A dryer that runs normally — tumbling clothes, displaying time, cycling the drum — but produces no heat is one of the most common appliance repair calls in Toronto. The laundry pile grows, damp clothes sit in the drum, and the dryer just keeps spinning uselessly. Frustrating, but almost always fixable in one visit.
This guide covers every cause of a dryer not heating, organized by electric vs. gas dryers, with repair costs, DIY assessment, and what to expect from professional repair in Toronto.
Electric Dryer Not Heating — 4 Main Causes
1. Blown Thermal Fuse (Most Common)
The thermal fuse is a one-use safety device that protects the dryer from overheating. When it blows, the dryer loses heat entirely but continues to tumble. A blown thermal fuse almost always means the dryer venting is partially blocked — lint buildup in the vent hose, exterior vent cap, or duct run restricts airflow and causes excessive heat buildup. Replacing the fuse without cleaning the vent will result in another blown fuse within weeks.
Repair cost: Thermal fuse replacement including vent inspection: $100–$170.
2. Failed Heating Element
Electric dryers heat air by passing it over a coiled nichrome heating element in a metal housing. After years of use (or following a power surge), the element coil can break, interrupting the circuit. Unlike a blown thermal fuse, a failed element is not always caused by venting — elements simply wear out. Visible signs include a break in the coil or scorch marks inside the element housing. Heating element replacement: $150–$260 including labour.
3. Cycling Thermostat Failure
The cycling thermostat regulates dryer temperature during operation, turning the heating element on and off to maintain the set temperature. A failed cycling thermostat may leave the element permanently off (no heat) or permanently on (overheating). It is located on the blower housing and is inexpensive but requires disassembly to reach. Cycling thermostat replacement: $130–$200.
4. Tripped Circuit Breaker (Electric Dryers Only)
Electric dryers in Canadian homes draw 240V across two 120V legs. The motor runs on one leg and the heating element on the other. If one leg of the 240V circuit trips, the dryer will run (motor is functional) but not heat (element has no power). Check your electrical panel for a partially tripped breaker. Reset it fully and test. If it trips again, call an electrician — there may be a wiring or breaker fault.
Gas Dryer Not Heating — 3 Main Causes
1. Failed Gas Igniter
Gas dryers use a glow-bar igniter to ignite the gas burner. The igniter heats until it glows orange, triggering the radiant sensor to open the gas valve. Igniters typically last 5–10 years before the glow element burns out. Signs of a failed igniter: the burner does not light on any cycle, you can smell gas very faintly (gas valve opens but flame doesn't ignite), or you hear the gas valve click but no heat follows. Gas igniter replacement: $160–$270.
2. Faulty Gas Valve Coils (Radiant Sensor)
The gas valve has multiple solenoid coils (flame sensor, boost, hold) that open and close to control gas flow. When these coils fail, the gas valve won't open even when the igniter is glowing. Symptoms: igniter glows bright orange repeatedly but burner never lights. The coils are relatively inexpensive but require careful diagnosis to confirm. Gas valve coil replacement: $170–$280.
3. Thermal Fuse (Gas Dryers Too)
Gas dryers also have a thermal fuse — and it blows for the same reason as in electric dryers: blocked venting. If your gas dryer runs but doesn't heat, check the vent before assuming it's the igniter. Thermal fuse on a gas dryer: $100–$160 to replace. Always clean the vent at the same time.
Step 1: Clean the Dryer Vent First
Before calling for service or ordering parts, disconnect the dryer from the wall and pull it forward. Disconnect the flexible duct from the wall vent. Check for:
- Significant lint buildup inside the flexible duct (replace it if heavily clogged — they are inexpensive)
- A crushed or kinked flexible duct (common behind stacked washer/dryer setups in Toronto condos)
- A blocked exterior vent cap (bird nests, debris, or a stuck flap are common)
- A duct run longer than 25 feet (too long for proper airflow — reduce length or upgrade to rigid metal duct)
If the vent was significantly blocked, replace the thermal fuse (the most common part failure from vent blockage) and test. In many cases, this resolves the no-heat issue without further parts.

Call (437) 524-1053 Book OnlineFrequently Asked Questions
Why is my dryer running but not heating?
The most common cause is a blown thermal fuse — a safety device that trips when the dryer overheats (usually from a blocked vent). The dryer continues to run because the motor circuit is separate from the heating circuit. Clean your vent and replace the thermal fuse to restore heat.
How much does dryer heating repair cost in Toronto?
Thermal fuse replacement is $100–$170. Heating element is $150–$260. Gas igniter is $160–$270. All Appliance Repair Near Me repairs include 90-day warranty. Call (437) 524-1053 for a same-day appointment.
Can I fix a dryer not heating myself?
You can clean the dryer vent yourself — this is the most important first step. Replacing a thermal fuse or heating element is possible for DIYers comfortable with appliance disassembly. For gas dryers, call a licensed technician for igniter and valve work to ensure safety.
How long does dryer heating repair take in Toronto?
Most dryer heating repairs take 60–90 minutes and are completed in a single visit. Our technicians carry the most common parts on the van, so there is rarely a wait for parts ordering.
