JVM1640CJ - Instructions

Removed screws holding outer shell. Pushed in door handle to identify faulty switch. Ordered part. Pryed switch out with screw driver and unplugged. reinstalled new switch. Presto. BUT... I did NOT use both hands while working on the microwave. I did not release the energy from the capacitor or whatever holds the killer amperage even when unplugged. It would be advisable to do this first. I did not because it seemed complicated, so I was EXTREMELY CAREFUL about not touching anything else inside the unit. I used one hand only so if I did touch something I would not get juiced through the chest. It was a piece of cake repair, but I would not go deeper without doing the discharge routine.

This is a over-range microwave. Due to heat the door panel and the guides which keep the inner glass just broke/ disintegrated. The steps to repair were as follows:
1. Remove the existing door from the microwave
2. Remove the outer glass door.
3. Carefully remove the inner door assembly and the choke cover.
4. Fit the outer glass in the panel
5. Add the Latch, fit the main door assembly
6. Add the inner choke.
7. Fit the microwave door in place again

1 was really simple. Needed to remove the vent grill at the top before removing the door. The screws were at the top. Please be careful with the tabs on the grill at the bottom of the grill.
2. The glass was simple to remove as the panel was broken.
3. Removed the inner choke and latch before the main door assmbly could be removed. Used a butter knife to remove the inner choke. One advice is not to pull at any of the assembly. Just work at it in circles. It gets easier as more and more tabs get free. In short patience and light force.
4. Fitting the glass on new panel was the difficult part of the project. There is no way to slide the glass in all the notches. You have to kind of pull the trim to fit all around the glass (it is a bit elastic). Be careful with the force you use. Keeping going at it in circles. Everything does not need to be in its final position in the first go. The glass was sticking out in the notch where the latch goes. I pulled at the trim and pressed with light force all around till the glass went in completely.
After this it was a piece of cake. Forgot to screw in the latch so had to take the inner choke off again. Luckily I had not pushed it all the way in.
At the end I felt there was a slight bulge along the door top. I thought I needed to press the trim to fit in more with the glass. Nobody else saw it so maybe I was imagining it.
Great site. The experiences helped in giving confidence. DIY brought down the repair cost by 1/3rd; just $50 and good experience which makes it priceless.

just slipped the filter in place.

unplugged power cable / unhooked front vent / unscrew the monitor panel / slide up to dislodge / take the fuse out and put in the new one in / fuse is located right in front of monitor panel once its open might be covered by wirings / you can unpin the cables from the panel to make it easier for you just make sure to put it back properly or you can have somebody hold the panel for you. Installing the fuse is easy waiting for the parts is crazy......

I wasn't sure which parts I needed.We searched several web sites until we found yours.I was real pleased with the service. My parts where delivered in a timely manner. Everything I needed to install my microwave was in my order. Thank you for the service.

Had to remove outer cover (special screws involved). Found the correct part at PartSelect.Com and it arrived 3 days later as promissed.

This oven has diffcult electrical connections at switch to get disconnected. I found it easier with the sw loose and in hand so that the connectors can be released with a small screwdriver.

One has to this in order to test the part wirh an ohm meter. I found the sw did not close but remained open and thus caused the oven not to function.

Removing interconnect switch is tricky but not difficult.

Outer cover replacement is not as easy as it should be, especially the sides.

All is well and working.

Microwaves are simple devices if you are know how to read and understand schemetic diagrams.

I just needed to remove 2 philp screws and insert filter. The filter fit perfectly and perfomred as expected.

Watched a couple of repair videos on Youtube by searching for the model number. Found out what to do in order not to get shocked by the powerful capacitor.
Ordered the two switches (To be sure, I could have ordered a third switch as suggested in the videos.)
Bought a tamper-proof star bit to get the cover off. Followed the directions to replace the switches. - I broke the harness and had to use some super glue, but it's all good. I should have removed the harness instead of trying to get a switch out while it was still in place.
It's all back together, and the wife is happy!!

1) Removed 4 screws securing the microwave to the cabinet.2) Slid microwave out, unplugged and placed on a work surface that allowed lower trim to hang over. 3a) Removed two screws and removed the cover on top of the oven. 3b) Unplugged high voltage plug from Magnatron. 4) Removed wires from overtemp fuse mounted to Magnatron. 5) Removed the four screws securing the Magnatron to the oven. 6) Removed Manatron. It's a tight fit, but can be done without removing anything else. 7) Replaced Magnatron. This is where I needed the magnetic part retrieval tool. The nature of a Magnatron is the use of strong magnets surrounding the tube. Getting the four screws back into place wasn't possible with just a normal magnetic screwdriver tip. I used the retrieval tool to position the screws back in place. Be sure to not initially tighten any screw completely, until they can be evenly tightened. This ensures correct compression/seating of the shielding material near the neck of the tube. 8) Reverse removal steps. Plugged in and tested microwave function on a cup of tap water. 9) Reinstated in cabinet and got a big thank you kiss from the wife!

One small Phillips screwdriver and one fuse puller (I used cord). Unplug unit. Remove the two screws on the vent face plate. Remove the one screw on the panel assembly. Gently let hang. Pull the fuse located on the upper left wall. Replace fuse. Reassemble.

First remove all screws holding on outer metal casing of microwave. Next remove the back and bottom metal pieces. You will then be able to pull aside the outer casing so you can access the door switches. Check each switch with an ohm meter in both the open position and with the switch closed. If the ohm meter reads the same in both the open and closed position, the switch is bad. Check the top switch first. Replace switch and reassemble. Cheap fix for a costly microwave. Great customer service at Parts Select!

removed two screws, set in place. done. The best parts was that your ordering and shipping was out of this world. Never thought I would get the Filter that fast. Thanks You made my day.

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.

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
