My problem is that my A/C is basically broken right now. I have an
American Standard Freedom 90 furnace and an Allegiance 13 (I think) AC
unit outside. I turn the A/C on at the thermostat and the condenser kicks
on outside (I can see the fan rotating) but the house does not cool down.
In fact, I end up with a puddle on my basement floor around the furnace
because the coolant lines quickly freeze up and I get massive condensation
built up (and eventually melting ice). I'm guessing the blower is not
running but have no clue how to fix it or what caused it to stop running
in the first place. The light on the front is blinking 6 times which
indicates a "115 VAC reverse polarity or grounding problem" but I don't
think either of those are really the problem unless the gurgling water
problem that I mention below somehow caused a grounding issue.

The A/C was working on Thursday night. Friday when I get home from work
the house was warm. I inspected the condensation line (not sure what it is
really called) and it was frozen. I let everything thaw out but it still
wouldn't work. Today I noticed the hose, which leads on one end to what
looks like fan in a black casing in the upper portion of the furnace unit,
was not connected. I connected it and I also flipped the breaker. Still
have the light flashing 6 times. Setting the thermostat to "fan" doesn't
do anything either.

The furnace and A/C units are only about 15 months old.

You are on the right track. The fan not running will cause the freeze up.
The questions is why is it not running and that is more difficult to
diagnose from here. Things you can check though, are loose wires and,
broken belt if a belt drive Turn the power off. Open the furnace and give
the blower a spin. The blower and motor should spin fairly freely. Look at
any wiring connections and be sure they are tight and connecting. Without
proper equipment, such as a multi-meter, you can't do much more. My guess
is it is more involved, but sometimes simple things like a wire knocked
loose by the service guy can happen.

Could be a bad motor, bad relay, bad ground, bad circuit board, bad
capacitor (if motor is so equipped)
