"Li oP" is one of the most important Norcold codes. It means the high temperature limit switch has detected overheating at the cooling unit's boiler, which is usually caused by a failing cooling unit. Please don't bypass the switch or keep resetting it. It's there to prevent a fire. Read our post on Norcold fault codes Li oP for what to do next.
