Wolf Gas Range Igniter Glowing Red, No Flame:... | appliancefaults.com

Technical Background:

The Wolf gas range uses a spark igniter system. The oven control module (OCM) sends 120V AC to the igniter. As the igniter heats, it creates a current drop, signaling the OCM to open the gas valve. If the current drop doesn't occur or the gas valve doesn't open, no gas flows to the burner, preventing ignition.

Symptoms:

The homeowner observes that the igniter on their Wolf gas range is glowing red, indicating it's receiving power, but the burner is not igniting and there is no flame.

Possible Causes:

Faulty gas valve: The valve may not be opening even though the igniter is working.
Clogged burner ports: Blocked ports prevent gas from flowing to the igniter.
Defective igniter: Although glowing, the igniter may not be producing sufficient amperage to open the gas valve.
Insufficient gas pressure: Low gas pressure can prevent proper ignition.
Malfunctioning oven control module (OCM): The OCM may not be sending the correct signals to the igniter or gas valve.
Incorrect igniter gap spacing.

Solution:

1

Turn off the gas supply to the range at the shutoff valve. Use a 9/16-inch wrench.
2

Verify 120V AC power is present at the range receptacle using a multimeter.
3

Remove the burner grates and burner cap.
4

Carefully inspect the burner ports for any clogs or debris. Clean with a small wire or burner cleaning tool.
5

Check the igniter for cracks or damage. Replace if necessary.
6

If the burner ports are clear and the igniter is functional, check the gas valve solenoid for proper operation using a multimeter to check for continuity. A reading of 0 ohms typically means the solenoid is shorted and needs replacement.
7

If gas valve is good, consult the Wolf service manual to check the OCM output voltage and test the thermistor that confirms flame.

Safety Warning:

Always disconnect power to the range at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures are critical to prevent accidental electrocution. Gas leaks can cause explosions; ensure proper ventilation and leak test after any gas line work.

Prevention:

Regularly clean burner ports to prevent clogging. Annually inspect the igniter for damage. Check the gas line for leaks and corrosion using soapy water.

Expert Tip:

Many Wolf ranges have a service mode that can be accessed by pressing and holding specific buttons simultaneously. Consult the service manual for your specific model to access diagnostic codes and test functions.

Frequently Asked Questions

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

Typically, Wolf gas ranges operate at a manifold pressure of 4 inches of water column (WC) for natural gas and 10 inches WC for propane. Verify with your model's specifications.

•How do I test the gas valve solenoid?

Disconnect the wires from the gas valve solenoid. Set your multimeter to the ohms setting. Place the probes on the terminals of the solenoid. A reading of approximately 1000-1500 ohms usually indicates a good solenoid. A reading of 0 ohms or infinite ohms indicates a faulty solenoid.

•Where can I find the service manual for my Wolf range?

You can usually find the service manual on the Wolf website, through appliance parts retailers, or by contacting Wolf customer support directly. Be prepared to provide your model number.
