RV Converter Repair service

Your RV converter takes 120V AC shore power and converts it to 12V DC to charge batteries and power your 12V systems. A failing converter means dead batteries, dim lights, and non-functional 12V accessories. Sun Coast RV Service diagnoses converter issues quickly with precision voltage testing.

Symptoms of a Bad RV Converter

  • Batteries not charging on shore power
  • Dim or flickering 12V lights when plugged in
  • Converter fan running constantly or not at all
  • Burning smell from the converter area
  • 12V voltage reading below 13V at the battery when plugged in

Repair vs. Upgrade

Older single-stage converters can overcharge and boil batteries. We often recommend upgrading to Progressive Dynamics or WFCO multi-stage converters that provide proper bulk, absorption, and float charging. This extends battery life significantly, especially important for Florida's heat which already stresses batteries.
