Understanding the Problem
What this part is: The oven igniter (hot surface igniter, HSI) is the component that heats up and allows the gas safety valve to open so the burner can light. When it fails the burner won't light or the oven takes a long time to light. Diagnostic and repair steps (numbered): 1. Confirm symptoms: oven won’t heat, no glow in oven when calling for heat, long ignition time, or repeated clicking/attempting to light. If you smell gas, stop and ventilate — do not continue diagnostics. 2. Safety first: disconnect electrical power at the breaker and shut off the gas supply before you touch any internal components. Wait for the oven to cool. 3. Access the igniter: remove oven racks, then remove the lower access panel or bottom panel inside the oven to expose the burner tube and igniter assembly (usually located at the rear or bottom center of the oven interior). 4. Visual inspection: look for a cracked, broken, discolored, or sagging ceramic/glass igniter. Igniters are fragile — if it looks damaged it needs replacement. 5. Electrical continuity test: with power off and the igniter disconnected from the harness, use a multimeter set to ohms. A healthy hot surface igniter generally shows low but not zero resistance (varies by model). If the meter reads OL (open/infinite), the igniter is failed and must be replaced. 6. Live behavior test (optional / for experienced DIYers): with the oven on bake and someone standing by (power on, DO NOT touch internal parts), the igniter should glow orange within a few seconds. If it never glows, it’s bad. If it glows but the burner never opens, the igniter may be weak (not drawing enough current) or the gas safety valve may be bad. 7. Check wiring and connector: inspect the igniter harness and connector for corrosion or loose wires. Repair or replace damaged wiring. A poor connection can mimic a bad igniter. 8. Replace the igniter: remove mounting screws that hold the igniter to the burner tube, carefully pull the igniter away (do not force or snap it), disconnect the two-wire connector. Install the new igniter by reversing removal steps — attach connector, secure mounting screws, and make sure the igniter is positioned the same distance and orientation from the burner as the old one. 9. Restore gas and power: turn on gas and restore electrical power. Run an ignition test on Bake to verify the igniter glows and the burner lights in a few seconds. 10. If new igniter glows but oven still won’t light: test/inspect the gas safety valve and the control board/relay. A new igniter that glows but fails to open the valve points to a valve or control issue. 11. Final check: after successful ignition, cycle the oven several times and confirm correct heat-up times. Check for any gas odor — if present shut off gas and call a pro. 12. Clean up and documentation: replace access panels and keep the old igniter for reference until satisfied the repair is complete. Safety note: Gas ovens present a combustion and gas-leak risk. If you smell gas at any time, stop, ventilate the area, shut off gas, and contact a qualified technician. If you are not comfortable working with gas or live circuits, hire a qualified service technician.
Common Symptoms
Oven won't light or heats extremely slowly; no glowing igniter visible when oven calls for heat; long ignition delay; repeated clicking; sometimes a faint gas smell before lighting.
Common Causes
- Failed hot surface igniter (ceramic/glass element cracked or open circuit)
- Weak igniter that glows but doesn't draw enough current to open the gas safety valve
- Damaged wiring/connector or failing gas safety valve/control board

Helpful Repair Tip
Quick confirm: with power off, disconnect the igniter and check resistance with a multimeter — an open circuit (infinite ohms) means the igniter is bad. If it glows but the burner still won’t light, the igniter is weak or the gas valve is faulty.
Frequently Asked Questions
How do I know for sure the igniter is the problem?
Start with a visual check for cracks and a continuity test with a multimeter (power off). If the igniter is open (infinite resistance) it’s dead. If it glows but the burner won’t light or it takes a long time, the igniter may be weak — replace it and retest. If a new igniter still doesn’t open the gas valve, the valve or oven control may be at fault.
Can I replace the igniter myself or should I call a technician?
Many homeowners can replace a Tappan oven igniter with basic tools and by following safety steps: shut off power and gas, remove the access panel, disconnect the two-wire connector, swap the igniter, and reassemble. However, if you detect a gas leak, smell gas, or aren’t comfortable working with gas/electricity, call a qualified appliance technician.
