Source1 2535361000 Limit Switch 165/135 Auto Reset

Product Description

The Source1 2535361000 is a limit switch designed for use in forced-air heating systems, furnaces, and air handlers. Limit switches are critical safety components found in HVAC equipment. They monitor temperature inside the heat exchanger or plenum and shut off the burner or heating element when temperatures rise beyond a safe threshold. This prevents overheating, heat exchanger damage, and potential fire hazards. Without a functioning limit switch, a furnace can overheat and fail prematurely or create unsafe conditions for building occupants. The Source1 2535361000 opens the circuit at 165 degrees Fahrenheit and closes it again at 135 degrees Fahrenheit. This open and close differential helps the system cycle properly and prevents rapid, repeated switching that can wear out other components. The auto reset feature means the switch automatically returns to its normal position once temperatures drop back to the safe range. This eliminates the need for a manual reset after every trip, which reduces service calls and keeps systems running with minimal downtime. HVAC technicians rely on auto-reset limit switches for routine furnace maintenance, component replacement, and system troubleshooting. This part is a direct replacement for failed or faulty limit switches in compatible heating equipment. Proper limit switch function is essential for passing safety inspections and ensuring reliable heat delivery during cold-weather operation. Trade professionals working on residential and light commercial furnaces, heat pumps, and air handlers will find this switch a straightforward, reliable replacement part. Always verify compatibility with the specific equipment make and model before installation.
