YOUR AC/Gas fidge has two fuses on lower circuit board
One 5A for AC electric heater element (Horizontal---center of board)
One 3A fo DC (Vertical--left side of board)

Your thermistor is functioning otherwise the AC would not properly cool
Only one thermostat and one thermistor.
Thermistor is the 'sensing' probe that the non-adjustable t-stat uses to control cooling cycles (turning heat source on/off be it AC or Gas)
Thermistor attached to far right cooling fin in food compartment.
AC Works...Gas doesn't
That suggests lower circuit board gas circuit is bad.
To test...
Check for DC Voltage at P3 plug Lower Board (upper right corner)
S/B DC Voltage between Terminal 1 (WHITE) and Terminal 2 (YELLOW) when on GAS and fridge is warm enough to call for cooling cycle
See pg 11

Thank you... I will check the gas circuit wiring tomorrow...
this an RM 2852 unit, but the board in it is like the one in the DM units with only 1 fuse...
it is my understanding that the only difference beteewn the RM and the DM units was the age of them (DM is newer), but otherwise identical... and it would stand to reason that a newer unit may be equipped with a newer style board.... BUT, maybe there is more of a difference than just age, and the DM board wont work in the RM unit??? who could definitely answer this question? thanks
