Description

This 11-1/2 inch adjustable fan and limit switch is a critical safety and operational component for forced-air heating systems.

It features a vital high-limit safety cut-out that prevents the heating system from overheating, protecting your equipment from potential damage. With its adjustable settings, users can precisely calibrate the fan-on and fan-off temperatures to optimize energy efficiency and indoor comfort. Whether you are repairing a residential furnace or maintaining a commercial HVAC unit, this heavy-duty bimetal probe switch provides reliable, long-lasting performance as a replacement for faulty or worn-out temperature controllers.
