Mach III plus 13.5 ac fan running backwards?
Hello all, My first trip out this year, my 2 yo ac was blowing through the filters and sucking through the vents. I was told it was probably a bad motor starter so I replaced it. Still blowin...

If it was mine...I would switch the wires around and it will run the other way.
I wouldn't tell somebody else to do that though.....
For Alternating Current motors there is no such thing as backwards wiring. There is no positive or negative, both wires are both positive AND negative (not the correct technical description) that alternate 60 cycles per second (dont wet pants if this is not technical enough...). Switch wires and the motor runs the same direction..
That is simply not correct or to be more accurate it is at best a half truth.
Most A/C motors and some DC motors have two windings.
Oh SOME A/C motors there is a terminal box and if you flip two wires in that box the motor turns the other way.
However said before I do not believe that is the O/P's problem
I think the motor and blower are operating properly but the plumbing is wrong.. a ceiling cover on backwards and possibly a baffle out of place. (Am sitting under a Coleman A/C as I type)
