OK thanks all. I will try what opnspaces posted from the Samsung website. I tried flipping the circuit breaker to the fridge, but that did not work. Don't know how the wiring works, but the invertor sent power to the fridge and it kept working. Its wired someway that the fridge works while driving down the road. The tow vehicle keeps the battery charged and the invertor keeps power to the fridge. I assume to make that stop, I need flip the circuit breaker to the Invertor and then pull the 15 or 20 amp fuse to the invertor. To complicated. I just want to shut off the fridge and still have power in the rig...
