Refrigerator quit

[Stephen Quandt]

My coach has a Dometic NDR-1292 refrigerator / freezer unit. It has been
running perfectly since the end of Feb when I installed a new thermocouple in it
until last Thursday when it abruptly quit.

It cycles between gas and electric with no problem both produce heat. There are
no signs of ammonia leak, no loud gurgles to indicate a blockage. All the fuses
are good. The resistance on the temperature sensor tell me that it is closed
calling for cooling. I am stumped!
