Wolf Range Igniter Not Working: Causes & Fix
A Wolf range oven igniter that glows but never lights the burner has almost always weakened with age — the flat glow-bar igniter still heats up, but it no longer pulls enough current to open the gas safety valve, so no gas is released. The igniter is a wear part and is the usual fix. Less often the safety valve itself…
Why a glowing igniter still fails#
Wolf gas ovens wire a flat glow-bar igniter in series with the safety valve. The valve only opens once the igniter draws a high enough current through that circuit, which also proves the igniter is hot enough to light gas safely. As the igniter ages its element degrades and its current draw falls, so it can glow a dull orange while never drawing enough to release gas.
The current tells the truth#
This is why glowing is not proof the igniter is good. A healthy Wolf igniter draws a strong current and reaches a bright white-orange within a minute; a tired one pulls only a few amps and reaches a dim orange without lighting. On DF486G and GR486G ranges, a technician clamps the igniter circuit to read the actual draw, which shows what a visual check cannot.

The safety valve#
If a new igniter draws proper current and the burner still will not light, attention turns to the gas safety valve. A valve that no longer opens even with adequate current is the less common but real second cause, and it is replaced as a unit. Both parts sit in the gas path, so this is technician work.
What you can check#
You can safely watch the igniter through a preheat: bright and quick with a flame is healthy, dim and slow with no flame is a failing igniter. Beyond that, measuring current draw and working on the gas valve belongs with a technician.
Safety First — Know the Risks
Gas ovens involve live gas lines — a loose connection creates explosion and carbon monoxide risk. Electric ovens run on 240V circuits. Our techs are licensed and insured — let them handle the risk.

Before the holiday cooking season#
A range oven that will not light is a holiday-meal disaster waiting to happen. If yours has been slow to catch or missed a light now and then, have the igniter checked before the cooking days, since a fading flat igniter rarely recovers on its own. If it glows but will not light, book a visit and a technician will measure the draw and replace the igniter or valve.
