Great idea Chicago man. Here are some tweaks that have actually caused the heater to come on (at 79 deg).

Submerged the coils in a tall, long tray filled with water.

Wrapped the coils around the freezer element on top and laid a gel-cool bag on it to keep constant contact with the cold element.

This is working like a champ. I am surprised that a DIY project of mine is actually working. I have not started to dial the fridge thermostat back now a little to see where the heater will turn off. I suspect this will take a few days to get right.

Told the mortgage company to buzz off this month - ordered an aquacontroller for tomorrow and will set up the control to turn off the fridge - not the pump if the temp gets below 77. Thanks to everyone for their input.
