How to troubleshoot your Whirlpool gas cooktop when burners aren't heating properly
When all gas burner flames are weak on the cooktop, check the gas supply shut-off valve to make sure it’s fully open. If the shut-off valve is fully open and all burner flames are weak, you may need to have your gas supplier check the gas supply pressure. If gas supply pressure is okay, a failed pressure regulator on the cooktop may be restricting flow to the burners.
If a single burner isn’t heating properly, check the burner head for a spill and clean the burner head if it’s clogged.
Common parts that sometime need replacing on Whirlpool cooktops
- 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.
- 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 switch). The radiant surface element has a limit switch that shuts off the element to protect the ceramic glass cooktop from overheating.
- 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.
- 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.
- 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.
- 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.
