For history on this 2 year old unit, all has been good until about a month ago the freezer compartment was heavily frosted. We returned from a weekend away and found the refrigerator constantly rebooting. There was freezer compartment ice buildup all the way into the evaporator fan. I removed all the ice, it stopped rebooting and it appeared to be working normally. A couple days ago I noticed the freezer wasn't keeping everything frozen, removed the freezer compartment back over and ice buildup had started again on the right side. I used a hair dryer to remove the buildup.
I then installed part # W10639002(ui and control board) for the ice maker overfilling issue and may have misunderstood from other postings, but thought it may help the frost issue also . The refrigerator compartment is set for 37 degrees and and the freezer compartment for -2 degrees. It's been a couple of days and no ice has been made. There is water in the mold and all the service menu tests pass. Does something have to be activated or initialized after installing these boards ?
thanks in advance for any advice.
