Customer Questions and Answers for Infinite Switch (Surface Burner Control) by Whirlpool

This surface burner infinite switch sits behind the knob and regulates power to the cooktop/range element. Replacing a failed switch restores accurate heat settings so the burner can turn on, modulate properly, and shut off as expected.

• Regulates on/off cycling of the surface element to achieve the selected heat level
• Sends power to the burner based on knob position
• Common failure symptoms: burner won't heat, only runs on high, won't shut off, or heats erratically
• Knob turns but the burner does not respond

• Disconnect power at the breaker before servicing; surface elements operate at high voltage
• Pull off the knob and remove the control panel/backguard as needed to access the switch
• Transfer wires one at a time from the old switch to the matching terminals on the new switch
• Align the shaft to fit your knob, reassemble the panel, restore power, and test operation
