How to replace a Whirlpool dryer igniter?
For Whirlpool model LGR5636EQ3, replacing the gas dryer igniter is a straightforward repair: we disconnect power and gas, open the cabinet, remove the burner assembly cover, swap in the new igniter, then reassemble and test heat. Handle the igniter carefully because it’s fragile.
Safety first (gas dryer)
- Unplug the dryer (or switch off the breaker).
- Shut off the gas supply valve to the dryer.
- Work in a well-ventilated area; stop if you smell gas.
- Avoid touching the igniter tip with bare fingers; oils can shorten igniter life.
- If you’re not comfortable working around gas, we recommend using a qualified technician.
Steps to replace the igniter
- Remove the lint screen and any screws that secure the top (varies by design); lift the top.
- Remove the front panel (and drum if needed for access).
- Locate the burner assembly at the bottom; remove the burner cover.
- Disconnect the igniter wire harness.
- Remove the igniter mounting screw(s) and transfer the new igniter into position.
- Reinstall the burner cover, reassemble the cabinet, restore gas and power.
- Run a timed heat cycle and confirm ignition and steady flame.
Parts that commonly get checked at the same time
If the igniter glows but the burner does not light, we typically check these next:
- Dryer valve coil kit 279834 (weak coils can prevent the gas valve from opening)
- Dryer radiant sensor WP338906 (failed sensor can stop gas from opening)
- Gas valve 279923 (less common, but possible)
Quick symptom guide
| What you see | Most likely cause | What we do next |
|---|---|---|
| No glow from igniter | Igniter open, thermal safety open, wiring issue | Test igniter continuity; inspect wiring |
| Igniter glows, no flame | Coils or radiant sensor | Check coils and sensor |
| Lights once, then won’t relight | Coils overheating/weak | Replace coil kit |
Why it matters
A working igniter is required for safe, reliable heat. Replacing a weak igniter (and addressing coils or sensor issues when needed) restores normal drying times and helps prevent repeated no-heat calls.

Why is the igniter not working on my Whirlpool dryer?
On Whirlpool dryer model LGR5636EQ3, an igniter that will not glow or will not light the burner is usually caused by a failed igniter, weak gas valve coils, an open high-limit safety device, or a power or airflow issue that prevents the burner circuit from staying energized. Start with the most common, easiest checks first.
Quick checks (fastest wins)
- Confirm the dryer is set to a heated cycle (not Air Fluff or No Heat).
- Clean the lint screen and make sure the exhaust vent is not crushed or clogged.
- Listen for the burner sequence: motor running, then a click, then igniter glow (if you never get glow, focus on power and safeties).
- Inspect wiring at the igniter and burner assembly for loose spades, heat damage, or broken wires.
- If the igniter glows but the flame never starts (or starts then quits), suspect the gas valve coils.
Most common causes and what they look like
| What you observe | Most likely cause | What to do next |
|---|---|---|
| No glow at all | Open safety device or no power to igniter | Check high-limit device and wiring; verify voltage to igniter during heat call |
| Glows, no flame | Weak coils | Replace dryer valve coil kit 279834 |
| Glows, flame starts then stops after a short time | Coils failing when hot | Replace dryer valve coil kit 279834 |
| Igniter is cracked/white spot, tests open | Failed igniter | Replace igniter 279311 |
Step-by-step troubleshooting (safe, practical order)
- Unplug the dryer and shut off the gas before accessing the burner area.
- Check airflow first: poor venting can overheat the burner area and trip safety devices.
- Inspect the igniter for cracks or burn marks; test it for continuity. If open, replace igniter 279311.
- Check the high-limit safety: if it is open, the igniter often will not energize. Many repairs use the dryer high-limit thermostat W11050897 kit.
- If the igniter glows but no flame, replace the coils using dryer valve coil kit 279834.
- If heat is still inconsistent, check the operating thermostat and burner sensor; a failed thermostat can interrupt the heat circuit (example part: dryer operating thermostat WP3387134).
Why it matters
The igniter circuit depends on correct airflow and working safety controls. Fixing the root cause (often vent restriction or weak coils) prevents repeat no-heat symptoms and helps the dryer heat consistently without overheating.

How do I find the model number on my LGR5636EQ3?
Your Whirlpool dryer’s model number is printed on the appliance’s rating label. On LGR5636EQ3 dryers, that label is typically found around the door opening or on the door frame area; once you locate it, match the full model number exactly to ensure you get the right parts.
Where to look on a Whirlpool gas dryer
Check these common label locations first:
- Door jamb (the frame you see when you open the door)
- Inside the door opening on the front panel
- On the dryer door itself (edge or inner surface)
- Behind the lower front access panel (if your unit has one)
- Rear panel label (less common, but possible)
What to write down (so parts fit)
Record the full identification details from the label:
- Model number (example: LGR5636EQ3)
- Serial number (helps confirm production run)
- Type of fuel (gas) and any code letters after the model
- Any option codes shown near the model/serial
Quick checklist
| Label item | Why it matters |
|---|---|
| Model number | Matches diagrams and part compatibility |
| Serial number | Helps confirm version changes within the same model |
| Gas type info | Helps avoid ordering the wrong gas components |
If the label is missing or unreadable
Use these practical workarounds:
- Look for the model number on your purchase paperwork or service receipt
- Compare your dryer’s configuration to parts diagrams, then confirm with a common wear part like the drum belt 341241
- If you still cannot confirm it, contact Sears PartsDirect support with photos of the label area and the dryer
Why it matters
Whirlpool dryers can share similar cabinets across multiple models, but internal parts like the motor, igniter, and thermostats can vary. Using the exact model number helps us match the correct replacement parts the first time.
