Question and Answers


Kenmore electric range, Mod 66595143300, control board bad.


It is unusual for you to have that many control board failures. I am glad that you checked the elements and the sensor. A short in a circuit that is connected to the control board can cause premature failure. I provided a wiring diagram in the first image below. You can unplug the range and check the wiring connections for any visible problems. The wiring diagram shows a voltage suppressor that is connected to the terminal block. There is a possibility that you could have a problem with that component. You can access the terminal block (with the range still unplugged ) and check that board for damage. That suppressor is shown in the second image below. If you see damage or a burned spot on that board, it could be causing your problem with the control boards failing. You may need to carefully remove that board and check the back of it if you see no damage or burned spots. If that part is apparently bad, it will need to be replaced. That part is no longer available from the Sears Parts source but it is available through other parts websites such as Repair The part number for the suppressor is 9757047.

If that component appears to be okay, then I recommend that you check the voltage at the outlet (or have an electrician perform this check if you are not comfortable checking live voltage). If you are confident that you can safely check the voltage at your range outlet using a volt/ohm meter, you can use the diagram in the third image to verify that you have a proper power supply provided to the range. If the voltage on a leg is less than 108 then it can eventually cause the premature failure of the control board. NOTE: You should only check this live outlet voltage if you are completely confident in your technical ability to safely measure it .

If the voltage is okay and you find no apparent problems with wiring or the suppressor, then you may want to have a technician physically examine the range. Here is a link for the Sears Service website: Sears Home Services .
