Dometic RV refrigerator won’t stay lit. Easy fix for about $50

Our Dometic refrigerator on our Mallard camper would not stay lit would like, but was not sensing that it was lit so it would cut off and re-light over and again. Even after cleaning everything well I couldn’t get it to stay lit. I replace the circuitboard for a little more than $50, and it was a easy fix it lit and stay lit immediately.
