Product Details

Description

The 3-inch Camstat Fan Control is a high-performance thermostatic switch designed for HVAC systems, including residential furnaces and air handlers. This fan disc limit control plays a critical role in system safety and efficiency by automatically regulating the blower fan's operation based on internal air temperatures. With a calibrated range of 90 to 120 degrees, it ensures the fan activates and deactivates at the ideal setpoints to maximize airflow while preventing the heat exchanger from overheating. This replacement part is ideal for repairing heating systems where the fan stays on too long or fails to trigger, providing reliable climate control and protecting your appliance from thermal damage.
