RV converter repair and replacement in Miami. Converter replacement costs $180-$320 installed. A failed converter leaves your 12V system without a charge source from shore power. RV Repair Miami replaces WFCO and Progressive Dynamics converters at your Miami-Dade location. Call (305) 912-8800.
The converter in your RV takes 120V AC shore power or generator power and converts it to 12V DC to power your coach lighting, fans, slides, leveling jacks, and slides - while simultaneously charging your house batteries. When the converter fails, your 12V system runs entirely on battery until the batteries drain, and the batteries receive no charge while plugged in.
Symptoms include: 12V items (lights, fans, water pump) that work briefly then gradually dim and stop; batteries that drain despite being plugged in at a campsite; and battery charger indicator showing no charge even with shore power connected. WFCO and Progressive Dynamics are the two most common converter brands in Miami RVs, and we stock replacement units for the most common models (30A, 45A, 55A) on every service van.
Diagnosing Converter Failure in Miami

Converter failure is confirmed with a meter - correct output is typically 13.6V to 14.4V DC at the output terminals when shore power is applied. Output below 12.5V means the converter is not charging; output above 15V means the converter is overcharging and may damage batteries. No output at all with shore power confirmed at the input means the converter has fully failed.
Before confirming converter failure, we also check the fuse in the converter's AC input circuit - a blown fuse on the input side mimics converter failure completely. This takes 5 minutes and saves a $320 replacement on a fuse that costs $2. We perform the full diagnostic sequence before recommending any parts.
Replacement Options and Miami Considerations

For direct replacement, we match the amperage rating of the original converter to ensure the new unit can handle the 12V load in your specific RV. A 30A converter is appropriate for most travel trailers; larger Class A motorhomes often need 45A or 55A.
We also recommend progressive Dynamics's 4-stage charging profile converters (PD9200 series) over basic 3-stage units for Miami RVs - the 4-stage profile includes a temperature-compensated absorption stage that adjusts charging voltage based on battery temperature, which is particularly valuable in Miami's heat where standard absorption voltage targets can overcharge warm batteries. Replacement and testing takes 1.5-2 hours at your Miami-Dade location.

Common RV Converter Repair Issues in Miami
Electrical problems in Miami often show up at the start of camping season after a rig has sat in storage. Battery sulfation from sitting without a maintenance charger is the most common finding - a battery that shows 12 volts on a meter may fail completely under load after months of storage in Miami-Dade County's heat.
Converter failures from overheating in poorly ventilated compartments are the second most common call. We also see frequent 12-volt wiring issues from rodent damage in rigs stored at outdoor lots.
Miami and Miami-Dade County RV owners face the same Florida climate challenges as the rest of Central Florida, with year-round heat, high humidity, and a June through September storm season that creates specific wear patterns on RV systems. Rigs stored outdoors in Miami-Dade County between trips experience UV degradation on roof seals and awnings, battery drain from inactivity, and generator fuel varnish from ethanol-blend gasoline left standing in the tank. Those are the conditions that drive most of the service calls we handle in Miami.
How Our RV Converter Repair Service Works in Miami
Electrical diagnosis follows the power path from source to load - shore power connection, main breaker, converter output, battery bank, then individual circuits. Marcus uses a clamp meter and battery load tester for objective diagnosis rather than visual inspection alone.
That approach saves you money on parts that do not need replacing. Most electrical repairs - fuse and breaker work, converter replacement, battery replacement, shore power issues - are completed same-visit.
Mobile service means no towing costs and no shop wait. We come to campgrounds including Larry and Penny Thompson Memorial Park, Everglades National Park (Flamingo and Long Pine Key campgrounds), Biscayne National Park, Mack's Fish Camp in Homestead, Homestead Bayfront Park, as well as storage facilities and private residences throughout Miami-Dade County. Call (305) 912-8800 or use the contact form to schedule service.
We confirm appointments within 2 hours during business hours (Monday through Saturday, 7am to 7pm). Emergency response is available 24 hours a day for safety-related situations.
What to Have Ready When You Call
Note which circuits or outlets are affected and whether the problem occurs on shore power, generator power, or both. If you smell burning or see scorch marks, do not use that circuit and mention it right away - that changes the priority of the visit.
If you have a battery issue, tell Marcus the battery age and type (lead-acid or lithium). For shore power issues, tell Marcus what the campground's electrical pedestal looks like - 30-amp or 50-amp.

Q & A
RV Converter Repair in Miami - Questions and Answers
How do I know if my RV converter has failed?
Check the DC output voltage at the converter terminals with a multimeter while shore power is connected. Correct charging output is 13.6-14.4V DC.
Below 12.5V means no charging; no output at all means converter failure. Also check the converter's AC input fuse - a blown input fuse mimics complete converter failure.
How much does RV converter replacement cost in Miami?
30A converter: $180-280. 45A: $220-320. 55A: $260-380. All installed at your Miami-Dade location, flat-rate before dispatch.
What is the difference between a converter and an inverter?
Converter: shore power (120V AC) → 12V DC to power coach systems and charge batteries. Inverter: battery (12V DC) → 120V AC to power standard AC appliances without shore power or generator. Many newer RVs have combination inverter-charger units that do both.
My batteries drain even though I am plugged in at a campsite. Is that the converter?
It is a likely cause. Plug a lamp into a 120V outlet inside the RV to confirm shore power is reaching the interior - if the lamp works but the batteries are still draining, the converter is probably not charging. Call us for same-day diagnosis.
How long does converter replacement take?
1.5-2 hours at your Miami-Dade location. We test output under load before completing the service.
Do you perform rv converter repair at campgrounds in Miami-Dade?
Yes. We service Larry and Penny Thompson Memorial Park, Miami Everglades Resort, Homestead Campground, and all RV parks, storage facilities, and driveways across Miami-Dade. Call (305) 912-8800 for same-day service.
What RV brands do you work on?
All major brands - Tiffin, Newmar, Winnebago, Jayco, Forest River, Grand Design, Keystone, Coachmen, Thor, Airstream, Lance, and all others. We are brand-agnostic across all service types.
How does flat-rate pricing work?
We quote a firm price by phone covering parts, labor, and travel before we dispatch. That number is your invoice total - no surprise add-ons.
If we find something extra on-site, we stop and call you before proceeding. Call (305) 912-8800.
How fast can you get to me in Miami-Dade?
Same-day for most calls before noon across Miami-Dade. Emergency response is 2-4 hours.
Homestead and the Keys gateway area are typically next-day. Call (305) 912-8800 for a firm arrival window.
