Not enough six packs exist to bring that thing back to life. I sincerely appreciate all the kind and thoughtful beer consumption done by members of this forum on my Dometic's behalf.
The cooling unit is removed from the fridge box. It took less than two hours to pry it out. Would have been even less if I hadn't over-optimistically replaced the fridge mounting bolts/screws when I re-installed it.
I'm tempted to prop the old cooling unit upright and hook up the AC line directly to the heat element and play "Taps". But I'll let that pass. No looking back now.
I'm shopping for a replacement unit. Lots of good information on this forum and from vendors on how to perform the swap.
Any vendor advice or cautions are welcome either online or offline.
