I recently had an issue on my 2015 Landmark where the residential refrigerator would shut off by itself. It was the only piece of equipment in the RV that wasn't working while on 120V shore power. The issue was difficult to diagnose because the power would come back on it's own before you could run through all of the troubleshooting steps.
The first time it happened, I focused on checking the fuse panel and then wiring under the slide to see if I could find the issue. As I was pondering what to check next, the power came back on it's own after I flipped all of the breakers off and then back on to cycle power within the system. Magically, the refrigerator power came on.
The second time the refrigerator cut out, my wife was bringing the slide in to prepare for a move. I had her open the slide up and I began to troubleshoot again. I did see that the work box furthest toward the front of the trailer, under the kitchen slide, provides power to the microwave and refrigerator. The microwave line was hot, but the refrigerator line was dead, so the issue was inside the RV with no power coming out. We decided to move to the new campground with no power for our refrigerator. It was cooler outside, so we figured the fridge would hold until we got to our next stop.
Once we arrived, the refrigerator came on without any issue, so I had to wait for the issue to show itself again. I was lucky to be doing some work in the morning and I was looking at the refrigerator as the power went out. I already had the access cover for the transfer switch for the inverter open with wires exposed, my multimeter was set up and just needed to be turned on in the bay, and I was able to verify that 120V power was coming into the transfer switch, but no power was coming out. I then turned on the inverter, and I still couldn't get any 120V power on the outbound let of the switch.
I ordered and installed a new Magnum CSW-TS15 Transfer Switch. As I installed the switch, I also found that my deep-cycle batteries were failing too. They showed 13.2V, but they weren't holding a charge. I replaced them as well and we haven't had any issues with the refrigerator since.
