JVM1440BH04 General Electric Microwave - Instructions

I first took the filters of the exhaust and then removed the screws on the bottom of the combination microware hood fan. Once the 6 retention phillips head screws were removed from the bottom of the microwave, and the hinged bottom "door" lowered the motor was exposed. I removed the motor by removing the two phillips screws and unplugged the motor. The hardest part was finding a replacement on the net because most shops did not give enough details or pictures to know if a part was exchangable or a replacement. Partselect.com listed the parts, motor voltage, and had pictures so that I was comfortable with ordering. The part arrived the day it was scheduled to and I simple reversed the process and within 5 minutes I had the microwave motor in and back together. It is nice to do business with a place that also gives you a returns policy upfront.

Removed upper cover. Removed screws in cover plate & motor mount. Removed inner cover with pop screw inside microwave. Reversed procees to install new motor.

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.

Went to onlin source, found a couple youtube videos then went to the GE site which had a not-too-easy that find trouble shooting guide. It was extremely helpful as it described a fuse as a fix 80% of the time for touch paid failure. I really didn't believe it would b a fuse, but it was the cheapest fix, $8. I got the fuse and was surprised to fine there are two of them on this model. I took a guess and replaced the top one ( neither fuse was black or burned to indicate a failure but the top one was a bit mor greyish). put it all back together and it works fine.

took off upper grille and touch pad and removed the old line fuse and replaced with a new fuse ...turned on it is working fine...sources of help: UTube and GE manuel

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.

I followed advice posted here, and used the knife to pry apart the plastic front away from the door housing. I then had access to remove the 4 screws holding the handle in place. I then installed the new handle with the 4 screws. But one thing to look out for is to first screw in the outer 2 screws, then secure the front panel, and then screw in the 2 inner screws. Saved me lots of dough!

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.

After finding the part on PartSelect, ordering it online, receiving it quicker than expected -- it took me 5 minutes to unscrew the bottom cover of the microwave, take off the old motor, replace with the new motor, screw the cover back on and test the WORKING cooking tray drive motor.
Very impressed with the efficiency of PartSelect. It's web page was easy to navigate. Thanks.

I looked up the parts of the microwave on Part Select to see if there might be something I might be able to do myself. I found that the Cooking Tray drive motor was the problem. I ordered the part and got it the very next day. I loosened the 6 screws to the lower part of the microwave and then the two screws that held the part in place. I removed the element and pulled the wire plug from the element, placed the new element back in with the screws, repluged the wire, placed the lower cover back to the microwave, tested the microwave out and, is still working quietly as if it were new. Thanks to part select.com it was easy.

I gently removed the plastic outer cover of the door. I was able to remove two screws. I then removed the inside plastic cover, that allowed me to remove the two inner screws. I replaced the handle, screwed in the two inner screws. Replaced the inside plastic cover. After that I screwed in the two outer screws. The handle was secured. I then replaced the outer plastic cover. I was surprised at how easy I did it. It looked hard at first. I felt good about myself afterward, and save a lot of money.

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.

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.
