Description
The York S1-8866-3281 Auto Limit Switch 95-130F is a temperature-responsive control component that monitors internal heat conditions in furnace and air handling equipment. It operates by automatically changing electrical contact status when temperatures rise to 130F and resetting once conditions decrease to 95F, allowing controlled cycling based on system temperature levels. Within HVAC systems, it supports blower and heating circuit management by reducing excessive heat buildup during operation. Installed near the heat exchanger or airflow section, it connects into the control circuit to regulate component activity according to temperature changes for stable and consistent equipment operation.
