Gas Dryer Not Heating? 6 Causes and When to Call a Pro

A gas dryer that tumbles but does not heat is usually missing gas flow or ignition, most often because of a failed igniter, a faulty gas valve coil, a tripped thermal fuse, or a clogged vent. Check the vent and the gas supply first, then call a technician for anything involving the burner.
Start with the two quick checks
Before you assume a part has failed, confirm the gas supply valve behind the dryer is open and the dryer is on a working 120-volt outlet, because a gas dryer still needs electricity to run the controls and igniter. Then clean the lint screen and look at the vent hose. A crushed or lint-packed vent traps heat, trips safety devices and makes clothes take two or three cycles to dry.
The six common causes
- Weak or failed igniter. The igniter glows to light the gas. When it weakens, it glows but never opens the gas valve fully, so the burner never lights.
- Gas valve coils. The coils open the valve. A worn coil gives you a click and no flame.
- Blown thermal fuse. This safety fuse trips when the dryer overheats, often from a blocked vent. The dryer then tumbles with no heat.
- Cycling thermostat or high-limit thermostat. A failed thermostat cuts heat early or never allows it.
- Flame sensor or control problems. The sensor tells the control that gas is burning; a failing one shuts the burner down.
- Restricted exhaust vent. The most common root cause, and the one that destroys parts if it is ignored.
Which repairs are safe to attempt
Cleaning the lint screen and vent is safe for any homeowner. Anything that touches the gas line, burner assembly or valve is not a good DIY project: a bad connection can leak gas. If you smell gas at any point, stop, leave the house and call the gas utility from outside.
What the repair usually looks like
A technician confirms the vent flow, tests the thermal fuse and thermostats, then checks igniter amperage and the valve coils. Most gas dryer heat problems are fixed with one part. Nationally, dryer repairs commonly land between about $150 and $500 depending on the part and whether the dryer is gas or electric; our dryer repair cost guide breaks the tiers down.
Repair or replace?
If the dryer is under ten years old and the fix is a single igniter or fuse, repair is almost always the better value. If it is older and needs several parts, see our repair-or-replace guide.
Frequently asked questions
Why does my gas dryer run but stay cold?
The drum motor and the burner are separate systems. The motor can run perfectly while the igniter, gas valve or a safety fuse prevents the flame.
Can a clogged vent really stop the heat?
Yes. A blocked vent causes overheating, which trips the thermal fuse or high-limit thermostat and shuts the burner off.
Is it safe to keep using a dryer that is not heating?
Running it repeatedly with a clogged vent is a fire risk. Fix the airflow first.
How long does a gas dryer repair take?
Most are completed in a single visit when the part is on the truck.
How often should I clean the vent?
At least once a year, or more often with heavy laundry loads.
Understanding Repair Costs in Georgia
Costs depend on the appliance, part, and labor. National price ranges run roughly $50 to $150 for a diagnostic visit, $100 to $300 for dishwashers, $100 to $400 for ovens, $125 to $500 for washers, $150 to $500 for dryers, and $200 to $500 for refrigerators. A flat-rate quote before work keeps you in control, and the diagnostic fee is waived with any repair.
Why Early Repairs Save Money
Small problems grow. A worn belt can damage a drum, a leaking hose can ruin a floor, and a clogged coil can burn out a compressor. Calling at the first sign of trouble usually costs a fraction of waiting for a total failure. With upfront flat-rate pricing and the diagnostic fee waived with any repair, there is little reason to wait.
Parts Availability and OEM Quality
Technicians who stock common OEM parts can often finish a repair in a single visit. Aftermarket parts vary in quality, and some void warranties. Ask whether the part is OEM, and keep the old part for your records. Model and serial numbers on the appliance label let the technician order the exact match.
Preventive Maintenance Calendar
Every few months, take ten minutes to vacuum coils, clean filters and lint traps, inspect hoses and gaskets, and run cleaning cycles. Once a year, schedule a vent cleaning and a visual check of power cords and water lines. Preventive care costs far less than emergency repairs and keeps warranties valid.
Repair or Replace a Dryer
Dryers often run fifteen years or more. A repair costing under half the price of a new unit is typically worth doing, especially for a model with solid construction. Fire safety concerns, damaged drum surfaces, and repeated failures of the same part are reasons to consider replacement.
How a Dryer Heats and Moves Air
A dryer pulls room air across a gas burner or electric heating element, tumbles clothes in the drum, and pushes the moist air out through the vent. Thermal fuses, high-limit thermostats, a cycling thermostat, a moisture sensor, and a belt-driven motor control the process. When a dryer runs but does not dry, the cause is nearly always airflow, heat, or both. Checking airflow first costs nothing and often solves the problem.

Service Lead Heroes technicians cover Jonesboro, Riverdale, Morrow, Forest Park, Lake City, Lovejoy, and nearby cities in Clayton, Henry, and Fayette Counties. Call (470) 847-9076 to schedule, and describe the brand, model, and symptoms so we can arrive prepared with likely parts.
Drum Noise, Belts and Rollers
Thumping, squealing, or scraping sounds typically come from a worn drum belt, glides, rollers, or an idler pulley. A belt that snaps leaves the drum motionless while the motor runs. Replacing the belt, idler, and rollers at the same time often makes sense because they wear together, and the dryer is already opened up.
What Our Diagnostic Visit Includes
Every visit starts with a full inspection, test of the suspect components, and a flat-rate quote before any work begins. The diagnostic fee is waived when you approve the repair, parts and labor are covered by a 90-day warranty, and same-day appointments are available when scheduled. You approve the price first, so there are no surprises.
Power Surges, Storms and Electrical Protection
Georgia thunderstorms and utility switching can send voltage spikes through household wiring. Control boards and sensors are the first parts to suffer. Plug major appliances into properly grounded outlets, consider a whole-home surge protector, and unplug sensitive units during severe lightning. If an appliance dies right after a storm, tell the technician, because it points straight toward the control board.
Thermal Fuse and Thermostat Problems
The thermal fuse is a one-time safety device that blows when the dryer overheats, usually from blocked venting. Replacing the fuse without clearing the restriction only leads to another failure. High-limit and cycling thermostats can also wear out and cause erratic heat. Always address the airflow problem and the failed part together.
Heating Element or Gas Igniter Failures
On an electric dryer, a burned-out heating element or a tripped breaker leaves the drum spinning with no heat. On a gas dryer, a weak igniter or faulty gas valve coil prevents the burner from lighting. A technician can test continuity on each part, which prevents guessing. Replacing a failed element or igniter is among the most routine dryer repairs and usually restores performance in one visit.
Safety Habits Every Household Should Follow
Keep the area around appliances clear of cardboard, cleaning chemicals, and clutter. Never defeat a safety switch, and replace damaged cords immediately. Test smoke and carbon monoxide detectors, especially if you have gas appliances. Teach everyone in the home where the gas shut-off and the electrical panel are located.

Frequently Asked Questions
What should I have ready before the technician arrives?
Locate the model and serial number label, write down any error codes, and note when the problem began. Clear a path to the appliance so the technician can work safely.
Should I repair or replace an older dryer?
As a rule of thumb, if the repair costs less than half of a new unit and the appliance is under about twelve years old, repair is usually the better value. We will tell you honestly if replacement makes more sense.
How much does dryer repair cost in Georgia?
Costs vary by part and labor. The diagnostic visit usually runs $50 to $150 and is waived with any repair. You receive an upfront flat-rate quote before work begins, so you decide with the full price in hand.
Is the repair covered by a warranty?
Every repair includes a 90-day parts and labor warranty. If the same problem returns within that period, we come back and make it right.
