LG Dryer Not Heating

TL;DR

• An LG dryer that runs but won't heat is usually a failed heating element, a blown thermal fuse, a bad thermistor, or a tripped thermal cutoff, and clogged venting is behind a surprising number of these failures.
• If your electric LG dryer tumbles but stays cold, one of your two home circuit breakers may be tripped. A dryer needs both halves of its 240V circuit; lose one and it runs but won't heat.
• Restricted airflow from a lint-packed vent is the number-one cause of blown thermal fuses. Fixing the fuse without clearing the vent just blows it again.

An LG dryer that spins for an hour and leaves your clothes damp and cold is one of the most common laundry calls we get. The frustrating part is that everything looks like it's working, the drum turns, the light comes on, the cycle counts down, but there's no heat. Here's what's actually going wrong and how to tell a five-minute fix from a real repair.

Why is my LG dryer not heating?

For LG dryers, no-heat problems trace back to a short list of parts. In order of how often we find them:

• Blown thermal fuse. A safety device that permanently cuts heat if the dryer overheats, usually because of restricted airflow. Once it blows, the dryer runs but never warms. It must be replaced, not reset.
• Failed heating element. On electric models, the coil that produces heat burns out over time. No element, no warmth.
• Bad thermistor or thermal cutoff. These regulate and limit temperature. When they fail, the control board may shut heat off entirely.
• Tripped half-circuit (electric models). A 240V dryer uses two 120V legs. If one breaker trips, the motor still runs on the remaining leg but there's no power for heat.
• Gas valve or igniter (gas models). On gas LG dryers, a worn igniter or failed gas valve coil stops the burner from lighting.

What can I check before calling a technician?

• Check both breakers. Go to your panel and fully flip the dryer's double breaker off, then on. A partially tripped 240V breaker is a genuinely common and free fix for electric models.
• Inspect the vent and lint trap. Clean the lint screen, then check the vent hose and exterior vent flap for clogs. Restricted airflow is the root cause behind most blown fuses, so this matters even after the repair.
• Feel the exhaust vent outside while the dryer runs. Little to no airflow means a blockage that needs clearing.
• Confirm it's not a settings issue. Air Dry or Fluff cycles run without heat by design. Make sure you're on a heated cycle.
• Do not bypass a thermal fuse or run the dryer with the back panel off. These are safety components for a reason.

How much does an LG dryer repair cost?

Most LG no-heat repairs fall in the $140 to $450 range:

Problem	Typical repair range	Part involved
Thermal fuse	$140 to $250	Thermal fuse (plus vent cleaning)
Heating element	$200 to $400	Heating element assembly
Thermistor / thermal cutoff	$160 to $320	Thermistor, cutoff switch
Gas valve coils / igniter	$180 to $380	Igniter, gas valve coil

The $80 diagnostic is waived when you approve the repair, and every job carries our 60-day parts and labor warranty. Since a new LG dryer runs $700 to $1,300, a no-heat repair is almost always the far cheaper path.

Why clearing the vent matters as much as the repair

Here's the part cheaper shops skip: a blown thermal fuse is a symptom, not the disease. If the real problem is a lint-clogged vent restricting airflow, replacing the fuse alone means it'll blow again within weeks. A clogged dryer vent is also a genuine fire hazard, which is why we check and clear airflow as part of any no-heat repair, not as an upsell but because doing it right is the whole point.
