Whirlpool Cooktop Clicking Noise When One Burner Is On:... | appliancefaults.com

Technical Background:

Whirlpool cooktops use a spark ignition system. When a burner knob is turned on, the burner switch signals the main control unit (MCU). The MCU then sends a low-voltage signal to the spark module. The spark module generates a high-voltage spark that jumps across the igniter to the burner, igniting the gas. The clicking sound is the sound of the spark being generated. Issues arise when the spark can't consistently reach the burner or if the module is malfunctioning.

Symptoms:

The homeowner observes a rapid clicking or ticking sound originating from a single burner only when that burner's control knob is turned on. The burner may or may not light. The other burners function normally.

Possible Causes:

Faulty spark module.
Damaged or dirty burner igniter.
Loose wiring connection to the igniter or spark module.
Cracked or wet burner cap.
Cooktop surface is wet or has food debris interfering with the spark.
Issue with the burner switch on the control board.

Solution:

1

Disconnect power to the cooktop at the breaker panel. Verify 0V AC at the cooktop receptacle with a multimeter.
2

Remove the burner grate and burner cap from the affected burner.
3

Inspect the burner igniter for cracks, damage, or debris. Clean the igniter with a dry cloth or a soft brush.
4

Check the wiring connections to the igniter and spark module. Ensure they are secure and free from corrosion. Use a 1/4-inch nut driver to tighten loose connections.
5

Test the spark module by swapping it with another module (if applicable) to see if the problem moves to a different burner.
6

If the issue persists, test the igniter for continuity using a multimeter. A lack of continuity indicates a failed igniter.
7

Replace the faulty spark module or igniter as needed.

Safety Warning:

Always disconnect power to the cooktop at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization. Cooktops operate on 120V AC; improper handling can result in electric shock.

Prevention:

Regularly clean the cooktop surface and burner caps to prevent food debris from interfering with the ignition system. Ensure the area around the igniters is dry. Avoid spills around the burner area.

Expert Tip:

Some Whirlpool cooktops have a diagnostic mode. To access it, press and hold the 'Timer' button for 5 seconds. This may display error codes or allow component testing.

Frequently Asked Questions

•How do I test the spark module with a multimeter?

While you can't directly test the spark output with a multimeter, you can check for proper voltage input to the module. Refer to the wiring diagram for the specific voltage requirements, typically 120V AC. Also, check the continuity of the input and output circuits to the igniters.

•Where can I find replacement parts for my Whirlpool cooktop?

You can find replacement parts at authorized Whirlpool parts dealers, online appliance parts retailers like AppliancePartsPros or RepairClinic, or directly from Whirlpool's website.

•What is the proper gap for the igniter to the burner?

The igniter should be positioned close to the burner port. Typically, it should be approximately 1/8 to 1/4 inch away. Refer to the specific service manual for your cooktop model for precise measurements.
