Whirlpool Gas Cooktop Wooshing Sound When Lighting:... | appliancefaults.com

Technical Background:

The cooktop's electronic control module (ECM) energizes the igniter, which creates a spark near the burner port. Gas flows to the burner, and the spark ignites the gas. The ECM monitors the flame rectification signal to confirm ignition. If the air/fuel mixture is incorrect or the igniter is weak, it can cause a delayed or explosive ignition, resulting in the 'woosh' sound.

Symptoms:

US homeowner reports a loud 'woosh' sound occurring when attempting to light a burner on their Whirlpool gas cooktop.

Possible Causes:

Incorrect air/gas mixture
Dirty or misaligned burner ports
Faulty igniter
Weak or failing gas regulator
Blocked or restricted gas supply line

Solution:

1

Turn off the gas supply to the cooktop at the shut-off valve. This is usually a yellow handle near the gas connection under the cooktop.
2

Disconnect power to the cooktop at the breaker panel. Locate the appropriate breaker and switch it to the OFF position.
3

Remove burner grates and burner caps. Note their positions for reassembly.
4

Clean burner ports with a small wire or burner port cleaning tool. Ensure all ports are free of debris.
5

Inspect igniter for cracks or damage; replace if necessary. Test voltage with a multimeter; should read approximately 3.3-3.6 VDC when attempting to ignite the burner.
6

Check gas pressure with a manometer; should be between 4-6 inches of water column (WC). If outside of this range, the gas regulator may be faulty.
7

Reassemble cooktop, turn on gas supply, and test ignition. Observe flame for proper size and color (blue with slight yellow tips).

Safety Warning:

Lock Out/Tag Out (LOTO) the breaker panel before working on any electrical components. Gas is flammable and explosive. Ensure proper ventilation and use caution when working with gas lines. Call a qualified technician if you are uncomfortable working with gas appliances.

Prevention:

Regularly clean burner ports to prevent blockages. Annually inspect gas connections for leaks using a gas leak detector solution.

Expert Tip:

Many Whirlpool cooktops have a 'calibration' mode accessible via a specific button sequence (refer to the service manual). This mode can sometimes resolve minor ignition issues by automatically adjusting gas flow parameters.

Frequently Asked Questions

•What is the proper way to test the gas regulator?

Use a manometer to measure the gas pressure at the test port downstream of the regulator. The pressure should be within the range specified in the cooktop's service manual (typically 4-6 inches of water column). If the pressure is outside this range, the regulator is likely faulty and needs replacement.

•How do I identify the correct replacement igniter for my cooktop?

Locate the model number of your cooktop. Use the model number to search for the correct igniter on appliance parts websites or consult the cooktop's parts diagram. The igniter may also have a part number stamped on it.

•What type of gas leak detector solution should I use?

Use a commercially available gas leak detector solution specifically designed for detecting leaks in gas lines and fittings. These solutions typically create bubbles when applied to a leaking area. Never use soap and water, as some soaps can corrode gas lines.
