The other day on a hot night the power went out intermittently and I was only getting about half power... the AC would not run and the microwave was not working at full power. I flipped some circuit breakers figuring that there was a problem in my house, but then I discovered my neighbors had the same problem as a transformer had blown. After the electric company replaced it, my upstairs HVAC fan would did not work. The compressor would kick on, but the air would not blow through the ducts. The fan would not work if I set it to "on", turned on the AC or the heat. 1) I have two seperate systems for the upstairs and downstairs. The downstairs system works fine. 2) I spun the fan by hand it it spins freely. 3) I checked the capacitor, and it works fine. (I swapped it with the downstairs unit, which is identical). 4) I now want to check the contactor as described in this post below, but I do not know where the contactor is or how to get to it. www houserepairtalk com/f8/york-hvac-blower-not-working-871/ (replace spaces with . ) I have the York system described in this diagram: www yorkupg com/PDFFiles/035-20370-001-B-0405.pdf (replace spaces with . ) Any suggestions on how to find the contactor or what else I should try?
