Can the McDonnell Miller 67W-2 LWCO be serviced?

in THE MAIN WALL
I have a WM SGO-4. The low voltage switch on the McDonnell Miller LWCO is intermittent and powering the water feeder when it doesn't need water. I have connected an ohmmeter to the switch terminals and see that it is closing and opening even though the water level is fine. The high voltage part of the switch is fine.

I can't see any way to open this device to replace the switch. Is this designed to be repaired, or disposed of?

    Thanks. It was defective from a month after installation and I finally decided I should do something about it. The LWCO is OK, though:0)

    Yeah, I know. But I really didn't care. Nor did I want to waste the time of the installer since it wasn't his fault. I just figured I would deal with it one day, eventually.
