I have another switch that is above my sink that supplies the 12 volts to the unit. Neither the unit nor the controller for the unit will turn on. I'm assuming the controller won't turn on because the unit obviously isn't drawing any power.

A white neutral wire for an AC circuit is completely different than a black negative wire in a DC circuit. You cannot mix AC and DC wiring!!!!
AC circuits provide alternating current while DC circuits provide direct current and each one has its own separate source for generating power / voltage.
The reason the unit will not power on is that you have the positive (red) wire attached to the + side of 12V power supply but the negative (black) wire is connected to the neutral wire of an AC circuit (that is not ground or the negative side of 12V) so the unit is not connected to the negative post (-) of the 12V power supply (house battery / Converter) so you have no power to the unit.
The attached is right out of the Girard Service Manaul.....
