KitchenAid KSCS25FVMS01. 11 Years old - manufactured Sep 2008.
Compressor is working, freezer coils getting cold. [br]
+
Bottom of freezer is cold, crisper drawer in fridge cold, but the rest of the refrigerator is warm. Ice maker and water dispenser work when evaporator fan motor runs, but don’t work without evaporator fan motor. [br]
+
No air circulation, fan does not start even though there is 12VDC across red and white wires to evaporator fan..
Here is what I tried already:
1) cleaned compressor coils under refrigerator. They weren’t very dirty, but thought this was the easiest place to start.
2) replaced fan motor with identical replacement. Panasonic UDQT22WP1, 12V DC, 3.0 Watt, Model 2259385. Refrigerator worked for 5 weeks, then stopped again same problem. Confirmed 12V DC at plug. Removed fan and applied 12V DC using alarm battery across red/white terminals. Neither old fan, nor brand new fan motor started.
2) replaced bi-metal thermostat because the old one was pitted. Ice caked up on freezer coils. Did not appear that defroster was working. Old thermostat did not have continuity. Tested the new thermostat - continuity when frozen, no continuity when warm. Installed and freezer coils are cold, but not frozen solid as before.
3) replaced control board assembly. No change in performance. Lights in fridge and freezer go on/off when doors open/close. temperature controls appear to work and respond to +/- arrows. Power off turns off, on turns on.
4) bought a 3rd fan motor from different supplier. Still have 12V at plug, but fan motor does not start either on the bench or in the freezer.
5) Unplugged refrigerator overnight to completely defrost and discharge any static electricity. Restarted, no change.[br]
+
3 different fan motors, none start. 2 different control boards, no change in performance.
