Got home today to find that my ac would not come on. I checked all of the fuses. Checked the thermostat. Realized that my compressor outside is running, but my fan in the attic isn't coming on to pump the cold air in. Can anyone help please?

Start by checking the drip pan in the attic

The first things I would check are the run capacitor connected to the fan motor in the air handler, or the fan motor itself.

Do you have a drip pan under the unit? . Check it to see if it's full of water.

If it ain't that prepare your anus...

Oh and there's some dude called fat ed on here that is in that business.

Make sure your drip pan in the attic is empty.

Normally the float switch cuts the whole system off, though.

Check the capacitor. If it is bulging it is bad and can be easily and cheaply replaced.

isnt the capacitor usually for the outside fan and compressor? first thing you should do is put the fan selector switch in on position instead of auto and see if it comes on. probably a control board or something if it doesnt come on when the switch is in on position.

Systems are different. Look around and see.

On the outside compressor, there are capacitors on some as part of a hard start kit that not all systems need.

But blower motors and fan motors have them too.

I know you said you checked all of the fuses...I would check them all again...there should be a breaker in the breaker box and either a breaker or a fuse at both the inside and the outside units...be sure all of that is in good working order...

Just came home to a hot as hell house.

Thankfully the drip pan was full. Finally got to use my gallo gun

Ac is cooling now, and I didn't break anything trying to get the CO2 cartridge in

pour a little bleach down the drain line to kill the algae that stopped it up...make sure no bleach stays in the drain pan though, or it will rust out...

I can get some tomorrow.

I'm glad I work in apartments and get the maintenance guys to teach me things. Husband is normally useless and is gone right now.

Gonna try to change my tub stems one of these weekends.

Do love the gallo gun, though

Not gonna lie, I breathed a HUGE sigh of relief when I saw all that water because cleaning out the drain line is the extent of my hvac knowledge

that is really about all a normal individual can do except maybe replacing a bad breaker or fuse...everything else requires instrumentation or is pretty dangerous...

Yeah. The fan doesn't turn on when I switch it to on. Is that a tstat or controll panel?
