This premium automatic reset high limit disc switch is a vital safety component for residential heating systems and furnaces. Designed to provide thermal protection, this fan disc switch monitors the internal temperature of your HVAC equipment, automatically opening the circuit if the unit exceeds its safe operating limit of 230 degrees Fahrenheit. Once the system cools down by the designated 20-degree differential, the switch resets itself to restore normal operation. Ideal for furnace repair and routine HVAC maintenance, this reliable limit control prevents overheating and ensures the longevity of your heating system. It is a common replacement part for gas and electric furnaces that require a normally closed thermal disc for blower motor control or high-limit safety sensing.
