Source1 2435596000 Heater Limit Switch Thermostat L150-40F

Product Description

The SOURCE1 2435596000 is a heater limit switch and thermostat designed to protect heating equipment from overheating damage. This component monitors internal temperatures and cuts power to the blower when the system reaches unsafe heat levels. By interrupting operation before temperatures climb too high, the limit switch shields the heat exchanger, motor, and other internal parts from thermal stress. Once the unit cools to a safe level, normal operation can resume. This makes the limit switch a critical safety device in any forced-air heating system.

HVAC technicians rely on limit switches like this one during service calls involving furnaces and air handlers that short-cycle, overheat, or fail to circulate air properly. A faulty limit switch is a common cause of heating system shutdowns, and replacing it with a direct OEM equivalent like the SOURCE1 2435596000 ensures the system operates within its original design parameters. This unit carries a temperature rating of L150-40F, meaning it opens at 150 degrees Fahrenheit and has a differential of 40 degrees Fahrenheit. That thermal response window is matched to the specific equipment it is designed to serve.

This thermostat and limit switch is a genuine OEM replacement part, engineered for straightforward integration with compatible York and York-branded equipment. The consistent fit eliminates guesswork during installation and reduces callback risk. At 4.6 inches long, 3.7 inches wide, and 2.3 inches tall, it is a compact component with a lightweight profile of 0.025 pounds. Trade professionals stocking replacement heating controls will find this part useful for maintaining service inventory for York systems.
