Yes, the one in the back.
Mine started acting up on a trip home in 2019, then ran ok for awhile. I got to KY to work for Amazon and it quit, lites on front flashing. It would try to start, but then stop. Sometimes I could get it reset by unplugging the front control board connector located under the top left refrigerator door hinge cover. Sometimes it would reset, run for 1 or 2 days, then back to flashing.
Had a Maytag repair tech come out, he thought it was the front board. But he went online and said that there were no service kits available for either board. Basically, replace the whole thing.
Being that it is quite a job getting the unit out of the large slide I decided to wait till I returned to New Orleans at Christmas and get my son to help.
After we got it out I got the part number off the board, W10312695, and found it on Amazon for $171. Took a chance and it worked. Been doing fine since Jan 2020.
It looks like there are some on Amazon, but you will need to find the number on your board.
There are videos on the web on how to remove the board once you get the fridge out.
Good luck. I was not looking forward to trying to replace the whole unit.
