Ensure the safety and efficiency of your heating system with this premium 7-inch high limit switch. Designed as a critical safety mechanism for forced-air furnaces and air handlers, this temperature control switch monitors the heat exchanger to prevent dangerous overheating conditions. If internal temperatures reach the pre-set safety threshold, the switch automatically interrupts power to the heating element or gas valve, protecting your equipment from thermal damage and ensuring the safety of your home. Featuring an L180-30F thermal rating, this switch is engineered to trip at 180 degrees Fahrenheit and reset once the temperature drops by 30 degrees. This reliable replacement part is essential for maintaining proper HVAC airflow safety and meeting standard heat regulation requirements in residential and commercial heating units.
