JMW3430WP00 Jenn-Air Microwave - Instructions

Part No. PS11766760
Ignore the other repair comments on this page!!! The new replacement part can no longer be put into place as simply as the original bracket. This is a r3eplacement part with a modified design. Significant parts of the microwave (MW) must be dismantled in order to provide access for insertion of the new part. This is confirmed by notes at other web sites which provide this part. My approach also required cutting/drilling holes into sheet metal panels.

Kitchenaid/Whirlpool must have realized that the original part is inherently weak at the point at which it is supported at the ceiling of the MW. The replacement part is a good option from a strength standpoint, but a horrible one for ease of insertion. The original is a single ceramic piece. The replacement part includes a metal clip which holds the top stem of the ceramic bracket from the top ("roof") side of the MW. Getting at the top of the MW cavity is the difficult part. One needs to pull the entire built in oven from its location and remove at least the control panel from the front of the unit.

It took me 3-4 hours one day to see how to install the replacement part. I failed since I unexpectedly found that there are two sheet metal panels above the MW cavity which need to be removed in order to access the slot through which the bracket stem must be inserted. Maybe somebody else can think of a way to remove the metal panels, but I could not do it so I put the MW back together again.

After this failure I considered trying to repair the original part again (this was the second time it had broken). The first repair broke when the conventional heating element was used in the MW. This option might again be an interim solution so I went back to trying to install the new replacement part.

This time it took over 3 hours to remove the control panel, several wiring units, a transformer, and several side and top sheet metal panels. Each removal step was preceded with a photograph of the item to be removed so that everything could be put back as they were originally located. After all of this work it was determined that the MW would have to virtually be totally dismantled in order to access the bracket slot at the top of the MW cavity. There were simply too many items on top of the sheet metal panels to allow for bending the panels up to access the necessary slot in the oven ceiling.

Fortunately, my wife asked why I didn't consider drilling through the existing sheet metal panels at the top of the MW. Had she suggested that earlier in the dismantling, it would have saved hours of work.

After reassembling the side panels I drilled access holes through the two sheet metal panels over the top of the MW oven. Certainly one needs to be careful in measuring the location for such holes. The holes were to be rectangular, developed by drilling multiple holes around the perimeters of the final "holes." The two sheet metal panels are about 3/4" apart and the lower panel is about 3/4" above the MW oven cavity. After drilling out the holes (about 1/2" x 1") I successfully found the desired slot in the oven ceiling. Then the drill cuttings needed to be cleaned out with a vacuum cleaner - including inside the MW oven.

Inserting the replacement part was not trivial. One needs to hold the ceramic part in the oven, with the heating element in its proper place on the bracket, and then simultaneously place the metal clip onto the stem which has been inserted through the slot at the top of the MW oven. Long tweezers are handy for putting the clip into place. Then the fun begins. Somehow the metal clip must be pushed down onto the ceramic stem. This is a trial and error task with various long blunt tools used to try and push the clip down while not pushing it off to the side. Somehow I got the clip onto the stem and the part was finally in place.

Another hour (+) to re-assemble the MW and push the oven back into the cabinet and the job was finally done.

btw, the only reason it was relatively easy to pull the oven out of the cabinet (and push it back in) was that we have two office chairs at home (without arms) which come up to about the right height for having the oven sit on the chairs. Adding some 2x4's on the seats of the chairs brought it to exactly the right height. The wheels on the chairs also helped. Given the weight of the oven, removing and replacing the oven unit is not a trivial task and one needs to be careful at all times.

There were several observations I made about the new replacement part which also "froze me in my tracks" early in this project. That is why I kept thinking of ways in which to repair the original part more effectively than I had done previously. The problem is that the ceramic section of the replacement part is not the same size as the original. It holds the heating element higher against the ceiling of the microwave and the horizontal section which holds the heating element is shor

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.

Easiest repair I've made in years. Didn't even need a tool.
One end slides into a hole in the ceiling of the microwave/convection over, move the heating element into place and turn the mounting bracket and you're done.

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?

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.

Initially I called kitchenaid and the representative suggested I call one of thier designated repair guys to come out for 120.00. Fortunately, I got the part number and model and found it on this website. It was so easy to replace!! Just fit it in the designated opening and twist it until secure. So glad I did not call out the repair man!!

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.

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.

We bought a really nice microwave for about 1/3rd of the MSRP, but it was an open box item and when we got it home we found that it was missing a bracket on the inside of the microwave. We were able to replace the bracket easily thanks to partselect.com.

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.
