after turning on the frig for two days b=prior to leaving, when I got to my first stop, I had a warm frig and an error. I opened the back of the frig (door on outside of the rig) and while looking for a fuse, I found a loose wire. when I reconnected it, the frig came back on and has been fine ever since. goes with my saying.....the simplest are the bestest. check the simple things....maybe you have a bad ground somewhere.
