Viking Oven Smells Like Gas When Baking: Troubleshooting... | appliancefaults.com

Technical Background:

Viking ovens utilize a gas safety valve controlled by the Main Control Unit (MCU). The MCU sends a 120V AC signal to the igniter, which heats up and ignites the gas. Simultaneously, the MCU energizes the gas safety valve, allowing gas to flow to the burner. If the igniter fails or the valve malfunctions, unburnt gas can accumulate, causing the smell.

Symptoms:

The homeowner observes a distinct smell of gas emanating from the Viking oven when it is turned on to bake.

Possible Causes:

Gas leak at the supply line connection.
Malfunctioning oven igniter.
Faulty gas safety valve.
Improper oven calibration.
Debris or food particles burning off.

Solution:

1

Shut off the gas supply to the oven at the shut-off valve.
2

Visually inspect the gas supply line and connections for any signs of leaks or damage. Use a 12-inch pipe wrench if tightening is needed.
3

Apply a soapy water solution to the gas connections and look for bubbles, indicating a gas leak.
4

If a leak is detected, tighten the connection or replace the gas line using a 9/16-inch open-end wrench.
5

Check the oven igniter for proper operation. It should glow brightly when the oven is turned on. If it's weak, replace it using a 1/4-inch nut driver to remove mounting screws.
6

Verify the gas safety valve is opening fully when the igniter is energized. Use a multimeter to check for 120V AC at the valve terminals.
7

If the problem persists, consult a qualified gas appliance technician for further diagnosis and repair.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Lock Out / Tag Out (LOTO) procedures should be followed. Gas leaks are potentially explosive and dangerous. If you smell gas, evacuate the area and call the gas company immediately.

Prevention:

Regularly clean the oven interior to prevent food buildup. Periodically check gas connections for leaks using a soapy water solution. Schedule annual licensed technician inspection of the oven's gas components.

Expert Tip:

Many Viking ovens have a diagnostic mode accessible by pressing and holding specific buttons on the control panel for several seconds. Consult the service manual for the exact sequence for your model. This mode can provide error codes and sensor readings that can aid in troubleshooting.

Frequently Asked Questions

•What is the typical lifespan of a Viking oven igniter?

A Viking oven igniter typically lasts between 3 to 5 years, depending on usage.

•How can I determine if my oven is properly calibrated?

Use an oven thermometer to verify the internal temperature matches the set temperature. Adjust the calibration setting in the control panel if necessary. Refer to the owner's manual for calibration instructions.

•What type of soapy water solution is best for detecting gas leaks?

A mixture of dish soap and water works well. Apply it liberally to the gas connections and look for bubbles.
