The heater is separate from the ice maker- it keeps the water line from freezing. It is the only temperature sensitive item I can think of, and it draws a small bit of current, which could make a bad connection show up.
The problem is common when the outside temperature drops below 28°F
and the "WEAK AMMONIA SOLUTION" freezes.
I'll use the graphic that I made over a decade ago-

from my page at http://bryantrv.com/reefer.html
BTW - I notice you are in DeLand Florida where "severe cold" is temperatures below 55°F. To those of us who 'winter' near the Cheddar Curtain, 40°F is a heat wave.
I am fully aware of how an absorption refrigerator works, and can assure you that 1, it is not "very common", and 2, the weak solution will not freeze at 28 degrees. I have over 15 years and 1/2 million miles of RVing experience, including Wisconsin in December.

Amazingly, my refrigerator worked fine in below zero weather (I was going through a 40# cylinder every other day though).
Last- can you explain any possible way that a freezing "weak solution" can shut the power off?
