Does anyone know if the coil cabinet(lower drain pan) on a York G1HD36S horizontal coil can be replaced? The cabinet is leaking condensate from the front corners of the cabinet near the drain lines. It's not coming from the drain connections.

I have seen one web sight that shows part numbers for cabinet replacement parts but don't know if it's practical
to attempt to rebuild the cabinet without opening the lineset.

The system is about 6-7 years old.

Thanks
