JVM1490B 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.

Placed the new tray into the oven.

Another company said the new plate would arrive in mid-March, this company seemed to be faster so ordered the tray here, and it came in less than a week. I put the turn button back in the center hole, set the wheeled ring on the bottom of the oven, fitted the new glass tray onto the turn button.

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!

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

two screws out two screws in done in seconds

We used the scresdriver(flat) to remove the frame inside the door, the remove several screws retaining the inner part of the door thenremoved the broken piece. We replaced the latch with the spring With a little patience, everything went fine. I broke one of the small tab, no big deal.
thanks, you saved me a lot of money/.

This is a simple task. Removed the choke cover using a putty knife or small flat screw driver. Putty knife works best. Slide putty knife under the plastic choke cover to lift up over clips all around the door. There are 3 on top and Bottom and 2 on each side. Be very careful or you will break the catch clips that hold the choke cover in place. Lift the door latch up all the way and push towards the outside of the door, then pull the top or bottom out then the rest of it. Unhook the spring end from the door. Attach the new spring to the hook on the door and then to the door latch. Extend it up all the way so the 2 hook parts of the door latch can go back into their slots. Unlike some others said, the microwave door does not need to be removed. If you have someone to hold the door still, that's good enough. I did it by myself with no problem.

I first read where someone had the same problem. Their solution was a burned-out fuse. I ordered a new fuse...installed it and that did not solve my problem. I revisted PartSelect and read how Marla (from Arlington, TX)solved her problem. I purchased a secondary switch and when it arrived, I made a copy of Marla's instructions and followed them to the letter. I installed the new secondary switch into the secondary space, put everything back together and the oven STILL DID NOT WORK. I had to take the latching panel apart again and test each switch to see if there was another bad one. I found that the third switch was burned out. So I took the new switch out of the second slot and installed it into the third slot. I tested the switches before reinstalling the latching panel. This time everything worked. So I put everything back together, reinstalled the microwave on the wall, tested it again, and everything worked perfectly.

I want to preface this review by stating that I do some DIY from YouTube, but have no experience in electronic repair. The microwave is over the stove with the extendavent. First I unplugged the microwave, removed the vent and started to unscrew the microwave from the mount. I used a power drill to speed things up. I was able to remove the microwave on my own. I unscrewed the lid on the microwave and took the lid off and there is the magnetron. I opened up needle nose pliers to have each end touch the terminals of the capacitor (holds the power, Dangerous). I made sure to keep my hands on the rubber handles and avoid touching the metal part of the pliers. I used the pliers to remove the plug of the capacitor to the magnetron as well. The magnetron has 4 screws (2 top, 2 bottom). There is a magnet that can hold the screws to keep from falling but I’d still recommend a screwdriver with a magnet on the end. The magnetron has another set of wires connected by a metal bracket like a holder, not really connecting any wiring to the magnetron itself. I had to unscrew 1 screw to removed that. Adding everything back on was easy, same steps back. I plugged in the microwave and tested a cup of water before I mounted it back above the stove. Voila! I did need my wife’s help to hold the microwave on the hinge while screwing into the mount. It doesn’t take a lot of muscle for the help. $85 for the part and ~40 mins to fix a $400 microwave!
