I finally got my new fresh food section evaporator fan + thermistor + defrost sensor assembly and replaced it last night.  After letting it fully defrost, and turning it back on this morning, it appears to be working better.  At least everything shuts off occasionally, which it didn't do with the faulty defrost sensor.

Hello folks, just wanted to post a follow-up to the more-recent portions of this thread. I ordered the replacement fan/thermistor assembly for the Whirlpool fridge I was having the problem with. I removed the evaporator cover in the RC with the intent of replacing the fan/themistor assembly as noted previously. Funny thing! When I went to remove the thermistor from the coil, I noticed it was extremely loose. Loose, as in exactly the condition described and addressed in the service pointer mentioned by Harold's Appliance...
 
As previously stated the service pointer indicates that the thermistor is apparently loose and the repair procedure would be to remove all Frost or ice buidup with a hair dryer or heat gun and secure sensor in place with a plastic tie strap.
So, guess what? I rotated the thermistor clip to a tighter position on the coil, and, like the service pointer instructed, secured it tightly with a zip tie. I'm 6 weeks post-repair with absolutely no ice buildup, RC is keeping consistent temp and no other issues. So I guess it pays to follow service pointers. I've also got a replacement fan/thermistor in case I ever actually need it in the future...

I've got a question about this exact fridge if you can help me please? The ice maker has stopped working. I've replaced the ice maker and heater. The water valve on bottom ohms out fine. I've gone through harvest mode and when I test the water to the ice maker I get a bit of water out the front of the ice maker. As far as I can tell the water spout is in correctly but the ice maker still isn't producing. Any suggestions PLEASE?

in diagnostic mode see test 56 for im fault. Should read E0 for ok. If fill test is done w ice in im it will overflow. Once im is installed I always unplug refrigerator for a minute as a reset. Check temperature in im duct. 10 degrees or less.
Service Test - 56 Ice Maker Error Codes
Displays active Ice Maker Error Codes on the UI display. (E0 = No Errors, E1 = No Cooling, E2 = Motor Lost Position, E3 = Heater Timeout, E4 = Dry Cycle, E5 = Timed Ice Making

I haven't checked the temp in the duct but I did install a new heater with the new IM. I can try the temp but got an E1 code on test 56 after unplugging and raising the front legs. I'm still scratch'n my head?

E1= no cooling. Its obviously not getting cold enough. Thats your problem.. What is your freezer temperature? Is ur ice box fan working?
