Westinghouse Oven: not igniting

Professional Repair Guide

What is this symptom?

Is your Westinghouse oven not igniting? This common issue may manifest as a glowing igniter that fails to light the burner, or no glow at all. You might notice repeated ignition attempts, a faint gas smell, and inability to reach the desired temperature. Understanding the causes can help you tackle this frustrating problem effectively.

Urgency: High

Important Tips for Westinghouse Models

  • Many Westinghouse/White-Westinghouse gas ranges use a flat-style oven igniter; parts retailers list genuine OEM options such as manufacturer part number 5303935066 (example pricing around $35.83 at time of source crawl). Always match by model number.

Possible Causes

Weak or failing hot-surface oven igniter (glows but does not draw enough current to open the gas safety valve)

How to Identify: Igniter glows but burner does not light; or igniter glows for longer than ~90 seconds without ignition; may take much longer than normal to light or lights intermittently.

Part: Oven igniter (hot surface igniter / glow bar)

Failed hot-surface igniter (no glow / open circuit)

How to Identify: No igniter glow at all when BAKE/BROIL is selected; oven remains cold; multimeter continuity test shows open circuit.

Part: Oven igniter (hot surface igniter / glow bar)

Burner tube or ports clogged (food spill/grease blocking gas flow) leading to delayed ignition or no ignition

How to Identify: Igniter glows and gas smell may be present but flame does not carry across burner; ignition is delayed or uneven; visible debris/corrosion on burner ports.

Part: Oven burner / burner ports

Gas safety valve / oven gas valve not opening (electrical failure or stuck valve)

How to Identify: Igniter glows normally but no ignition and no gas odor; or igniter tests good but still no burner ignition; symptoms persist after igniter replacement.

Part: Oven safety valve / gas valve

Loose/burned wiring connection to igniter or safety valve (heat damage at connectors)

How to Identify: Intermittent ignition; visible discoloration/melted connectors; movement of harness changes behavior; igniter may not glow consistently.

Part: Igniter wiring harness / terminal connections

Igniter misalignment (igniter not positioned correctly near burner gas stream)

How to Identify: Igniter glows and gas can be heard/smelled but burner does not light until adjusted; issue may occur after recent repair or burner/igniter replacement.

Part: Igniter mounting/bracket alignment

Cooktop/surface burner ignition system failure (if the symptom refers to surface burners rather than the oven cavity)

How to Identify: Surface burner does not click/spark; other burners may or may not spark; ignition may work only when another knob is turned on; burners light with a match but not via spark.

Part: Spark electrode, spark ignition switch, spark module (surface burners)

DIY Solutions

Observe igniter behavior and apply the 90-second diagnostic (most common fix path)

Easy 5-10 minutes
  1. Set oven to BAKE and watch the igniter through the burner area (remove the bottom panel if your model allows safe viewing).
  2. If the igniter glows but the burner does not light within ~90 seconds, the igniter is likely weak and should be replaced.
  3. If the igniter does not glow at all after ~30–60 seconds, proceed to wiring/continuity checks or igniter replacement.
⚠️ Safety First: If you smell strong gas, turn the oven OFF immediately, ventilate the area, and avoid flames/sparks.

Clean oven burner ports and check for blockage (for delayed/no ignition with dirty burner)

Moderate 20-40 minutes
Tools Needed: Screwdriver, Soft brush, Vacuum (optional), Flashlight
  1. Turn off power to the range at the breaker and shut off the gas supply valve.
  2. Remove oven racks and the oven bottom panel (and flame spreader if present) to expose the burner.
  3. Inspect burner ports for grease, corrosion, or food debris; gently brush and clear ports. Avoid enlarging holes.
  4. Reassemble panels, restore gas and power, then test ignition.
⚠️ Safety First: Always shut off gas before disassembly.

Replace the hot-surface igniter (Westinghouse/White-Westinghouse common repair)

Advanced 45-90 minutes
Tools Needed: Screwdriver/nut driver, Work gloves, Wire cutters/strippers (if hardwired), Ceramic wire nuts (high-temp)
  1. Turn off power at the breaker and shut off the gas supply.
  2. Remove oven racks and the oven bottom panel to access the burner and igniter.
  3. Disconnect the igniter harness (or cut and splice using ceramic/high-temp wire nuts if your replacement includes them).
  4. Remove mounting screws, install the new igniter in the same position, and route wiring away from heat sources.
  5. Reassemble panels, restore gas and power, and test BAKE/BROIL ignition.
⚠️ Safety First: Handle the igniter carefully; the element is fragile and oils from skin can shorten life (use gloves).

Inspect and reseat igniter and valve wiring connectors (heat-damaged connections)

Moderate 20-30 minutes
Tools Needed: Screwdriver, Flashlight
  1. Turn off power at the breaker and shut off the gas supply.
  2. Access the igniter and safety valve wiring (rear panel and/or oven bottom depending on model).
  3. Check for loose terminals, corrosion, or heat discoloration; reseat connectors firmly.
  4. If connectors are melted or brittle, stop and schedule a professional repair (wiring replacement/splice may be needed).
⚠️ Safety First: Do not operate the oven with visibly damaged wiring insulation.

When to Call a Professional

You smell strong gas or suspect a gas leak at any point (turn off gas, ventilate, and seek help).
Igniter replacement does not restore ignition and the oven still does not light (possible safety valve/control issue).
You find melted/burned wiring, damaged insulation, or signs of arcing near the igniter or gas valve.
The oven ignites with a loud boom/delayed ignition repeatedly (risk of gas accumulation).
You are not comfortable shutting off gas/power or disassembling the oven cavity panels.

Preventive Maintenance

  • Clean spills promptly and periodically inspect the oven burner area for grease/debris buildup (burner ports and flame spreader).: Burner port clogs that can cause delayed ignition or failure to ignite
    Frequency: Monthly (or after major spills)
  • Avoid slamming the oven door and avoid heavy impacts that can crack the hot-surface igniter.: Premature igniter failure
    Frequency: Ongoing
  • During annual deep cleaning, visually inspect wiring near the igniter and safety valve for heat damage or looseness.: Intermittent ignition from poor electrical connections
    Frequency: Annually

Common Issues Reported by Users

  • Faulty igniter
  • Gas supply issue
  • Defective oven control board

User Suggested Solutions

  1. Inspect and clean the igniter. If it appears damaged or does not spark consistently, replace it. Ensure the oven is unplugged before performing this task.

  2. Check the gas supply line for any kinks or blockages. Ensure the gas valve is open. If there are issues with the gas supply, contact a professional.

  3. Test the oven control board for faults. If there are signs of damage or malfunction, replace the control board. This may require a multimeter to diagnose.
