I have had the controller repaired, once. I am trying to remember, but pretty sure it was a capacitor. I try not to even let the controller hit the ground at a little bump....she is one of my babies.
And I really agree....water is not the friend of a foot controller.

Neither are overly moist environments. Unless the boards are protective clear coated.

Our LSMG told us the circuit board in our 930 was to control the voltage for the transformer that powers the motor. Apparently it's not a standard 110-120 volt motor. I do not know the details of this or if he is right or not, as I have only seen pics in the shop manuals. But I do know the machine is a mechanical inside the head. No servos or other things but there are sensors for the stitch pattern levers and the needle up/down thing. So there are electronics inside.
