JMC2127WB01 Jenn-Air Microwave - Instructions

I used a Google search to show how to access the area behind the front panel. There was a folded paper copy with a schematic and wiring diagram in that space.Then I used a multi-meter to determine which of the THREE micro-switches was causing the problem. I called your help line and ordered a replacement switch. The switch was delayed in transit so your agent credited me with the cost of shipping.

When the part arrived, it had three terminals instead of two as shown in the on-line picture but that did not cause any difficulty in using it. It took about 20 minutes to remove and replace the old switch.

All seems to be working well now.

Finding which of the THREE switches was the problem was the most difficult part of the repair. All three "clicked" but the defective one did not click as easily. It needed to be depressed more than the door latch can would provide. Old age?

IMPORTANT: DO NOT TOUCH THE REPLACEMENT LAMP WITHOUT WEARING CLEAN GLOVES. FILM OR FINGER PRINTS ON THE LAMP GLASS WILL CAUSE PREMATURE FAILURE OF THE LAMP.

Remove the 4 screws on right and left mounting rails that hold the unit to the kitchen cabinet.
Remove the oven door
Remove the chrome oven vent strip below the oven door. This allows a pry point beneath the combo microwave oven assembly to lift up the unit while pulling it out. (Assembly weighs 250 pounds)
Pull the unit out from the cabinet housing about 2-3 inches to reveal the right and left sides and the 4 screws holding the the control panel.
Remove the 4 control panel screws and pull off the face of the control panel
Remove the 2 harness connectors and the ground wire holding the control panel to the unit.
Unclip the circuit board above the lamp connector and slide it back out of the way. The lamp is now accessible.
Remove the lamp spring holding the lamp to the cabinet.
Remove the old lamp
Install the new lamp using clean gloves
Reassemble in reverse order.

Should be about 1 5/8 inch with 3/8 inch prongs. Sent bulb won’t fit.

Could not complete the repair due to broken part when arrived. Reached out to service department but have not heard back. Maybe email did not go through due to pictures attached of part condition once arrived.

EASILY REMOVED GLASS COVER INSIDE OVEN AND REMOVED SMALL HALOGEN LIGHT BULB.
RECEIVED REPLACED WITHIN TWO DAYS OF ORDER AND REPLACED BULB AND GLASS COVER IN ABOUT 10 MINUTES.
MOST DIFFICULTY WAS HAVING TO BEND DOWN TO REACH INSIDE OF OVEN TO LOCATE POSITION TO INSERT BULB.

exact part in with the new out with the old

We had to remove screws from the vent covers above and below the microwave, then there were 2 screws (one on each side) that attached the microwave to the oven. Once all of the screws were removed we had to pull the microwave out. Then we pulled the light cord out, removed the burnt out light and installed the new one. Then reversed the steps.

Took off outer cover Popped out old bulb put in new one
Replaced cover

All other measurements were similar and fit properly. The drive shaft of the coupler was TOO long by about 3/16". I had to cut it down to the size of the original OEM shaft using a fine cut hack saw. Seems to work perfectly now....
