LG makes some of Toronto's most popular dryers — the DLGX gas series and DLE electric series are found in condos, semis, and detached homes across the GTA. When an LG dryer stops heating, the drum continues to tumble but clothes come out damp and cold, no matter how many cycles you run.
This guide covers every cause of an LG dryer not heating, organized by electric vs. gas, with DIY checks, repair costs in Toronto, and LG warranty information.
Step 1: Clean the Dryer Vent (Do This First)
Before diagnosing any component, clean your dryer vent. A blocked vent is the #1 cause of LG thermal fuse failure — the machine overheats, the fuse blows, and heat stops entirely. Replacing the fuse without cleaning the vent will cause it to blow again within days.
Disconnect the dryer, pull it from the wall, disconnect the duct from the wall vent, and check for significant lint buildup. Toronto condos with long duct runs (over 20 feet) or 90-degree bends are especially prone to blockage. Professional vent cleaning: $80–$150 if you prefer not to DIY.
Electric LG Dryer Not Heating
1. Blown Thermal Fuse (Most Common)
LG electric dryers have a thermal fuse on the exhaust duct or heating element housing. When it blows (always from overheating — usually a blocked vent), the element receives no power. The dryer tumbles but produces zero heat. Testing requires a multimeter: a blown fuse shows no continuity. Replacement: $100–$170 including labour. Always clean the vent at the same appointment.
2. Failed Heating Element
LG electric dryers use a coiled nichrome element in a metal housing. After 5–10 years of use, the coil can break. Unlike a blown fuse, element failure is not always caused by venting — elements simply wear out. A broken element is often visible: look for a gap or burn mark in the coil. Heating element replacement: $150–$270 including labour.
3. Cycling Thermostat or High-Limit Thermostat
LG dryers have multiple thermostats that regulate temperature. The cycling thermostat turns the element on and off; the high-limit thermostat is a safety backup. Either can fail open (no heat) or closed (continuous heat, overheating). Thermostat replacement: $130–$210.
Gas LG Dryer Not Heating
1. Weak or Failed Gas Igniter (Most Common)
LG gas dryers use a glow-bar igniter that must reach sufficient current draw to open the gas valve. As igniters age (typically after 5–7 years), they draw less current — they glow faintly or orange rather than bright yellow-white — and can no longer open the valve. The diagnostic: the igniter glows for more than 60 seconds without a flame. Healthy igniters light gas within 30–45 seconds. Igniter replacement: $160–$280.
2. Thermal Fuse (Gas Models Too)
Gas LG dryers also have a thermal fuse — same blockage-related failure as electric models. If your gas dryer runs and tumbles but produces no heat, check the vent before assuming it's the igniter. Thermal fuse + vent clean: $100–$160.
3. Gas Valve Coils
The gas valve on LG dryers has 2–3 solenoid coils that control gas flow. When these fail, the gas valve won't open even when the igniter is hot and glowing properly. You'll see the igniter glow repeatedly but no flame. Gas valve coil replacement: $160–$260.

Why is my LG dryer not heating?
Most commonly: blown thermal fuse (from a blocked vent), failed heating element (electric), or a weak gas igniter (gas). Start by cleaning the dryer vent — this prevents recurrence and is the root cause of most no-heat LG dryer calls.
How much does LG dryer heating repair cost in Toronto?
Thermal fuse $100–$170, heating element $150–$270, gas igniter $160–$280. All N Appliance Repair repairs include 90-day warranty. Call (437) 524-1053 for same-day service.
Does LG cover heating element failure under warranty?
LG's standard warranty is 1 year parts and labour. If your LG dryer is under 1 year old, contact LG Canada at 1-888-542-2623. If out of warranty, N Appliance Repair provides 90-day warranty on all replacement parts and labour.
