Broiler Not Igniting? Igniter or Gas Flow

What a Broiler Fault Looks Like

A slide-in range's broiler and bake mode use separate parts. The bake burner or element sits at the bottom of the oven cavity, and the broil burner or element sits at the top. A range can bake normally and still have a broiler that will not light, because the two systems are separate.

On a gas range, the broiler is a burner at the top of the cavity with its own gas valve and its own igniter. On an electric range, the broiler is an upper element that glows instead of lighting a flame. The phrase "not igniting" applies most directly to gas ranges, where a flame must appear. If your range is electric and the broiler does not glow, the question is the element, and the electric slide-in ranges guide compares those models on stated details.

Observe the Broiler From the Outside

Turn the broiler on and watch the top of the oven cavity through the oven window, or through the broiler drawer opening on a drawer design. The broiler location and power article explains how broiler placement reads on a listing.

On a gas range, the igniter should glow before gas flows. If you see a glow and no flame, the igniter is working and the question is gas flow. If you see no glow, the igniter circuit is the first question. Follow the maker's manual for what is safe to view; you do not need to open the broiler compartment for this observation.

• Does the igniter glow when you turn on broil?
• Does a flame appear after the igniter glows?
• Does bake mode still work normally?

The Igniter Is the First Question

An igniter is the part that heats until it lights the gas at the burner. On many gas range designs, the igniter also opens the gas valve as it heats. That is a general explanation; the exact sequence depends on the maker's design. A broiler that will not light often points to the igniter first.

You can read how broil appears as a mode name on a listing in the oven modes explained article, and the ignition systems article describes how ignition words read on a listing.

If the igniter does not glow, a qualified service technician can inspect the igniter, its wiring, and the control settings. The maker's installation instructions define which parts you can access safely; gas connections and valves are a technician's work.

Gas Flow Is a Separate Question

Gas flow means the gas supply reaching the broil burner. The broiler has its own burner and valve on a gas range, so gas can reach the cooktop burners and the bake burner while the broiler receives none. That is why a range that bakes fine and cooks normally on top can still fail to light its broiler.

A glowing igniter with no flame suggests a gas flow question: the supply, the valve, or the burner ports. Never adjust a gas valve or connection yourself. A qualified service technician answers those questions, and the maker's installation instructions and local codes apply. The gas cooktop deep clean article covers burner cleaning in general terms.

Maker Instructions and Official Safety Guidance

Maker range pages describe oven modes as features and do not publish repair steps on the product page. The LG range page and the Samsung range page both list oven features such as convection and air fry, which is how a reader should read a listing: a mode name is a stated feature, not a promise about cooking results. The broil vs bake article explains the mode names.

For safety, official guidance from the U.S. Fire Administration says cooking is the leading cause of home fires and that unattended equipment is the leading factor in home cooking fires. Stay in the kitchen while cooking, turn the burner off if you leave, and keep a pan lid or baking sheet nearby. Use that guidance when you run any oven mode, including the broiler.

What to Tell a Qualified Service Technician

Before calling a service technician, write down the range's model number, the series name, and what you observed when the broiler failed: does the igniter glow, does bake mode work, and when did the problem start? That information lets the technician separate the igniter question from the gas flow question. The warranty coverage article explains how warranty text reads on a listing.

If the needed repair is large and the range is old, compare a replacement on stated details instead. The slide-in range reviews page explains how the comparison works, and the gas slide-in ranges guide lists what the stated details show.

What to pick for your situation

Questions

Why does my range bake fine but the broiler will not light?

On a gas range, the bake burner and the broil burner are separate systems. Each has its own burner, valve, and igniter, so one can fail while the other works. Observe the broiler through the oven window and let a qualified service technician separate the igniter question from the gas flow question.

Should I open the broiler door to see the igniter?

Use the oven window and follow the maker's manual for what is safe to view. You do not need to open the broiler compartment yourself. If the igniter does not glow, a qualified service technician inspects the igniter and its wiring.

Can I fix a gas valve myself?

No. Gas connections and valves are work for a qualified service technician. The maker's installation instructions and local codes decide what is safe. Never adjust a gas valve without the proper training.

What does a glowing igniter with no flame tell me?

It tells you the igniter is heating, so the first question is gas flow to the broil burner: the supply, the valve, or the burner ports. A qualified service technician answers that question. The ignition systems article explains how ignition parts read on a listing.

Is a broiler mode a promise about cooking results?

No. Broil is a mode name on a listing; it tells you the range has a broiler, not how the broiler performs. Compare ranges on stated details in the buying guides.

When should I replace the range instead of repairing it?

When the needed repair is large, the range is old, or the technician cannot get parts, compare a replacement on stated details. The buying guides on this site show how the comparison works.
