The special sauce is water, ammonia, and hydrogen at around 400 psi, plus
an anticorrosive powder.  The water/ammonia mixture boils in a boiler,
discharging ammonia gas which travels up to the upper condenser fins to
begin the cooling cycle.

The boiler gets its heat from the flame or from either of two electric
heating elements -- if any one of the three cools the fridge, that says the
cooling unit is working correctly and the problem is in a faulty heat
source.
