36680 Sail Switch:
Sail switch is the first of two safety switches in the forced-hot-air system. It exists to prevent the furnace from even trying to ignite if the blower fan can’t run at the proper speed. This can happen under certain circumstances, including if your RV’s house battery bank is discharged too low to run the fan at full speed.
High Quality Materials:
The shell is made of high-quality plastic, and the sail blades are made of high-quality steel to avoid corrosion and functional degradation of the shell. High-quality tinned copper wires are used inside to improve the durability of the sail switch. This is your best bet.
