Viking Range Igniter Not Working: Causes & Fix
A Viking range oven igniter that glows but never lights the burner has almost always weakened with age — it still heats up, but it no longer draws 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 has failed. Watch a…
Glows but won't light#
Viking gas ovens use a glow-bar igniter wired in series with the safety valve. The valve only opens once the igniter pulls a high enough current through the circuit, which is also what 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 amp-draw problem#
This is why a glowing igniter is not proof it is good. A healthy Viking igniter draws a strong current and reaches a bright white-orange; a tired one draws too little — down toward zero amps of useful pull — and only reaches a dim orange. On ranges such as the VGR5486G and VGSC4866Q, a technician clamps the igniter circuit to read the actual draw, which tells the story 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 rather than a homeowner repair.
What you can check#
You can safely watch the igniter through a preheat and note the glow: bright and quick with a flame is healthy, dim and slow with no flame is a failing igniter. Beyond that, testing 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 in waiting. If yours has been slow to catch or has missed a light now and then, have the igniter checked before the cooking days — a fading igniter rarely gets better 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.
