JVM1540MP1SA General Electric Microwave - Instructions

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.

Because the microwave is old and the bulbs, I believe, had never been changed I carefully tried to unscrew the bulb. However, when I went to unscrew the bulbs the end of the bulb broke off and remained in the socket. I used a few different tools then remembered that sometimes a raw potatoe can be used to unscrew the remainder of the bulb, but to no avail. Finally had to unscrew the whole underside of the microwave to remove the broken bulb. May I suggest that you have the socket face away from the wall to screw in the bulb instead of the socket pointing toward the wall. You need to know yoga just to manuver the bulb into the socket.

First, unplug microwave. Unscrew two screws at top of microwave, slide grill cover left and remove. This allows access to single screw holding control panel. Remove this screw and lift up control panel to remove. Secondary door switch is black switch at lowest position. The switch is held in place by a lever in back and very hard to get to. Remove the wires plugged into the switch, then remove two screws holding the plastic switch mount that holds all three switches. These screws use a "star" type screwdriver. Once the plastic mount is free, lift it up, right, and tip it slightly to find the lever that will release the black secondary door switch (the lowest switch)...release the broken switch, snap the new switch in its place. Replace the plastic mount by lifting and replacing back into position and replace the two "star" screws. Now, replace the wires onto the new switch, and test operation. Replace control panel, and top grill. It goes faster than it writes...getting the old switch out through that difficult to reach lever was the hardest part...still less than thirty minutes.

every thing is working, but no hot

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.

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.

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.

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.

removed the front panel as per instructions from microwave book. found where the filter went ,slid it in the space put the panel back on. Done 3 screws. I'm a 73 yr. woman and if I can do it anyone can.

Using a #2 Phillips screwdriver and removed the screw that retains the lens frame around the broken lens. I also did the same to the opposite side (whose lens was fine but the bulb had been burned out for some time). With my fingers I pryed up the frame clips that secure the lens in place, removed the pieces of the broken lens, and replace the lens with one of the new lenses I had ordered. Although the bulb on this side was still burning, I replaced it with one of the two I ordered anyway. When I removed the bulb that was burned out, the glass separated from the bulb's base. However, I simply put on a set of tight fitting leather gloves and used my ring finger to apply pressure inside the base and it soon began to twist and then came out. This takes a little manual dexterity, but is very doable. If it were too tight, you could take a large "easy-out" tool (like the one to fit a 3/8" - 1/2" hole) and it would remove the broken base in short order. I had also ordered a second lens, but the lens on the burned side was simply dirty, so I cleaned it, put it back in place and saved the new one for a rainy day. By the way, BE ABSOLUTELY CERTAIN THE LIGHTS ARE SWITCHED TO THE "OFF" POSITION BEFORE DOING ANY OF THE ABOVE. Also take care to clean the glass on the bulbs with denatured alcohol and handle them with clean cloth gloves or a tissue so as not to allow any oils to be on the surface when they are switched on. Body oil will immediately create a hot spot which will shorten the life of the bulb by at least 50% if not more.

Simply unscrew the bottom panel of the microwave device (it swings downward when opening - there are hinges on the back to protect it from falling down). Remove the old light socket (which is modular and is screwed in place)from the connectors and then replace it with the new light socket. That's it

Very simple disconnect light socket unit from snap in power supply replace socket with bulb screwed in reattach & back in business. Your service in supplying needed parts was par excellence. Thanks again

replaced the glass

easily replaced. parts arrived quicker than suggested. thanks
