Evaporator Fan Installation Kit For KSS, KSC, and other Whirlpool/KitchenAid/Kenmore/JennAir/Maytag Refrigerators

Another helpful tip from the members of a PCB repair shop!

There has been a lot of confusion surrounding the installation process of a new evaporator fan motor for these KitchenAid (and other Whirlpool Corp.) refrigerators.  Whirlpool provides one replacement kit that is applicable to three different style of refrigerators.  Depending on which style refrigerator you have, you may or may not have to use one of the two jumper harnesses included in the kit to connect the fan motor to the main control board.

Skip to the end of this post to read the installation instructions published by Whirlpool Corp…

BUT, we can sum it up for you in a much clearer fashion:

1) CUT POWER TO THE REFRIGERATOR.

2) Remove the original fan motor. Disconnect the fan motor from the jumper wiring harness that goes to the main control board, but leave this jumper harness in place.  Whirlpool suggests using a flat head screwdriver to unlock the plug, as it is fragile and can break.

3) Install the new fan motor where the old one used to be.

4) Depending on which style of refrigerator you have, you may or may not need to connect the motor to the control board via one of the two jumper wiring harnesses included in the kit:

REFRIGERATOR TYPEJUMPER TO BE USED
Built-in with bottom Freezer

Plain Jumper Harness for Built-in Refrigerators with Bottom Freezer



Add this harness between the original one and the new fan motor.
Counter Depth

Jumper Harness with Defrost Bi-metal for Counter Depth Refigerators



Remove the original bi-metal jumper harness and replace it with this new one.
Built-in Side by SideNONE. Simply, use the original jumper harness that was already in the refrigerator.

The installation kit should have include a black dot sticker.  After the fan motor replacement is complete, apply this sticker to the right of the main power ON/OFF switch behind the upper grille in the machine compartment.

Restore power to your fridge and everything should be good to go.  Remember, get your refrigerator control board problems solved by PCB repair companies!

 

Original Installation Instructions Per Whirlpool Corp.:

This evaporator motor service kit is supplied with one evaporator
motor that can be used for a KitchenAid built-in bottom freezer,
KitchenAid built-in side-by-side, or Counter Depth refrigerator.
This evaporator motor service kit is also supplied with a new
jumper harness for the KitchenAid built-in bottom freezer
(Figure 1) and a new defrost bi-metal harness for the Counter
Depth refrigerators (Figure 2).

NOTE: Must remove existing harness on Counter Depth ONLY
and replace with harness in the kit

If the evaporator motor is being replaced on one of these units,
the jumper harness connected to the motor must be removed
along with the old evaporator motor.

1. Unplug the refrigerator or disconnect power.

2. Use a small flat screwdriver to unlock the plug, slight
pressure is needed to release the lock. Use care, the lock
is easily broken. The two harnesses contained in the kit
are required when the new motor is being replaced.
Replacement of the harnesses to the individual product is
needed for a proper repair and for proper operation.

3. If the product is a Counter Depth refrigerator, the old
defrost bi-metal harness connected to the evaporator fan
jumper harness must be removed. This harness contains a
9-pin connector and the defrost bi-metal. For the Counter
Depth refrigerator ONLY, replace the old defrost bi-metal
harness with the new defrost bi-metal harness contained
in the kit (Figure 2).

If the product is a KitchenAid built-in bottom freezer,
connect the jumper harness (approximately 265-mm)
contained in the kit (Figure 1) to the new evaporator fan
motor.

If the product is a KitchenAid built-in side-by-side, no
jumper harness is needed.

4. Secure all connections.

5. Replace all parts and panels.

6. Plug in refrigerator or reconnect power.

7. Perform the service diagnostic mode by pressing and
holding the Water Filter Reset key first then the Power key
and hold both for 3 seconds. Verify that in step 3 of the
service diagnostic mode, the evaporator motor receives a
green LED indicator on the display for the Counter Depth
product or “01” on the display for the KitchenAid built-in
bottom freezer and for the KitchenAid built-in side-by-side
products.

NOTE: If the call service indicator is still flashing, press
the Over Temperature Reset key.

8. After replacement is completed, the black dot that is
included in this kit needs to be placed to the right of the
main power switch behind the upper grille in the machine
compartment. (See Figure 3.)
