Condensation or Water under Refrigerator

[Pstan]

Just came back from a 8 week northern Florida trip. Popped off the panel below the refrigerator and noticed these condensation or water stains on the underside of the refrigerator housing, against the outer wall of the RV. See the 2 pictures.

Refrigerator was on the whole 8 weeks, mostly 120V but some propane. Freezer was typically +3 deg F to -12 deg F though for a short period while I was experimenting it got up to 14 deg F. Fridge was 32 to 40. I had 2 thermometers.

Norcold Polar 8 series, N8X. Installed in a CrossRoads Zinger 219RB. Nearest dealer is 250 miles away and not wanting to go that distance. It’s a year old end April this year so warranty may expire

Might this be just due to condensation? Certainly had some high humidity days in rain down there. Also the interior might have been a bit humid at times, with a few days of condensation on the inside of the windows on those cold mornings. I’m wondering if the cold outer sides of the refrigerator could cause condensation that may drip down.

Thoughts appreciated!!!

Trying to upload the pictures….looks like they are upside down for some reason.

Did you remove the outside panel and look at the rear of the refrigerator? Are there stains there too?

[Pstan]

No I didn’t observe any water stains there. However I think I did notice that the water catchment cup was totally full a few times, so maybe it had overflowed and seeped underneath. I siphoned it off a few times. I will try monitor that closely.

Good thought Davis.

My fridge had a little hose that drained excess water out the back side, and exited thru the floor onto the ground.
That hose has been known to get out of position, also it can get plugged.
I don't know if you have that or not.

If yours don’t have a drain hose. Purchase a piece of hose and some Gorilla Glue Epoxy Adhesive. Drill a hole in the catchment pan down low just big enough to push the hose in 1/4 inch. Use the Epoxy Adhesive to seal around the hose on both sides and run the hose below the floor where it can run out to the ground.

I had one that had the oval cup that dat in the coils I guess to help with evaporation. And one that had a plastic corrugated tube that ran out thru the vent door vent holes. Stuck out about a inch or so and had a plug/insert with holes to prevent bugs from entering. Sure sounds like it is draining inside and running down.
