Whirlpool Gas Cooktop Clicking Sound During Low Simmer:... | appliancefaults.com

Technical Background:

The cooktop's electronic ignition system utilizes an igniter module that generates a high-voltage spark to ignite the gas. The module relies on a flame sensor or a change in circuit voltage to confirm ignition. On low simmer, the gas flow is reduced, and any obstruction or fluctuation in gas pressure can cause the flame to extinguish, triggering the igniter to spark again. The MCU monitors voltage paths on the flame sensor circuit and adjusts spark timing based on feedback.

Symptoms:

The homeowner observes a consistent clicking sound coming from one or more burners on their Whirlpool gas cooktop when set to the low simmer setting. The flame may be flickering or extinguishing intermittently, causing the igniter to repeatedly attempt to re-ignite the burner.

Possible Causes:

Dirty burner ports causing inconsistent gas flow.
Low gas pressure affecting flame stability.
Faulty igniter module not sensing flame properly.
Incorrect simmer control setting causing flame to extinguish intermittently.
Moisture or debris affecting the spark gap of the igniter.
Worn or corroded igniter wiring.

Solution:

1

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

Disconnect the cooktop from the power outlet.
3

Remove the burner grates and burner caps.
4

Clean the burner ports using a small wire brush or a needle to remove any debris. Ensure all ports are clear.
5

Inspect the igniter for cracks or damage. Replace if necessary.
6

Check the igniter wiring for corrosion or loose connections. Repair or replace as needed. Use a multimeter to test for continuity. Replace wires if needed.
7

Reassemble the burner components, reconnect the power, and turn on the gas supply. Test the simmer setting.

Safety Warning:

Always disconnect power and gas supply before performing any repairs. Lock Out Tag Out (LOTO) procedures must be followed. Gas leaks can cause explosions and fires. Use a gas leak detector to check for leaks after any gas line work. Some components operate at 120V AC; exercise caution.

Prevention:

Regularly clean the burner caps and ports to prevent debris buildup. Check the gas pressure periodically using a manometer. Ensure the cooktop is properly ventilated.

Expert Tip:

Try using a dedicated gas line cleaner spray for stubborn blockages in the burner ports. Also, some Whirlpool cooktops have a service mode. Consult the technical sheet for the model and input the sequence. This might allow adjustment of the simmer flame height, potentially solving the issue without physical adjustments.

Frequently Asked Questions

•How do I check the gas pressure to the cooktop?

You'll need a manometer and a fitting to connect to the gas supply line. Typically, gas pressure should be around 4 inches of water column (WC) for natural gas and 10-11 inches WC for propane.

•Where can I find the tech sheet for my Whirlpool cooktop?

The tech sheet is usually located inside the cooktop, often taped to the underside of the cooktop frame or inside the control panel area. You might have to remove the burner assembly to locate it. You can also search online using the full model number.

•What is the correct spark gap for the igniter?

The spark gap is typically around 1/8 to 3/16 of an inch. Refer to the tech sheet for the exact specification for your specific Whirlpool model.
