JMW2430WB01 Jenn-Air Microwave - Instructions

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

Remove the oven door. Remove 3 self tappers on rear wall of oven to take off a round access panel. Pull out a pre-cut rectangle of insulation. Next I removed the 2 screws holding the sensor in place. Pulling the sensor out a bit told me I was "touching" the correct wires in the SMALL rectangular opening. The wires are not visable and 2 hands do not fit in this small opening.I looked at the NEW sensor to see the release on the sensor plug. Slip the angled needle nose into the opening and grasp the plug/release side. The plug pulled apart easily. The sensor wire pulls out with a little bit of twisting to fit it out the hole. The new plug pushes in and has to be worked down to where you can reach it. The same angled plier works to re-attach it. It takes longer to read this than to do the job. Best of luck, Al

Everything worked perfectly---thanks to the suggestion of your call center agent. She suggested that since the replacement door handles were no longer available, I should consider repainting them--it worked like a charm. Please tell her she was a life saver. We rent that house in Fl and my returning tenants had complained about the discoloring refer handles. Thank you

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?

If doing this for the first time, it's harder to replace than described by others.

Start by removing the oven door. Reach in to unscrew the two screws that hold the sensor in place on the back wall of the oven. I was working on the upper oven of a double wall oven and found it more comfortable to sit on a tall bar stool while working. Pull the sensor partially out and you will see the connector wire running through the sensor opening. The sensor connector plug is too deep into the oven to reach with fingers or any tool. Next unscrew the 6" round heat circulator fan just below the sensor on the back wall of the oven. Pull the fan partially out and you will see the plug for the temp sensor directly behind. You may have to push some of the insulation of out of way. Unplug the old sensor and pull it back out directly through the sensor opening. Take the new sensor and thread it in through the opening and plug it in. Reinstall the circulator fan and then screw the new sensor in place. This should complete the temp sensor replacement.

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.

Pull the end of the lens nearest the oven door out of the oven wall. Because our oven is several years old and the bulbs had not been previously changed, I could not pull the lens out with my hand, so used two small screwdriver under the metal tabs which hold the lens in place, the metal holder came out with the lens. Once the lens is removed, simply pull out the old bulb and, either while wearing surgical gloves or holding the bulb with a cloth (do NOT allow bare skin to touch the bulb or you will be replacing it again sooner rather than later), push the new bulb's pins into the socket. The lens then is simply pushed back into place.

pull oven, remove back pannel and unplug and remove high limit switch. Repair was the reverse of removal.

I removed the 2 screws holding the sensor in the back of the oven and pulled the wires out. The connector got hung up in the insulation. Rather than pulling too hard, I loosened up the heating element plate and screws and pulled the whole plate out an inch or so so I could work the connector through the insulation. I forgot to shut off the power. When I put the sensor on, I got the same error. I briefly shut off the power at the breaker and turned it back on. The clock on the oven did not reset. It still didn't work. So I took the whole thing out, shut off the power, reconnected it, turned the power back on, reset the clock, and it worked! Should have turned the power off first and I wouldn't have had to do it twice.

I had a service guy come in and he told me the repair would be $550.00. I asked for a part list and did it myself. You guys saved me hundreds of dollars.

I thought the part might not be available. Ordered the part from PartSelect. Couldn't have been easier.

I tryed to remove the sensor from the oven by removing the screws inside the oven. Unfortunatly, the plug for the sensor would not reach the inside of the oven. I had to remove the oven from the wall and remove the back cover to ac3ess the sensor wiring.
After that it was a snap.

Didn't need sensor replaced. After turning the breaker switch back on oven appeared to be working fine.

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.
