Of course the best answer is pull the Amish fridge and install a Waeco compressor fridge. You can sell you old working fridge, someone will buy it.
A Waeco compressor is not to be confused with a residential compressor fridge. Waeco compressor fridges are duty cycle fridges and the compressors are super efficient so amp draw is less than a residential unit, substantially less and they operate on 110 or 12 volt power (no propane). As the fridge gets colder, the compressor adjusts to the cooler temps and cycles only when needed and at a lower draw.
Boaters have used them for years because the power is limited (no shore power when underway) and they don't have to be level to work (rough seas). In fact they run just fine up to 20 degrees out of plumb in any direction. Your Amish fridge won't.
Cost, about the same or less than an Amish fridge. You'd think RV builders would use them, just have not wised up yet. European builds have long ago.
