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

Technical Background:

The cooktop's spark ignition system uses a spark module that receives a signal from the burner control knob switch. When the knob is pressed and turned, the switch sends a 120V AC signal to the spark module. The spark module then generates a high-voltage spark at the electrode near the burner. This spark ignites the gas flowing from the burner orifice. The cooktop clicking is a result of the spark module generating the high voltage spark. If the voltage path is incomplete or the spark module is faulty, the clicking may cease when the knob is pressed because the module or switch is making intermittent contact.

Symptoms:

The homeowner observes that the Whirlpool gas cooktop igniter clicks when the knob is turned, but the clicking stops immediately when they press down on the knob. The burner may or may not light, and the problem may affect one or more burners.

Possible Causes:

Dirty burner assembly
Faulty spark module
Weak spark electrode
Incorrect burner cap positioning
Defective gas valve switch
Wiring harness issue between the knob/switch and the spark module

Solution:

1

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

Disconnect power to the cooktop by unplugging it or switching off the breaker (LOTO).
3

Remove the burner grates and burner caps.
4

Clean the burner base and burner ports with a stiff brush or a burner cleaning tool. Ensure all ports are free from debris.
5

Check the spark electrode for cracks or damage. If damaged, replace the electrode.
6

Verify the burner cap is properly seated on the burner base.
7

Reassemble the cooktop, restore power and gas supply and test each burner. If the clicking continues, further diagnosis is needed which may involve testing the spark module for proper voltage output or the gas valve switch for continuity.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Gas appliances require careful handling. Ensure the gas supply is turned off before working on any gas components. If you are not comfortable working with gas appliances, contact a qualified technician. Lock Out/Tag Out (LOTO) procedures must be followed.

Prevention:

Regularly clean the burner assemblies to prevent debris buildup. Annually inspect the spark electrodes for damage and replace as needed. Avoid using abrasive cleaners that can damage burner components. Ensure burner caps are correctly positioned after cleaning.

Expert Tip:

To quickly test the spark module, you can use a multimeter to check for voltage output while the burner knob is turned. If no voltage is present, the spark module is likely faulty. Also, sometimes a slightly damp cloth wiped over the burner area can temporarily resolve the issue, pointing to surface contamination.

Frequently Asked Questions

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

With the cooktop unplugged and the gas supply off, set your multimeter to measure AC voltage. Then, carefully reconnect power to the cooktop and turn a burner knob to the ignition position. Probe the output terminals of the spark module (refer to the wiring diagram for location) and measure the voltage. You should see approximately 120V AC intermittently as the module attempts to spark. Be extremely careful not to touch any exposed wires or terminals while testing.

•What is the correct positioning for the burner cap?

The burner cap should sit flush and level on the burner base. Most caps have a specific orientation, often indicated by a small notch or protrusion that aligns with a corresponding feature on the burner base. Make sure the cap is not tilted or cocked to one side.

•How do I replace a spark electrode?

First, disconnect power and gas. Remove the burner grate and cap. Locate the spark electrode, it's typically held in place with a screw or clip. Remove the fastener and carefully pull the electrode straight out. Disconnect the wire connector attached to the electrode. Connect the wire to the new electrode, insert it into its mounting position, and secure it with the screw or clip. Reassemble the burner components.
