Viking Range Burner Clicking After Flame Is Lit:... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) sends a 120V AC signal to the spark module, which in turn generates a high-voltage spark to ignite the gas. Once the flame is detected by the flame sensor (thermocouple), a small DC voltage is generated and sent back to the MCU, signaling the burner is lit and deactivating the spark module. If the MCU doesn't receive this signal, or if the flame sensor is intermittent, the MCU continues to signal the spark module, resulting in continuous clicking.

Symptoms:

The Viking range burner clicks continuously even after the burner has ignited and is producing a flame. The clicking sound originates from the spark igniter near the burner.

Possible Causes:

Faulty spark module (igniter).
Incorrect gas pressure.
Dirty or corroded burner ports.
Grounding issue with the igniter.
Defective flame sensor (thermocouple).
Loose wiring connections.

Solution:

1

Disconnect power to the Viking range at the breaker panel. Lock Out/Tag Out (LOTO) procedures must be followed.
2

Visually inspect the burner ports for any debris or corrosion. Clean burner ports with a small brush or needle tool.
3

Check the spark igniter for cracks or damage. Inspect wiring for loose connections or corrosion. Tighten or replace as necessary.
4

Verify the grounding of the spark igniter to the chassis. Ensure a solid connection.
5

Test gas pressure using a manometer. Normal operating pressure is typically 4-6 inches of water column for natural gas, and 10-12 inches for propane. Adjust regulator if needed.
6

Using a multimeter, check the spark module output voltage to the igniter while the burner is lit. If voltage is present and clicking continues, replace the igniter.
7

If the problem persists, replace the spark module.

Safety Warning:

Disconnect power to the appliance at the breaker panel before attempting any repairs. Always follow Lock Out/Tag Out (LOTO) procedures. High voltage is present when the range is powered on. Gas leaks can create an explosion hazard; ensure proper ventilation and gas detection measures.

Prevention:

Regularly clean the burner assembly, including burner ports and igniter. Inspect wiring connections annually and tighten if necessary. Check gas pressure periodically.

Expert Tip:

Some Viking ranges have a service mode that allows you to manually test the spark igniter and flame sensor. Refer to the service manual for the specific sequence for your model. Often holding the bake and broil buttons simultaneously for 5 seconds will activate test mode.

Frequently Asked Questions

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

Access procedures vary. Typically, you need to remove the burner grates, burner caps, and burner bases. The spark module is often located underneath the cooktop surface, requiring its removal (after disconnecting power, of course). Refer to the service manual for detailed instructions for your specific model.

•What is the correct gas pressure for my Viking range if it's converted to propane?

Viking propane ranges typically require 10-12 inches of water column pressure at the manifold. Always verify with the model's service manual and a manometer.

•Where is the flame sensor located on my Viking range burner assembly?

The flame sensor (thermocouple) is typically located near the burner, close to the spark igniter. It's a small metal rod that sits in the flame when the burner is lit.
