Official Jenn-Air cooktop parts

Most common Sears Jenn Air parts that need replacing

1. Pressure regulator. The gas supply line for your Whirlpool cooktop connects directly to the pressure regulator. The pressure regulator is a mechanical device that reduces the incoming gas pressure to a safe and constant level for the cooktop burners.
2. Radiant surface element. The radiant surface element is mounted on the bottom of a ceramic glass cooktop and provides heat for that area of the cooktop. It's controlled by a surface element switch (also called a surface burner switch or infinite burner switch). The radiant surface element has a limit switch that shuts off the element to protect the ceramic glass cooktop from overheating.
3. Spark module. The spark module receives signals from the burner switches. When a burner control knob is in the Lite position, the spark module provides electrical current to the burner igniter electrodes and lights the surface gas burner.
4. Surface element switch. The surface element switch (also called a surface burner switch or infinite burner switch) is mounted on the control panel of an electric range or cooktop. It's an electrical switch that turns on and off the associated surface element and also controls the how much heat the element produces.
5. Spark igniter electrode. The spark igniter electrode provides an ignition spark to light a surface gas burner. It's an insulated electrode that sends a spark to the burner head when the spark module provides electrical current to the electrode. The electrode sparks with a ticking sound when you turn the control knob to the Lite position.
6. Spark igniter switch. The spark igniter switch, or surface burner igniter switch, is mounted on the burner gas valve. When activated, it sends a signal to the spark module. The spark module sends electrical current to the electrode which sparks or ticks when you turn the control knob to the Lite position.

What to do when the spark igniters keep clicking on your Jenn Air gas cooktop

A stuck burner spark igniter switch can cause a constant ticking or clicking noise on the cooktop. The igniter switches can get wet and short out when you clean the cooktop with water, and the ticking sometimes stops once the switches dry. If the spark igniter still won't stop clicking after the switches are completely dry, replace the failed burner switch.

Some gas cooktops have a spark module that reignites the burner if a burner flame goes out with that burner’s gas valve still open. If your cooktop has this type of burner reignition system and the igniters click constantly with all active burner flames lit, you may need to replace the spark module because it isn’t detecting the burner flames properly or a reignition relay on the spark module is stuck.
