Dryer not heating in Calgary? A dryer that tumbles but stays cold forces you to run multiple cycles, costs a fortune in electricity or gas, and can't be solved by just waiting it out. This guide covers every cause — for both electric and gas dryers — so you know exactly what you're dealing with. To book a repair, book online or email calgary@appliancerepairneary.com.
Calgary homeowners face a particularly relevant dryer issue: the city's long winters (5–6 months of active heating season) mean dryers run heavily for extended periods, accelerating lint buildup in vents and wear on heating components. Understanding the relationship between vent blockages and component failures is key to preventing repeat repairs.
1. Blown Thermal Fuse — The Most Common Cause
The thermal fuse is a one-time safety device on every dryer. When the dryer overheats — almost always because the exhaust vent is partially or fully blocked — the thermal fuse blows to prevent a fire. Once blown, the dryer tumbles normally but produces absolutely no heat.
Critical Calgary Warning: Replacing the thermal fuse without cleaning the vent duct is a mistake. The new fuse will blow again within weeks — and in the worst case, the overheating cycle can cause a dryer fire. Always clean your vent when replacing a thermal fuse. Calgary Fire Services records dozens of dryer vent fires annually — this is a real risk, not just a theoretical one.
Thermal fuse replacement cost in Calgary: $80–$130 including parts and labour. The fuse itself costs $8–$25 depending on the brand. If you choose to replace it yourself, first test the vent duct by disconnecting it from the back of the dryer — run the dryer briefly and feel for strong airflow from the disconnected duct. Weak flow means the vent needs cleaning first.
2. Clogged Dryer Vent Duct
Calgary's two-storey infill homes in communities like Altadore, Marda Loop, and South Calgary often have long, multi-bend vent ducts that run up through interior walls to exit at the roof or through the garage. These longer duct runs accumulate lint much faster than the 4-foot exterior wall vents in bungalows.
Signs Your Dryer Vent Is Blocked
- Clothes take 2 full cycles to dry (or don't dry at all)
- The dryer cabinet is very hot to the touch during a cycle
- You can smell a musty or burning lint odour during operation
- The moisture sensor flap on the exterior vent doesn't move freely
- The laundry room feels humid during the dry cycle
Professional vent cleaning in Calgary costs $80–$150 and should be done annually for most households, every 6 months if you have a long duct run or do 8+ loads per week. Our technicians clean the duct as part of dryer repair visits whenever a thermal fuse is involved.
3. Failed Heating Element (Electric Dryers)
Electric dryers use a coiled resistance wire to generate heat. Over time — typically after 8–12 years of use — this element develops a break in the coil, stopping heat production entirely. Unlike a thermal fuse, a failed heating element is usually a gradual failure: the dryer may heat less and less efficiently before stopping altogether.
You can visually inspect the heating element in most electric dryers by removing the back panel — a broken coil will have a visible gap. Replacement cost in Calgary: $120–$220 including parts and labour. We stock elements for Whirlpool, Maytag, LG, Samsung, and GE dryers on our service vehicles.
4. Gas Igniter Failure (Gas Dryers)
Calgary has a high proportion of gas dryers compared to other Canadian cities — natural gas is the dominant heating and appliance fuel in Alberta. Gas dryers use a glow-bar igniter to light the gas burner. When the igniter fails (it glows orange but doesn't get hot enough to ignite gas), you'll see the burner attempt to light, fail, and then the dryer will run cold.
Gas igniter replacement: $130–$200 including labour. Always use a licensed gas technician for any repair involving the gas valve or gas line connections — this is a legal requirement in Alberta.
5. Gas Valve Solenoid Failure
The gas valve has two or three solenoid coils that open the valve to allow gas flow when the igniter is hot. If one or more solenoids fail, the burner may light briefly then go out — the dryer heats for 60–90 seconds then runs cold for the rest of the cycle. This is a classic gas valve solenoid failure signature.
Gas valve solenoid replacement: $150–$250 including parts and labour in Calgary.
6. Faulty High-Limit Thermostat or Cycling Thermostat
Dryers have two thermostats: a cycling thermostat that regulates temperature during normal operation, and a high-limit thermostat that cuts power if temperature exceeds a safe threshold. If either fails in the open position, the dryer produces no heat. These are typically $40–$60 parts with $80–$100 in labour.
7. Control Board Failure
On modern electronic dryers (Samsung, LG, Bosch), the main control board manages all heating functions. A failed board can cause no heat, intermittent heat, or incorrect temperature. Boards are more expensive ($150–$350 parts) and require correct diagnosis before replacement — a good technician will rule out cheaper causes first.
