Owning an RV is all about adventure, freedom, and making memories on the open road. But let’s be honest—no RV is completely maintenance-free. Whether you’re taking your toy hauler out to the dunes or heading to Rocky Point for the weekend, you’ll eventually run into common RV problems. The good news? Many of these issues have simple fixes that you can handle yourself.
At Rowley White RV, we want you to spend more time enjoying the journey and less time worrying about repairs. That’s why we’ve put together this troubleshooting guide to help you tackle the most common RV problems and keep your rig in top shape. Let’s dive in!
Common RV Problems Every Owner Should Know
RVs, like any other vehicles, experience wear and tear over time. However, since we don’t sell motorized RVs at Rowley White RV, this guide will focus on issues specific to toy haulers and travel trailers—like the ones we proudly offer from Genesis Supreme and Forest River. Here are some of the most common problems RV owners face:
- Leaks and water damage – Often caused by worn-out seals, cracked caulking, or roof issues.
- Electrical failures and battery problems – Dead batteries, faulty outlets, or flickering lights can ruin a trip.
- Furnace and AC malfunctions – A broken HVAC system can turn your RV into an oven in the summer or a freezer in the winter.
Now, let’s explore how to troubleshoot and fix these common RV repair issues.
How to Troubleshoot and Fix Minor Issues
Leaks and Water Damage
Water damage is one of the biggest threats to an RV. Once moisture sneaks in, it can lead to rot, mold, and structural damage. Here’s how to prevent and fix leaks:
Signs of Water Damage:
- Soft spots in the floor or walls
- Musty odors
- Stains or discoloration on the ceiling
- Warped wood or bubbling wallpaper
How to Fix It:
- Inspect Seals and Caulking – Check around windows, doors, vents, and roof seams. If you see cracks or peeling, clean the area and reapply an RV-safe sealant like Dicor or Sikaflex.
- Patch Roof Leaks – If you find a tear or hole in your roof membrane, patch it with RV roof repair tape or liquid rubber sealant.
- Check Plumbing Connections – If leaks are coming from under the sink or behind the shower, tighten fittings or replace worn-out seals.
- Dry Out Affected Areas – If you catch water damage early, use fans and dehumidifiers to dry out the area before mold sets in.
Electrical Failures and Battery Issues
Electrical problems can be frustrating, whether it’s flickering lights or dead outlets. Most issues stem from battery failures, blown fuses, or loose connections.
Signs of Electrical Issues:
- RV lights dim or flicker
- Battery drains quickly or won’t hold a charge
- Outlets stop working
- Furnace or water pump won’t turn on
How to Fix It:
- Check the Battery – If your battery won’t hold a charge, test it with a multimeter. If it’s below 12 volts, recharge or replace it.
- Inspect Fuses and Breakers – If something stops working, check your fuse panel. A blown fuse is easy to spot—just replace it with one of the same amperage.
- Tighten Connections – Loose wires can cause flickering lights. Check the wiring in your converter box, outlets, and battery terminals.
- Test the Shore Power Connection – If you’re plugged into a power source but still having issues, test the outlet with a voltage tester to rule out campground power problems.
Furnace and AC Problems
Nothing’s worse than losing heat in the middle of a cold night or having your AC fail in the summer heat. Luckily, most RV HVAC issues have simple fixes.
Signs of HVAC Problems:
- Furnace or AC won’t turn on
- Airflow is weak or inconsistent
- Strange noises or burning smells
- AC freezes up or leaks water
How to Fix It:
- Check the Thermostat – Make sure it’s set to the right mode and temperature. If it’s battery-powered, replace the batteries.
- Inspect Air Filters – A clogged filter can restrict airflow. Clean or replace it as needed.
- Check Propane Supply – If your furnace isn’t working, make sure your propane tank is full and the regulator is functioning.
- Clear AC Drain Lines – If your AC is leaking inside, the condensation drain line might be clogged. Use a pipe cleaner or compressed air to remove debris.
- Listen for Strange Noises – Loud banging or rattling could mean loose components. Tighten screws and panels if needed.
When to Call a Professional for RV Repair
While many common RV issues are DIY-friendly, some repairs require expert attention. Here are a few situations where it’s best to call a professional:
- Structural Damage – If water damage has compromised the frame or subfloor, you’ll need professional repair.
- Major Electrical Failures – If your breaker keeps tripping or your converter isn’t charging the battery, an electrician should diagnose the issue.
- Appliance Repair – If your fridge, furnace, or water heater isn’t working despite troubleshooting, a certified RV technician can pinpoint the problem.
- Brake and Axle Issues – If your RV brakes feel weak or you notice uneven tire wear, get your suspension and axles checked out.
