functioning as a normally closed SPST circuit that opens on temperature rise to prevent equipment damage during restricted airflow or over-firing conditions

Maintaining a calibrated thermistor resistance is vital for the defrost logic and refrigerant flow regulation

this limit stop assembly is compatible with both automatic and manual reset series

The 1980-024 provides an open-circuit output of approximately 30 millivolts

Nordyne 626352R Rollout Switch functioning as a normally closedThe Nordyne 626352R is a critical safety component designed for high limit thermal protection in gas fired furnaces. This 250F M R safety rollout switch acts as a primary line of defense, monitoring the burner vestibule for flame rollout or excessive heat buildup. Engineered with a manual reset feature, the 626352R rollout switch ensures that the system remains locked out following a trip, requiring a technician to diagnose the underlying causesuch as
