HAVC unit won't come on

This morning I noticed that my main floor wasn't cooling. I checked and found the condensation pump full ( little giant model VCMA-15ULS ). I disconnected the hose from the unit to the pump, drained it, dumped the pump and reconnected it.

The aprilaire 8446 display unit clicks when I turn down the temperature but the hvac unit itself ( model FA4CNF030, doesn't show manufacturer ) never comes on. I've tried turning the circuit on / off at the power panel.

I also tried swapping out pumps with another and disconnecting the switch that is in the pan at the bottom of the unit for condensation flooding. Each time I powered the unit off and even hit reset on the aprilaire control unit at the wall.

What else can I do to try and get this puppy to come alive?
