JE740WW02 General Electric Microwave - Instructions

Removed control panel first then removed bracket holding door switches 8 screws total very easy fix ????

After researching on line and watching installation videos, ordered all three switches and installed. Disassembly of microwave was simple, removing the bracket holding the switches was a little tricky, it sits behind a metal post and you have to angle and wiggle it out. One note of caution when replacing all three switches, be sure to install correct switch in correct location. Had two of one style switch and one of a second style, and put one in wrong place, causing microwave to power up again when door was opened. After thinking it through and doing a second disassembly, and double checking installation instructions, corrected problem and microwave now works fine.

I replaced the switch at the bottom per instruction. I had both switches. I think it was the monitor door switch.It works fine now. Thank you Part Select .

Most of the effort is simply getting the oven out of the built in enclosure and the sheet metal off. This take about 15 minutes then you have to remove the two screws (not handy location) that hold the door latch/switch assembly so you can remove the switch. I did this BEFORE ordering so I could test the switch (it was charred) and verify the part needed. WATCH OUT - some ovens use a normally open an some a normally closed version of this switch - you have to get the right one. I checked several suppliers that were showing the WRONG switch for my model. PartSelect had it right. Once I received the switch I had it on and the oven installed and running in less than 30 miutes. Working fine since then...

Took the front panel off, played with the switch while it was plugged in to verify the switch was bad. I actually was able to tweak the switch just right to keep the microwave working while the part was being delivered. When it came it was just removing two small screws and replacing. Very easy.

I purchased the fuse and 3 door switches from PartSelect. Replaced the fuse first but that did not solve the problem. Then I replaced the 3 door switches and problem solved!! So fuse only cost $5.00 so glad I have a new fuse in there as well. To see how to replace door switches see videos on utube!!

remove the housing,replaced the magnetron and reassembled.no problems at all

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 the online videos to enter the cavity to the switch holder. Noticed right away the dreaded capacitor was in back right corner behind where the touch pad had been removed. I isolated the capacitor with an old computer mouse pad for extra safety. Took some manipulations to get the switch mount out from behind the wire bundles. Once out front, easy to use small flat blade screwdriver to release each switch and replace with matching new switch. Only one switch was bad but replaced all three. Back together and working great.

Two screws to remove upper from vent. Two screws to remove the didgit panel lift ip to remove and put aside remove the two screws that hold the door sensors. Depress the tab to remove the defective sensor disconnect the electrical connector and replace the new sensor snap it back into the holder install the two screws, install the didgital panel and vent panel to complete the job. Please be aware that there is a video of this procedure on Y tube

completly removed outer cabinet,discharged capicator,removed some internal parts so I could get at the magnetron,
.removed replaced magnetron,reinstalled inner parts& cabinet .tested microwave viola
everything worked again.
Thanks, PartsSelect

Removed the outer cover to access the door switches. Turns out there were three switches, but I determined that only two were bad. When the small colored tab on the switch is pushed in it should make a clicking sound. The two bad switches had no resistance and did not make any noise when pressed. Removing the switch is relatively easy, you simply pull it away from a couple small tabs holding them in place. After reconnecting the wire leads, insert back into the holding tabs and install the cover.

This is sometimes described in other repair notes as "microwave 'runs' when door is open."
With power disconnected: Remove the microwave's metal grill surround. Three lower screws accessible with lower oven door open. Two screws accessible at top of microwave door opening with door open.
Remove microwave control panel: Remove two femaleTorx head screws (#27?) that secure the panel, accessible at right side of door opening. The right side of the control panel is secured by plastic tabs fitting into slots in the oven frame. Take good care to note how these tabs disengage from the slots (lift and shift). Tab breakage very possible! Once disengaged, the panel hinges outward and downward and is self-supported. It may be necessary to guide some of the wiring out of the way to fully lower.
There are three door switches, one "monitor" and two "secondary" switches. All switches are housed in a plastic frame, which must be lifted out of position for access, each switch is retained by flexible plastic, breakable-looking hooked fingers. Also note that the electrical connectors have tiny release tabs that must be depressed in order to pull them off of the switches. In my case the topmost switch, one of the "secondary" switches, was clearly bad since there was no "snap" or click when pressing the switch's button. Maybe you can determine which switch is bad before proceeding but I had ordered all three to avoid going through this exercise again any time soon.
Replace switch or switches, place switch carrier back into position and otherwise reverse the disassembly steps.

I found an exploded view diagram of of my microwave model which was very helpful. You need only remove outside metal skin by removing 4 screws on either side and 4 more on the back. Remove 4 plastic hole plugs from the top mounting inserts. Gently pull sides out and lift up and back to remove outer skin. The fuse is located on the back right corner behind the control panel. You access from the side. The fuse is under the spreader bar. Lift fuse up gently to remove.

P.S. It was the MSP Capaciter and or the interlock switch, snap apart 21A (19) failure that actually caused the ceramic fuse to blow.

Pulled it from the wall remove the front vent covers removed the control panel remove the door switches by a special screw driver bit which looks a star remove the electrical terminals pressed the plastic clip pulled the switch replaced it with new one then followed initial steps backward
