Dryer Not Heating: Complete Troubleshooting Guide Toronto

A dryer that tumbles but doesn't heat is one of the most common appliance problems we see. The good news: it's usually caused by a handful of issues, many of which have affordable fixes. This guide walks through systematic diagnosis to find why your dryer won't heat.

Nika Appliance Repair has fixed over 3,400 no-heat dryer problems across Toronto since 2017. Whether you have gas or electric, front-load or top-load, we diagnose and repair same-day in most cases. Let's figure out what's wrong with yours.

Why Dryers Stop Heating

Electric Dryer Heat Problems

• Heating element burnout: Element coil breaks, no heat is produced
• Thermal fuse blown: Safety device triggered by overheating, kills power to heater
• High-limit thermostat: Temperature sensor fails, prevents heating
• Cycling thermostat: Controls heat cycling, failure causes no heat or overheating
• Partial power loss: Electric dryers need both 120V legs - losing one means tumble but no heat

Gas Dryer Heat Problems

• Igniter failure: Glow bar doesn't get hot enough to open gas valve
• Gas valve solenoids: Electromagnetic coils wear out, valve won't open
• Flame sensor: Detects if flame ignites, failure shuts off gas
• Thermal fuse: Same as electric - safety cutoff from overheating
• Gas supply issue: Valve closed, line problem, or gas service interruption

Common to Both Types

• Clogged exhaust vent: Restricted airflow causes overheating and safety shutoffs
• Control board failure: Electronic control can't send heat signal
• Timer malfunction: Mechanical timer doesn't advance to heat cycle
• Moisture sensor issues: Sensor-dry shuts off early, clothes seem wet

Diagnose Your No-Heat Dryer

Step 1: Verify Power (Electric Dryers)

• Check both circuit breakers - electric dryers use two 30-amp breakers
• One tripped breaker means motor runs but no heat
• Reset both breakers - turn off, wait 30 seconds, turn back on
• If breaker keeps tripping, don't force it - call for service

Step 2: Verify Gas Supply (Gas Dryers)

• Check gas shutoff valve behind dryer - handle parallel to pipe is OPEN
• Verify other gas appliances work (stove, furnace)
• If no gas appliances work, contact gas utility

Step 3: Check Exhaust Airflow

1. Go outside and locate dryer vent exhaust hood
2. Start dryer on air-only cycle (no heat)
3. Feel for strong airflow at exhaust hood
4. Weak or no airflow = vent blockage
5. Disconnect vent hose from back of dryer, run dryer - if airflow is strong, duct is clogged

Step 4: Clean the Lint Path

1. Remove and clean lint screen (every load!)
2. Vacuum lint screen housing with crevice tool
3. Disconnect dryer from vent duct
4. Use dryer vent brush to clean duct run
5. Verify no crushing or kinking of flexible duct

Step 5: Test for Heat

• Select timed dry (not sensor) on high heat
• Open door after 5 minutes and feel for warmth
• If drum is warm but clothes don't dry, airflow issue remains
• If drum is cold, heating system needs repair

We always check and clean the exhaust path during no-heat repairs since restricted venting is the leading cause of heating component failure.

When to Call a Professional

While some dryer issues can be resolved with DIY troubleshooting, certain situations require professional expertise:

• Electrical problems: Any repair involving wiring, control boards, or high-voltage components
• Gas appliance issues: All repairs on gas appliances should be done by licensed technicians
• Refrigerant systems: Sealed system repairs require EPA certification
• Persistent problems: Issues that return after DIY attempts indicate deeper problems
• Under warranty: DIY repairs can void manufacturer coverage
