Contrary to what the rest of the internet may tell you, RV converters are rarely fixable. In fact, some manufacturers design their converters specifically so they are not serviceable in the field (looking at you, WFCO). They either work, or they don’t. If your converter is dead or dying, you will need to unceremoniously divorce it for a newer, younger, better, version. But before you spend $200-$300 on a new converter, you should confirm your diagnosis.

Why Do RV Converters Die?

RV converters convert 120-volt alternating current electricity into 12-volt direct current electricity. DC electricity is used to power your lights, water pump, TV, furnace, and other light-duty loads.

This conversion process is never 100% efficient; some of the energy is dissipated as heat, and heat kills electrical components. Over time, the components degrade. There are other culprits as well: condensation, mice, beetles, dust, and dander. RV converters can die for multiple reasons, but eventually, nature will reclaim her own.
