The Control TCO1 Limit 135DEGF is a critical safety component designed for HVAC and heating systems. This high-limit control switch, also known as a fan disc or thermal cut-off (TCO), is engineered to monitor equipment temperatures and prevent overheating. When the internal temperature reaches the fixed setpoint of 135 degrees Fahrenheit, the switch automatically interrupts the electrical circuit, protecting the appliance from damage and ensuring safe operation. This reliable replacement part is essential for maintaining furnace safety, air handler performance, and overall climate control system longevity. It is a vital component for technicians and homeowners looking to restore the thermal protection features of their heating and cooling units.
