Product Details

Description

Ensure the safety and efficiency of your heating system with this premium 5-inch high limit control switch. Designed as a critical safety mechanism for HVAC units and furnaces, this thermal limit switch monitors the internal temperature of your appliance to prevent overheating and potential damage to the heat exchanger. It features a fixed temperature setting that automatically interrupts the electrical circuit if the unit exceeds safe operating levels. This specific L175-30F model is engineered to open at 175 degrees Fahrenheit and reset once the temperature drops by 30 degrees, providing reliable protection and peace of mind. Ideal for professional HVAC repairs and routine maintenance, this durable switch is a standard replacement part for residential and commercial forced-air heating systems.
