• ** REMEMBER! **The microwave can still shock you even unplugged!!

    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

FIXED KitchenAid Microwave KMCS1016GSS0 control board source

No. CA
Model Number
1-5 years
I'm having semi random intermittent display issues and frequent loss of some buttons working.

I've read the control board is the likely culprit, however none of the popular parts sites list a control board for this model.

I removed the board yesterday, and the part number is MD1001LB version M1.31

I found a board on eBay that is a different version number and I've ordered it, and it should arrive in about a week. I'm not sure it will work, but it wasn't much $$ and the seller said he'd accept a return if it didn't.

So, I'm wondering does any one have a source to order a control board for this microwave?

A pic of my board is attached, along with the model number tag.

Thanks in advance,

part number is MD1001LB version M1.31
Those are lot numbers and the manufacturer of the board numbers, not Whirlpool numbers. Take the key tail out of the board connector and clean the end with a pencil erasser then re-seat the key tail in the connector.
I'll try cleaning it.

As far as the part number, yes it is a mfg part and version number for the midea board.

I cannot find a whirlpool part number for this unit and whirlpool support was no help when I called them.
Cleaning the ribbon cable did not help the display. We will see if the intermittent keypad is improved. It worked about half the time and the keys that did not work varied.

Thanks for looking Rick.

This morning I reinstalled the cover, plugged it and it worked fine. about six hours later I wanted to reheat a cup of coffee and the 5, 7, 0 and Start buttons don't work.

Unplugged it for 20 mins and tried again with the same results.

The behavior pattern has been once the start button stops working, a few hours later or the next day it will work again. Then some time later it will fail again.

The board I ordered from eBay will arrive next week. I'll update this thread then. ( fingers crossed )

The board from eBay arrived and is installed.. ( drum roll........)

The good news: It works. I have a functioning microwave.

However this board must be for a different brand, and a few things are not quite right (details below)

I can't - and won't complain since this seems like the only option vs replacing the microwave.

Things that do not work correctly with this new board:

1. Cook Power does not seem to work. Before I would set the time, and then the cook power. The cook power does not appear work at all, or I don't know the correct sequence to use.

2. LCD color is green vs. the KitchenAid silver/grey. Overall it is not bad. The green is subtle and not a loud, bright green and it is not overly bright. It could have been worse if the color was red or the bright blue used on my previous whirlpool.

3. The Timer and Clock buttons functions are swapped. The clock button runs the timer, and the timer button sets the clock. work. I'll get used to it.

Thankfully the start and cancel buttons are not swapped. I was concerned this would be an issue since on the whirlpool that this replaced the start and cancel buttons were in different positions.
The kitchenaid ( pic above ) has cancel under the 7 and start under the 9, where the whirlpool has start under the 7 and cancel under the 9.

I rarely use any of the presets like Pizza, Potato, DinnerPlate reheat, and they all seem to do something, but the display codes are not very intuitive.

Overall I rate this board an 8 out of 10. subtract a point for the cook power not working, a half a point for the timer/clock button swap and a half point for green vs steel gray.

However, given the price including shipping of $31.80 ( USD) the board gets a 10 out of 10 for value.

@rickgburton thank you again for researching the part number. It is still annoying that KitchenAid / Whirlpool do not have a replacement available.
Looking closely at the differences between the boards, the eBay board had a sticker on it with this number: EMLAAMR-S1-K in addition to some numbers printed on the circuit board.

On the original board were these numbers:

google only had a match on the third number: EMXAUWX-S1-K which was an eBay listing for a board that appears a little closer to mine.

The numbers are the same except for the version number: M1.34 vs M1.31 on my original board.

So, I ordered the second board. a little more money but if it has the same color display and if the controls work then it might be a winner.

I'll post another update in a few days.
The second board from eBay arrived and it works perfectly.

with perfect 2020 hindsight I can now see the part number is EMXAUWX-S1-K

In my original post, there is a small line on the board next to this number. I presume that is the "mark" that it is this part number.

On the replacement board the mark is more obvious.

I presume the other part numbers are options that the PCB can handle.

So, final report.

The display color matches the original, and all features work as expected. Clock works. Timer works, Power level for timer works.

@rickgburton Thanks again for the discussion.

Just saw that you got this problem fixed. I am having the same issue with the board (only 3 buttons work on the microwave and display is missing a segment). Just wanted to see if you could share link to where you bought the part. I see there are a few dealers on ebay.

Thanks in advance!
@danman111 I will PM you a link. I'm not sure the forum wants links to eBay listed.

the seller I bought my board from on eBay was auburn_appliance in Rockford Illinois

there is a listing with this title "WHIRLPOOL Genuine OEM EMXAUWX-S1-K Microwave Control Board WMC30516HZ" that is like what I bought.

Please read all the "microwave can shock you warnings" before installing, but it was a fairly easy installation once it arrived.

Thanks Dan. Was just wondering whether you had any new issues with the board? The last board I had lasted exactly 12 months and a week (1 week out of warranty lol) and I would prefer to just replace the whole thing if I'm going to have to keep rebuying this board consistently. Seems like this is a pretty common issue if you read the reviews on Kitchenaid's website.
Yeah. the microwave is expensive, however it matches the rest of my appliances or I would replace it.

The board is not cheap either, but better than almost $600 for a new microwave that appears to be the same identical unit.

No issues since April 5th.
I have the same issue where an LED segment is missing. Then some of the buttons, including the start button, does not work. I have Choice Home Warranty and they offered a $200 Lowe's gift card instead of a full replacement. A new microwave that can fit in the current opening is too expensive, not to mention difficult to find one that will fit perfectly.

I did a Google search for the microwave model number: KMCS1016GSS0 and found this blog. I just ordered this part from eBay: ebay.com/itm/313442528064 for $64+tax, free shipping.
This thread is Fantastic ! Same micro, same issue. Opened the unit and found the EMX… board, will look online to purchase one and give it a try. Also i will read the “shocked even when unplugged” thread while i wait for the board - thanks so much !
