imUfer Water Softener Rotor Position Switch 7305150 Compatible WS21X10003

When your water softener experiences error 1 or error 3, and the rotor at the top of the softener keeps rotating, making a loud whining sound, then your position switch should be faulty.
The metal piece sticking out of the switch needs to ride on the cam wheel, so that the switch can turn on and off as the cam wheel turns. This slight move forward, in the unit, causes the metal tab to properly track in the rotating guide.
Easy to install: Plug in connector, just find the product location and easily replace it, very user-friendly for beginners.
