Viking Range Ignition Clicking But Won't Catch Flame:... | appliancefaults.com

Technical Background:

Viking ranges use a spark ignition system. The spark module sends high voltage to the igniter, which generates a spark near the burner ports. This spark ignites the gas flowing from the burner. The MCU (Main Control Unit) controls the spark module based on the burner knob position. A faulty igniter, spark module, or gas supply can disrupt this process.

Symptoms:

The homeowner observes that when a burner knob is turned on, the igniter clicks rapidly, but the burner fails to light. There is no flame, even after several attempts. The clicking sound is present, indicating the igniter is receiving power and attempting to create a spark.

Possible Causes:

Clogged burner ports
Faulty igniter
Defective spark module
Gas supply issue
Incorrect burner assembly
Grounding problem

Solution:

1

Turn off the range at the breaker panel (LOTO - Lock Out Tag Out).
2

Remove burner grates and burner caps. Inspect burner ports for clogs. Use a small wire or burner cleaning tool to clear any obstructions.
3

Check the igniter for continuity using a multimeter. A healthy igniter should show a resistance reading. An open circuit indicates a faulty igniter. Replace if necessary.
4

Verify proper gas supply to the range. Check the gas shut-off valve is fully open. If using propane, ensure the tank is not empty and the regulator is functioning correctly.
5

Inspect the spark module for visible damage. Use a multimeter to test the spark module's output voltage (usually around 2-4 kV AC) during ignition. If no voltage, replace the spark module.
6

Confirm proper grounding of the range. Check the ground wire connection at the back of the range and the ground screw on the chassis.
7

Reassemble the burner components. Turn the range back on at the breaker and test each burner for proper ignition.

Safety Warning:

Disconnect power to the range at the breaker panel before performing any repairs. Gas leaks can cause explosions. If you smell gas, immediately evacuate the area and call your local gas company or fire department. High voltage is present in the ignition system; avoid contact with the igniter or spark module while the range is powered on.

Prevention:

Regularly clean burner caps and ports to prevent clogs. Ensure proper ventilation around the range. Schedule annual licensed technician maintenance to inspect and clean the gas lines and burner components.

Expert Tip:

Some Viking ranges have a service mode that allows you to manually test the ignition system. Consult the service manual for the specific key sequence to activate the service mode.

Frequently Asked Questions

•How do I test the igniter with a multimeter?

Set your multimeter to the ohms setting (resistance). Disconnect the igniter from the spark module. Place one probe on each terminal of the igniter. A reading between 50-200 ohms typically indicates a good igniter. An open circuit (OL) indicates a faulty igniter.

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

The spark module is usually located at the back of the range, behind the control panel. You may need to remove the back panel to access it. Refer to the service manual for your specific model for the exact location.

•How do I safely check for a gas leak?

Mix a solution of equal parts dish soap and water. Apply the solution to gas connections, such as the gas shut-off valve, gas regulator, and burner connections. If bubbles form, this indicates a gas leak. Immediately turn off the gas supply and contact a qualified technician to repair the leak. Never use a flame to check for gas leaks.
