Panel flashing, ice door opening and closing constantly
Came home from work today and the display unit on the front is blinking every light and the ice dispenor gate valve is opening and closing by itself. I unplugged it for a few minuites and it worked fine , then after 3-5 minutes it started again. I checked the connection at the top of the door and it was ok.
I have the GE monogram side by side, and it started releasing ice all on its own. No one was even near it. It would not stop until the freezer door was opened, but resumed as soon as the door was closed. Finally stoped it by using the lock button, but cannot release the lock as it will release ice again. So esentially, we cannot use the outer ice and water dispenser at all. Please let me know if you come across the solution.

there is the HV board on the back under a cover . 2 680uf capacitors @ 35v are likely domed instead of flat on the top and are likely hot. replacing these with an equal value will cure the problem. they are in parallel so 1000 and 470uf will cure it. mine was same model except white. local dealer said no warranty. did not call maytag but he indicated it might help. good luck
The red light should flash twice , pause then flash twice constantly . If you close the flap on the left side , then the light should go off . This shows the optics (ice maker cut off ) are good .
Check the black tube ( fill tube ) , which puts water into the ice maker , to see if it is iced inside . If so , then the water valve behind the refrig is bad . It seeps into the tube and freezes , blocking the water flow .
Pour about 2/3 cup of water into the ice maker . If it freezes and dumps , then the water valve needs replaced . If it doesn't dump , and stays frozen in the ice maker , replace the ice maker . Also , make sure the coils under the front of the refrig are clean , as this will cause warmer temp in the freezer and the ice maker needs 5 degrees to operate .
Sounds like you need a new display pwb. The flapper for the ice works on a solenoid which is on a little board that is behind the display board. When the power is cut the flapper should close as it is on a spring. I don't believe that there is any worries of it catching fire. Have a tech come and replace the board for you.
LG's bottom mounts have had problems with air leaks in freezer making a iceball right under the evaperator fan actually coming close enough to the fan blades to slow them down or stop them all together also causeing the FFerror meaning the control board is not detecting the normal RPM's you should to keep it cool enough. Suggestion take the back panel off and remove any ice carefully if this be the problem. Make sure all doors are closeing tightly and gaskets make a air tight close.
I had the same problem, with this model and it was the high voltage control board located in the rear. Replaced the board and it is working OK. Maytag Part # 12920710 will work on this model and it is 40.00 cheaper than the one it shows when you do a parts search. It will come up 12920709. I checked with Maytag and they said 710 will work..
See the post on Samurai Appliance Repair Man's site http://applianceguru.com/forum1/13035-1.html for instructions on how it's possible to fix the HV Controller Board power supply filter caps for $5 in Radio Shack parts (really!). You need to be able to solder electronic components, or know someone who can. There are 2 power supply filter caps that appear to go bad and the result is the blinking and flapping. I had the same problem and decided I could not wait for a $150 replacement back-ordered board.
