For many Southern California adventurers, RVs are more than just vehicles—they’re mobile homes, vacation dreams, and adventure companions. But while RVs offer freedom and comfort, they also come with risks, including the potential for fire. According to the National Fire Protection Association (NFPA), RV fires cause millions in damages annually, and many of these incidents could have been prevented with proper maintenance and awareness.
At McBride’s RV in Chino, CA, we believe in helping RV owners not only repair and maintain their motorhomes but also understand how to keep them safe. In this guide, we break down the most common causes of RV fires and provide expert tips on how to prevent them—based on decades of RV repair experience and a deep commitment to your safety.
1. Electrical System Failures

Faulty wiring, overloaded circuits, or damaged appliances are among the leading causes of RV fires. Older RVs, in particular, may have outdated wiring not suited for today’s energy demands. To prevent fires from electrical failures, it’s important to schedule routine inspections of your RV’s electrical system by certified professionals. Be sure to replace or repair frayed wires and faulty appliances, avoid overloading outlets, and use surge protectors to manage power fluctuations. McBride’s RV offers expert diagnostics and repairs to help ensure your rig’s electrical system is safe and reliable.
2. Propane System Leaks
Propane is essential for cooking, heating, and refrigeration in many RVs, but its flammable nature makes leaks extremely dangerous. These leaks often occur due to cracked hoses, malfunctioning regulators, or unsealed connections. Preventing propane-related fires starts with annual inspections of the propane system. Use a propane gas alarm for added safety and check connections regularly using a simple soapy water test—bubbles will indicate a leak. Always turn off propane before refueling or while the RV is in motion. At McBride’s RV, we thoroughly inspect propane systems to detect leaks and ensure proper operation.
3. Overheating Appliances (Refrigerators, Heaters, etc.)
RV refrigerators, heaters, and water heaters can become fire hazards if they’re not properly maintained. Poor ventilation, accumulated dust, or incorrect installation may cause these appliances to overheat. Preventative maintenance includes cleaning burner tubes and ventilation areas regularly and ensuring air can circulate freely around all appliances. Don’t use appliances while driving unless they are designed for that purpose. At McBride’s RV, we’re factory-certified to service major RV appliance brands like Dometic, Norcold, and Atwood, ensuring safe and efficient operation.
4. Engine and Transmission Issues
The engine compartment can be another fire-prone area due to oil leaks, overheating, or malfunctioning fuel lines. To mitigate this risk, follow the manufacturer’s service schedule for engine and transmission maintenance. Make it a habit to inspect for leaks during every oil change and schedule a full chassis inspection before long trips. McBride’s RV is certified to service Workhorse, Spartan, Ford, and Freightliner chassis, offering complete minor and major services to keep your rig running cool and safe.
5. Cooking Accidents
Cooking in a confined RV kitchen increases the risk of fire. Leaving food unattended, allowing grease to build up, or keeping flammable items near burners can easily lead to disaster. Always stay in the kitchen while cooking and be mindful of your surroundings. Avoid wearing loose-fitting clothes near open flames, and regularly clean your stovetop and surrounding surfaces. Equip your RV with a fire extinguisher rated for kitchen use and ensure it’s within reach. At McBride’s RV, we can help install kitchen safety features such as gas shut-off valves, fire blankets, and proper ventilation systems.
6. Battery Malfunctions
Overcharged or poorly maintained RV batteries can overheat or even explode, especially when housed in unventilated compartments. Corroded terminals and damaged cables also contribute to fire risk. To prevent battery-related fires, have your batteries tested before and after each trip. Keep terminals clean and secure, make sure there is proper ventilation, and avoid overcharging by using an appropriate charging system. At McBride’s RV, we offer complete battery service including performance testing, charging system checks, and battery replacements with trusted brands like Interstate and Lifeline.
7. Arcing from Inverters or Chargers
Inverter and charger systems can produce electrical arcs or overheat when improperly installed or maintained. This is especially risky in DIY setups without professional oversight. To minimize this danger, have your inverter or charger installed by trained professionals, regularly check for signs of overheating or wear, and make sure all wiring is properly insulated and secured. McBride’s RV technicians are certified to work on complex electrical systems, including inverter/charger installations, ensuring both safety and compliance with manufacturer standards.
8. External Sources: Wildfires, Campfires & Other Vehicles
Although less common, RV fires can also start from external sources such as nearby wildfires, campfires, or even adjacent vehicles with mechanical issues. When setting up camp, avoid parking your RV near tall grass, brush, or active fire pits. Always keep a fire extinguisher accessible on the exterior of your rig and practice caution when choosing campgrounds or boondocking sites. Keeping a current fire insurance policy and having it accessible in your RV is also a smart safety measure. If your RV is damaged by external fire sources, McBride’s RV offers full collision repair services and works directly with insurance companies to streamline claims.
Fire Prevention Equipment Every RVer Should Carry
Every RV owner should be prepared with essential fire safety equipment. At minimum, carry a multi-purpose (ABC-rated) fire extinguisher and check its expiration date regularly. Install and maintain working smoke and propane detectors inside the coach, and test them monthly to ensure functionality. A fire blanket can be useful in the kitchen or engine compartment. Lastly, have an emergency exit plan and practice it with your fellow travelers so everyone knows how to evacuate safely in an emergency.
