water might have damaged the relay, control board or the fan. the fans usually have several windings and speeds. possable the ac speed is shorted out. call a teh in to diagnos.
The leak was due to the drain pipe that was wrapped around the room not being always level or downward allowing gravity to drain the water. It was backing up. That I have adjusted.
I am not sure that there are different speeds on the fan motor. There is a only transformer hooked to a relay and only 2 wires run to the fan. So the fan really could only have 2 modes of operation on and off.
There are only 2 relays on the circuit board, and one of them is for the kill switch and I'm guessing the other is for the fan control.
Since the fan turns on in heat mode, I would have to assume that the relay works. For some reason the relay isn't fired in AC mode.. and the outdoor fan and compressor come on when they are supposed to.
I want to avoid paying a tech to come out, charge labor and outlandish prices for a board I may be able to fix myself for a few dollars. My wife does not trust the local HVAC companies in this recession. We know a HVAC tech that charged his own parents excessive labor and uneeded parts so he could get a better commission. This was discovered when the tech was bragging to someone else about it.. and it got back to the parents.
