How to Replace a Gas Dryer Gas Valve Coil Set
Replace the gas dryer gas valve coil set when the igniter glows but the burner does not light reliably, or the dryer heats once and then stops heating as it runs.
This is a moderate repair because you will open the dryer cabinet and work near the gas burner assembly. The job is usually straightforward if you unplug the dryer, shut off the gas supply, and swap the coils one at a time so the wiring and brackets go back the same way.
Before you start: Match your dryer's model number and compare the coil count, bracket style, and wire connector layout before ordering.
Safety first
- Unplug the dryer before opening any panels.
- Shut off the gas supply before working near the burner assembly.
- Wear gloves because dryer cabinet edges are often sharp.
- Do not pull wire connectors by the wires.
- If you smell gas at any point, stop, shut the gas off, and do not run the dryer until the leak is resolved.

Step-by-step fix
Step 1: Confirm the coil set is the likely problem
- Run the dryer on a heated cycle and listen near the lower front or rear service area, depending on your dryer design.
- Watch for a normal-looking igniter glow without a steady flame, or a flame that appears once early in the cycle and then stops returning.
- Notice whether the drum tumbles normally and airflow seems strong at the exhaust. Weak airflow can cause overheating and shut the burner down for other reasons.
- Unplug the dryer and let it cool before opening anything.
If it works: The symptoms point to weak gas valve coils rather than a no-power or no-airflow problem.
If it doesn’t: If the igniter never glows, the dryer will not start, or airflow is poor, this is probably not the right repair path. Check the thermal fuse, igniter, flame sensor, or vent restriction first.
Stop if:
- You smell gas before starting the repair.
- The dryer has obvious burnt wiring, melted connectors, or heat damage around the burner area.
Step 2: Shut off power and gas, then open the burner access area
- Unplug the dryer from the outlet.
- Turn off the gas supply valve to the dryer.
- Pull the dryer out enough to work safely and avoid crushing the gas connector or vent.
- Remove the lower front panel, front panel, or rear access panel as needed to reach the burner assembly. Keep screws organized.
- Use a flashlight to locate the gas valve on the burner assembly. The coil set sits on top of the gas valve body under a small bracket or retaining clip.
If it works: You can clearly reach the gas valve and coil set with the dryer safely disconnected.
If it doesn’t: If you cannot access the burner area without forcing panels or disconnecting parts you cannot identify, look up your model's panel removal layout before continuing.
Stop if:
- The gas shutoff valve will not fully close.
- The flexible gas connector is damaged, kinked, or leaking.
- You find heavy rust, rodent damage, or scorched insulation inside the cabinet.
Step 3: Remove the old coil set
- Take a clear photo of the coil area so you can match the wire positions and bracket orientation during reassembly.
- Disconnect the wire plugs from the coils by pulling on the connectors, not the wires.
- Remove the bracket screw or retaining clip that holds the coils in place.
- Lift the coils straight up off the gas valve stems. If there are spacers or sleeves, note exactly where they sit.
- Set the old parts aside in the same order they came off.
If it works: The old coils are off and you know how the new parts need to sit on the valve.
If it doesn’t: If a connector is stuck, wiggle it gently with needle-nose pliers on the connector body. Do not yank the wires.
Stop if:
- A valve stem is bent, cracked, or loose.
- A wire terminal breaks off or the harness insulation crumbles when touched.
Step 4: Install the new gas valve coil set
- Compare the new coil set to the old one before installing. Match the height, openings, and connector style.
- Place any spacer or sleeve back onto the correct valve stem if your dryer uses one.
- Set the new coils onto the valve stems in the same positions as the originals.
- Reinstall the retaining bracket or clip and tighten the fastener snugly without over-tightening.
- Reconnect the wire plugs so each connector seats fully and follows the same routing as before, away from hot or moving parts.
If it works: The new coil set is seated flat, secured by the bracket, and fully reconnected.
If it doesn’t: If the new parts do not sit down properly or the connectors do not match, stop and verify the replacement by model number before reassembling the dryer.
Stop if:
- The replacement coil set does not match the original valve layout.
- Any wire now rests against the burner tube, igniter area, or drum path.
Step 5: Reassemble the dryer and restore service
- Reinstall any burner cover and the access or front panel you removed.
- Move the dryer back carefully without crushing the vent or gas connector.
- Turn the gas supply back on.
- Plug the dryer back in.
- If you disconnected or disturbed the gas connector, check for leaks with a proper leak-check method before running the dryer.
If it works: The dryer is back together and ready for a live heat test.
If it doesn’t: If a panel will not sit flat, reopen the cabinet and check for a misplaced screw, wire, or bracket.
Stop if:
- You smell gas after turning the supply back on.
- A leak check shows bubbling or any sign of leakage.
Step 6: Test burner operation through a full heating cycle
- Start the dryer on a heated cycle with a small damp load or a timed heat setting.
- Watch and listen through the first few burner calls if you can safely view the burner area through the access opening or inspection hole provided by your dryer design.
- Confirm the igniter glows and the burner lights cleanly, then cycles off and back on again later in the run.
- Let the dryer run long enough to confirm it keeps reheating instead of heating only once.
- Check that clothes begin drying normally and the exhaust airflow remains strong.
If it works: The burner lights reliably through repeated cycles and the dryer heats normally again.
If it doesn’t: If the igniter still glows without flame, or the dryer still loses heat after the first cycle, the problem may also involve the flame sensor, igniter, gas supply, high-limit controls, or restricted venting.
Stop if:
- The burner flames look unstable, roll out, or behave abnormally.
- The dryer overheats, shuts down, or gives off a burning smell during the test.

FAQ
What are the signs of a bad gas dryer gas valve coil set?
The most common sign is an igniter that glows but no flame appears, or a dryer that heats once and then stops heating until it cools down. Weak coils often fail after they warm up.
Do I need to replace both coils together?
Yes. Coil sets are meant to be replaced together because one weak coil can cause the same no-heat symptom and the parts wear as a pair.
Can I replace the coil set without disconnecting the gas line?
Usually yes. On many dryers you can reach the burner assembly by removing an access panel while leaving the gas connector attached. You still need to shut off the gas supply before working.
Why did my dryer still not heat after I replaced the coil set?
If the new coils are installed correctly, the no-heat problem may be caused by the igniter, flame sensor, thermal fuse, high-limit thermostat, gas supply issue, or a badly restricted vent.
How long does this repair usually take?
For a first-time homeowner, it often takes about 30 to 90 minutes depending on how easily your dryer opens and how accessible the burner assembly is.
