Ice box to fridge conversion condensation

[fred1diver]

Hey everyone, about a year and a half ago I converted my ice box to a fridge on my Pearson 30
Works great, except for the counter always being wet from condensation
The top of the ice box isn’t insulated,.
I would like to remedy that before I change the counter tops, but I am not sure how thick the insulation should be
Any ideas???
Thanks in advance
Fred

You will need to stop cold air leaking.

You look at fridge doors and some have 1 to 2" of closed cell foam plus all of the joints are sealed.

You could try setting a 1" piece of foam in the top of the cooler big enough to fit snug to the walls to test if the thickness is enough to stop condensation on the couter top.

I have a top load fridge on my O’Day 322…and I can get some condensation around the edges of the door…

I cut a piece of Reflectix (thin foil-sided bubble wrap) to fit inside the box, and I keep that in the fridge when I am not using it. It adds a little bit of insulation and helps with the condensation. But my fridge lid IS insulated. I expect in my case the Reflectix cuts down the air gap around the door.

Cheap and easy to try.

As thick as you can to include the lid

This.

Condensation outside the box is not caused by air leaks, it is caused by inadequate insulation. Condensation and icing on the evaporator is caused by air leaks and normal operations.

Blue foam insulation will work. Some hardware stores will sell small pieces of foam so it is not necessary to purchase a 2'x8' sheet.

I found some nice 1 inch xps foam
What do you all recommend to fasten it to the underside of the counter / ice box top?
