Greetings ... I have a different refrigerator problem. My Norcold 1210 refrigerator cools fine & the freezer works well, but the entire unit will randomly shut off. Most of the time it will immediately turn right back on. There has been a couple of instances where I can hear it trying to start up but does not. I'd have to let it sit for a short period of time before it will turn back on. It does not matter if it is running on AC or propane. Before our last extended trip where this issue popped up, I cold hear a fan whining at times, & I'm wondering if it could be the unit's cooling fan(s), but the fact that it properly cools when it is running has me baffled. On our trip a tech replaced the main board, but it did not fix the issue. I'd appreciate having a better idea of what might be the issue before I proceed. Are the internal fan units easily accessible? Would a solar powered fan vent cover work? Thanks!
