JVM1740SP1SS General Electric Microwave - Instructions

Turn off main power bracker. Removed fan vent, removed control panel, disconnect leads to the three monitor switches. Replaced the secondary switch (top). Reversed procedures.

Removed 5 screws from the bottom of the over the range microwave to expose the light sockets. Removed the 1 screw holding the socket, disconnected the wires. Attached the wires to the new socket, Put in the bulb, reattached it with the screw. Repeated on the other light... It took about 20 minutes and now the lights work just like they should :)

Removed the microwave with the buit in housing from the cabinet. Removed microwave from built in housing. Removed outer cabinet giving access to remove control panel and smart board where switches are located. Removed control panel to get to smartboard. Removed smart board after disconnecting a few wires to allow easy removal. Individually removed and then tested each switch using multimeter. Found seondary Door Switch (bottom of smart board) operation to be intermittent (switch trip button extremely loose and rattle inside this particular switch) Ordered replacement part which came very quickly on standard shipping order. Put new switch on smart board and remounted, reinstalled control panel and reconnected various wire connectors previously disconnected. Then plugged in oven and tested for opertation - didn't work at all! But, after bleeding off capacior charge by removing connectors and discharging capacitor to ground, then reassembling control board and smart board into oven, then trying agian, it has worked perfectly ever since. Do not understand why capacitor disconnect/discharge was required but suspect this reset the control electronics. Easy fix and hope to get another 12 years out of this appliance which is used multiple times every day. Also have two other identical micorwave ovens, one is 20 years old, but these get used relatively infrequently.

Loosen the two long anchor bolts that screw into the top of the microwave cabinet. These are usually in a shelf or cabinet directly above the microwave. Tilt the microwave forward enough to remove the 2 Phillips head screws from the top of the microwave cabinet. They are near the front. When these two screws are out, remove the fan vent. Once the fan vent is off, remove one screw that holds the control pad in place. Let it hang down. Just to the left of the control pad, you will see wires leading to three switches that close when the door is closed. Use a torx driver to remove the two screws that hold the switch bracket in place. With the bracket out, unplug the wire harnesses. On the opposite side of the wiring connected, a tab holds each switch in place. Lift the tab and slide the switches out. Usually, the bad switch will be identified by a loose or broken spring. Test them by pressing down on the switch. If you notice the bad switch spring, this is usually the bad one. When you have the new one, simply push it back into the appropriate slot and be sure that the holding tab snaps back in place. Plug the wires back in and re-attach the bracket. Put the control pad back on, then the fan vent. When down with those, push on the bottom of the microwave to lift it back into place and tighten the two anchor bolts in the top.

Remove the microwave cover. Requires a phillips screwdriver and a torx security bit/nut driver (there are two security type screws on the back...guess they don't want you to do this at home!). I had to buy the a security bit set (about $7). The diode is easily accessible on the right side under the fan. Requires removing on small phillips screw and unplugging on electrical connection. GE provides some instructions in an envelope on top (after cover removed). There is a warning/instruction to discharge the capacitor before service. This was not a problem for me. Actual diode replacement took 30 seconds. Whole job = 15 minutes.

Changing 2 lightbulbs is NOT ROCKRT SCIENCE. With a screw-driver, remove the under MW light lens, unscrew the 2 burned out light bulbs, and replace with 2 new quality light bulbs. Test out that both are lite and working as they should, replace the lens and you are done, Until you find out one of the new (made in Chins) light bulbs is burned out after about 6 hours of being lite, call the parts phonr number and order a new replace bulb.

The order was easy and promptly received. I lowered the cover by removing retainer screws underneath. Simply lowered it and removed the broken glass and replaced it. The bulb was broken and the base of it was stuck in the socket. I didn't bother to remove it because the socket was brittle. I disconnected the socket by unplugging the wires, removing the retainer screws,and removing it. I replaced it with the new one. Screwed in the bulb. I replaced the cover and it was done. Ps: I used an Hitachi cordless screwdriver, which greatly helped when doing this alone.

As suggested, I placed a towel over the stove. Only had 3 main screws to remove from bottom of microwave. Dropped the bottom and changed the sockets and light bulbs. After replacing the bottom tray, I put the new glass light lens in. The clips on glass holder bent back like a photo frame-really easy. Turned on the lights and was done.

Very easy to replace the light socket. Unscrew screws under microwave to lower the base. remove screw at rear of light socket. Unplug power to socket. Plug wire into new socket. Replace new socket into base and replace serew. Hold base plate up to microwave and replace all screws. Do yourself a favor, if replacing one of the lights, go ahead and do both. Shipping cost is the same for 1 or 2 bulb sockets.

Watched How to repair a Microwave that turns on when the door is opened Video on the web. From this took a shot at the switch was the problem. When I removed the switch it was defective. The small button was in and when you turned the switch upside down the button would drop back into position. Ordered a switch for $25.oo , installed it and the microwave is working fine.

Unplug appliance, Staring from the rear sides, remove the four side screws. Remove the left and right front screws and finally the front center screw. The bottom panel hinges down toward the rear . Unplug the input wires from the sockets . Unscrew the two retainer screws (one each) and pull the sockets out of the panel. Note that the retainer screws are shouldered. The shoulder fits through the elongated slot in the socket. Screw the bulb into the socket and insert through the mounting hole. Insert and tighten the mounting screws. Note that the sockets may appear to be a bit loose. That's OK because of the shouldered screw. Don't over tighten or you risk stripping the threads of the panel. Plug in the input sockets and install the panel screws in the reverse order of removal. Plug the appliance in and test the bulbs.

Opened the microwave oven door, unscrewed two screws which held the control panel on, then I removed two of the door switches (each had two screws), and then used the continuity tester to see which one was not operating. It turned out to be the secondary door switch, replaced it and to my amazement, the microwave worked. I have never repaired an appliance before but I didn't want to replace our over-the-stove built in microwave. It was the best day ever when it was working again! The hardest part was getting myself to try the repair.

I tried to replace a light bulb over the cook stove without turning off the power supply. The light socket had deteriorated and the bulb base shorted out on the microwave frame. I ordered new sockets and bulbs. Replacing them was s simple matter with the power off. However, there was still no lights working with the power on. I pulled to cover off on top of the microwave (two screws) and checked the fuse. Continuity test showed it to be ok. Next I pulled the cover off the control panel and pulled out the mother board. On the back side I noticed two burnt pins. I applied solder with a solder gun to replace the burnt off solder. I put it all back together and it works fine.

I thought I could just unscrew the bulbs in the SpacemakerXL Microwave Oven. The bulbs melted into the bulb socket so every attempt to unscrew the bulb with pliers just broke the socket. So I took out the few screws holding up the bottom panel(with the bulbs and filters). I unplugged the electrical connection and took out the sockets but I used PAM Cooking oil on the electrical connections plugging into the sockets to avoid pulling the wire holders from the connection. Replacing both bulbs and the sockets at the same time makes sense since the heat from the stove melts the bulbs in the socket.

Microwave would not turn on. Lights and fan worked fine. Before the microwave stopped completely, it would turn the microware fan on even when door was open. I read the reviews and they were exactly the same issue that others were facing. Once I opened the front panel and got to the switches it was easy to figure out which switch was bad as it was the one that was soft (When clicking it). It was hard to take it out though (it seemed stuck). So, I used a plier to yank it out. I put in the new switch and everything worked just great! I would like to thank other comments that were left on the site to make my task much easier. Thank you (to the commenters on PartsSelect), you not only saved me money, but also ensured that I learn about the microwave more and give me the confidence that I could fix it.
