What to do if the pump will not start or stop on a Magnetrol 3 Series Switch?
If the pump associated with your Magnetrol Switch isn't starting or stopping, examine these external factors: ensure that fuses are intact, reset any tripped reset buttons, verify the power switch is on, check for any issues with the controlled equipment, and inspect the wiring leading to the control for defects.
What to do if float isn't buoyant in liquid in Magnetrol 3 Series?
If the float in your Magnetrol Switch isn't buoyant in the liquid, verify that the float is indeed buoyant. If the float is filled with liquid or has collapsed, replace it immediately.
