Sounds like the pushbutton unit is flaky - a common problem on older 123 chassis (mine does that too). A simple trick which works most of the time is to press one of the other buttons (AC or bi-level) then press EC, and the fan should kick on. If not, you either have other problems, or the pushbutton unit is really bad. You can either attempt to open it up & resolder (fixes things maybe half the time), or buy a rebuilt unit (easy to swap out yourself but will cost ~$250 for the part.)
Good luck,
