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.

Water in the mold?

What's your actual freezer temp?

There's water in the ice maker(mold-I was referring to the tray that holds the water to form the ice), the fan works and if i use the service menu to harvest the ice it ejects the cubes.   They look clear though.

The freezer temp was monitored over a few hours and is in the teens and 20's.   The refrigerator temp is set for the recommended 37 and measures at 40 degrees

Sounds like you have a cooling problem in the Freezer, if there was ice buildup only on the upper right of the evaporator, there is a sealed system problem (leak). I may be off a little, but I think that most WPL Ice makers will not harvest the cubes unless the bimetal in the IM is below 13 degrees.

yeah,  you're right needs to be 16 degrees according to this:

from Technical Training Pointer #: W10642142

"When the unit begins cooling, the fan in the ice box draws air from the freezer. When the Thermistor on the ice maker senses a temperature of 16 degrees the ice maker will begin to cycle. The ice ejector fingers will move around until a switch inside the ice maker head closes. When the switch closes a signal is sent to the high voltage board; the board then supplies voltage to the fill valve and the ice maker fills with water. NOTE: At the same time as the ice maker is filling with water, the fill tube heater will be energized for 45

minutes to prevent the fill tube from freezing.

After fill, the ice maker will go into “Hibernation” for 45 minutes. During this time, no power is supplied to the ice maker motor. After the 45 minutes hibernation period has expired, the board will monitor the ice maker Thermistor circuit and corresponding temperature. If the temperature is below the 16 degree mark the ice

maker will harvest and start the process over again."

 

So, sealed system leak, doesn't sound like a diy homeowner job ? I'm guessing  I need a new freezer compartment evaporator and somebody to install it?

Yup. Sounds like a sealed system leak to me.

Post a picture of your evaporator so we can see the frost pattern.

And yes your correct. This not a diy job.

And YES, that is diffinitely a sealed system problem!

 

The complete evaporator should look like that little section up in the top right hand corner.
