No heat from the start
The drum turns and the dryer sounds normal, but the load stays completely cold within the first few minutes.
Start here: Check the gas supply, cycle settings, and whether the burner tries to ignite at all.
Dryer heating problem
Maytag Gas Dryer Not Heating
Direct answer: If your Maytag gas dryer tumbles but does not heat, the most common causes are a restricted vent, no gas supply, or a burner problem such as a failed dryer igniter, gas valve coil set, or dryer thermal cutoff.
Most likely: Start with airflow and burner behavior. A gas dryer that gets too little airflow can overheat the burner area and open a safety cutoff. A dryer that never even tries to light usually points to gas supply or ignition parts.
First separate no-heat from poor-drying. If the drum turns, the timer advances, and clothes stay cold, you are chasing a heat failure. If clothes come out warm but still damp after a full cycle, airflow is the better first suspect. Reality check: on gas dryers, a bad vent causes a lot of fake part diagnoses. Common wrong move: replacing the dryer igniter before checking whether the gas shutoff is actually open or the vent is packed with lint.
Don’t start with: Do not start by ordering a control board or guessing at parts from one cold cycle.

What kind of no-heat problem do you have?
Heats briefly, then stops
You get a little warmth early in the cycle, then the dryer runs cool for the rest of the load.
Start here: Check outside vent airflow first, then suspect overheating and a failed dryer gas valve coil set or dryer thermal cutoff.
Igniter glows but no flame
You can see an orange glow in the burner area, but you never hear the burner catch.
Start here: That usually points to weak dryer gas valve coils or a gas supply issue, not the dryer igniter itself.
Flame lights once, then will not relight
The first burner cycle works, but later in the load there is no more heat.
Start here: This is a classic dryer gas valve coil set pattern, especially if airflow at the outside vent is decent.
Most likely causes
1. Restricted dryer vent or crushed exhaust duct
Poor airflow makes a gas dryer run hot around the burner housing, which can trip safety parts or cause short heat cycles that feel like no heat.
Quick check: Run a short timed cycle with the vent disconnected from the dryer. If heat returns and airflow at the dryer outlet is strong, the vent path is the problem.
2. Gas supply problem
A closed shutoff, recently interrupted gas service, or another gas appliance issue can leave the dryer tumbling with no flame at all.
Quick check: Make sure the dryer gas shutoff is parallel with the pipe and confirm another gas appliance in the home is working normally.
3. Failed dryer gas valve coil set
When the igniter glows but the burner does not light, or the flame works once and quits on later cycles, the coils are a top suspect.
Quick check: Watch for one good ignition early in the cycle followed by repeated no-flame attempts later.
4. Open dryer igniter or dryer thermal cutoff
If there is no glow, no flame, and the gas supply is on, the igniter circuit may be open from a failed igniter or a safety cutoff.
Quick check: After unplugging the dryer, inspect for a visibly broken igniter and test the dryer thermal cutoff and igniter for continuity if you are comfortable doing that.
Step-by-step fix
Step 1: Make sure this is a heat failure, not just a drying-time problem
A gas dryer with poor airflow can feel like no heat even when the burner is working part of the time. You want to separate a cold dryer from a weak-drying dryer before opening anything.
- Set the dryer to a timed dry heat cycle, not air fluff or a no-heat setting.
- Start the dryer with a medium wet load or a couple of damp towels.
- After 2 to 3 minutes, open the door and feel for obvious warmth inside the drum.
- Go outside and check the exhaust hood. You want a strong, steady blast of warm air, not a weak puff.
- If airflow outside is weak, inspect for a crushed flex duct behind the dryer or a lint-packed vent run.
Next move: If the drum is warming and the outside airflow is weak, fix the vent restriction first. The dryer may not need internal parts. If the drum stays cold and the outside vent airflow is normal or there is no heat even with the vent disconnected, move to gas and burner checks.
What to conclude: Strong airflow with no heat points away from a simple vent issue. Weak airflow keeps vent restriction at the top of the list.
Stop if:
- You smell gas at any point.
- The vent duct is damaged, torn, or packed so tightly with lint that it needs full cleaning before more testing.
- The dryer cabinet becomes unusually hot or you see scorching around the exhaust connection.
Step 2: Check the gas supply before chasing burner parts
A gas dryer cannot heat without fuel, and this is an easy miss after moving the dryer or doing other work nearby.
- Pull the dryer out enough to see the gas shutoff valve if it is accessible.
- Confirm the shutoff handle is in the open position, parallel with the gas pipe.
- If your home has another gas appliance, verify it is operating normally.
- Listen when the dryer starts. A normal gas dryer often gives you a short pause before the burner tries to light.
- If the dryer was recently installed or moved, make sure the gas line was actually turned back on after hookup.
Next move: If opening the shutoff restores heat, run the dryer and then keep checking for normal burner cycling and normal vent airflow. If the gas supply appears normal and the dryer still stays cold, the next step is to watch the burner behavior.
What to conclude: No gas supply can mimic several bad-part symptoms. Once gas supply is ruled out, burner behavior becomes much more useful.
Step 3: Watch for glow, flame, and relight behavior
This is the cleanest way to separate the common gas-dryer failures without buying parts blindly.
- Unplug the dryer before removing the small lower access panel if your model has one, then restore power only after the panel is safely off and you are clear of moving parts.
- Start a timed heat cycle and watch the burner area from a safe distance.
- Look for three patterns: no glow at all, glow but no flame, or flame once then no relight later.
- If there is no access panel, listen instead: you may hear the igniter cycle and gas valve click, then either ignition or silence.
- Let the dryer run long enough to see whether it lights only on the first cycle and then quits.
Next move: If you clearly identify the pattern, you can narrow the repair instead of guessing. If you cannot safely observe the burner or the pattern is unclear, stop at basic checks and call for service rather than replacing multiple parts.
Step 4: Check the vent path if the burner lights once or heat fades during the cycle
Gas dryers often lose heat because the burner area gets too hot from poor airflow. That can shorten flame cycles or open a dryer thermal cutoff.
- Unplug the dryer and disconnect the vent from the dryer outlet.
- Clear loose lint from the dryer outlet and the first section of duct by hand or with a vacuum.
- Inspect the flex duct for kinks, crushed spots, or heavy lint buildup.
- Run the dryer briefly with the vent still disconnected and the room well ventilated.
- If heat returns or the burner now relights normally, clean or repair the full vent run before replacing dryer parts.
Next move: If the dryer heats normally with the vent disconnected, the vent system is the main problem. Correct that first and then retest the dryer fully assembled. If the dryer still has no heat or still loses flame with the vent disconnected, the fault is likely inside the dryer.
Step 5: Replace the part that matches the burner pattern, or call for service if the pattern stays muddy
By this point you should have enough evidence to avoid the usual guess-and-buy cycle.
- If the igniter never glows and gas supply is confirmed, test and replace the failed dryer igniter or the open dryer thermal cutoff that feeds the ignition circuit.
- If the igniter glows but there is no flame, or the flame works once and quits later, replace the dryer gas valve coil set.
- After any repair, reconnect the vent, restore power and gas, and run a timed cycle to confirm steady heat and strong outside airflow.
- If the dryer still has no heat after the matched repair, stop before ordering more parts and have the burner circuit professionally diagnosed.
- If you found a blown dryer thermal cutoff, treat vent restriction as part of the repair, not a side note.
A good result: If the burner now lights, cycles normally, and the load dries in a normal time, the repair path was correct.
If not: If the matched part does not fix the problem, the remaining causes may involve wiring, flame sensing, or control issues that are not good guesswork repairs.
What to conclude: A clear burner pattern supports a focused repair. A muddy pattern after the basic checks is where professional testing saves money.

FAQ
Why is my Maytag gas dryer running but not heating?
Most often it is a vent restriction, no gas supply, or a burner problem. On gas dryers, the burner pattern tells the story: no glow points toward an igniter circuit issue, while glow with no flame or one flame then no relight usually points to the dryer gas valve coil set.
Can a clogged vent make a gas dryer seem like it has no heat?
Yes. A restricted vent can make the burner area run too hot, shorten heat cycles, or open a dryer thermal cutoff. The dryer may tumble normally but still leave clothes wet and cool by the end of the load.
If the igniter glows, is the igniter good?
Usually yes. A glowing igniter means that part of the circuit is working. If it glows but the burner does not light, the stronger suspects are the gas supply or the dryer gas valve coil set.
What does it mean if the dryer heats once and then stops heating?
That is a very common dryer gas valve coil set symptom. The coils can work when cold, then fail once they warm up. Check airflow too, because overheating from a bad vent can make the problem show up faster.
Should I replace the dryer thermal cutoff without checking the vent?
No. If the dryer thermal cutoff is open, there is often an airflow reason behind it. Replacing the cutoff without fixing a blocked or crushed vent can lead to the same failure again.
Is this safe to troubleshoot myself?
Basic airflow checks, gas shutoff confirmation, and unplugged continuity testing are reasonable for many homeowners. Stop and call a pro if you smell gas, find burnt wiring, or need live testing to go further.
