Error code 33
Appliance Cooktop
Quick answer

Code 33 means the filter control board is putting out improper voltage. Power is disconnected and the harness connections are checked first.

Model compatibility

Kenmore reuses codes across series and model years, so 33 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

Code 33 on the display is about the filter control board: its voltage output is not right.

Checks from the manual

  • Disconnect power.
  • Inspect the harness connections on the filter control board and the main power control board.
  • Connections fine? Then the filter control board is the part the manual says to replace.
