The TCO1 110°F High Limit Control Switch is an essential safety component designed for heating, ventilation, and air conditioning (HVAC) systems. Functioning as a thermal cut-off (TCO), this fan disc switch monitors the internal temperature of your appliance to prevent overheating. When the temperature reaches the 110-degree Fahrenheit threshold, the switch opens the electrical circuit to shut down the heating element or motor, protecting the system from potential heat damage and ensuring safe operation. This reliable replacement part is ideal for maintaining furnaces, air handlers, and heat pump systems that require precise temperature regulation and thermal protection.
