Brand:kitchenAid Model Number: KSSC48FKS00 Main Symptom:Evaporator motor not spinning What happens & when: temperature on the fridge is high and over temperature light is blinking. Freezer bottom section is very cold.
Error Code (if any): no error codes
Parts or tests already tried: tried to replace just the OEM motor with no luck. I suspect the issue is with the harness, but not finding the correct match.
Defrost heater wire connector which I have is flat pin where as one available online are all round pin. Also checked there is voltage from the motor control connection using multimeter

When testing from the red wire to the white wire, is 12 Volts DC present? Also, is there a DC voltage between 5 to 17 Volts DC when testing from the yellow wire to the white wire? Both voltages need to be present for the fan to operate. The 12 Volts DC on the red wire is a constant supply while the variable voltage on the yellow wire is what tells the fan motor to start spinning. The voltages can also be tested for at the main control connection P7 to verify if this might be a wire harness issue. The constant 12 Volt DC would be found when testing from the yellow/red wire at pin 5 to the white/violet wire at pin 9. The variable voltage would be found when testing from the yellow/black wire at pin 10 to the white/violet wire at pin 9. The original wire harness itself can be tested for continuity to identify if it does have a break. However, it appears that this harness has been discontinued by the manufacturer from what I see in this link. 2209119 Wire Harness | Genuine Whirlpool OEM In Stock
Thank you so much for your reply. I’m learning how to use multimeter and I’m trying my best. Based on what you asked, here is the reading.
When testing from the red wire to the white wire, is 12 Volts DC present? 11.4 DC
Also, is there a DC voltage between 5 to 17 Volts DC when testing from the yellow wire to the white wire? 5.9 DC
The constant 12 Volt DC would be found when testing from the yellow/red wire at pin 5 to the white/violet wire at pin 9. - 8.7 DC
The variable voltage would be found when testing from the yellow/black wire at pin 10 to the white/violet wire at pin 9 . 7 DC
There is some voltage whenever I insert the multimeter pins on to the motor socket on the control panel. Sometime it shows in negative then I reverse the pin on the multimeter showing the same voltage in positive
It sounds like the voltage was present at the fan wire connection (11.4 Volts DC should have been enough to get the fan going, even if slowly), which would indicate the main control was sending out the proper voltage when the fan harness was tested. If the fan did not operate when those voltages were identified, and the testing was done on the fan side of the harness (circled in the attached image), it is likely that the new fan is faulty. 8201589 Refrigerator Freezer Evaporator Fan Motor Assembly | Genuine Whirlpool OEM In Stock
