Part 00629722 Range Cooktop Potentiometer Spark Ignition Switch
Purpose
Translates control knob rotation into electrical signals for burner ignition and regulation.
Details
The 00629722 is a genuine OEM rotary potentiometer and spark ignition switch assembly located behind the control knob panel of gas ranges and cooktops. This precise electrical sensor acts as a variable-resistance communicator that tells the main control board how far the knob has turned, controlling gas burner ignition timings and ExtraLow (XLO) simmer settings. When the potentiometer begins to fail or suffers electronic wear, common symptoms include burners that click continuously or randomly even when not in use, unresponsive heat adjustments, unignited burners, or jumpy control settings. Replacing this switch resets correct automated resistance levels and re-establishes normal element ignition feedback cycles.
Included Items
One rotary potentiometer spark ignition switch component. Required tools: Phillips screwdriver and flathead screwdriver or putty knife (for knob removal and console access).
