Bradford White Water Heater Igniter Not Working
The Short Answer: A Bradford White igniter that does nothing can be a dead control, open thermal safety, failed igniter, wiring fault, or missing power. A glow without ignition can be fuel, valve, vent, or flame-sensing trouble. Photograph the LED pattern, try one labeled start sequence, and stop if the fault returns.

Search Intent & The Real Problem
“Igniter” describes more than one Bradford White arrangement. Some gas tanks use a hot-surface igniter, while older or different controls use a spark electrode or a standing pilot. The LED may blink normally, indicate a lockout, or show a fault. A new igniter will not fix an open thermal switch, a blocked vent, a failed gas valve, or a wet combustion chamber.
Start with what happens after a call for heat. No LED, no click, and no glow is a power/control path. A click with no spark is electrode, lead, ground, or control. A glow with no flame moves the diagnosis toward fuel and valve. Flame that lights and drops out is flame sensing or combustion. These are different service calls.
What other guides get wrong
They tell every Bradford White owner to replace a thermocouple or “clean the igniter” without identifying the control. They also recommend holding the gas knob open through repeated failed starts. That can put unburned fuel in the chamber. The LED pattern, ignition sound, timing, and model label are more valuable than a parts list.
Step-by-Step Troubleshooting
Step 1: Identify the ignition system and record the light
| Observation | Likely branch | Safe next step |
|---|---|---|
| No status LED | Power, control, or thermal circuit | Leave it off |
| LED normal, no click or glow | Call/control/igniter circuit | Photograph and call |
| Click but no spark | Electrode, lead, ground, or board | Do not open gas fittings |
| Glow but no flame | Gas cock, valve, pressure, or igniter position | One attempt, then stop |
| Flame then immediate dropout | Flame sensing, draft, or gas control | Licensed diagnosis |
- What to look for: Exact model, gas type, LED count, whether a blower starts, whether the igniter glows, and how many seconds pass before lockout.
- Required tools: Phone and flashlight. Do not remove the sealed combustion cover.
Step 2: Check power and outside conditions
- What to look for: Power-vent cord or service switch on, breaker not tripped, exterior intake and exhaust clear, and no water from rain or a leak inside the burner compartment. A power-vent blower must start before gas ignition.
- Required tools: Eyes from outside the cabinet.
Reset a breaker or GFCI once from a dry location. If it trips again, leave it off. Do not run an extension cord or bypass the pressure switch.
Step 3: Follow the ignition sequence once
- What to look for: On a call for heat, a power-vent blower should prove first. A hot-surface igniter should glow before the valve opens. A spark model should click and spark at the electrode. No glow or spark after the safe sequence points to control power, wiring, igniter, lead, or ground.
- Required tools: Ears and eyes. Keep the cover and burner safeguards in place.
Do not touch the igniter; hot-surface elements are fragile. Do not jumper the thermal cutoff to “see if it lights.”
Step 4: Separate no ignition from no flame hold
- What to look for: Igniter works but no flame means the gas cock, gas control, pressure, or burner path needs inspection. Flame that appears and drops out means the control did not prove flame or a safety opened. Soot, yellow flame, a flame lifting out of the burner, or a bang is an immediate stop.
- Required tools: Flashlight only. No manometer or gas-fitting tools for a homeowner test.
Residential NG inlet pressure may be around 3.5–7 inches water column and LP around 10–11, but the rating plate and local installation control. Pressure and combustion tests are licensed work.
Step 5: Read the lockout before a reset
- What to look for: Bradford White LED sequence after the failed attempt, recent rain, wind, outage, filter or vent change, and whether the tank is leaking. A single reset after an obvious tripped power source may be allowed by the model label. A repeating code is the repair clue.
- Required tools: The control label, manual, and phone photo.
Water in the burner tray or a rust ring at the combustion chamber can mean the tank has failed. Do not fire it for another test.
When DIY Ends: Calling a Licensed Pro
Call for a repeated ignition lockout, failed igniter, gas odor, soot, blower or vent issue, flame rollout, wet burner, or any need to measure gas pressure or combustion. You can identify the model, clear leaves from an outside termination, and document the sequence. A licensed technician can test the igniter circuit and safety chain without defeating it.
Frequently Asked Questions
Q: Why is my Bradford White igniter not glowing? A: The unit may have no control power, an open safety, a failed igniter, broken wiring, or a control fault. Photograph the LED and ignition sequence. Do not jumper a safety or keep cycling the burner.
Q: Why does the igniter glow but the Bradford White does not light? A: The gas cock, gas control, supply pressure, burner, or ignition position may be at fault. If the glow repeats without flame, stop and call a licensed technician rather than opening a gas fitting.
Q: Can I replace a Bradford White igniter myself? A: Some igniters are replaceable parts, but the job involves combustion safeguards and model-specific wiring. If the part is not clearly accessible under the manual, or the fault repeats, use a licensed professional.
