Gas Oven Igniter Not Working

Igniter Not Working

The oven igniter on a gas range does two jobs at once: it gets hot enough to light the burner, and it draws enough electrical current in the process to signal the gas valve to open. A weak igniter can fail at either job -- it may glow but never get hot enough to open the valve, so gas never flows and the oven never lights.

Never test an igniter with the gas supply on. Diagnosis should be visual: with the gas shut off, watch whether the igniter glows brightly within the first 30-90 seconds when the oven calls for heat, or have a licensed technician check the live circuit if you are not confident doing this yourself.

A simple comparison helps here: if you have seen the oven light normally in the past, compare how long the igniter now takes to reach full brightness against how it used to behave. An igniter that has gradually gotten slower over weeks or months is a classic sign of a weakening element, while one that stopped working overnight points more toward a connector or power-supply issue upstream of the igniter itself.

Safety first: ranges and ovens combine electricity, gas, and extreme heat.

  • Shut off power at the breaker before removing any panel, testing a switch, or touching internal wiring -- don't rely on the range's own power or oven control being off.
  • On a GAS range, shut off the gas supply at the shutoff valve before working near the burners, igniter, or gas valve. Never test an igniter, spark electrode, or gas valve with gas flowing to the appliance.
  • If you smell gas at any point, leave immediately and call your gas utility from outside the house -- do not flip switches, light anything, or try to troubleshoot the smell yourself.
  • The oven cavity, bake and broil elements, and stovetop burners stay dangerously hot long after use -- let the range cool completely before opening it up or reaching inside.
  • Gas line connections and gas valve work require a licensed technician. Do not attempt to disconnect, repair, or replace a gas line or gas valve yourself.

Most Likely Causes

Work through these from most to least common -- most range and oven repairs turn out to be one of the first two or three parts on this list, not the last.

  1. Igniter weakened or cracked — a healthy igniter glows bright orange-white; a weak one glows dull orange, takes noticeably longer, or never gets hot enough to open the valve. Part type: Frigidaire Range Oven Burner Igniter 5303935066 (5303935066) or Tappan Range Oven Burner Igniter 316489403 (316489403).
  2. Igniter draws current but not enough to open the valve — igniters and gas valves work as a matched circuit -- an igniter that looks "almost fine" visually can still fail to draw enough amperage to trip the valve open, so gas never flows even though the igniter appears to glow.
  3. Low or incorrect gas pressure at the regulator — starves the burner even with a good igniter. Part type: Range Pressure Regulator (316091706).
  4. Wiring or terminal block connection to the igniter circuit — Part type: Terminal Block (5303935061).
  5. Control board not sending the ignition signal at all — least common -- the igniter never glows whatsoever. Check this last, after confirming voltage is present at the igniter terminals.

How to Confirm Before You Buy a Part

Before ordering any replacement part, take a minute to confirm the fit -- it is the difference between a repair that works the first time and a part that does not match.

  1. Find the model/serial plate. On most ranges it is behind the storage drawer or kick panel at the bottom front, inside the oven door frame, or on the back panel of the unit. See how to find your model number for exact locations by appliance type.
  2. Read the full model number exactly as printed, including letters and dashes -- manufacturers often reuse near-identical model numbers across different production runs that take different parts.
  3. Verify the part fits that exact model using the model and part lookup tool before ordering, rather than assuming a part fits because it looks the same as the one you are replacing.

The full model number matters more than the brand and body style alone: one range body design is often sold under many model numbers over several years, with the exact igniter, element, switch, or control board changing partway through that run. Two ranges that look identical side by side can still take different parts if their model numbers differ, even by a single trailing letter or digit.

When to Call a Licensed Technician

Most of the parts above are within reach of a confident DIY repair using basic hand tools and a multimeter. Two situations are the exception. First, anything that requires opening a sealed gas valve, running a new gas line, or repairing a suspected gas leak is technician-only work -- these repairs need pressure testing and code-compliant fittings that are not a basic-tool job, and a mistake here is a safety hazard, not just a wasted part. Second, if you have already replaced the most likely part from the list above and the symptom persists, or a fault code keeps returning after a full power reset, a licensed technician with brand-specific diagnostic tools can usually isolate the remaining possibilities faster than continuing to swap parts by trial and error.

Check Your Exact Model

Part numbers above cover common range and oven platforms, but the only way to be certain a part fits your range is to look it up by model number with the model and part lookup tool. A few real range models with parts already indexed:
