I have 3 Dometic Penguin a/c & heat pump systems on my roof. They all have a drian system that collects the water from the evaporator and drains it out the both sides into some pipes on my roof. It appears that my front A/C may have a leaking catch pan inside the unit. It is a plastic pan that the evaporator sits in. When water collects in the pan it is suppose to run out the side drains. But when I pour water directly into the pan, some of the water ends up inside the metal base unit of the AC. So if enough water collects there it eventually leaks into the coach. My question is, has anyone found a way short of replacing the whole AC unit, to fix this problem. It looks like it would be near impossible to remove the evaporator to get to the plastic pan. It may be possible if the whole thing was completely disassembled. The other thing to keep in mind, these units are almost 12 years old. So I wonder what the payoff would be in trying to fix 1 that old, versus just replacing it.

Comments welcomed.
