Why Is My Dryer Not Heating? Thermal Fuse vs Heating Element
A dryer that runs without heating is the most common dryer call we receive across metro Atlanta. The drum spins, the timer counts down, and 60 minutes later the load is still damp. The frustrating part is the dryer appears to work — except for the one thing it is supposed to do.
The good news: this is almost always a single component failure — specifically the thermal fuse or heating element on electric dryers, or the igniter on gas dryers. This guide walks both, plus the underlying cause that you must fix before the new part will last.
Before swapping parts, rule out a clogged vent — a severely restricted exhaust duct causes the same “takes forever, clothes stay damp” symptom. Atlanta townhomes with 20–30 foot vent runs are especially prone.
A clogged vent is also a fire hazard. Clean it before reconnecting and before swapping any electrical parts — otherwise the new thermal fuse blows again within weeks.
The thermal fuse is a one-time safety device that blows permanently when the dryer overheats — almost always from a clogged vent. Once blown, the dryer runs but produces zero heat. It cannot be reset — it must be replaced.
Key detail: If you replace the fuse without clearing the vent that caused it to blow, the new fuse will blow within 1–3 weeks. We always pair fuse replacement with a vent inspection.
Cost: $15–$30 for the part, 30 minutes of labour. The fuse is bolted to the heating-box exhaust on most electric dryers.
The heating element is a coiled resistance wire wrapped around an insulator at the back of the dryer. After 8–12 years the wire fatigues and breaks at one point. Once broken, no current flows and no heat is produced.
How to tell from a thermal fuse: Pull the heating-element box out of the back of the dryer. If you see a visibly broken or scorched coil, the element is dead. Multimeter check: a healthy element reads 8–30 ohms cold; an open element reads infinite.
Cost: $35–$95 for the part, 30–45 minutes of labour. Same-visit repair is normal — we carry the most-common elements on the truck.
Gas dryers do not have a heating element. They use a small ceramic igniter that glows orange to ignite the gas at the burner. The igniter cracks after 6–10 years — the most common gas-dryer no-heat failure.
Quick test: Pull the lower front access panel and watch for the orange glow during a cycle start. No glow = cracked igniter. The igniter glows but no flame = gas valve coils (next section).
If the igniter glows but the gas does not ignite, one of two solenoid coils on the gas valve has failed. The igniter cycles on and off without lighting the gas, so the cycle still has no heat.
Coil replacement is a tech-only repair — gas line work is involved. Coils run $30–$60 for the pair plus labour. We always replace both coils together as one age-matched set.
If neither the heating element, fuse, igniter, nor gas valve is the cause, the next tests are:
A dryer with a chronically clogged vent or a hot-running heating element is a fire risk — the National Fire Protection Association tracks roughly 2,900 dryer fires per year in the US. Atlanta’s long townhome vent runs put us at a higher rate than the national average.
If you smell scorched lint, see scorch marks at the lint trap, or hear the dryer struggling unusually hard, stop using it and book service. We cover the warning signs in detail in our dryer fire safety guide.
