RV Converter Repair

Can you replace my converter without draining my battery?

Yes. The first thing we do is disconnect the negative battery terminal, which isolates the battery bank from the circuit without draining it.

Shore power stays connected to the RV's main panel throughout the swap, so hardwired systems that draw directly from shore - like your air conditioner on a dedicated breaker - are unaffected. During the work window, your fridge, slides, and 12V lights will be off because they run through the converter circuit, but the battery itself isn't being drawn down.

Once the new converter is seated, wired, and fuse connections confirmed, we reconnect the negative terminal and test output voltage at the battery terminals to verify the unit is charging correctly before we close up. If your battery was already low coming in, we'll let you know - a depleted battery can take 30-60 minutes to show a stable reading, and we won't leave until the numbers look right.

How much does a converter replacement cost for my Jayco fifth-wheel?

Jaycos typically use a 55-60 amp converter, and replacement runs $500-$520 installed whether we put in a Progressive Dynamics or WFCO unit. That flat rate covers the old unit pull, wiring transfer, new converter install, and a load test to confirm the output is hitting 13.4-13.8V at the battery terminals before we leave.

The variance between those two brands comes down to parts availability the day of your job - both perform comparably in a residential-style converter application. If we open the converter bay and find corroded buss bars or melted wiring from a previous overload, that's a separate line item we call you about before touching anything. We quote flat-rate by phone with your year and model, so the number on the invoice matches what you heard upfront.

Is a lithium-compatible converter different from a regular one?

Yes - lithium batteries charge at a different voltage profile than lead-acid, and using a converter designed for lead-acid can shorten the life of your lithium bank or trip the battery's built-in protection circuit repeatedly. A lithium-compatible converter like the WFCO 80-amp unit ramps the charge rate down smoothly as the battery approaches full rather than holding a float voltage that lithium cells don't want.

On a job, we verify the converter's output profile with a meter before we call the install done - it's not enough to just bolt in the new unit. If you're upgrading to Battle Born or Victron lithium, we'd recommend stepping up to the 80-amp WFCO even if your current setup runs a 55-amp, because lithium charges faster and you want the headroom to take advantage of that without pushing the converter to its limit on every cycle.

Can I fix my converter myself, or do I need a pro?

Resetting a tripped breaker on the converter is a reasonable DIY step - check the breaker panel, reset it, and see if output voltage comes back on shore power. Beyond that, the work moves into territory where mistakes are expensive and occasionally dangerous.

Inside a converter you're dealing with high-voltage AC input, heat-producing rectifier components, and circuit boards where a solder bridge in the wrong place can cause a thermal runaway or take out downstream 12V devices throughout the rig. We've seen a $200 board repair turn into a $1,200 replacement because a previous attempt pushed current through the wrong path. If your converter won't power on, outputs zero or erratic DC voltage, or runs hot and shuts off under light load, those are diagnostic jobs - bring in a tech who can trace the fault before touching anything.

How fast can you respond if my converter dies while I'm camping?

In our our covered metros core service areas, we target a 2-4 hour response for emergency calls - a dead converter means no battery charging, no 12V lighting, and refrigerators that switch to propane-only mode, so we treat it as urgent. When we arrive, we run a quick voltage test at the battery and converter output terminals to confirm the converter is the failure point before pulling anything apart, then we either repair or swap the unit on-site depending on what we find. Outside our core areas, we dispatch through our nationwide certified-tech partner network, and availability varies by region - call us and we'll give you a real ETA based on who's actually closest to your location, not a generic estimate.

Will upgrading my converter let me boondock longer without a generator?

A converter only works when you're plugged into shore power, so upgrading it does nothing for off-grid time. What actually extends a boondocking stay is adding battery capacity - either more AGM lead-acid banks or a switch to lithium, which gives you usable capacity closer to 100% versus the 50% you get from lead-acid before you risk damage.

Pair that with an inverter sized to your 120V loads (microwave, CPAP, outlets) and you have a real off-grid system. Where a converter upgrade does fit into that picture is if your current unit is undersized to properly recharge a larger battery bank when you do hook up to shore power - a weak converter will take twice as long to recover your batteries after a night of heavy use. We can assess all three pieces together and quote a bundled install so you're not paying separate trip charges for each component.

Do I really need to replace the whole converter, or just the breaker?

The breaker is always the first thing we check, because it fails more often than the converter itself and costs a fraction of the price to swap. If the breaker trips under load but resets cleanly and the converter puts out 13.4-13.8V on shore power afterward, a new breaker at $120 closes the job.

If the breaker looks fine or a new one still trips immediately, that points to an internal fault in the converter - a failed transformer, bad capacitor, or shorted rectifier diode - and at that point replacement makes more sense than chasing individual components. We carry common converter units on the truck, so if the diagnosis points to a full swap we can usually complete it the same visit. You only get quoted for what the diagnosis actually finds.

What happens if lightning strikes near my RV - is my converter covered?

Lightning damage voids manufacturer warranties almost universally - it falls under "act of God" exclusions that no converter brand covers, regardless of how the unit was installed or how new it is. Your best path is your RV insurance policy, which typically covers electrical damage from lightning strikes under comprehensive coverage.

We can come out, diagnose which components took the hit, and write a detailed repair estimate your adjuster can work from. Lightning rarely stops at the converter - the same surge often takes out the inverter, charge controller, and any 12V circuit boards downstream, so the inspection covers the full electrical system, not just the converter itself.

A converter replacement runs $500-$1,200 depending on amp capacity and whether the distribution panel needs work alongside it. File the claim first, then call us to schedule the diagnostic.
