Fan motor seems to be running backwards. Installed in 1999.Always maintaned. Overall worked OK until this past year. Many problems with water leakage. When I opened and checked fan direction, it was moving in the direction to **** air from the furnace side instead of pushing the moist air into the ductwork. The leakage seemed to support this problem as it was water build up in the fan assembly side. All hoses and filters have been checked and cleaned. Any suggestions? Am I not understanding this? Its a AC motor so the wiring shouldn't matter, but I did confirm and swap the motor wires just in case. It has worked, albeit tempormentally for all these years, so I can't figure how it could jhave always ran backwards to what I would assume is the correct direction

Answers & Comments
The fan on the model 700 does rotate backwards compared to your typical fan operation. This fan will pull air from the duct verses pushing air into the duct. There are several things that may cause your humidifier to leak. The most known reason for leaking is the water panel/filter is not being changed frequently enough which should be at least once every heating season. You also want to confirm that you are utilizing an authentic Aprilaire water panel.
- Is the Feed Tube tightened or is there a crack in the tube?
· Is the base of the scale control insert sitting firmly in the drain spud at the base of the housing?· Does the bottom of the scale control insert have a taper to it to direct water to the drain spud?
· Is the Scale control insert positioned correctly? The scale control insert has a front and a back. The back of the water distribution tray has an indentation in it to allow for clearance of the nozzle, which is attached to the top of the base. If reversed, and forced into place, the water distribution tray will break off the nozzle attached to the water feed tube and potentially the housing, causing water to leak
· Is there a gap between the top of the water panel and the water distribution tray for air to go through?
· Is the colored dot on the water panel, up?
· Are there signs of entrainment? Mineral build-up on fan blade, shroud, inside of cover?
