Wondering if anyone knows if the magnet thermostat is required to be located on top of, or around the sides of, the magnet? The magnet grabs the ball from the left ramp and puts in to the right flipper ramp. The thermostat protrudes out of the magnet and is also not round thus has to be squeezed into the round housing of the metal ramp holder. Anyone locate this thermostat outside of the magnet? Mine keeps failing and has to be replaced.
