The fridge in my classic (Dometic 2807) has been problematic for the past several months. No light, no relight, endless check light.
This afternoon I removed the board and reignitor module.
I could not believe what I found! There were no fewer than 5 cold solder joints on the board, and darned near every crimp on spade connector was loose or not crimped!
I stripped, crimped, cleaned, and deoxited everything.....
Bam.... everything now works. I can switch from AC to gas and back with no check light! What a bummer I didn't spend the time before now!
If you are having issues, I strongly suggest the time spent with your soldering iron and a dozen new connectors.
Wahoo, consistently chilled libations without fear....
