JVM1640WJ - Instructions

Just pulled off the cover, removed the old latch, re-connected the spring...put it all back togeather. Everything just snapps back in. The entire repair took about two minutes. Very easy.

Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover.
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.

Unscrewed the vent at top of microwave exposing small access to bulb. The access to this was very limited so that was the major issue in changing the bulb. You needed small hands to do the job.

Symptom: Terrible sparking coming from the right side of the microwave even with nothing in the microwave. The part that was behind the cover was the business end of what I learned was the magnetron,

Repair process: Without appliance repair experience I went onto Google and searched for parts for my model PEB1590DM2WW. I was able to find a great parts schematic on partselect.com. At first I ordered a magnetron and while waiting for the parts to arrive I also learned that the capacitor can also fail easily as described in the other install feedback on the partsselect website. So I ordered a capacitor just in case. These convection microwaves are around $600 new so a $80 in parts is not out of line for 8 years of service.
I installed the magnetron first and turned it on. sparking immediately continued so I quickly shut the unit off. After replacing the capacitor and letting it charge for several minutes before trying to start the microwave cycle was the issue. I choose to leave the replaced magnetron as the original unit was discolored and felt the replacement was inexpensive insurance. I also learned that if the wave guide (which is a plastic/metallic composite material) that covers the opening to the magnetron is burnt or has metal melted to it as mine did it will act similar to the microwave having metal inside the enclosure and will continue to spark and basically melt the wave guide further. Replacing the wave guide was very easy as well.

I am very thankful for the knowledge base and support available from Partselect.com as they made this repair possible on my own. Thank you partselect.com

Looked on line and found a you tube that said to check the door micro switches (there are three of them. Found one of the switches had an actuator that was stuck down. I got the actuator working but problem was still present. Another you tube showed how to repair the contacts in the switch and that solved the problem. however the plastic piece that holds the switches was broken and would not hold the switches securely. Ordered that piece and a new switch. Remove the vent plate on top (one phillips) and the control panel (one phillips). The switch holder is held in place with 2 phillips and is a little tricky to get it out and undo the wires. Once out, it's just a matter of putting the switches into the new holder and reinstalling it. Google the model number and the problem and there's virtually a you tube to repair ANYTHING.

Moved the stove from underneath the microwave. Took the microwave down and turned it over. this need not be done. took the screws out to remove the bottom panel. there is a quick disconnect that need to be opened up. used pliers to remove the bad sockets and installed new one, used pliers to seat them. put bottom panel on, hooked up the quick connect. put the screws in and tightened them. installed bulbs and hooked up the electric and turned the lights on, they worked. installed the microwave, slid the stove back in place.

Open microwave door and remove plastic cover running across top of the oven box by unscrewing 3 Phillips head screws above and behind plastic cover. (4th screw to the right is not related to this cover). DO NOT PULL COVER STRAIGHT OUT. Cover slides either right or left then pops out. Remove old filter and replace and reinstall cover. Filter lays at a 45 degree angle against metal tabs tilting toward you.

Just placed it in microwave

Everything worked on the display light inside worked but when you closed the door and set time it would start counting down but not heating nor would the turntable turn. Started reading troubleshooting chart and first thing I did was removed the cover and checked door switches and found primary door switch wasn't working so I ordered a new one installed it and it worked. Anyone doing this has to be very careful because of the stored energy in the capacitor is strong enough to kill.
My micro is only 2 years old so I was hoping it wasn't anything major.

Lifted the door off of the pins. slipped the new door in.

Removed turn table,removed old ring,put new one in its place, Put turntable back in and ready to go.

Took off plastic around inside the door , took broken latch off and put spring on new latch on plactic on and it works . ????

I was surprised to find that the turntable for my 10 year old GE Profile microwave/convection oven was not readily available at my local GE retailer. I ordered the part from this website hoping that my order would be filled. I received an immediate response from customer service and the part was on my front doorstep in under 1 week! I would order from this website again!

I removed the main cover ( torx security bit required) and tested the magnetron, capacitor, diode and door interlock switches according to instructions found on the internet. The capacitor and diode tested good but the magnetron looked burnt and corroded on the tip. The magnetron I received was an exact replacement for the original. It was easy to replace the magnetron which arrived in 2 days standard shipping. I also cleaned the fan while I had access to the inside area. Hoping to get another 18 years use from the microwave!

I just matched the prong in the turntable hole and coupler fit into the hole perfectly. All The Best.
