Viking Range Igniter Clicking, Burner Won't Light:... | appliancefaults.com

Technical Background:

The Viking range's Main Control Unit (MCU) sends 120V AC to the spark module. This module then generates a high-voltage spark at the igniter tip. Simultaneously, the gas valve opens, allowing gas to flow to the burner. If the spark is insufficient or the gas flow is blocked, ignition fails. The MCU monitors feedback.

Symptoms:

The igniter on your Viking range is clicking repeatedly when you turn the burner knob, but the gas burner doesn't light. You may smell gas faintly or not at all.

Possible Causes:

Clogged burner ports preventing gas flow.
Weak or failing igniter not generating enough spark.
Faulty gas pressure regulator.
Defective spark module.
Issues with the gas supply to the range.
Loose wiring connection to the igniter or spark module.

Solution:

1

Turn off the breaker to the Viking range in the breaker panel.
2

Remove the burner grate and burner cap. Note the position of the burner cap for correct reassembly.
3

Inspect burner ports for debris. Clean with a small wire brush or a needle to clear any obstructions. Pay close attention to any ports near the igniter.
4

Check the igniter for cracks or damage. The ceramic insulator should be intact. A broken or cracked igniter will not function properly.
5

Using a multimeter, test the igniter for continuity. A good igniter should show some resistance (typically around 40-400 ohms). If there's no continuity, the igniter is faulty.
6

Verify the gas supply to the range. Ensure the gas shut-off valve is fully open. Check the flexible gas line for kinks or damage.
7

If the igniter is visibly damaged or has no continuity, replace it. Viking range igniters typically require a 5/16-inch nut driver or socket for removal and system. Reassemble components and test.

Safety Warning:

Lock Out/Tag Out (LOTO) the breaker before working on the range. High voltage is present when the range is operating. Gas leaks can be dangerous. If you smell a strong gas odor, evacuate the area and call your local gas company.

Prevention:

Regularly clean the burner grates and caps. Occasionally check the burner ports for clogs. Avoid spills on the burners that can cause buildup.

Expert Tip:

Some Viking ranges have a diagnostic mode. While model-specific, it often involves pressing and holding two buttons simultaneously for several seconds. This mode can display error codes that pinpoint the issue. Consult your service manual.

Frequently Asked Questions

•What is the proper gas pressure for a Viking range?

Typically, natural gas pressure should be around 4 inches of water column, and propane should be around 10 inches of water column. A manometer is used to measure gas pressure at the regulator.

•How do I test the spark module on my Viking range?

With the power off and safely discharged, test the continuity of the input and output terminals of the spark module. You can also visually inspect it for burn marks or damage. Replacement is often the simplest solution if suspected.

•Where can I find the model number on my Viking range?

The model number is typically located inside the oven door frame, on a metal tag or sticker, or on the back panel of the range.
