Reset breakers, house power still out.

[TheGrooveking]

Hopefully when the breaker died it didn't single phase( allowed only one of the 110 lines to pass thru) and burn your compressor/fan.

That is a single phase service, single phasing is when 1 leg of a 3 Ø circuit is lost. BTW, single pole contactors are common on HVAC equipment which means they only switch 1 leg of the 240V supply.

Pull the disconect out by the AC unit and pull the panel off of it . The capacitor is going to be a round cylinder with 3-4 wires going to the top of it if the top is rounded up and not flat and rexessed into the top then you have a blown capacitor . The only way you are going to get one on the 4th of July will be to call an AC guy as all the supply houses will be closed " trust me I are an AC guy and although I am working tomorrow all the supply houses here are closed " .


Oh yeah dont touch any of the contacts on the capacitor without first shorting them out with a screwdriver as they can hold up to 440 volts in a residential unit and you will barely remember what happened when " if " you wake up .

Only the top switch on that main breaker is on. The lower half looks like it is still off.....

I wouldn't be telling people that without telling them to pull the disconnect first.

Sometimes, troubleshooting stuff is best left to the pros. The OP in this case has difficulties with simply resetting a circuit breaker.

Not sure if basic internet electrical HVAC troubleshooting is something I would provide.

And a good AC guy will have a few spare parts for emergencies.

I agree that leaving stuff to the pros is the best idea if your not sure of something. However it wasn't so much resetting a breaker obviously he did that correctly, it just doesn't do any good if the main is shot.

Yes you are correct in regards to it being called single phase service, but if you look at the two legs on a scope you will see they are not in phase with each other, hence two 110 lines equalling 220 volt because they are opposing each other in the sine wave. You are correct in regards to some equipment switching only one leg of a 220 circuit(I find that to personally be a cheap stupid unsafe way to build a piece of equipment).

As it was late and I was very tired when I posted, I mixed up loosing one leg and loosing the neutral, which I've seen burn a lot of stuff up and even cause fires. THanks for the correction, I'd rather be wrong than to have other learn/use incorrect information.

They do it that way because there is a heater in the compressor that they want to run all the time. It keeps the refrigerant vaporized so that it doesn't turn to liquid and slug the compressor on start-up.

Ya gotta read a little more in depth Danski and yes theres at least 40 capacitors on my service truck right now . My point was the only way the OP was going to get one on a holiday weekend was to call a service tech out .
