When in Florida in 2010 was up in the panhandle and the humidity was almost 90%. I had the fan in the auto position on the thermostat and we had Dometic Penguin units. After running the A/C for a while water started dripping out of unit onto the floor. Asked my brother in law who was traveling with us in his RV and he had the same thing happening to him. He went and read the instructions for the Dometic and it was mentioned that in high humid areas that water/ humidity, could accumulate on the evaporator, freeze and then thaw fast enough for water to drip from the A/C unit. The instructions were run the fan on high to stop the water dripping. Did just that. Took the thermostat off auto for the fan and set the fan on HIGH. It worked. No more drip. Apparently you need more air volume moving across the evaporator to stop the water from dripping from the unit. Just thought I would share what worked for us. Good luck!

This is not from rain, it's condensation when I run the unit. It's on Auto and I live in Florida so I will put it on high fan and see what happens. This may be it!!!!! Thank you so much for giving me a new direction because I have cleaned the drip pan several times already. How long did you run high fan?

The plenium I speak of is merely a sheet metal or nonmetallic deflector/barrier to keep chilled air and warm return air totally separate. If it has any gaps, cracks or holes between chilled air and warm return air, seal them with metallic duct tape.

You may download the service manual for YOUR air conditioner from https://bryantrv.com/docs.html#airconditioner

Making the holes in the drip pan bigger worked!!! Thanks everyone, I leaned a lot!

Check the evaporator pan drain hole.
Remove the inside air diffuser and tighten each of the 4 hold down bolts 1/2 to 1 full turn and no more. You do not want to over compress the gasket.

If it still leaks water in, you will need to remove the unit and thoroughly clean it. When re-installing, use a new gasket and tighten per the manufacturer's instructions, but to not compress the gasket more than 1/2 of its original thickness. DO NOT use any caulk on the A/C gasket. It has a sticky side, and this goes against the unit to hold it in place while positioning the unit.

Wow saw your callsign, you are VERY close to me, probably the same month but different state obviously.. KE6AVG. Sadly I let mine expire.

Start with the easy stuff...

When is the last time you clean the evaporator coil and tray in the AC?

Check your A/C drip pan (tray), it's most likely clogged and causing condensation to drip back into the Rv. Happened to me after cleaning my a/c coils.

I drilled the hole in the tray a little larger to help prevent blockage in the future. It does not take much debris to clog the exit hold causing condensation to quickly fill the pan (tray) which then allows it to drip back inside.

Here is a pic of the drip tray on my Coleman Mach a/c. Yours may be different. In the second photo you can see where I drilled a larger hole for better drainage.

Note: just noticed this thread was from May. Hope this helps someone in the future.
