JVM1750DM1BB General Electric Microwave - Instructions

Remove top air grate via 2-screws. Remove metal top panel behind grate that's above bulb via 1-screw. Bulb is exposed and can be un-screwed. DONE

Phillips screws on bottom panel allowed me to install new socket and put electric connection back. Secured bottom panel and that was it.

Unscrewed numerous screws holding the "body/shell" to the microwave. Removed body. I then unplugged top door switch, replaced it with new one, and "tested" the new one. I fixed our $400 convection micro with an $18 switch. NICE!

Followed instructions on You Tube. I had an over the stove model. First I unplugged the electric cord,removed screws from bottom of microwave, removed the 1screw on motor,disconnected the electric wires which just pop off as a unit and replaced the motor and put bottom back on. Easy instructions on You Tube

It took less then 10 minutes to order. Received new part with 3 days

Put it in place. Ordered replacement over internet on Wednesday and part arrived Friday. Very fast service!

Piece did not fit as well as old piece needed to take off a small piece to make it fit. Once it was in the turntable worked again

Handed the part to my son. He unscrewed 5 screws in the base of the microwave, it dropped down. The light mechanism was clearly in view. With the exception of some corrosion on the old piece, it was simple to remove and replace, put back together, screw back up and all worked fine.

removed electrical wires, unscrewed holder, inserted holder, attached wires, added bulb, and put cover back on.

After examination - evidently some one had put a larger dish in the microwave and it stopped the glass plate from turning and broke the holder stirrer(small plastic piece that held the glass plate so that it could turn.
When I received the right part I simply made sure that all the prior plastic was out or out of the way and placed the new part onto to the shaft - tested it a few times, made a minor alignment and it has worked fine ever since.
Thanks to your staff for finding the right piece from the description I gave.

I used the internet and your directions to complete the repair. It was easy!

Removed broken coupler hub and pushed new hub on shaft. Make sure to align the new hub correctly when pushing on to shaft. Repair took less than 1 minute.

Unscrewed two screws and pop it in.

First I replaced the cracked cooking tray and I was done.

My microwave was squealing horribly and replacing the turntable motor (SUPER easy btw) didn't fix it. So I figured it was a spun bearing or bushing in the cooling fan (spoiler alert -- it was!). Installation was simple and did NOT require removing the cabinet-mounted microwave from its position above our stove: Unplug microwave, carefully unscrew the 2 screws holding the vent grate above the door, remove the grate, then unscrew the one screw holding the top of the control panel to the case. Carefully pivot top of control panel down and unhook it from the case (at the bottom of the control panel there are two little legs or extensions that insert into slots in the case). Then disconnect the 3 or 4 wires that attach the control panel to the wiring harness (I marked them each with tape so I would remember where they go, but you can just take a picture with your phone). Set the control panel aside. Where the control panel was, you will be looking at the fan, with a bunch of wires between you and it. Take another phone picture for reference, just in case. Disconnect the various wires, starting at the top right and working your way around clockwise. I marked each wire with a piece of tape and a number, starting from 1 and working my way around an imaginary clock face. I think I got to 12 and then the last two (sort of buried in the middle) I labeled as "0" and "-1" but you can use any numbering series you like. Once the wires are all disconnected you can gently push them aside and unscrew the two screws holding the fan assembly in place, and disconnect the fan wire. Then gently maneuver the fan assembly out the front of the case. Installation is simply the reverse of this simple disassembly process. Voila! Back to a nice quiet microwave.
