The Short Answer
Every dryer fault lives in one of three systems: heat (fuse, element, igniter), airflow (lint in the vent), or drive (belt, rollers, pulley, switches). Cold air with a running drum is heat; warm air with damp results is airflow; noise or a dead start is drive. Find your lane in the router below and follow it to the dedicated fix.
Three Systems, Three Tells
Strip away the electronics and a clothes dryer is a heater, a fan, and a rotating drum — which is excellent news for diagnosis, because each system fails with its own signature. The heater fails silently: everything sounds normal but the exhaust blows cold. The airflow path fails gradually: each month the loads come out a little damper. The drive fails loudly: squeals, thumps, scraping, or a drum that will not budge. Thirty seconds of observation usually names the guilty system before a single panel comes off.
The Symptom Router
| What the Dryer Does | Prime Suspect | Go Deeper |
|---|---|---|
| Tumbles fine, air stays cold | Thermal fuse, heating element, or gas igniter | No-heat guide → |
| Warm air, clothes still damp | Restricted vent or exhaust duct | Damp-clothes guide → |
| Squealing or thumping while turning | Rollers, belt, or idler pulley wearing out | Noise & belt guide → |
| Press start, nothing happens | Door switch, thermal fuse, or start switch | No-heat guide → |
| Two cycles per load, hot cabinet | Airflow choking inside the duct run | Vent cleaning guide → |
Checks That Cost Nothing
Empty the lint screen and look at it — a torn screen lets lint straight into the duct. Confirm the cycle selected actually heats; air-fluff and eco settings dry slowly by design and get blamed constantly. Open the door and press the switch by hand: no light, no click can mean a failed door switch, which reads exactly like a dead machine. Then step outside during a cycle and feel the exhaust hood — that single test separates airflow trouble from heating trouble better than any other check a homeowner can do.
“The exhaust hood is a lie detector: strong and hot means the dryer is honest, weak and cool means the vent is hiding something.”
Field note — The Technician Team
Gas vs. Electric: What Changes
Electric dryers heat with a resistive element on a 240-volt circuit — and because that circuit uses two breaker legs, losing one produces the classic riddle of a drum that turns while the air stays cold. Gas dryers plug into a standard outlet but burn fuel through an igniter and gas valve; their no-heat pattern is an igniter that glows, clicks, and gives up. Homeowners can reset breakers and clean vents on either type, but the moment fuel lines or 240-volt terminals are involved, the job belongs to our licensed dryer repair technicians — same-day across Sherwood Park, Edmonton, and Strathcona County.
Dryer Questions, Answered
Why does my dryer run but not dry the clothes?
Heat without results means the moisture has nowhere to exit — a lint-restricted vent recirculates humid air through the load. Heat that never arrives at all is a component failure: thermal fuse or element on electric models, igniter or gas valve coil on gas. The two problems feel identical from the outside, which is why the first diagnostic step is always a hand at the exhaust hood.
What usually breaks first on a clothes dryer?
The wear items that move or protect: drum rollers and the belt from mileage, and the thermal fuse from overheating — which is itself usually caused by a clogged vent. That chain is why our technicians treat a blown fuse as evidence and inspect the airflow path before fitting the replacement.
Should I repair my dryer or buy a new one?
Dryers argue for repair more strongly than almost any appliance — they are mechanically simple, and the common failures (fuses, belts, rollers, elements) are modest parts. A machine under 12 years old with one of those faults is nearly always worth fixing; our repair-or-replace bulletin runs the full arithmetic.
