On a side note!! My 07 Meridian had the Norcold safty switch recall box thing. This may be way yours was disconnected. Mine kept tripping and turning the frig off. Thats what its is to do when there is a heat build up problem. In reading different posts on the subject found a way to reset it with a magnet.
After fighting with the switch way to often it came that it would not reset. To make a long story short ended up being frig. was shot. Time to think of what to do.
We decided to go with a totally 120v replacement cooling unit from JC Refgeration. Did work ourselfs could not be happier.
