Product Details

Description

Ensure the safety and efficiency of your heating system with this 3-inch high limit switch. Designed as a critical thermal safeguard for forced-air furnaces and HVAC units, this switch monitors internal temperatures to prevent overheating. If the furnace plenum reaches a designated temperature, the switch automatically breaks the electrical circuit, protecting your equipment from heat damage and potential fire hazards. This specific limit control features a 160-degree Fahrenheit opening point and a 30-degree differential for a reliable reset. It is an essential replacement part for restoring proper heating cycles and maintaining consistent climate control in residential or commercial forced-air systems.
