Refrigerator Problem

RME46_

Our 2010 T@B has a 12 Norcold Model DC 0740B compressor type refrig. All electric model - no propane involved.  On a camping trip a few days ago, the refrigerator was working great and cooling as it should, at all settings.  We'd shut it down for the night and next morning, upon turning the fridge on, the little green light came on, as always. One could hear a faint high pitched sound.  Upon turning up the knob that kicks the compressor on, the compressor did not come on regardless of how far one rotated the knob.  Battery seems to be working ok and, get this same issue occurs even when on shore power.  Did not get a manual with the refrigerator.  Might there be a fuse somewhere that I don't know about?
