This question was probably already answered but to be honest its too darn hot to sit at the PC and go trough all of answers and find right one so I will be quick.
Basically fan works on AC unit but cold air does not come.
I bought the house few months ago and did not use AC until today @ 95F.
Anyhow I removed panel and try to see if any wires are burned or damaged but nothing and then I heard sound on the plug area its has to do with power coz I see 3 wires black, yellow and light blue connected to the what looks like plug that goes in to main unit that looks like stump ( not sure what its called ) its big black thing in the middle.
Two copper houses are connected to it and this plug with 3 wires.
I let it run and every few minutes this cranking sound comes from this 'plug area" as if air unit is trying to kick in but it wont.
Any idea would be helpful or do I need professional for this job.
