    Last year my daughter’s AC in her condo was not working. So Ihad her check her breaker box and switch it off then on. That did the trick and had no issues until yesterday.

    It happened again, so she went to switch on and off the breaker, AC did not turn on. Switched it on and off again, this time she pushed the button for the AFCI and switched it on and off. The AC turned on. Should she check the fuses too? Or could it be something else?

    Do you think maybe the fuses are starting to go out?

    It could very well be the capacitor. You’ll need someone with just a few tools, and it’s usually above the compressor–it looks like an orange juice can and costs $25-$35 to replace. Capacitors typically don’t fade though, they fail. My thought is fresh current could close it temporarily then when it gets hot it opens and disconnects. Obviously, throw the breaker when working on the unit, and discharge the capacitor first by putting a voltmeter between the terminals to check for any remaining voltage, then cross them with a well insulated screwdriver and heavy glove.

    Another possibility is a dirty condensor. Easily cleaned, locate the outside part of the a/c unit and look inside and you will see it inside the housing. Use a garden hose and clean it thoroughly. Doesn’t cost anything but a few minutes and some water.

    And “thoroughly” means up to 10 minutes with a strong stream. You’ll see the dirt come out under the unit. The condensor looks like a radiator, and when complete you should be able to see through it. But, unless it’s completely plugged, I would guess that’s not the prime source for the electrical disconnecting. That, any inside coils that would be in your inside system (wire brush and vacuum cleaner to clean the coils), and your air filters need to be cleaned a lot more frequently than most people do.

    Also, look for frost or ice on the copper line coming out of your outside unit. If you see that, it indicates a bottleneck somewhere, see above for cleaning.
