The evaporator coil for my daughter's central air conditioning is leaking condensate on the basement floor. The drain line is unobstructed and also flowing some water.
This is a Carrier unit and it was installed with the access panel less than a foot from the basement wall, presumably because the refrigerant connections are right below the panel and it's a direct shot from there to the outdoor unit. Whatever, it was a real pleasure taking the panel off and getting it back on.
Did not see anything obvious with the panel off, but there wasn't much that could be seen from back there. It looks like the condensate tray is on the opposite side of the unit where there is no panel.
Noticed a small cover on one corner. Behind the cover was a drain pipe with a rubber plug in it, from the factory it appears. What is the purpose of this other drain connection? Would it help to also run a drain from it?
I'm guessing that the condensate tray may have a leak in it, but I don't see any easy way of accessing it short of cutting a hole in the housing. I don't know what these trays are made of or if they are are prone to rusting out.
What can you suggest?
