So, last week, we found that the air conditioner wasn't working. The inside blower was working, but it was blowing room-temperature air.
I tracked the problem down to the big (50 A) circuit breaker being blown. I switched it back, and it immediately blew again (well, in about a second) and I heard a noise from the outside A/C unit (on the other side of the house, so I couldn't see it.)
So I got my wife to do the circuit breaker again while I was watching the outside unit. The motor glowed or sparked or something -- light came out. I wasn't that close, so I'm not sure exactly which. I'm also note sure what the fan did.
It was raining, so I left things off, went inside.
I came back out the next day, sunny skies, and tried it again, this time being close to the unit so I could see exactly what happened. And it started up fine, no problems. Turning it off again, I saw that the fan spun pretty freely -- it doesn't seem to have problems with the bearings (as I've had in other appliances.)
So now it seems fine. But I'm reluctant to actually turn it on. Yes, the circuit breakers will protect me from future problems, but I don't like relying on it.
I'm not much of a handyman, but I could replace the motor and/or condensor easily enough -- it's easily accessible. And of course I'll have everything off and the circuit breaker off if I try. This is about 10 years old, and living in Texas, it gets a lot of use.
But should I? Or should I just check that water isn't getting in somewhere?
