JVM1490B General Electric Microwave - Instructions

The repair was easy, just two screws but I was very impressed with the price and swift delivery of the part from PartSelect.com. The vent grille was almost $40 less than it cost on the GE website and I had the part in 3 days. Thanks!

Watched Utube instructions on how to do it to it and just did it.

Placed the new tray into the oven.

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

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!

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

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

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

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.

I verified I had 120 volts going into transformer when the microwave was supposed to be running. The capacitor and HV diode both tested good. Be sure to discharge the capacitor before working in this area. This isolated trouble to either the transformer or magnetron. The windings of the transformer measured good. So ordered a magnetron. It was very easy to swap. There were 4 screws and one connector. This fixed our microwave.

Unplug power source.
Took off plastic panel partially on inside of door with door on its hinge.
Removed latch and spring.
Reinstalled new latch new spring (new part)
Reattached plastic panel to door.
Plug in power.

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.

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.
