The area below the fridge
vent covers allowed water to leak onto the wood below the fridge. I removed the counter top and fridge, and replaced all the wood in the cabinet. I painted the wood with mould resistant paint
so that there was a layer of protection against future rot.
I also bought some 2" wide aluminum strips from Home Depot and used 3M 4200 adhesive to create a "water dam" at the bottom of each vent opening. Since making these changes, there's been no more water entering in the fridge area.
I now use a 12V DC compressor fridge rather than a 3-way absorption fridge. I completely removed the fridge propane
line and utilized the existing DC cable. I relocated the AC plug for the compression fridge to be an internal additional power outlet on the right side of the main cabinet.
See attached pictures. The water dam is the silver aluminum strip glued to the bottom of each vent opening:
