Near your breaker panel if you have a set of generator switches, be sure they are all set in the same position ("Line"). Now at the breaker panel(s) itself push each breaker's handle [except the main breaker], one by one, first VERY forcefully Off (hear any click?) and then after a second or two push it firmly to On. Did any breaker seem to not stay firmly On then (or seem to make a buzz or hum noise for a moment)?
