My air conditioning unit won't start and keeps tripping the circuit
breaker. When I try to reset it with the A/C on, the fan will move
just slightly and then the breaker trips. I can see nothing physically
wrong with it or the metal bars it connects to. With the A/C off, it
seems to switch on and off normally. I suspect and fear that there
may be a problem with the compressor or something else in the unit.
But if the breaker is bad, I can replace it myself and save a service
call. Problem is that I'm not sure how to test it. Any help or
advise would be appreciated.
You could temporarily connect the wire(s) for you air conditioner to another
breaker of the same amperage, in the panel and see if it trips, although it
doesn't sound like a circuit breaker problem to me
Odds are you need a pro to look at the unit. The breaker could go bad,
especially since your FORCING a dead short across it repeatedly.
Looking at the breaker and trying to figure out what is wrong on the other
end is like looking at your tires when the car will not run.1
The day was hot, and demand for Stormin Mormin was running high. The
days call was normal: No cooling. Stormin Mormin arrived on site, and
immediately inspected the thermosat. Then he scratched his head, and
looked at the thermostat. Then he scratched his head and looked at the
Finally, it came to him. The problem must be the 'capacitor thing'. And
so, he pulled a used capacitor from his box of things, and crammed it
in as best he could.
Sure, it was the wrong size; both physically and electrically, but hey;
it's just a capacitor after all.
Stormin Mormin then hurried off to the breaker panel, where he sawed up
a circuit breaker and crammed it into place. No, the circuit breaker
had nothing to do with the service call, but the customer asked for it
to be changed, and being the 'swell' guy he is, he agreed to do the
work. After all, its not like he was licensed or insured to do any of
the work he was there to do in the first place, so what difference did
a bit more quackery make? Besides, it's not as if Stormin Mormin had to
actually live in the house he was converting into a fire hazard.
And so, he hurried off to home depot to find the perfect circuit
breaker. He picked the one he thought was the prettiest, and hurried
back to the job.
And then he found out that it too, was the wrong size, both physically
and electrically. But, nothing a chop here and a trim there cant take
care of! After all - what's a quarter inch of plastic gonna do to help
or hurt anything?
Then Stormin Mormin turned everything on, over charged the customer,
and then ran back to usenet to brag to everyone about his exciting
(The preceeding story is quite true. Don't believe it? Follow the below
