When DC mode starts and quits after a few seconds, it's almost always voltage drop. The DC heater draws a lot of current, and thin wiring or a weak connection can't keep up. Measure the voltage at the fridge with the DC heater on. DC mode is meant for driving, with the engine charging. Send us your model and we'll help.
