Rooftop Air-conditioner dripping then pouring water...help

Can anyone help me troubleshoot? Dealer can't get us in for 2 weeks.

The A/C was running on max because it's been in the 90s and humid here, and started dripping quite a bit of water. So I turned it off, and BOOM! Water poured out! :E

I googled to see potential culprits and the consensus seemed to be a clogged drain, so I sent my hubby on the rooftop to see if there was a drain and if it was clogged. He said he couldn't even find a drain. LOL Neither of us is too mechanically inclined.

So, is there anything else anyone can suggest, bearing in mind that I don't want to attempt anything that could result in us getting electrocuted! :D Thanks!

    Here is a neat pictorial that might help...


    When it is very humid these air conditioners will tend to freeze up...

  • Send hubby back up on the roof.

    He has to unscrew the cover off the RTAC. At the rear of the RTAC he will find a drip pan. It is usually white in color and has a couple holes in the bottom. Trouble is, the holes are usually pretty small and can get plugged up by the least little bit. I personally recommend that you drill those holes larger, but in the short term, unclog the holes, check for any adjacent debris, and then reinstall. This should solve your water in the coach problem until the next time the holes plug up again.
