Maytag Dryer Igniter Replacement Guide

A gas dryer makes heat by lighting a burner, and the igniter is what lights it. The glow-bar igniter heats until it is white-hot, a sensor confirms it is hot enough, and only then do the gas valve coils open to release gas across the glowing bar. That handshake between igniter, sensor, and coils is where gas-heat repairs live, so understanding the sequence is half the diagnosis.

How the Gas Heat System Works#

• The igniter is a brittle silicon carbide glow bar. Current heats it until it glows bright orange.
• The flame or radiant sensor watches the igniter and, once it reaches temperature, tells the control the burner is ready.
• The gas valve coils — a booster coil and a hold coil — then energize to open the valve so gas flows and lights.
• The thermal fuse and high-limit thermostat sit in series; if the dryer overheats from a blocked vent, they cut the heat circuit entirely.

Symptoms and What They Point To#

• The dryer runs and tumbles but the air stays cold — a heat-circuit fault somewhere in the chain
• The igniter glows brightly, then goes out with no flame — the gas valve coils are weak and not opening the valve
• The igniter never glows at all — a cracked igniter, or a blown thermal fuse cutting the circuit upstream
• The burner lights briefly, then drops out repeatedly — a failing sensor or marginal coils
• Long dry times paired with a tripped thermal fuse — usually a blocked vent, not the igniter

Diagnose Before You Buy#

Watch one cycle through the burner-access port. If the igniter glows and the flame never comes, order the coils, not the igniter. If nothing glows, test the igniter for continuity with a multimeter — a good silicon carbide igniter reads a defined resistance, and an open reading means it has cracked. Also test the thermal fuse for continuity, since a blown fuse produces a no-glow, no-heat symptom identical to a dead igniter. Never replace a blown thermal fuse without clearing the blocked vent that blew it.

Step-by-Step Replacement#

1. Unplug the gas dryer — it uses a 120-volt outlet — and shut off the gas supply valve.
2. Open the cabinet per your model to expose the burner assembly at the base.
3. For the igniter, release its single mounting screw and connector. Handle the new igniter by its ceramic base only — never touch the flat silicon carbide element, since skin oil creates hot spots that crack it early.
4. For the coils, unscrew the coil retainer, slip the old booster and hold coils off the valve, and fit the new set, reconnecting each lead in its place.
5. Seat the igniter so it sits just under the burner ports, reconnect everything, and refit the cabinet.
6. Restore gas and power, then run a heated cycle and confirm the igniter glows, the flame lights within a minute, and the burner cycles steadily.

Tools You Will Need#

• A nut driver and screwdriver for the cabinet and burner assembly
• A multimeter for igniter and thermal-fuse continuity
• A gas-leak detector spray to check the valve connections after reassembly

Common Mistakes to Avoid#

• Touching the silicon carbide element with bare fingers, which cracks it prematurely.
• Replacing the igniter when it glows fine but no flame follows — that symptom is the coils, not the igniter.
• Fitting a new thermal fuse without clearing the blocked vent that blew it, so it blows again.
• Ignoring the gas shutoff, which must be closed before opening the burner.

What Happens If You Delay#

A no-heat gas dryer is out of service, but running it with a marginal igniter or weak coils is worse. Repeated failed light attempts let small puffs of unburned gas into the drum before the valve closes, and a dryer nursed along on a blocked vent that keeps blowing the thermal fuse is a genuine fire risk from lint overheating. Fix the heat system and clear the vent promptly rather than living with intermittent heat.

Repair or Replace the Dryer#

The igniter and coils are inexpensive parts, so replacing them is well worth it on a sound Maytag. Only consider a new machine if the motor or drum has also failed on an old unit.

What It Costs#

There is no single published price — the igniter and coils are modest parts, and most of any professional charge is diagnosis and labor to open the cabinet. Because the parts are cheap and the fault is testable, this is a strong DIY value for anyone comfortable working near a gas line. Match the parts to your model before ordering.

How Long It Lasts#

A silicon carbide igniter commonly lasts eight to ten years, and the coils often longer. Thermal cycling wears the igniter, and any physical contact cracks it, so careful handling and a clean, unblocked vent that keeps burner temperatures normal both extend the whole heat system's life.

The Sensor Between Igniter and Flame#

The igniter does not open the gas valve on its own — a sensor stands between them. On many Maytag gas dryers a radiant flame sensor watches the igniter and only lets the coils energize once it detects the igniter has reached full glow temperature. If that sensor fails open, the igniter may glow indefinitely without the coils ever opening, mimicking a coil fault. So when the igniter glows but no flame follows, test the coils first, but do not overlook the sensor — measure its continuity and replace it if the burner will not advance despite good coils. This three-part handshake between igniter, sensor, and coils is why gas-heat diagnosis rewards patience over guessing.

Gas Safety You Must Follow#

Working on a gas appliance demands respect for the fuel. Always close the gas supply valve before opening the burner assembly, and never rely on the dryer simply being off — physically shut the valve. After reassembly, brush a gas-leak detector solution over every joint you disturbed and watch for bubbles with the gas restored but the dryer not yet running. If you smell gas at any point, stop, ventilate, and call a professional or your gas utility. No repair is worth a gas leak in the laundry room, and a licensed technician is the right choice whenever you are not fully confident around the supply line.
