furnace leaking condensate
#7
  
I have a Goodman furnace that is leaking from the condensate collection plate.  i replaced the gasket last year and the leak stopped for a while but must have started leaking again sometime this winter.  Last week the leak shorted out the control board so while I was waiting for the part to come in I removed the old gasket and sealed with RTV silicone.  I cleaned the area well, applied a good size bead making circles around all of the screw holes, and waited 10 minutes before reattaching the collector plate to the furnace.  When then new control board came in I installed and started the furnace and everything looked good.  Yesterday I noticed water on the floor near the furnace and took the front cover off and found the same area leaking.
Did I not apply enough RTV
Should I remove the RTV and install another foam gasket
Should I use something other than RTV
Do I need to add RTV to the screws when I replace them?

I found this youtube video of the exact same problem I have.  https://www.youtube.com/watch?v=ASO13C8dyDg

I do not have a Goodman, so mine is set up slightly differently.  However, I had a problem with mine and furnaces are not my forte'.  I call a furnace repair specialist.  The man that came showed me that the issue was the water was not properly draining out the black hose.  He showed me how to disconnect the hose and clean it, by running a strong stream of hot water through it.  He then showed me to also take the apparatus the black hose connects to off the furnace, and do the same thing.  A lot of black crap came out of it. 

That furnace man got some new business off of showing me how to save $70 next time.   I passed his name around. 

I don't know if the above is relevant, but maybe it will help.
I tried not believing.  That did not work, so now I just believe

I was wondering something along the lines of what Cecil said. Is it possible the hose is clogged and causing a back up that is overflowing? I know before I realized how important that drain was, mine shut the furnace down completely...the tech showed me the mess.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.

Clean the ports, hoses and drains- all of them.

They get a lot of rusty gunk in them.

Move or protect the control board if possible for next time.

Condensate is a killer.

Mine was doing the same ... make sure those hose clamps are pushed back flush.  The nipple they are connected to is extremely short and there is not a "nub" on it for the clamp to sit behind.  If the clamp is angled in any way, it actually opens up the rubber pipe on the bottom.

Much of what has been said is on track. Carefully inspect the collecter box for cracks while it is off. Strong light and magnifying glass if necessary. The cracks can open when hot. Also inspect the hoses for cracks and splits. A new gasket wouldn't hurt, I would give RTV about a half hour before assembling and a couple hours before starting the unit.

Common decency is as rare as common sense. I figure there was only a finite amount of both made and its getting shared out among too many folks.
