The Amish coils still heat with propane. They mount on the refrigerator the same way the old coils mounted. Also, make sure the black and white wire in the control box that go to the cooling fans are properly connected. Even though the fans are 12v DC if the wires are hooked up wrong then the fans won't work. Mine were hooked up backwards and when I got the new Amish coils there was a wiring schematic with it. I have no idea how they got hooked up backwards and how long they had been that way. The recall is a joke but don't throw the refrigerator away and pay $4k for a new one. The Amish coils cost me $1075.00.
I used a motorcycle jack, wrapped tape around the wheels to protect the floor, set it in front of the fridge after taking off the doors, and removing the interior shelves, and mounting screws. Then I went outside and disconnected the gas lines and unplugged the fridge. I had an ice maker that never worked so I also had to unhook the water lines. Then I shoved the fridge out of the opening until I could go insided and pull it out.
I rolled it into the center of the kitchen and raised it up until it touched the ceiling which made it stable. I took the four screws out of the old coils, threw them out in the yard, cleaned the caulking off as instructed, put the new caulking in as instructed, mounted the new coils in place, put the screws back in, sealed it with the tape provided and then before I put it back in the opening I cleaned out all the dust and replaced the fiberglass insulation with aluminum coated styrofoam board cut to fit. Lot neater. Then I slid it in, hooked up the gas lines, plugged it in, and turned it on. It now cools on #5 instead of #9. I took the worthless Ice Maker out. Trays work.
Hope everyone finds this useful. The Norcold solution wasn't a fix, it was a removal of liability. No matter how many times you have the sensor replaced the fridge will not stop overheating and if you bypass the sensor and your rig catches on fire, it's your fault, not Norcolds.
