    Not always easy to see on the air handlers.

    Best to ask them, if they wired it up.

    Its the goodman AEPF303616 variable speed air handler. I kinda wish I could check it myself. I asked them if the thermostat was hooked up for dehum before they left the first time and they said Yeeeah lol

    Ok I'm not sure if they set the CFM but on the interface module of the thermostat, nothing is hooked to the DHM 1 or 2. I take it that means its not hooked up correct?

    Nope. It can't control blower speed without them being wired in.

    When you talk to them.
    Explain everything you want it to do, to them.

    They may not understand what you want it to do. Since they never used this stat before.

    Is this a A/C only system or heat pump? Single stage or two stage?

    If it's two stage, hope they wired up the 2nd stage up right.

    I've had 2 Goodman variable speed air handlers do what you describe. I ended up finding an undocumented factory installed jumper wire on the control board causing the problem. Maybe the 2 I found were not isolated cases...
    If more government is the answer, then it's a really stupid question.

    Do you have electric heat back up on it? Staged?

    Also, not sure where you out of, if you do have electric heat back up and in a cold climite, they hook up an outdoor sensor?

    Im in SE GA hot climate. They came by this morning and hooked up a wire to the DHM 1, but it still doesn't seem like the air handler is slowing down for lowering the humidity. He wasn't sure if he needed the jumper from R to the 1s he said. Does he?

    Yes, the tech needs to add a jumper from one of the R's down to DHUM1, then DHUM2 to the air handler.

    So do you have back up heat?
