New gas/absorption RV refrigerators all use a control board which needs a minimum 11.5VDC to operate. These control boards work all of the electric and LP heating functions of the unit, plus read the thermistor in the fridge section to maintain the set internal temperature and control the ice maker.......if you have one.
No 12VDC...........nothing happens! Be sure that you have connected a working 12VDC circuit to the white connection block that Dometic uses, generally found at the center of the of the outside rear access door of the fridge. Verify that the circuit does indeed have 12VDC. If not, look at your internal fuse panel for a blown fuse. It it does, look under the black cover for the fuse on the board.
