Mystery marks around fridge vent
My '65 Safari still has the original Dometic fridge which recently my brother and I worked on. I should mention I have also just finished a re-polish.
We removed the gas lines and thermocoupler, cleaned everything really well and re-installed.
I am not sure when the last time this fridge was run for any extended time. We fired it up on gas and let it run for a couple of days and it was working well. It rained for a bit and I noticed a strange discoloration over the vent with what looks like drip marks down the side of the trailer after the water had dried.
It took a little work but was able to polish out the discoloration. We camped last weekend and could not get the fridge to run cold. The pilot stayed on for a day or so. Now just back in town after a week away for work to find the same mysterious blemished over the vent again. Has anyone seen this before?
I am super puzzled...
