Protecting absorption refrigerators PCB

Better to protect the PCB from getting wet at all.

Yeah but I can't choose the weather. I'm next to the Pacific Ocean winds can typically get to be around 40 to 60 mph. A number of years ago there was a storm and the winds got up to 120 mph flip over a few 5th wheels I guess weren't tied down good enough

I'm planning on sealing the cover perhaps with some sort of silicon. I'm not certain the existing pcb cover is good enough if ~50+ mph winds are going in all directions up, down, sideways, underneath and over the top of the RV I think the rain is being forced through the frig vent and ends up effecting the PCB.

I was thinking of installing some sort of cover over the vent but I'm not always around the RV to remove a cover when unneeded. Absorption frigs need to be level and won't operate correctly without enough air flow.

I looked around for an electric but all are either too small or too large. The frig is mounted off the floor near a wheel well so it would be impossible to somehow mount one on the floor.
Anyway I'll try to devise a internal cover over the existing pcb cover that won't restrict air flow.

The PCB, even a small amount of water or moisture can prevent them from working. I was hoping as an added protection the conformal coating will prevent problems in case the PCB become wet again. However I'm uncertain how well a coating would work to protect the PCB plugs contacts and wires.

Currently the frig won't turn on as I can see a very small amount of some moisture one to two drips from the bottom. It appears moisture somehow got inside onto the other side of the PCB between the PCB and what it's mounted to.

I'm hoping it will start working again once the weather gets better and it has a chance to dry out.

I think absorption frigs are great for traveling but they can potentially become a nuisance for full timing and cost more to run than an electric.
