I have a central a/c that's not coming on,contactor energize on a call for a/c,but nothing outside,not getting 240v to unit? Just a guess bad breaker or no..
Are you getting power to the unit?
Did you check the fuses in the disconnect outside by the unit?
Are you getting control power to the contactor/relay?
did you toggle the breaker off/on?
You may have to remove the breaker panel box cover and see if your getting power off the lugs to the breaker itself.
this is the starting point of the circuit to the A/C unit outside.
with the breaker on and no power from the lugs, then you would have identified a bad breaker.
