They may be separate problems. "DC LO" means the fridge is seeing low 12V voltage, so check your battery, converter and 12V connections at the fridge first. Low voltage can cause all kinds of strange behavior. "LI oP" means the high temp limit on the boiler is open. If LI oP keeps showing up after the voltage is fixed, check the limit switch. The 637360/50808 high temp switch fits the 2118 but is a special order item with a 2–3 week lead time. If the fridge also isn't cooling, the cooling unit may be the underlying cause.
