Condensate leak at pan/plastic interface


Hi,
I have a Trane 2 1/2 ton unit.

I have a condensate leak right at the point the metal drip pan interfaces with a plastic transition piece to the condensate drain. It is in the corner. It does not appear to be rusted, but the gasket or sealant has failed in that corner (I think gasket).

I can't figure out how to get the plastic piece out in order to remove the entre pan assembly. Any thoughts.

Any other ideas to stop the leak.

Thank you

Dry it, clean it with steel wool and seal the leak with DAP high quality plumbing silicone. Or RTV silicone if you have it.

Do it on a day when it does not run as any water drops may cause the silicone to not cure or stick. Use a hair dryer or heat gun to get rid of the water first.

The picture is too dark, can not see anything. the bottom line is, you should not see water anywhere, if you see water, you have a problem.

I used the silicone and it seems to have resolved the issue. Thank you for the suggestion.

Just curious, there is an absorbent pad below the metal tray and seems to be always damp. It catches small drippings from the bottom of the pan that fall from water condensing under the metal pan. I guess that is the way its suppose to be.

It probably is insulation to prevent cooling loss.

It should dry up once the leak is stopped.
