- 【Overheat Protection Safety Switch】A HVAC limit switch is a safety device used to shut down equipment. It prevents temperature or pressure from exceeding the switch's rated value. Once the furnace temperature exceeds a preset safety threshold (250°F), the switch automatically interrupts the heating circuit. Once the temperature naturally decreases, the switch automatically resets, allowing the system to resume normal operation.
- 【Easy installation】First, turn off the power to the furnace to prevent electrical hazards. Next, remove the old limit switch from its mounting location and note the wiring configuration. Connect the new L250-40 furnace high limit switch using the same wiring setup and secure it in place. Restore power and test to confirm it activates correctly at high temperature.
- 【After-Sales】We are committed to excellent quality and the best service. If you are not completely satisfied with the purchased goods, please contact us in time, we will give a satisfactory solution.
