Description
The York S1-7660-3591 A/R Lower Limit Switch is a temperature-sensitive safety control used in furnaces and other systems to monitor operating temperatures within the heating section. Designed to open at 150F and automatically close at 130F, it assists in protecting equipment from excessive heat conditions by interrupting the control circuit when temperatures exceed the specified limit in HVAC systems. Commonly installed in compatible heating units, this component works with the furnace control system to maintain proper operating conditions. Its role is to support better operation, protect internal components, and assist with proper heating performance during routine system use.
