Any A/C techs in the OT?

Check and see if the water pan is full of water. There's a safety switch that prevents the outside unit from running if it's full.

It's underneath the evaporator coils, usually located in the attic.

Capacitor possibly

Check to see if it's bulging

or it's the drip pan need to learn to read the thread before replying.

Wow, I think this is the first time in the history of the OT that it's actually been the drip pan

I have never seen an AC unit where the drip pan is full and the inside evaporator unit still function.

Me neither but I think OP said it was the issue.

I had typed out a reply about checking the contactor and capacitors.

We need to know if outside unit is making a humming noise.

It'll fill back up quickly if you don't unclog the drains.

You know it's just possible the installer broke theY terminal instead of R so the indoor fan would still run

There's a reason the safe pan is full of water.

Probably the condensate drain line is plugged. You could try blowing it out with compressed air or cleaning it out with Clorox. If you don't it's going to back up in the pan again.

First thing I check every time. It is the reason I purchased a shop vac for Christmas. We hauled like 15 or so mop buckets up and down from the attic right before Christmas.

The only time it hasn't been the drip pan for me, I could just go outside and stick a spatula into the vent and manually get the fan spinning.. this is when the unit was humming and trying to run the fan but not spinning I don't recommend anyone go sticking spatulas into their appliances.
