Viking Range Oven Burner Flame Too Small or Weak:... | appliancefaults.com

Technical Background:

Viking ranges use a gas pressure regulator to maintain a constant gas flow to the burners. The igniter or spark module creates a spark to ignite the gas. The MCU monitors the burner through a flame sensor completing a milliamp circuit back to the control board.

Symptoms:

US homeowners typically report a weak, small, or inconsistent flame on their Viking range oven burner. This can result in longer preheating times, uneven cooking, and overall reduced oven performance.

Possible Causes:

Clogged burner ports
Faulty gas pressure regulator
Incorrect gas supply pressure
Defective igniter or spark module
Partially closed gas shut-off valve
Blocked or restricted gas supply line

Solution:

1

Verify the gas supply shut-off valve is fully open. Ensure the valve is not partially closed, restricting gas flow.
2

Check the gas supply pressure using a manometer. A reading of approximately 4 inches of water column (WC) for natural gas or 10 inches WC for propane is typical.
3

Inspect the burner ports for debris or blockage. Use a small wire or burner port cleaning tool to clear any obstructions. A clogged port will result in a smaller, weaker flame.
4

Test the igniter's spark. Visually confirm a consistent spark is present at the burner during ignition. If the spark is weak or nonexistent, replace the igniter or spark module.
5

Examine the gas pressure regulator. If the flame size fluctuates significantly, the regulator may be faulty and require replacement. Disconnect power before inspecting and replacing.
6

Check for kinks or obstructions in the gas supply line. Ensure the line is properly connected and free from any restrictions that could impede gas flow.
7

Use a 1/4-inch nut driver to access and inspect the burner assembly. Look for any signs of damage or corrosion that could affect burner performance.

Safety Warning:

Lock Out/Tag Out (LOTO) the breaker before any disassembly. The range operates on 120V AC. Gas leaks are extremely dangerous, so ensure proper ventilation.

Prevention:

Regularly clean the burner ports to prevent clogging. Schedule annual licensed technician inspection to ensure proper gas pressure and regulator function.

Expert Tip:

Viking ranges have a diagnostic mode, enter the sequence by pressing bake, then broil, then bake, then broil within 5 seconds. This should display error codes on the display.

Frequently Asked Questions

•What is the correct gas pressure for my Viking range?

Typically, natural gas ranges operate around 4 inches of water column (WC), while propane ranges require approximately 10 inches of water column (WC). Consult your model's specifications for exact values.

•How do I clean the burner ports on my Viking range?

Use a small wire, needle, or a dedicated burner port cleaning tool to gently clear any debris or obstructions from the burner ports. Ensure the gas supply is off before cleaning.

•Where is the gas pressure regulator located on my Viking range?

The gas pressure regulator is usually located near the gas inlet connection at the back of the range. It's a small, round or cylindrical device with a gas line connected to it.
