To correctly sort the problem out, you need to replace the magnatron and capacitor with the HV diode. That will definately sort the problem out. Do not do this repair without supervision as a microwave is truly a dangerous item to repair.(Make sure the plug is out when inspecting the components. You must be exact when ordering the componenents. Read off the numbers to the supplier to get the correct items.(Thats if you insist on doing it yourself).

Hello,

Defective or damage digital display - physical abuse is not a recommended technique for getting a microwave oven to cooperate. If there is any visible damage to the digital display, the outer film is broken, it will probably need to be replaced. There are no two ways to this, other than to replace it.

Take care.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing.



At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find your mini-manual, or if you want to look at it before removing the controller, you can download it here (just enter your model number).

You can find helpful exploded view diagrams and order parts by entering your full model number here.

If there is no display it is typically the LCD Module which is located inside the door, the part number is W10143962 and runs $154.00 for the part. Since the door will need to be disassembled, unless you have done this job before I would recommend calling a professional to make the repairs.

On a side note, check with KitchenAid before you spend any money on this, a lot of parts have a 5 year warranty on their products

i bet the store was a very big room? so the sound it makes was lost in all the empty space,,
your kitchen its not nothing like as big so the noise sounds like a jet engine runing over head! and i bet its in a very tight hole in the wall too,

F2.Q1 Not reading keypad
inputs
1. Unplug microwave oven or disconnect power.
2. Replace the user interface board (UIB).
3. Replace the door control assembly.
4. Replace all parts and panels before operating.
5. Plug in microwave oven or reconnect power.

Many of the error codes may be solved by power cycling: unplug microwave oven or
disconnect power. After one minute, plug in microwave oven or reconnect power.

i found this info on a tech sheet hope this helps, let me know how it goes... some of those electronics had 5 year parts warranty i would check that out....Also u might be better of buying a new one if its out of warranrty as some of those boards are expensive, obvioulsy unplug unit first try to reset it self.

EE1 on a Sharp commercial microwave is magnetron 1-related failure.

It may be a bad connection or relay on the control board, a bad magnetron, a bad high voltage diode, etc. - anything in the high voltage circuit for the #1 magnetron.

We have the service / repair manual for a similar model and have uploaded it to our site here to help you.

It will give you safety info, step by step help in disassembly and troubleshooting tips, but do not rely on the part numbers shown in that manual.

You can find part numbers and order parts from Encompass here or you can call them toll-free at 866-779-5835.

Most computers will open the manual automatically, but you may need the free Adobe Reader

Doors for microwave ovens are usually replaced as a complete item. I would ask the person who forgot to fix the door latches properly back to fix it properly. If some of the clips were snapped off when removing the door panel, the panel must be replaced or it will fall out again.

I am a bit late on this question, but just ended up in a rabbit hole of unanswered Kitchenaid questions The self cleaning features only serves to keep manufacturers in steady sales of parts. Quite simply the oven can only take those temperatures a few times until they break. The heat burns out elements, damages fans, door locks and worst of all damages control boards which are not far enough from the heat source. You problem sounds like the walls of the oven have buckled in the heat so the racks no longer fit. Too late now, but you should have taken Kitchenaid to court, the oven was not fit for purpose under the description they used to sell it to you. Never use the self cleaning feature as stated here https://www.google.com/search?q=self-cleaning+oven+temperature Never Ever use the self clean feature. We see damage here every couple of weeks. The worst was a burned control board on an oven that all parts were obsolete, so the self clean cost a thousand bucks! Self-cleaning ovens bring the heat so you don't have to spend hours scrubbing. Traditional self-cleaning cycles heat the oven between 800°F and 900°F, helping turn soil and spills to a powdery ash you can then wipe away. They utilize only heat-no chemicals-and are built to withstand high temperatures. (Says Maytag who love selling elements, door locks and other parts),
