Bryant HP, 13 yrs old, comfort maker AH 3 yrs old. I keep the dial on “auto” and yesterday the cool side kicked in and seems to be doing a great job. I have a Trane electronic air filter mounted under the AH. It was flashing like a police vehicle, alternating yellow 3 times, then Red 3 times and repeating. It would not reset, so took it apart, the filters were wet, the electronic grid was wet, the course filter was wet, the control head was wet. looked under to see the “A” coil, it was pretty wet also. First thing came to mind was, the condensate drain was plugged. No, it runs fast and clean. Flushed it anyway again this morning. Dried off all the filters and plugged it back in, worked normal for about 2 cycles then the lights are flashing again, everything is wet. Had service about 2 weeks ago, where they replaced the AH fan motor, the defrost board and bypassed the VPS switch (vapor pressure switch). It works good, but don’t know why all this water is all over the filters.
P.S. the pan under the “A” coil is damp, not excessive water etc. Poured a cup of water in that pan, it ran out the condensate line about 30 seconds later.
