Whirlpool Gas Range Burner Won't Light After Spill:... | appliancefaults.com

Technical Background:

The gas range uses a spark ignition system. The MCU (Microcontroller Unit) sends a signal to the spark module when a burner knob is turned on. The spark module then generates a high-voltage spark at the igniter, which ignites the gas flowing from the burner. The flame heats a flame sensor, which allows the valve to remain open.

Symptoms:

The Whirlpool gas range burner clicks but fails to ignite after a spill on the igniter. The user may smell gas intermittently or not at all.

Possible Causes:

Wet igniter
Clogged burner ports
Faulty igniter
Defective spark module
Open safety valve circuit
Loose wiring connections

Solution:

1

Turn off the gas supply to the range at the shut-off valve behind the range.
2

Unplug the range from the 120V AC outlet.
3

Remove the burner grates and burner caps.
4

Carefully remove the burner head to access the igniter.
5

Inspect the igniter for visible damage or debris. Clean it with a dry cloth or small brush.
6

Check burner ports for blockage. Use a small wire or needle to clear any obstructions. Ensure the burner is clean and dry.
7

Reassemble the burner head, cap, and grates. Plug in the range and turn on the gas supply. Test the burner ignition. If it still fails, proceed with electrical testing. With the power on and the burner knob activated, test for 120V AC at the igniter using a multimeter.

Safety Warning:

Always disconnect power to the appliance and shut off the gas supply before performing any repairs. Use proper lockout/tagout procedures to prevent accidental energization. Gas appliances involve high voltage (120V AC) and flammable gas, potentially causing electric shock, fire, or explosion.

Prevention:

Clean up spills on the range top immediately. Avoid using excessive liquid when cleaning the range. Regularly inspect burner ports for clogs and clear them as needed. Consider using burner liners to minimize spills on the burners.

Expert Tip:

Some Whirlpool ranges have a diagnostic mode. Holding the Bake and Broil buttons for 3 seconds might trigger a diagnostic mode, which can display error codes. Consult the service manual for specific procedures.

Frequently Asked Questions

•How do I test the igniter for continuity?

Disconnect the igniter from the spark module. Set your multimeter to the ohms setting. Place the probes on each of the igniter's terminals. A reading of a few hundred ohms typically indicates a good igniter. An open circuit indicates a faulty igniter.

•Where is the spark module located in my Whirlpool range?

The spark module is typically located behind the control panel or at the back of the range. You may need to remove the back panel or control panel to access it. Refer to the range's service manual for the exact location.

•What voltage should I expect to see at the igniter when the burner is turned on?

When the burner is turned on, the spark module should send approximately 120V AC to the igniter to generate a spark. Use a multimeter to measure the voltage at the igniter terminals while the burner knob is turned on.
