JES1456W General Electric Microwave - Instructions

Pulled motor from bottom of unit to remove coupler pieces. New piece just pushed on without disassembly.

Should have don it sooner. Great people in the order department and customer service. The first piece arrived in a bubble envelope and was broken in 3 pieces. GE quality. Second part was sent in a box. Ladies on the phones here were
TERRIFIC!!!

however, I had hit the cook button and the microwave did not have an item to cook inside. Resulted in shattering the glass tray and meting the plastic lid sitting inside which was fused to the cooking tray. Carefully wrapped up the shattered tray and melted lid in heavy paper, deposited it into the garbage, then happily placed my new E.O.M. glass cooking tray into my G.E. Profile microwave. Thank you .

I first read where someone had the same problem. Their solution was a burned-out fuse. I ordered a new fuse...installed it and that did not solve my problem. I revisted PartSelect and read how Marla (from Arlington, TX)solved her problem. I purchased a secondary switch and when it arrived, I made a copy of Marla's instructions and followed them to the letter. I installed the new secondary switch into the secondary space, put everything back together and the oven STILL DID NOT WORK. I had to take the latching panel apart again and test each switch to see if there was another bad one. I found that the third switch was burned out. So I took the new switch out of the second slot and installed it into the third slot. I tested the switches before reinstalling the latching panel. This time everything worked. So I put everything back together, reinstalled the microwave on the wall, tested it again, and everything worked perfectly.

-unplug
-remove top and front covers
-unplug wire connectors from heating assembly
-remove heating assembly from metal stand and push out of the way
-remove metal stand from dry
-pull out heating assembly
-install new one in reserve order

Removed the control panel, one screw at the top. Removed 2 screws on the door switch holder and removed the door switch. VERY EASY.

The breaker was tripped but fuse was ok on testing. I kept the fuse for possible future repairs. To access door switches and fuse on this model JVM1850CF001, remove 2 phillips screws at top. Then slide the grill to the left (toward hinges) about 1 cm and it should easily come off forwardly. Remove phillips screw underneath grill attaching the main panel. Lift the panel 1 cm and it will easily come off forwardly - I let it hang by the electrical cords. Now you can see/discharge capacitor(s). Remove 2 star screws inside door to loosen/remove/access door switch frame. 3 switches are held in the frame by plastic tabs - one tab per switch. One is primary and 2 are secondary door switches. I removed each switch one at a time by lifting tab, pulled off the electrical connector and filed the male metal connection on each switch. I replaced the switch with a loose button (loose and didn't click as crisply compared to the other switches) with a new secondary door switch. It was the lower secondary switch. Worked like a charm after that.

remove cover, unplug secondary door switch (top switch)
remove switch from holder, install new switch, plug in wires, replace cover, very easy. door switches are a common problem
with microwave ovens.

Replaced the fuse. Result; did not fix the problem.

after a couple of misfires, got the correct size tray, and replaced it in the oven.

Replace the fuses

remove cover-unplug wires from secondary switch-remove switch-snap in new switch-plug in wires-replace cover-works great. very easy to do.

thank you very much.

removed access panal, found soft switch as discribed on your web site. removed and replaced.

I googled "Microwave stopped working", and after reviewing numerous websites with suggestions, I found the response noted below at "Help Owl" which was the most straighfoward and clear explanation to trouble shoot the problem. I first tested the Thermal Cut Out (TCO) per the instructions below and that was the problem. I didn't have to test the electrical fuse. Turns out that you cannot typically use the microwave continuously for more the 12 or 13 minutes or it may overheat and the TCO will shut it down. Extremely easy to test for and fix, and the part is only $15! See Trouble Shooting steps as follows: Make sure that the unit is vented properly and that if you are using it for prolonged periods while cooking, that you turn-on the vent fan.
If there is no display / power within the unit...first check your power source where you plug the unit into the wall.

If that is good, Remove the Cabinette/Cover "Note: it has 3-Torx Anti-Tamper Screws".

Then as you face the microwave from the rear, at the left rear corner is a small circuit board with a fuse. "Check the Fuse"

If the fuse is good, Check the following:

1 - The most common component failure is the "Cabinette TCO" (Thermal Cut-Off Thermostat).

As you face the microwave from the rear...It is located under the cover, on top, on the left front corner area.

It is a Circular, Black & Silver Disc Shaped component about the size of a dime in diameter and is about 1/2" in height.

It has Two (2) Wires attached to it's spade connectors and it acts as a safety fuse.

"IF YOU PUT AN INSULATED JUMPER WIRE ACROSS THE 2 TERMINALS THE POWER SHOULD RETURN AND THE DISPLAY WILL LIGHT"

Anything other than these two items should be checked by an Authorized Service Technician as these microwaves have components thay carry "HIGH VOLTAGE SHOCK HAZZARDS"

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.
