HE220A1019 Whole House Humidifier

Thank-you for your response to my problem. I checked everything you suggested and all looks good except your idea of the fan spinning the right direction. I pulled the cover off and watched the fan spin while running. it is pulling air into itself instead of pushing air through the pad and into the plenum. I maybe wrong but it seems more likely that the fan should push pad moisture into the HVAC system. With that said how do I change the direction of the fan motor.... cannot be wired wrong on my end... they only have me break one side of the fan motor and run through the humidistat and sail switch. confused...

Is the unit on the return side or the supply side of your system ?
Is the system upflow or downflow?
You are right in your assumption about the air needing to be drawn through the Humidifier, now before changing the direction of the motor, we need to look at if the unit should be moved to the other duct, its alot less complicated, now when the fan comes on from the furnace, you have no trouble heating the house right ? if that is the case then moving the humidifier to the other duct would be your best bet, if your heating for some reason is only comming out of the return then yes you will need to change direction on the fan, but I would bet that moving it would do the trick for ya, I have only run into a couple of fans that actually were running the wrong way, thats why I asked, well anyways, you will need some tin, zip screws, tin snips, maybe a little more wire, let me know what ya find, I really appriciate your question back to me, anymore question please ask ! thanks again.

Why does my airvent whole house fan stop working intermittently?


if fan was able to run normally after a while, you may have problem with the motor starting capacitor, this gives the fan the needed kick to spin , when your fan stops working this may mean that the capacitor have already over heated, turning it off for a while will give it chance to cool off then start up again, have the capacitor checked and replaced immediately.

We do not know how to turn the whole house fan on. Does it work through the thermostat on the walll for the air- heat switch?


To turn on your whole house fan, got to you thermostat. Open the door and look for where it says fan, most will have a selector switch to select "auto" or "on". You want it "auto for it to work properly with your furnace and or central air. If you flip it to "on" it will run 24 hours a day none stop, warning this may shorten the life of your fan a little.

Ceiling fan


Sorry for the delay in response. Electrically, there should be no potential hazard since there would be no more "juice" running through the circuitry.
