Yesterday afternoon while doing laundry i decided to cut the air on and a few hours later i notice it didn't cool the house as much. So i cut it off and the next day i turned it on again and it started working and so i decided to do more laundry. Then an hour latet i noticed it stopped working again. The fan is working outside.

How come it does that?

I doubt the problems are related and could be a coincidence. In the air handler, there is a small unit about 1.5x1.5x.75 that has about 6 wires attached. I forget the name of it but it controls when the fan comes on, goes off. They go bad at times. It costs about $25 I replaced mine about 2 years ago. When they go bad, the outside compressor fan will continue to operate.

I bought one a year ago my brother put it in. But my air is working now i keep it at 75 if i go below it does stop working. I just also thought the dryer had something to do with it

Was the air conditioner put in by a neighbor, relative, or someone else unprofessional? Could it perhaps have been put on the same circuit with the dryer? Or vice versa? Horrors! Hope not, and I'm not an electrician but hopefully someone who is will chime in.

Dryer and AC can't be running on the same circuit because the breaker would trip from overload.

First thing I'd check is the ground bus in the breaker box. Had a similar problem once.

Because of safety issues, this is one best left to professionals, unless you know wiring, and safe practices, very well. Doing things wrong, especially on high power circuits like these, is both a shock and a fire risk. You also need special tools such as voltmeters, ground checkers, hot lead detectors and such.

Well right now when i woke up i just turned down the air conditioning lower and it's working.

It's just weird. Now during the winter i have no problem with the heat and the dryer going on at the same time.

Thank you for responding

If you have gas, propane or oil heat, then the furnace does not draw much power. It's probably on a 120V circuit, whereas central AC, electric dryers, stoves and ovens are on 240V circuits.

So yes, you have a wiring problem.
