JVM1740DM1BB General Electric Microwave - Instructions

The switches are not the problem! The problem is in the tolerences of the latch housing. I have ordered two new housings (Upper & Lower) and will see if the tolerences are closer. If not I will try epoxying a shim to the plate that operates the microswitches. The other option is to file the mounting slots of the housing to allow adjustment, which would be iffy,keeping them from moving with use. The exploded drawings really need to be clarified. The scale is way too small. It was extremely difficult to pick out the individual parts of the mechanisiam.

This particular microwave is the over the range type, with an exhaust fan at the top and charcoal filters over the stove. Then to the side is the control panel for the microwave oven. You have to get into this to get to the fan. To do this, you have to take off the vent trim at the top of the microwave. Two screws. Open the front door and gently wiggle once the screws are out. Care must be taken with this because over time the channels that the screws go in can break, and then once that happens there's nothing to hold the vent into the oven. (I've replaced this once when both screw openings simply crumbled). Once it's off, there is a screw under it at the top of the control panel that needs to come out. There's another screw at the bottom of the control panel. Then, you slide the panel up about a half inch and then you can pull it out. After that, you can see the fan in there. There are two screws holding it in and a bunch of wires all around it. Pull out the multipin connector on the fan. There is a second plug-in wire that you may need to use pliers to get a grip on it. Pulling out a couple other nearby wire connectors will help loosen it all up so that you can move the wiring harness out of the way and tilt the fan out and remove it. Looking at the old fan, the bearings were tight and worn out, and that was the problem. It's not a particularly well made fan. Very simple open-frame motor with moving parts exposed, so it probably through the years ingested oil vapor from cooking, etc. Tilt the new fan into position, put the two screws back in and re-insert the wire connectors. Then all you need to do once all the wiring is neatly dressed again is put the panel back on, the two screws top and bottom, and lastly reinstalling the long vent at the top, (two long screws). Do that, and you're done. The microwave sounds fine now and works great.

Turntable coupler broke due to plastic wrap getting tangled, top part came out easy, other piece that broke did not come out so easy. Placed used stocking over shop vac end and vacuumed out broken piece, replaced with new coupler. Done.

Pulled micro off the wall, took side/top cover off to get at the cooling fan behind the control panel. Unplugged wires and removed control panel to ease the removal of the cooling fan. Two screws hold the fan. Pretty easy job.

I initally thought the problem was the turn table motor but after installing that motor & not being successful I realized the problem was the stirrer motor.Removing & insalling that motor was a bit more challenging but worth the effort as I saved either the cost of a repair technician or the puchase of a new one.The microwave is back in service & running fine.

All electrical worked (fan, lights, control panel) door switch was broke. Pulled the oven out. Took out two big screws from the cabinet above. (be careful not to drop oven)Set the oven on kitchen counter. Took off five screws that held the vent cover. Removed vent cover. Took out one screw that held the control panel. Lifted, turned and slid the panel into the space below so I could get to the upper door switch. Replace door switch and re-assemble.

Rather than open access door took off bottom (5 screws) This gave more room as the microwave is mounted under the wall cabinets over the stove.

I unscrewed the entire undersurface of the microwave (I didn't do this before!) and replaced the light socket. Easy job and I'm glad the part was still available.

Removed the 7 screws holding the bottom of the microwave cover, also opened the access covers to the lights. Damaged socket was easily replaced along with both bulbs and the broken lens, then resecured the covers. Top front cover was removed (2 screws) and the new filter was inserted, then the cover replaced. Very easy, about 15 minutes, without any injuries!

Had trouble isolating the problem, so I had a repairman identify the problem, then I ordered the part and replaced it myself.

Removed screws holding the grill in place. Removed air filter, removed screw holding plate under the filter in place. Reached in under fan cowling to find the thermostat cut-out. Disconnected the two wires. Put the new thermostat in place. Replaced screws plates and filter in reverse order.

I was told by 2 different appliance technicians that the crumbled/melted light socket could not be replaced which meant replacing the entire microwave (expensive!). Other posters on your sight described the repair steps and I gave it a try. The hardest part was probably figuring out which switch in the fuse box belonged to it (now marked clearly). It was a simple matter of unscrewing the bottom panel of the microwave to access the socket, pulling the crumbled/melted unit off and shoving the new one on. I can't believe the repairmen didn't want any part of even giving it a try.

Took cover off, noted the two side by side switches easily visible and we hought one of these was responsible. Then son noted a third switch at the top of the plastic assembly which inserts at an odd angle. When it was inspected signs of a previous short showed up with burnt contact points. Reinserted at same odd angle as there were guide holes, closed things up and oven worked 100%. Great prompt service and great website!! We will use you again

Primary door switch was shorted and blew the fuse when the oven was plugged in. Replaced primary door interlock switch.

I removed both sockets from the microwave and when your part arrived, I installed them both including the new lights. The work perfectly and it was very easy to put them in. I also appreciate the speed of delivery and your concern for my feed back on the product. I have you number in my contact list and should I need another part, I'll check with your first.
thanks you

1. Turned off circuit breaker for microwave.
2. Removed screws holding the bottom cover of the microwave; cover is hinged at the back, so it dropped open and stayed out of the way.
3. Unplugged turntable motor and removed screws that hold turntable motor in place.
4. Pushed broken pieces of the plastic turntable coupler out of the way (hole for motor's axle not big enough to remove them).
5. Put turntable coupler into hole in bottom of microwave interior, held it in place while putting the motor axle into it from below.
6. Replaced screws holding turntable motor in place, plugged in motor's electrical connector.
7. Closed bottom cover and replaced screws that hold it in place.
8. Switched on microwave circuit breaker.
