the enitire unit is cold with no power to lights or function of any kind. The GE service rep. said that the unit needed a new smart board but that was not the problem and they are no longer made for the older unit. I discovered the repair by looking at YouTube for repairs for the GE Advantium 120 microwave/convection combo unit.

Remove upper grill, then control panel, then 2 screws hold door switch mounting bracket, that will let you roll the switches out to work on them. Remove each switch by carefully pushing back retainer clips. Diode a long pair of needlenose pliers is helpful. The control board in front of capacitor comes out with a flat screwdriver and pry up. Removing grnd wires helps

We opened the microwave door and essentially with a straight screwdriver worked to "pop" the plastic frame off of the door. We tried to be less aggressive in our efforts and this paid off since we didn't break anything! The area we needed to work on was now exposed to put the new latch in. It took 2 hands rather than 3 to get the new latch attached and then wah-lah, It was done! Microwave works perfectly now. Great alternative to buying a new microwave!

Placed the new tray into the oven.

Unscrewed the screw, removed old cover, place new cover in place and re-inserted the scrw.

I removed the door, by taking off the grill at the top. Then, take the puddy knife and screw driver and pry the facing off of the door. Please remember to be very careful because this is a sensitive piece. This is the most difficult part. It is a piece of cake after this. This should take about 15 minutes from beginning to end.

Unscrewed the control panel (2 screws), lift up and let hang, with a plan screwdriver open bracket holding the switch, unplug 2 wires, replace with new switch, plug in the 2 wires, push switch back into bracket. Then slide on the control panel, put the 2 screws back. Easy fix.

Part just snapped into place and wires were reattached.

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

removed broken latch connected to existing spring done in less than two minutes works better than new

Opened the light cover. Removed the old light bulb using a light tug on the old bulb, lined up the new bulb and pushed gently into the socket.
Turned the power back on and the microwave is good to go.

It was really easy. I am not a handy person but I followed a video and got it done quite quickly. It saved me a lot of money. The local appliance repair service charges a minimum of $75 just for the visit plus parts.

remove with phillips screwdriver. insert 3 corners in to slots and insert and tighten screw.

Used a Motor cycle Jack to remove both unites combined. Removed side panels exposing internal working parts. Removed nonworking Magnetron and replaced it with new Magnetron. The process was completed in about 1 hour.
