Viking Cooktop Igniter Clicking Continuously After... | appliancefaults.com

Technical Background:

The Viking cooktop uses a spark module to generate a high-voltage spark at the igniter electrode. This spark ignites the gas flowing from the burner. The cooktop's MCU (Microcontroller Unit) controls the voltage path based on inputs from the surface control switches. The MCU sends a signal to the spark module to initiate the spark. If the MCU receives incorrect or continuous feedback, the sparking will continue.

Symptoms:

The Viking cooktop igniter clicks continuously after the cooktop has been cleaned. The burner may or may not light.

Possible Causes:

Moisture or cleaning residue around the burner or igniter.
Faulty spark module (ignition control module).
Damaged or shorted igniter electrode.
Cooktop surface control switch malfunction.
Loose wiring connection to the spark module or igniter.
Grounding issue within the cooktop chassis.

Solution:

1

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

Carefully inspect each burner and igniter electrode for moisture or cleaning residue. Use compressed air to thoroughly dry all components.
3

Check the igniter electrode for cracks or damage. Resistance test the igniter electrode using a multimeter. A reading of OL indicates a faulty igniter.
4

Examine the spark module for any signs of burning or damage. Locate the spark module behind the control panel, typically secured with 1/4-inch screws.
5

Test the cooktop surface control switches for continuity using a multimeter. If a switch is stuck in the 'on' position, replace it.
6

Check all wiring connections to the spark module and igniter electrodes. Ensure connections are tight and free from corrosion.
7

Reconnect power to the cooktop and test the burners. If the igniter continues to click, replace the spark module.

Safety Warning:

Disconnect power to the cooktop before performing any repairs. Lockout/Tagout (LOTO) the breaker panel to prevent accidental re-energizing. High voltage is present in the ignition system.

Prevention:

Avoid spraying cleaning solutions directly onto the cooktop surface. Instead, apply cleaner to a cloth and wipe the surface. Ensure all burner components are completely dry before using the cooktop.

Expert Tip:

Some Viking cooktops have a service mode that allows you to test the igniters individually. Consult the service manual for your specific model to access the service mode sequence. This can help pinpoint the faulty component.

Frequently Asked Questions

•How do I test the igniter electrode with a multimeter?

Set your multimeter to the ohms setting. Place one probe on the metal tip of the igniter and the other probe on the metal base. A reading close to zero ohms or a low resistance value indicates a good igniter. An open circuit (OL) indicates a faulty igniter.

•Where is the spark module located on my Viking cooktop?

The spark module is typically located behind the control panel, often near the center of the cooktop. You will need to remove the control panel to access it. Refer to your specific model's service manual for exact location and disassembly instructions.

•What is the voltage output of a functioning Viking spark module?

A functioning Viking spark module outputs a high voltage pulse, typically in the range of 2,000 to 4,000 volts AC. However, measuring this directly is difficult and not recommended due to the risk of electrical shock. Instead, focus on testing the igniter electrode and wiring.
