The fridge won't work

Did the residential replacement with a 10 ft^3 Magic Chef model from Home Depot three years ago and never looked back. The refrigerator has thinner walls, better insulation, a colder freezer, auto defrost, and more efficient interior storage space. Food and drinks stay cold while we are OTR even if the door is opened once or twice. Previously frozen blue ice blocks help there as well. I use a remote read thermometer to keep tabs on the inside temperature. If it gets too warm I just run the generator for 30 minutes. That cools the food and exercises the genset as well. I read the skimpy manual that came with the refrigerator that warned against putting a residential model in an RV. Figured that caveat had more to do with the install than the actual use. Refrigerators just sit in a house and are free to roll out, but must be firmly secured in an RV. I rebuilt the cabinet in the RV and anchored the new one so it will not wander. The residential model does much better in humid conditions and will not ice up. Installed a drip tube to carry any condensate down and away from the RV rather than having it accumulate in the plastic pan. It gets pretty sticky in south Texas. The cost was a convincing factor: $300 rather than $1300. I'd do it again in a heartbeat!
