sounds to me like you got quite a lot of condensation going on there! door gasket sealing tight? running the machine without a full load? or are you just "peaking in" alot? '>
the pan normally has to be emptied more often in humid weather too, I've had to empty mine once every two days lately, if it's inside you can run a dehumidifier also to dry up the air.

never had my pan fill up with any water at all...don't know what to tell you on this one.

johnieG is right! Look for gasket leakage, a hole in the cabinet, or someone looking in a lot.

Moisture quickly migrates to the dry air inside the box, quicker than "ambient" outside air around the box. Remember the old days when mom or dad would say "Close the door, your letting all the A/C out!". Well, what was really happening was the moisture was being sucked up by the cool dry air in the house, more than the heated air coming in.

Make sure all the door gaskets are good, and there are air no air leakage points. As a final suggestion, at the condensate drain, put a "P-trap". The trap will fill with water, sealing off moisture laden ambient air from coming in the condensate drain tube. Don't worry, it will drain.

I do know my Cavalier chest box dumps a lot of water, but it is outside, and the gaskets are all bad. I am in the procedd of restoring now, and should see a major reduction in condensate.
