Check the drain line for stopped up drain and tripped float switch. If clogged clean ran. Also feel the motor on top of condenser to see if it is hot. If it is bad capacitor. Check breaker on outside unit to see if tripped. Russ

ook, I am not paying you for this. Seems you didn't even read my post. I said Air handler was running and condenser was not. Nothing to do with the drain.

I read your post. When drain stops up it will shut down outside unit thru float switch to keep unit from flooding. The inside fan will run. You do not have to pay, Just gave you things to check that a service tech would check first. Russ

No, the drain float switch will shut down the air handler, that is where the water is coming from. air handler shuts down the condenser with shut down. Hey, Learning is fun. This is free. It was a burnt wire in the condenser. I got tired of waiting for an answer.
