Condensate problem

by Steve
(Greensboro, GA)

the drip pan under the airhandling unit keeps filling with condensate. i have cleaned the drain lines and traps, cleaned the condensate pump( which seemds to be functioning properly) No eve\idence of water in the air plenum but condensate is getting rrom the evaporator coil to the pan and missing the condensate collection system Any ideas???

It is a 2 ton Carrier Heat pump ( not Infinity)
