On the NX/ NXA models, an "H" on the display usually points to a problem with the AC heating element or the AC heater circuit. Check the AC heater resistance and the AC fuse on the power board. Our post on Norcold fault codes AC, HE, H walks through exactly what to check, and the full list is on our Norcold error codes page.
