Before you spend the money to replace the Maytag circuit board, call their customer service number (at the bottom of this post) and explain that your control panel is blinking, your ice dispenser trap door is opening and closing, and you want them to help. They are paying for this problem apparently even for out of warranty refrigerators. They will send the replacement and schedule a repairman to come. I didn't know this until after I bought the circuit board for almost $200. The refrigerator was not cooling properly and I didn't want hundreds of dollars of food to spoil so I got the part. The circuit board is easy to replace. UNPLUG THE REFRIGERATOR BEFORE YOU DO THIS. On the back of the unit about halfway up on the left as you face the back is a square silver panel with four screws. Remove the screws and you will see a circuit board behind a plastic cover. Look for the groove on the right side of the cover, put your finger in and pull gently and it will open like a door. The circuit board is held in with two plastic snaps on top and bottom. Push the top one up and the bottom one down, gently, and pull the left side of the board out - gently/gently. It is held to the right side of the small compartment with plastic sticky-outy things that do not move so be careful not to damage the board. Replacing it then involves simply putting the contacts from the old board in the same places on the new board. They are pulled off the old circuit board by depressing the little snaps on each one and then pulling out - gently. Reverse the order as you put it all back in. When you have put the new board in, plug the refrigerator in and then you will see PE0 000 appearing on your display. This means you have to reprogram the unit. Here are instructions for reprogramming I copied from others who have posted on this problem. NOTE: THE REFRIGERATOR DOOR HAS TO BE OPEN IN ORDER FOR THE PROGRAMMING TO WORK. WITH THANKS TO THE DUDE WHO ORIGINALLY POSTED THIS - I DON'T REMEMBER HIS NAME. The code to input is found on the unit serial number and model number sticker on the inside of the unit. You will find "CODE" followed by numbers. Those numbers are your code. Programming Mode: 1.Press and hold the Door Alarm Keypad. 2.Press and hold Freezer Temperature Down Keypad. 3.Release the Door Alarm Keypad and wait 3 seconds. 4.The control will display PE to indicate the programming mode. 5.Entry is confirmed by pressing the Freezer Temperature Down Keypad - once more. 6.The control will display the current Program CODE.The value should be validated with the Program CODE printed on the unit serial plate. 7.Press the Refrig Temp Up Keypad or Refrig Temp down Keypad to change the digit value with each key press. 8.The decimal point indicates the selected digit. Press the Freezer Temp Up keypad to select the next digit. 9.Once the desired Program CODE is displayed, press and hold the Freezer Temp DOWN keypad until the Program CODE begins flashing indicating it has been saved. Then shut the door and your display should be normal. Good luck. Try Maytag first before you spend any money. If you are even slightly handy, once the new board arrives, you can put it in and not wait for a repairman. I consider this important to save food that may spoil otherwise while waiting for a service rep to show up.
