What wrong with my central AC unit ?


It's the solenoid

Yep, just had mine replaced, only cost about 200, and that was with the after hours call out.

Could be the capacitor needs replacing. Easy to tell. Turn power off to the unit. Take the shroud off the back of the unit and inspect the condenser. If it is swollen or seems distorted, that could be the culprit. Before you remove it, discharge it by holding a rubber handled screwdriver across the two leads. They hold power so can arc through you. Once discharged, remove and replace.

Does the outside unit cut on at all? Compressor or fan?

If your compressor is cutting on and off that fast you may have a low pressure switch. See if you can look through the top of the outside unit. Look for wires going to a copper line. If you see some going going to a small switch on the copper lines, you're probably low on freon.

you should have the fan running outside also. If it's not running, put a stick in the guard and spin the blades. If they start spinning, it's a capacitor.

You're just making things up now aren't you.

That's called a flame rollout switch. It prevents heating operation. If his compressor is short cycling (on 5 seconds off 30 or so) 90% chance it's freon levels.

ETA: if your compressor is short cycling, cut that sucker OFF.

I also checked the little pop up electronic kill switch that sits in the T of the primary drain pipe connected to main house drains...it was not backed up with water... ?

Burn your house down and collect the insurance money. It's the only logical thing to do.
