Whirlpool Dual Surface Element Infinite Switch Kit - 12002121

Whirlpool Dual Surface Element Infinite Switch Kit - 12002121

Regulates electrical power to a surface heating element so the burner knob can control heat output. A failed switch may cause a burner that will not heat, stays at one setting, overheats, cycles incorrectly, or remains energized after the control is turned off; symptoms alone do not confirm the switch is defective.

Fitment guidance: For select electric ranges and cooktops that list part number 12002121. This is a model-specific electrical control, not a visual-match or universal-fit part. Verify the complete model and serial number, original switch number, terminal markings, shaft style, element position, and electrical rating before ordering; similar-looking switches are not interchangeable.

Technical Specifications

Service and safety note: Disconnect power at the breaker and verify power is off before service. This repair involves line-voltage wiring. Follow the appliance wiring diagram and service manual; replacement terminal positions can differ from the original. Use a qualified appliance technician if you are not experienced with electrical repairs.

How to find your model number: Check the rating plate around the oven-door frame, behind or beneath the storage drawer, on the frame after the drawer is removed, or under the cooktop. Record the complete model and serial number, then confirm the parts diagram specifies 12002121.
