It is necessary to inspect the entire fridge for air leaks into the box. Air leaks will be the biggest contributor to the humidity inside the box.
I have the 3/4 in foam insulation board and tape.
Upon recent recommendations, I will need plumber's clay and silver foil too.
Yup StainlessLobster waiting to be installed. Saving up installing it until I get the collector box and vent hose to remove the heat from the area behind the fridge. I think it will take all day to do all the modifications.
How do you feel about installing a fan inside the box?
Also, has the discussion of the tray 'in or out' been resolved?
Also, the placement of the temp sensor bulb in the main box?
Understand, I am living aboard so the door opening and closing is similar to that of a house fridge. That too is adding to the box humidity.
I will be leaving the boat for 2 months so I shall wait until I return to modify the fridge. It would be best to be onboard to monitor the fridge rather than install it and walk away for 2 months. Once I build confidence in all the modifications then, I will feel more confident with the 'system.'
