Dryer drum spins normally but no heat is produced — thermostat has shorted open, cutting power to the heating element or gas burner.
Clothes take multiple cycles to dry because the thermostat is cutting heat prematurely before the rated temperature is reached.
Unit repeatedly stops heating or turns off during a cycle as the high limit thermostat trips due to overheating, often from a clogged exhaust vent.
Excessive heat inside the drum or exterior cabinet because the thermostat fails to open at the correct temperature, allowing uncontrolled heat build-up.
💡 Pro Tip: Diagnosing a Failed High Limit Thermostat
Your part is likely the culprit if you notice any of the following:
⚠️ Dryer runs but produces no heat or insufficient heat
⚠️ Dryer repeatedly shuts off mid-cycle before clothes are dry
⚠️ Drum spins normally but heating element / burner never fires
⚠️ Dryer trips the high limit thermostat repeatedly — often signals a clogged exhaust duct or a faulty cycling thermostat (6931EL3004B) causing excessive back-heat
🛠 Veteran tip: Set your multimeter to continuity/resistance mode and probe both spade terminals at room temperature. A healthy thermostat shows a closed circuit (near 0 Ω). An open circuit confirms failure. Before replacing, always check and clear the exhaust duct — a blocked vent is the #1 root cause of repeated thermostat failures on LG dryers.
