JVM1429BAC02 General Electric Microwave - Instructions

Replaced High Voltage Diode. Very carfully due to the extream danger of a electrical shock.

To get to the switches you need to remove the metal cover/housing of the microwave, by first removing several screws that hold it in place, and then sliding the cover towards the back of the unit. You'll find the switches in some plastic holders above the door-open button, and it's its easy to see how the mechanism engages/disengages the switches when the door is opened and closed.

If it is not obvious which switch is bad, in our case the bad switch felt "soft" when we pressed the switch button with our fingers. A good switch has a firm "click" when pressed.

The switches are easy to replace - pop out the old switch (no tools required) and pull off the electrical connectors. Then pop in the new switch and reattach the connectors.

A great place to start is to reveiw the posting from "Marla From Arlington TX" posted on 8-3-09. It provides an excellent description of the process that you will need to follow. The only additional thing that I would add is to check the contacts on the switches. In my case I found that all three of the switches had a small build-up of corrosion. I used sandpaper to clean the contacts. Because none of the switches had a "soft" click to them, it was hard to identify the bad one. I basically picked the worse looking one and then cleaned the contacts of the other two. I'm not sure if I actually even had a bad switch or if they all just needed cleaning. Whatever the case, it worked. I would suggest checking the contacts first. You may get away with not having to replace any of the switches. And in my case what makes me think that it may have just simply been dirty contacts is that the heating mechanism would engage every now and then. It wasn't dead 100 percent of the time. It's worth a try anyway.

1. remove microwave from wall
2. remove cover (many screws)
3. remove nuts holding magnetron in place (4)
4. remove magnetron (this is a pain due to the plastic molding used to direct cooling air through the magnetron
5. get new magnetron in place (this was even more fun to find the right angles to tilt to get the magnetron to fit
6. re-tighten the 4 nuts on the magentron
7. put the cover back on
8. put the unit back on the wall.

bonus repair: the display flickered while the magnetron was on (cooking ) prior to the magnetron dying. found a ribbon cable on the control board to the display with an aluminum foil shield that had peeled off (adhesive failure). re-installing the aluminum shield with packaging tape, and the display no longer flickers

Over the range microwave. Replaced magnetron. Completely disassemble the case top and bottom.
Remove screws from bottom of HV transformer. Magnetron will not clear without this removal.

Remove nuts with socket from top of Magnetron. Remove thermo unit from old magnetron and attach it to new. Replace and bolt down Mag. Replace and screw in HV transformer. Make sure all wires are reconnected.

Put it back up on the wall. Took about three hours from taking it down from wall and putting it back up.

Remove the 2 Torx-15 screws at left of control panel. Work the control panel out by pulling slightly to the left first - it is engaged to the slotted holes to the right.

Remove the door's upper switch by lifting the tab and pulling out the switch carefully. To install the new switch, you may have to remove 2 philips screws holding the plastic assembly where the switches are mounted to the metal frame.

Diagrams on the website are misleading b/c the switch shown up on top of the other 2 switches is the switch w/ the NC (upper) terminal while you'll need the NO (lower) terminal for this repair (symptoms are: turntable won't move, no heat -but light and fan ok). I should have called before ordering the part (had to pay shipping twice)...

Once I got the right part, it works just like before.

The old fuse is perfectly good. The new ones arrived within a day.

We purchased our Microhood oven about 4 years ago along with the extended warranty package offered thru home depot. Within one year, the problems began. Each year the secondary switch would go bad rendering the microwave useless. If you have 3 small children like we do, you tend to use it a lot. We sure take the microwave for granted.

Each time G.E. would fix the problem at no charge. Ths time - the warranty had expired and GE wanted to charge us $80.00 for service call plus parts and labor. We estimated the cost to run at least $150.00 or more.

To top it all off, GE was going to have a service tech avail for over 2 weeks. This is poor customer service and completely unaccceptable.

Because this was a recurring problem, I figured it was the same part that had being going bad since we purchased the appliance. I decided to order the part "secondary switch" myself and attempt to fix the microwave on my own.

I ordered the part last Tuesday, the part arrived last Friday. Within 10 minutes I had the microwave apart, replaced the part and had the microwave back in working order.

PartSelect saved me over $100.00.

We are very satified with PartsSelect, I would recommend them to anyone

1. turned off electricity -- unplugged the unit 2. removed 3 screws on top of top vent, removed vent screen then I located the little white cylindrical fuse and popped it out with a table knife. Then I popped in the new fuse. Replaced the vent screen and screws -- plugged in the appliance and it is working again.

The microwave had been working fine until one day when the timer counted down but the heating motor (or whatever you call it) would not come on. So the timer would count down but nothing inside would get hot. I did not know what it was for sure but decided to take it apart and look. Once I had the control panal off, I found three small wired switches inside. One of these switches appeared to have shorted out. So I searched online and found Partselect.com. I found a matching switch , ordered it (arrived in couple days), put it in, and VOILA it works! Thanks Partselect.com.

I've been fixing and taking things apart since I was a kid. I hoped that it was a bad switch in the door. Got out my test meter and check the 3 different switches. All 3 tested good, but one was a bit hit and miss. It would work if the microwave was on its side and wouldn't when it was set flat. I found the switch online and installed it. Took care of the problem.It was a whole lot cheaper than buying a new microwave. Thanks! Bill Brown, Fridley, MN

This was a super easy repair job. I couldn't figure out how the lens that covered the light bulb would have cracked and realized it must have been from my contractor when he replaced my stove. I can't prove it, of course, so I am left doing the repairs. The website was very easy to order from and confirm that I had the correct parts as the model numbers tend to change over time.

This did not fix my problem. I've ordered a new microwave.

First off, UNPLUG THE MICROWAVE.

The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the microwave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.

This repair could not have been easier! The website was great at helping to identify the problem and the part needed. Users discribing how they did the repair gave me the confidence to do it myself. I got the part the day after I ordered it, installed it and my microwave was a good as new! It was as simple as unscrewing seven screws to remove the bottom of the microwave. Then two more screws to remove the part. Unplug the broken drive, plug in the new one and screw everything back together! Don't forget to unplug your microwave before you begin.

Great website!

Loosen screw holding glass cover plate in place over bulb. Glass cover plate will swing down. Unscrew bad bulb, replace with good bulb, reset glass cover and tighten screw.
