 |  "AC compressor not coming on"
, posted Sat 28 Jun 19:37:  
My home AC system was working fine until the circuit breaker tripped. Now, only the fan comes on in the unit, but the compressor isn't coming on. I can tell because the house isn't being cooled and I don't hear that familiar buzzing sound from the unit. Just warm air is blowing through the vents.
Last summer, I replaced the blower fan and it was working fine until today.
Could it be the regulator?
This unit is original from the 60s. It's Fedders brand. Any help would be appreciated.

I don't want to sound like a partschanger but honestly, I wouldn't waste the money on a service call. Most likely your compressor is stuck. This would be a good opportunity to upgrade.

Thanks for the reply. If the compressor became stuck, would that trip the breaker?

Certainly. Now it's not turning on because the internal overload is open. It may be salvageable but you've gotta "draw the line" at some point soon. At 40 something years old I would say the unit crossed that line 15 years ago!

I understand but I'd rather not spend the money on a new unit. That's why I fixed it myself last summer. How would I be able to salvage this unit? Is the compressor totally shot or is there something that can be done to get it working again?

Do you have a meter? If so then disconnect power to unit and remove the 3 compressor wires from each terminal. Check ohms from each to each for example: R to S, R to C, And S to C.
Is compressor hot to the touch?
While you're at it look at the capacitor if it's swollen or leaking fluid it is bad. There are other ways to test it but start with the ohm readings for now.

What resistance measurement values are expected? Pass vs Fail?

There is in fact power going to the compressor. Looks like it's time for a replacement. Thanks for the help.

Before handling the capacitor I would highly recommend taking a screwdriver and putting it across both legs at the same time to degenerize it.
