I have a rather old central ac unit. It wasn't working at all and it

it trips the breaker. It cools fine while it is running. The compressor
already has a hard start kit on it. I have a couple of questions

*How can I determine weather the condenser fan or the compressor is
causing the breaker to trip?

Will a dirty condenser /debris or refrigerant charge contribute to the
breaker tripping?

What should I check from here?

Thanks for any help

Need a set of gages and an Amp Clamp. Or call someone who knows what they
are doing.- Hide quoted text -

Baum is too negative, the earlier suggestions were all worthwhile
following/investigating.
