How to Replace the Ignitor on a Sears Gas Stovetop Burner

Sears gas stovetops are equipped with four burners wired with gas ports and ignitors to light each burner individually. Over time, the electronic ignitor may wear out and no longer heat correctly to open the temperature-sensitive gas valve to light the burner. Replacing an ignitor takes less than an hour using basic tools. Buy high-temperature grease from an automotive parts store to make it easier to remove the screws.

High-temperature grease

Instructions

- 1
  Turn off the stove, and wait for it to cool.
- 2
  Close the gas valve on the back of the stove.
- 3
  Raise the top of the stove from the front with a flat-blade screwdriver. Lift the support rod inside the front of the stove to prop up the stovetop. The ignitor is a ceramic cylinder with an L-shaped metal ground plate over it. A wire runs from the ignitor to a wiring harness near the center of the stove at the top.
- 4
  Take out the two screws holding the ignitor plate in position. Due to the high heat, the screws may have fused over time into the metal plate. Use high-temperature grease around and below the screw heads to loosen the hardware, then remove the ignitor from the stove.
- 5
  Slip the wire off the ignitor by pulling the metal clip on the end, not the wire.
- 6
  Dip the threads of the mounting screws in high-temperature grease before inserting each screw through a hole in the new ignitor's mounting plate.
- 7
  Place the new ignitor in position over the mounting holes for the original ignitor.
- 8
  Tighten the screws to lock the new ignitor in place.
- 9
  Clip the wire onto the ignitor's contact.
- 10
  Lower the stovetop, and press the surface to lock it in place.
- 11
  Open the gas valve behind the appliance.
