Dryer runs and tumbles but produces no heat. The blown high-limit thermostat has cut off power to the heating element or gas burner circuit permanently.
Clothes take twice as long to dry as normal. The thermostat is tripping prematurely due to calibration drift or marginal airflow restriction.
On gas dryers, the burner ignites for a few seconds then extinguishes. The high-limit thermostat is cutting out at too low a temperature.
The dryer cabinet or exhaust vent becomes excessively hot. A failed thermostat may no longer regulate the upper temperature limit properly.
💡 Pro Tip: Is Your High Limit Thermostat the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Dryer runs but produces no heat at all
⚠️ Clothes take much longer than normal to dry — 2× the usual cycle time
⚠️ Dryer exterior becomes excessively hot to the touch
⚠️ Gas burner ignites briefly then shuts off after only a few seconds
🔍 Before replacing, use a multimeter to test the thermostat for continuity. A failed high-limit thermostat will show no continuity at room temperature. Also check for lint blockage in the exhaust duct — a clogged vent is the #1 cause of high-limit thermostat failure and will cause the new part to fail again if not cleared first.
