DIY RV Repairs: What You Can Fix Yourself vs. When to Call a Pro

Owning an RV means adventure, freedom—and the occasional unexpected repair. While some issues are simple enough to fix on your own, others are better left to the professionals. Knowing the difference can save you time, money, and stress on the road. In this post, we’ll break down common RV repairs you can confidently tackle yourself and when it’s smarter (and safer) to call in a pro.

✅ DIY RV Repairs You Can Handle Yourself

1. Replacing Fuses and Light Bulbs
If an interior light goes out or a system stops working, a blown fuse may be the culprit. Replacing fuses and bulbs is a quick, easy task most RVers can handle with minimal tools.

2. Sealing Small Roof or Window Leaks
Caught early, minor leaks can often be sealed with RV-specific sealants like Dicor or Eternabond tape. Regular inspections can help you spot trouble before it becomes a major repair.

3. Basic Plumbing Fixes
Simple clogs or leaks under the sink can usually be fixed with basic tools and parts. Most modern RV's use PEX tubing which requires PEX specific clamps and clamp tool. Investing in a PEX clamp tool is an excellent investment! Make sure to turn off your water supply and relieve pressure before getting started.

4. Battery Maintenance
Cleaning terminals, checking fluid levels (for lead-acid batteries), and ensuring secure connections are all routine tasks that help extend battery life.

5. Air Conditioner Filter Cleaning
Your A/C system works hard—especially in warm climates like Florida. Cleaning the filters regularly helps maintain airflow and efficiency.

🔧 When to Call a Pro

1. Electrical System Diagnostics
If you’re experiencing power issues beyond a blown fuse or tripped breaker, it’s best to call a professional. Diagnosing and repairing RV electrical systems—especially the AC side—can be dangerous without the right experience and tools.

2. Roof Reseals or Structural Damage
A small leak may be DIY-friendly, but large areas of roof damage or resealing an entire roof is a job for someone with experience to ensure proper sealing and no future issues.

3. Water Heater or Furnace Problems
These systems involve propane, electricity, and plumbing—often all at once. If your water heater isn’t working properly, leave it to an experienced RV technician to troubleshoot and repair safely.

4. Slide-Out Malfunctions
Slide-out systems involve motors, gears, and electronics. Trying to fix a jammed slide-out without proper knowledge can cause more damage and costly repairs.

Final Thoughts
