Whirlpool Gas Cooktop Clicking Stops When Knob is... | appliancefaults.com

Technical Background:

When a burner knob is pressed and turned to the 'light' position, the infinite switch sends a signal to the spark module. The spark module then generates a high-voltage pulse that is sent to the igniter(s). This high-voltage spark ignites the gas flowing from the burner. If the spark module doesn't receive the correct signal or if there is a fault in the igniter circuit, the clicking may stop prematurely.

Symptoms:

The homeowner observes that the igniter on their Whirlpool gas cooktop clicks when a burner knob is pressed, but the clicking stops before the burner ignites. The gas may or may not be flowing.

Possible Causes:

Defective spark module
Faulty igniter(s)
Open or shorted wire harness to igniter(s)
Damaged or wet burner cap
Incorrect gas pressure
Defective infinite switch

Solution:

1

Disconnect power to the cooktop at the breaker panel.
2

Visually inspect all igniters for cracks or damage. Replace any damaged igniters.
3

Inspect the wire harness connections to each igniter and the spark module for loose or corroded connections. Repair as needed. Use a 1/4-inch nut driver to remove any covers.
4

Using a multimeter, test the resistance of each igniter. An open or shorted igniter should be replaced. Typical resistance should be between 1000-2000 ohms.
5

Verify the gas supply pressure is within the manufacturer's specifications (typically 4-6 inches of water column). A manometer can be used to check this.
6

Replace the spark module if all igniters and wiring are confirmed to be good. The spark module can be located by tracing the igniter wires back into the appliance.
7

Reconnect power to the cooktop and test the burners.

Safety Warning:

Disconnect power to the cooktop at the breaker panel before performing any repairs. Lock Out Tag Out (LOTO) procedures should be followed. Gas appliances can be dangerous. If you are not comfortable working with gas appliances, contact a qualified technician. Incorrect voltage testing can result in electric shock. Only use a calibrated multimeter.

Prevention:

Regularly clean the burner caps and igniters with a damp cloth to remove food debris and spills. Avoid using abrasive cleaners that can damage the igniters.

Expert Tip:

Sometimes, the cooktop surface around the burner can be damp. Use a hairdryer on a low setting to thoroughly dry the burner assembly. This is a common quick fix.

Frequently Asked Questions

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

Testing the spark module requires specialized equipment to simulate the input signals. It's generally recommended to replace the spark module if other components have been ruled out.

•Where is the spark module located on my Whirlpool gas cooktop?

The spark module is typically located underneath the cooktop surface, often near the front or back. You'll likely need to remove the cooktop from the countertop to access it. Disconnect power first.

•What is the correct gas pressure for my Whirlpool gas cooktop?

The correct gas pressure is typically 4-6 inches of water column for natural gas and 10-12 inches of water column for propane. Refer to the model's service manual for exact specifications.
