Hi, I have buggy fridge, where the fresh food evaporator will frost up when ever there is too much moisture and the fan stop running. It happens once a while (every 6 months), but much more frequently recently. I think parts are all working after I defrost manually. Can someone suggest what I should do to debug the fridge?

There is a service bulletin on this problem if your refrigerator serial number is prior to HRX40

SERIAL NUMBERS: Prior to HRX40
POSSIBLE CONCERNS: In certain circumstances, consumers may experience warmer than usual temperatures in the refrigerator section, due to ice accumulation on the evaporator.
POTENTIAL CAUSES: This concern can result from multiple possible causes including:
Failed or restricted evaporator fan motor
Faulty or mislocated defrost thermistor
Poor door gasket sealing
RC door not closing properly
Air leaks within the air duct, and evaporator cover assembly.
Evaporator fan not running long enough to clear frost.

Part W11467021 has been replaced by: W11509095

Contact kitchenaid repair, the contractor said I need to replace the foam cover, fan, control module and thermister. Total $600+. Non covered by kitchenaid. Worst for all the technician said the fix is not guaranteed for the same problem to come back. For now I am going to manual defrost to survive another day. I think I need another plan to open the assembly. Do any one know a good video to open the foam cover. My existing foam cover is damaged due to expanding ice. I searched the part # W10648679 and I can't find anywhere.

Yes, that is the correct foam housing part number, it comes with the fan too.

But unfortunately, I couldn't locate the service manual or any video's that show you how to remove and replace it.

I haven't removed one of these as of yet on this model, or I could tell you how, sorry.

Another person had this same issue and this is what I mentioned to him:

Looks like it is thermistor problem. The attached photo show the thermistor cover with grease. It is from wire installation cover by ice. I move the new thermistor away from the evaporator to coper pipe per the suggestion in your other thread. So far so good. Will post final status after two more weeks of observation.

Excellent, that sounds like you found the problem.(y)

Here's that thermistor, in case others need it too:
Temperature Sensor W10316760

Fridge is working properly after 10 days of observation. Attached photo shows the relocation of the thermistor. Used to be directly on top of evaporator. The new location is attached to coper pipe 2 inches above evaporator assembly. It help to keep thermistor clear of the frosting evaporator blades.
