Error code39
ApplianceCooktop
When 39 shows up
This code has a trigger you can name: a new touch control board went in, and the software on it does not agree with the filter control board.
Try this first
Turn the power off for one minute, then restore it. That is the only reset the list gives for this code.
If 39 comes back
Disconnect power.
Replace the touch control board.
When the replacement is ordered again, double-check the part number so it is the right one.
Where it applies
Kenmore induction cooktops numbered 790, using numeric codes with no letter prefix.
Related codes
Code 36 is a communication error between the main power and filter boards.
Code 34 is the filter-side wording of a similar communication failure.
Code 33 reports improper voltage output at the filter board.
Kenmore cooktop repair in San Francisco after a board swap
If a recently fitted touch control board brought 39 with it, a technician can sort out the part number through Kenmore cooktop repair. We cover San Francisco and the Bay Area at (415) 825-6393; mention the model number and the number printed on the board that was installed.
Model compatibility: Kenmore reuses codes across series and model years, so 39 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
