    We have gotten a tremendous amount of rain here in VA over the past two weeks. Long story short our AC/Furnace fuse started to trip about 5 days ago. The ac unit would start working then shut off after 30 minutes. I went downstairs and looked at the furnace air vent and the air filter was not on it. That was my fault because I had been down there a couple of weeks ago and forgot to put it back on.....


    Rain subsided a little bit yesterday and the AC unit has stayed working all day today.

    I'm lost.....moisture in the system? AC unit is 8 years old and is clean/undamaged.

    Thanks for any tips.

    Ours did that. We thought the compressor was giving out. Ended up being a relay or some cheap electronic issue. Fixed in a single $75.00 service call.

    Is there an outside fuse for your AC? I've seen where earwigs have packed into the outside box and shorted things out. [insert gagging smiley here]

    May be a weak breaker, and they start tripping more the weaker they get. May try getting a new breaker, they are cheap.

    You might have some bare wires that are causing a short when getting wet. Was there any standing water around the unit?

    If it happened with no rain I would say potential capacitor failure.
