What an RV electrician does and why you need one

An RV electrician works on the electrical systems inside recreational vehicles — the 12-volt DC systems that power lights and appliances when you're off the grid, the 120-volt AC systems that run when you're plugged into shore power, and the converters and batteries that tie them together. Unlike a standard house electrician, an RV electrician understands how these systems work in a moving vehicle, where weight, vibration, and moisture create different failure patterns than a stationary home.

You need an RV electrician when you have problems that go beyond flipping a breaker: lights that dim when you run the microwave, outlets that stop working, a refrigerator that won't stay cold, a water heater that won't ignite, or a battery that won't hold a charge. Some of these problems are straightforward (a tripped breaker, a loose connection), but many require someone who knows RV wiring diagrams and can trace a fault through systems that are often cramped and hard to access.

Key Takeaways

  • RV electricians specialize in 12-volt DC and 120-volt AC systems specific to recreational vehicles, which are different from house electrical work.
  • You can find RV electricians through RV dealerships, independent shops that service RVs, roadside information programs, and online directories like the RV Industry Association.
  • Costs vary widely depending on the problem and your location, but expect to pay a service call fee plus hourly labor, typically ranging from $75 to $150 per hour for independent shops.
  • Before hiring, ask whether the electrician has experience with your specific RV type (motorhome, travel trailer, fifth wheel) and whether they can diagnose the problem before committing to repairs.
  • If you're on the road, roadside information programs like Good Sam or your RV manufacturer's roadside service can dispatch an electrician to your location.

Where to find an RV electrician near you

The easiest starting point is the RV dealership where you bought your vehicle or the nearest dealership of your brand. They have electricians on staff who know your model inside and out, and they can often fit you in quickly if you're a customer. The downside is that dealership labor rates are usually higher than independent shops — sometimes $100 to $150 per hour or more — and you may wait longer during busy seasons.

Independent RV service shops are usually cheaper and faster. Search online for "RV repair near me" or "RV service" plus your town name, and call three or four shops to ask about availability and pricing. Ask specifically whether they work on your type of RV (motorhomes, travel trailers, and fifth wheels have different layouts and electrical configurations). Many independent shops will give you a rough estimate over the phone if you describe the problem.

If you're traveling and break down on the road, call your roadside information program first. Good Sam, AAA, and most RV manufacturer roadside services will dispatch a mobile electrician to your location. These services cost money upfront (usually $50 to $200 per year for membership), but they cover the dispatch fee and often negotiate labor rates with partner shops. Your RV's warranty paperwork should list the roadside service number.

Online directories like the RV Industry Association (RVIA) and the National Association of RV Parks and Campgrounds (ARVC) maintain lists of certified service providers by region. These aren't comprehensive, but they're a good way to find shops that have met industry standards.

What to expect during a diagnostic visit

When you call an electrician, describe the problem as specifically as you can: "The bedroom lights flicker when the air conditioner runs" is more useful than "the electrical system is acting weird." Tell them whether the problem started suddenly or gradually, and whether it happens only in certain situations (plugged in vs. on battery, engine running vs. off, specific appliances running).

Most electricians will charge a service call fee to come look at the problem — typically $50 to $100 — and then charge hourly labor to diagnose it. Some shops will credit the diagnostic fee toward repairs if you hire them to fix it. Ask about this when you book. A good electrician will not commit to a repair price until they've actually traced the fault, because RV electrical problems often have multiple possible causes.

Bring your RV's manual if you have it, and write down any error codes or warning lights you've seen. If the problem is intermittent, try to describe exactly what you were doing when it happened. The more information you give the electrician upfront, the faster they can narrow down the cause.

Understanding RV electrical systems so you can ask the right questions

RVs have two separate electrical systems that work together. The 12-volt DC system runs on batteries and powers lights, fans, water pumps, and slide-outs. The 120-volt AC system runs when you're plugged into shore power (at a campground) or when a generator is running, and it powers the air conditioner, microwave, water heater, and large appliances. A converter changes 120-volt AC power down to 12-volt DC to charge the battery and run DC appliances when you're plugged in.

When something stops working, the electrician needs to figure out which system is at fault. If your lights work but your microwave doesn't, it's an AC problem. If your lights are dim but your microwave works fine, it's usually a DC problem (a weak battery or a charging issue). If nothing works, the problem might be at the shore power connection or the breaker panel.

When you talk to an electrician, listen for these terms: they should ask about your battery voltage, whether you're plugged in or on battery, and whether your engine is running. If they don't ask these questions, they may not be taking a systematic approach to the diagnosis.

Typical RV electrical problems and what they cost to fix

A tripped breaker or blown fuse is free to fix if you do it yourself (just flip the breaker back or replace the fuse). If an electrician does it, you'll pay the service call fee, usually $50 to $100. The real cost comes if the breaker keeps tripping, which means something is drawing too much power or there's a short circuit — that diagnosis and repair could run $200 to $500 depending on what's wrong.

A dead or weak battery usually means either the battery itself is failing (replacement $150 to $400) or the converter isn't charging it properly (diagnosis and repair $200 to $600). A battery that won't hold a charge overnight might just need to be replaced; a battery that drains while you're driving suggests a converter problem.

Appliance failures — a refrigerator that won't cool, a water heater that won't ignite, a microwave that won't power on — often have electrical causes. These typically run $150 to $400 in labor to diagnose and repair, plus the cost of parts if something needs to be replaced. Sometimes the problem is just a tripped breaker or a loose connection, which takes 15 minutes and costs only the service call fee.

Shore power connection problems (you're plugged in but nothing is working) usually mean a bad connection at the pedestal, a failed breaker in your RV's main panel, or a bad power cord. Diagnosis is $75 to $150; repair is usually $100 to $300 if it's a connection or breaker, or $200 to $500 if the power cord needs replacement.

Questions to ask before you hire

Ask whether the electrician has worked on your specific RV model or brand. A shop that specializes in Winnebagos may not be the best choice if you own a Forest River. Ask how long they've been in business and whether they're licensed and insured. In most states, RV electrical work doesn't require a state license the way house electrical work does, but a reputable shop will carry liability insurance and may have certifications from the RV Industry Association.

Ask what their diagnostic process is. A good electrician will test voltage at key points, check connections, and review your RV's wiring diagram before telling you what's wrong. If they want to start replacing parts without testing first, find someone else.

Ask whether they can give you a written estimate before they start work. Some shops will do this after the diagnostic; others charge for the diagnostic and then give you a repair estimate. Either way, you should know the cost before they start tearing into your electrical system.

Ask about warranty on their work. Most shops will may provide their labor for 30 to 90 days, meaning if the same problem comes back, they'll fix it for free. Parts usually come with the manufacturer's warranty, not the shop's warranty.

When to try a DIY fix versus calling a professional

If a breaker is tripped or a fuse is blown, flip the breaker or replace the fuse yourself — it costs nothing and takes two minutes. If it happens again when ready, stop and call an electrician; you have a short circuit or an overload, and fixing it yourself could be dangerous.

If an outlet isn't working but others are, check whether the outlet has a reset button (some RV outlets have built-in GFCI protection). Press the reset button and see if power comes back. If not, the outlet may need replacement, which is a $50 to $150 job for an electrician.

If your battery is dead and you're parked at a campground with shore power, plug in and let the converter charge the battery for a few hours. If the battery still won't hold a charge after that, it probably needs replacement.

Anything beyond these straightforward checks — tracing a fault, testing components, replacing converters or chargers, rewiring circuits — should go to a professional. RV electrical systems carry real shock and fire hazards, and a mistake can damage expensive appliances or create a safety problem that shows up weeks later.

Frequently Asked Questions

How much does it cost to hire an RV electrician?

Service call fees typically run $50 to $100, and hourly labor ranges from $75 to $150 per hour depending on whether you're at a dealership (higher) or an independent shop (lower). A straightforward fix like replacing a breaker might cost only the service call fee. A complex diagnosis and repair could run $500 to $1,500. Always ask for an estimate before work begins.

Can I use a regular house electrician for my RV?

Not for most RV work. House electricians are trained on 120-volt AC systems and don't understand 12-volt DC systems, converters, or the specific layouts of RV wiring. They could damage your RV or create a safety hazard. Stick with someone who specializes in RVs.

What should I do if my RV breaks down on the road?

Call your roadside information program first — Good Sam, AAA, or your RV manufacturer's roadside service. They'll dispatch a mobile electrician to your location and handle the payment. If you don't have roadside information, search online for "RV repair near me" and call local shops to ask if they can come to you or if you need to tow to their location.

How do I know if my battery needs replacement or if it's a charging problem?

If the battery is completely dead and won't take a charge after several hours plugged into shore power, it probably needs replacement. If the battery charges fine when plugged in but dies overnight when you're off-grid, the battery is failing. If the battery drains while you're driving, the converter isn't charging it properly. An electrician can test the battery and converter to tell you which is the problem.

Is RV electrical work covered by warranty?

If your RV is still under manufacturer warranty, electrical problems may be covered. Check your warranty paperwork or contact the manufacturer. Most warranties cover defects in materials and workmanship for one to three years. Wear-and-tear items like batteries are usually not covered. If you're out of warranty, you pay for all repairs.
