Open door. Remove tray. Remove old roller assembly. Insert new roller assembly. Replace tray. Close door. It took more time and effort to unpack it than it did to replace it.
Removed outer case, checked fuse first, it was good so went to thermostat. No continuity reading. Unhooked thermostat, used jumper wires to by-pass break—briefly plugged the unit in. It came on so I knew the issue was definitely the thermostat.
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.
The microwave turntable rotates when the door is open.
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
I took the cabinet off and saw where the switch had been burnt. So I remove it and order another one from your company. And I put new clips on it with heat shrinks. We might get another 30 years out it, Although I'm 80 years old.
Turntable Stopped Working/Display Timer Would Countdown But Not Heat
With this model, you must remove the outer covering. Don't try to access the display unit from the front like I've seen in some other GE microwave videos. After removing the outer covering, the switches are easy to replace. They are very visible and easy to get to without taking any other parts off. You will see the door switches just behind the display board. Remove the switch and then remove the connecting wires to ensure you don't inadvertently brake a wire. You will need a tamper resistant star bit to remove 3 or 4 screws from the back panel. All other screws are philips head. I went ahead and replaced both switches (yes...there are two of them) and works like a charm. I saved an $800 microwave for less than $60 and know what to do if it happens again. Appears to be a common problem on this model. Thanks for others making a post...It saved me time and money reading others remarks. Good luck!
