The Fan Switch F115-30F is a precision-engineered temperature control designed for forced-air furnaces and HVAC systems. This fan disc switch plays a vital role in indoor climate control by automatically regulating the blower motor's operation based on the temperature within the heating unit. When the furnace plenum reaches the 115-degree threshold, the switch closes to activate the fan, ensuring that only warm air is circulated through your home's ductwork. As the system cools, the 30-degree differential allows the switch to open, shutting off the blower to prevent cold drafts and improve energy efficiency. Durable and reliable, this thermal disc switch is an essential replacement part for maintaining consistent airflow and optimizing the performance of residential heating equipment, particularly in mobile home furnaces and compact HVAC units.
