Question about Kenmore Refrigerators
Refrigerator will not defrost; I believe it is the electronic control board and want to replace it.
My name is Peter. I am a retired field service refrigeration technician.
UNPLUG YOUR UNIT BEFORE STARTING ANY WORK!
Your defrost problem may be your control board but, that is not where I would start.
In answer to your question, your control board is in the top front of your freezer section. When changing the control board ground yourself by rubbing your hands on something steel. Static electricity will knock a control board out.

More likely your problem is your defrost heater. You check your defrost heater with a multi-meter. Set the meter to the lowest Ohm setting. Place one meter lead on one end of the heater connector and the other lead on the other end of the heater connector. If the meter reads '0' or OL or infinity the heater is bad. It should read something like 35 or greater Ohms.

When changing you defrost heater it is common practice to also change the Bi-meWhere is the main electronic control board located - 25304309-iykvtnwbj1poqn502gcweelx-3-15.jpguploads/images/25304309-iykvtnwbj1poqn502gcweelx-3-15.jpg" alt="25304309-iykvtnwbj1poqn502gcweelx-3-15.jpg" class="h_mi" />

Both of these components are located behind the back freezer wall.
This is a major task to change these components. Bottom freezers are not service friendly.
1.) Completely empty the freezer (Unplugged).
2.) Take off the freezer front door.
3.) Remove the ice maker assembly.
4.) With a screw driver pop off the thermostat cover plate in the back upper right.
5.) Unscrew the back cover.
6.) Remove the center air vent. This is held in with plastic tabs. with a screw driver pop up the center tab and the side tabs.
7.) Pull the back cover out. You will need to flex the cover to clear the side rails.
Unless you are really good with basic electrical and hand tools, I do not suggest you attempt this repair.
A local service company will charge you about $400.00 or more.
