New dometic 2852 issues and comments

I just replaced my old and original refrigerator, the Dometic 2852 with a brand new one, with the same model number, 2852. My old frig had the Climate Control Switch and the new frig does not. It worked fine until it got pretty humid and the fins where dripping alot of water. The pan collected the water and then dripped into the cup which was overflowing into the refrig. I went out side, removed the frig. vent cover, inspected the drain tube, blew into it and water blubbled out of the cup. So I knew it wasn't plugged. Water then stated dripping into the cup and draining thru, but never out of the end of the drain tube. Eventually it filled the cup and started draining inside the frig.
(I did the install my self with the help of a qualified rv tech)

Any thoughts on what's going on?

I also watched video from the Ford's RV Frig Tech website and they say to put a trap in the condensation tube before letting it drain outside. This way water will stop any air from getting inside the frig cabinet. Anybody try that?

Last question about the thermister, how does it work and what does it do? Does the clip just slide up and down on the bulb or does the bulb/wire pull something inside?

thanks in advance

UPATE, I just got brave and went outside and removed the refrig exterior cover and pulled slowly on the drain tube till I felt some resistance. I pulled an additional 12" of black drain hose. Water came running out. I then blew into the hose and my wife could here the air movement inside the refrigerator, so I know that everything is still connected. So the reason the water was leaking into the frig. was that there was a kink in the drain line which was acting like a p-trap but not low enough for the water to drain out the tube but drain back into the frig thru the cup.

To reinstall the cover with tube protruding outside, I did put another kink or p-trap into the line, but it is much lower and the outflow is way below the cup inside the frig so it won't back up.

Question: should I cut the hose and remove the p-trap? (I do have the drain plug installed)
