    Hi Kath,
    Sorry to heard about your air conditioner problem. I would suggest letting the unit sit for a while after resetting it, then turn it back onto a lower setting. The hot days that we have been having are placing quite a strain on many AC units, so they may have a hard time keeping up with the heat if they are set to full cooling. If the unit continues to trip off then go over the list in the article above which may help you diagnose the problem.

    I have an air conditioner unit that vents with a hose to the window. It worked great, but has now shut off. I reset the unit but it does not go on. Whats up with this?

    Hi Waverly,
    When a circuit does not have power I begin by checking by checking for a tripped circuit breaker. If that is not the problem then I identify the circuit at the panel and shut it off and begin checking in the junction boxes of the outlets to look for a bad connection. See the information in the Troubleshooting Section for more information.
