The outside compresser should keep the indoor coil cold, and if it wasn't
doing that, there's no damage done by blowing air across warm coil and circulating it through your house. It could be bad to refrigerate the coil and not blow air across it -- it might "freeze" and break. Just ask your installer why the outdoor unit would be buzzing while the indoor unit worked -- why they are not wired to know that the other is down (like I think mine is). "Kerry" wrote in message om... I am hoping you can all help me. Here is the story.... We live in a 1.5 year old house. Our AC coils our in our atic, then we have the blower unit thing outdoors (sorry I don't know the real names of these things). We were away for the weekend and left the AC set at 85 degrees. It was a hot weekend and the outside temp got up over 100 (probably around 104). Anyway, when we returned home last night, our house was a very warm 87 degrees. The fan was blowing but no cold air was coming out. So I went outside and the outdoor portion of the AC unit was not on. I put my ear up to it and could hear a faint electical buzz. So it was getting power. Then I passed the condensation drain. The ground was wet, so the AC had worked properly at least sometime in the weekend. My next step was to go to the main breaker panel. Sure enough, the AC was tripped. I reset and it is working fine so far today. A few questions.... 1) What does the breaker control? The fan in the house was still running and the unit outside still seemed to have power (since I could hear the slight buzz). Does the breaker just control the coils? 2) What can cause the breaker to trip? And is that mean something really bad is wrong? 3) The fact that it tripped concerns me. Is this something that happens sometimes in really hot weather or is it more likely a problem with my AC? 4) I have no idea how long the fan in my house had been running before I came home. My guess is that it had been running for a long time (many hours if not a whole day) trying to cool the house without luck. Was that really bad for it? We let it rest overnight before we tried it this morning. Thanks all for the help. Out house is still under warranty, but since it hasn't tripped again, I am not sure what to do. Please advise.

Kerry could have been something un related to the a/c like i had one year on a sunday, a very small spider must have been in the wrong place at the wrong time... it was caught in the realay contacts to the compressor... blew the fuse and the compressor would not work.. i changed out the fuse and it still did not get current.. i checked the relay and found the contacts pitted pretty bad with 1/2 of a spider on it... the other half was burned up... i was lucky as the old relay was the type you could service.. i just turned the double sided relay over and used the other side of the contact and it worked fine.... |

So our breaker tripped again today. I guess we will have to leave it
off until it gets fixed. The air conditioning people said that it is usually a bad breaker. Do breakers really go bad that easily and often? Hopefully that is really all that it is. Any other things that can cause the breaker on the AC to trip (more than once)? Thanks again! Kerry (Kerry) wrote in message . com... I am hoping you can all help me. Here is the story....

What is amperage draw on outside unit label, and what size breaker its pretty common for the wrong breaker to be installed due to startup current |

if your pretty knowledgable w/ electrical then disconnect pwr theninspect the
contacts on the contactor 1 or more may have a dead spot or if it looks like it's gotten hot replace it. |
The slight buzzing was probably the relay in the operated state due the
the thermostat calling for cool. However, as there was no power to the outside unit (compressor/condenser), it couldn't run. As for why the breaker tripped, there might have been a brown out condition or a bunch of on-off-on-off power failures. Many newer units protect against both of there, however, there are probably some cheap, builder's special units that don't have the protection.
