Source1 2535363000 Temperature Switch 300F Open Manual Reset

Product Description

The SOURCE1 2535363000 is a manual reset temperature switch designed for use in residential and commercial HVAC systems. It monitors system temperatures and opens the circuit when the temperature reaches 300 degrees Fahrenheit, signaling the heating or cooling system to shut down or take protective action. Once tripped, this switch requires a manual reset before the system can resume normal operation. That manual reset feature is intentional and important. It prevents a system from automatically restarting after a high-temperature fault, which could indicate an unsafe or unresolved condition. An HVAC technician must inspect the equipment, identify the root cause, and manually reset the switch before operation continues. This design adds a layer of protection for both the equipment and the occupants. Temperature switches like the 2535363000 are critical safety components in furnaces, air handlers, heat pumps, and other climate control equipment. They serve as a last line of defense against overheating, which can cause heat exchanger damage, compressor failure, or fire risk. The SOURCE1 2535363000 is a genuine OEM replacement part, ensuring reliable fit and performance in compatible York and Source1 equipment including units such as the 1LD0442, 1LD0407, and 2EE04706324 among others. Using an OEM-grade part maintains the integrity of the safety system and supports proper equipment certification. At just under 1 inch in all major dimensions, this compact switch installs easily in tight equipment spaces. HVAC technicians, service contractors, and maintenance professionals rely on this type of temperature switch for routine safety component replacements during preventive maintenance or emergency service calls.
