The drum spins and the cycle runs, but clothes come out cold and damp — or drying takes two or three cycles.
The #1 cause on LG dryers. It's a one-time safety device — once it blows from overheating (usually a clogged vent), it must be replaced. We replace it and fix the airflow problem that caused it.
Electric models: the heating coil burns out with age. Gas models: the igniter, flame sensor, or gas valve coils fail. All are same-visit repairs for us — we stock these parts.
If the temperature sensor misreads, the control board cuts the heat. Often shows up together with a d80/d90/d95 airflow code.
Not the dryer itself — the duct to the outside. Restricted airflow makes LG dryers overheat, blow thermal fuses, and take forever to dry. We test airflow on every dryer call.
Rare but possible: the relay that powers the heater sticks open. We diagnose it with a meter, not by guessing parts.
| Code | Meaning |
|---|---|
d80 / d90 / d95 | Vent duct 80–95% blocked — clean the duct line |
nP | No power on one 240V leg (electric models) |
tE1 / tE2 | Thermistor (temperature sensor) fault |
If the breaker, settings, and lint filter check out, the fix almost always needs parts and a meter — thermal fuse, element, igniter, or sensor. Our technicians carry the common LG dryer parts on the van, so most no-heat calls are fixed in one visit.
The most common causes are a blown thermal fuse, a failed heating element (or igniter on gas models), or a tripped 240V breaker leg on electric models. A clogged vent is usually the root cause behind the fuse blowing.
No — LG thermal fuses are one-time safety devices and can't be reset. Once blown, the fuse must be replaced, and the airflow problem that caused it should be fixed at the same visit.
Most no-heat repairs (thermal fuse, heating element, igniter) are mid-range repairs — far less than a new dryer. We give you the exact quote after diagnosis, and the diagnostic fee is waived with the repair.
