Dryer Not Heating? Here's What to Do

What You’re Experiencing

Your dryer tumbles normally but your clothes come out damp or cold. The drum spins, the timer advances, but there is no heat or barely any. This is the single most common dryer complaint in Atlanta, and in most cases it is a straightforward fix. During the humid months from May through September, Atlanta homeowners notice this problem more acutely because clothes already carry extra moisture from the air.

Common Causes

1. Blown Thermal Fuse

The thermal fuse is a safety device that cuts power to the heating element if the dryer overheats. Once it blows, it does not reset — it must be replaced. This is the number one cause of a dryer not heating and accounts for roughly 40 percent of all no-heat service calls. Typical repair cost: 0–50.

2. Faulty Heating Element

Electric dryers use a coiled heating element that can break or burn out over time. If you see a visible break in the coil, it needs replacement. Typical repair cost: 50–00.

3. Defective Gas Igniter (Gas Dryers)

Gas dryers use an igniter to light the gas valve. If it glows but does not ignite the gas, the igniter is weak and needs replacing. Typical repair cost: 00–50.

4. Clogged Dryer Vent

A clogged exhaust vent restricts airflow, causing the dryer to overheat and the thermal fuse to blow. Atlanta’s humidity accelerates lint buildup in vents, and homes in neighborhoods like Brookhaven, Dunwoody, and Roswell with longer vent runs are especially susceptible. This is the most preventable cause and the most dangerous due to fire risk. Vent cleaning cost: 5–50.

5. Broken Thermostat or Cycling Switch

Thermostats regulate dryer temperature. When they fail, the dryer may not heat at all or may overheat. Typical repair cost: 00–00.

6. Electrical Issues

A dryer requires a 240-volt connection (electric) or both gas and 120-volt power. If one leg of the 240-volt circuit is tripped, the drum will spin but the element will not heat. Check your breaker panel.

Brand-Specific Issues

Samsung Dryers

Samsung dryers frequently blow thermal fuses due to a known issue with lint accumulation around the heating element housing. Samsung models with the Sensor Dry feature may also show a tE or HE error code when heating fails. Check for lint buildup inside the dryer cabinet, not just the lint trap. Samsung recommends professional vent cleaning annually, which is especially important in humid climates like Atlanta.

LG Dryers

LG dryers with the Flow Sense indicator provide early warning when airflow is restricted. If the Flow Sense light illuminates, address the vent blockage before the thermal fuse blows. LG heating elements are generally durable, but the thermistors (temperature sensors) can drift out of calibration over time, causing the dryer to underperform without triggering an error code.

Whirlpool Dryers

Whirlpool electric dryers commonly fail at the heating element, which is housed in a metal can at the rear of the dryer. The element tends to sag and contact the housing, causing a short. Whirlpool gas dryers have a known issue with the gas valve coils weakening over time — the dryer heats initially but stops heating mid-cycle as the coils fail when hot. Replacing both coils during the same visit is the standard fix.

DIY Checks Before Calling a Pro

Check 1: Inspect the Circuit Breaker

A dryer uses a double-pole breaker. It is possible for one half to trip while the other stays on — the drum spins but the heating element gets no power. Flip the breaker fully off, then back on.

Check 2: Clean the Lint Trap and Exhaust Vent

Remove the lint screen and clear any buildup. Then disconnect the exhaust hose from the back of the dryer and check for blockages. A clogged vent is the most common preventable cause of no-heat issues.

Check 3: Test With a Small Load

Overloading restricts airflow inside the drum. Run a small test load on high heat for 10 minutes. If it heats, the issue is airflow, not the heating system.

Check 4: Listen for the Gas Igniter (Gas Dryers)

Start the dryer and listen near the bottom front. You should hear a click and a whoosh as the gas ignites. If you hear clicking but no ignition, the igniter or gas valve is likely failing.

Safety Precautions

Dryer heating problems can involve high voltage electricity and natural gas. Take these warnings seriously:

• Never bypass the thermal fuse. Some online guides suggest jumping the fuse to test the dryer. This removes a critical safety device and creates a fire hazard. Replace the fuse properly.
• If you smell gas, stop immediately. Turn off the gas valve behind the dryer, open windows, leave the house, and call Atlanta Gas Light or 911. Do not flip light switches or use your phone inside the home.
• Electric dryers use 240 volts. This is double the voltage of a standard outlet and can be lethal. Always unplug the dryer before accessing any internal components.
• Clean your vent annually to prevent fires. The Atlanta Fire Department responds to dryer fires regularly. Lint buildup combined with heat is the leading cause. Schedule professional vent cleaning at least once a year.

When to Call a Professional

Call a certified appliance repair technician if:

• The breaker is fine but there is still no heat
• You smell gas near a gas dryer (turn it off immediately and ventilate the area)
• The thermal fuse has blown more than once (indicates a deeper vent or thermostat issue)
• The heating element is visibly damaged
• Your dryer is under warranty and you need authorized service

Questions to Ask Your Technician

• Why did the thermal fuse blow? Simply replacing the fuse without addressing the root cause means it will blow again. A good technician checks the vent, thermostat, and element.
• Should I have my dryer vent cleaned at the same time? Many Atlanta technicians offer vent cleaning as an add-on service during a heating repair. This is the best time to do it since they are already behind the dryer.
• Is my dryer vent too long for code? Atlanta building codes specify maximum vent lengths based on the number of turns. If your vent exceeds the limit, restricted airflow will cause repeated thermal fuse failures.
• For gas dryers, should both valve coils be replaced? If one coil has failed, the other is typically close behind. Replacing both saves a future service call.
• What is the warranty on the repair? Reputable Atlanta technicians typically guarantee parts and labor for 90 days to one year.

Estimated Repair Cost in Atlanta

Most Atlanta technicians offer free estimates and waive the diagnostic fee if you proceed with the repair.

Typical Repair Timeline

Dryer heating repairs are among the fastest appliance fixes:

• Scheduling: Same-day service is often available across metro Atlanta, especially for this common repair.
• Diagnosis: 10–20 minutes to test the thermal fuse, heating element, and thermostat with a multimeter.
• Thermal fuse or thermostat: 20–40 minutes. These are quick-access parts on most models.
• Heating element replacement: 45 minutes to 1.5 hours depending on the dryer model.
• Gas valve coils or igniter: 30–60 minutes for experienced technicians.
