We had the same problem after a heavy, blowing rain. Refrigerator shut itself off, code on display indicated high temp cutoff and that it was not a problem we could fix, that we needed to call for service. We called a serviceman and by the time he got there, it had reset itself. Since he was there, we asked him to check things out. In addition to the rain, the panel at the top of the compartment had dropped down and was blocking the vent, keeping the heat in, and allowing it to build up (and trip the hi temp control). He was able to push it back up into place and secure it with a screw so we wouldn't have that problem again. He also found that the bottom of the compartment was wet from more than the rain.The overflow hose for the evaporation pan had been left inside instead of draining outside. He re-routed it so we wouldn't have that problem (would have rotted out the bottom of the compartment over time). He told us they (Norcold and other mftr's) use the same size evaporation pan for both sizes of refrigerator and it simply isn't big enough for the larger ones (we have a 12 cu ft) so it's imperative that the hose drain outside. Bottom line,it wasn't a refrigerator problem, it was a RWinstallation problem (quality control again). We had to pay him because it wasn't a refrigerator warranty problem. We've sent the bil to RW to be reimbursed.
