Traveling around New Zealand in a motorhome is an incredible experience. The freedom to explore stunning landscapes, from rugged coastlines to lush forests, is unbeatable. But let’s be honest - sometimes things don’t go exactly as planned with your RV. Whether it’s a minor hiccup or a more serious issue, knowing how to handle common problems can save you time, stress, and money.
In this post, we’ll walk through practical RV problem solutions that every motorhome renter or owner should know. We’ll cover everything from electrical glitches to plumbing troubles, and even some tips on staying safe and prepared on the road. Plus, I’ll share some insider advice to help you feel confident no matter where your New Zealand adventure takes you.
Common Electrical Issues and How to Fix Them
Electrical problems are among the most frequent annoyances in motorhomes. They can range from dead batteries to faulty lights or appliances not working. Here’s how to tackle these issues step-by-step:
Battery Problems: If your RV won’t start or the lights are dim, the battery might be drained. First, check the battery terminals for corrosion or loose connections. Clean and tighten them if needed. If the battery is old (more than 3-5 years), it might be time for a replacement. Carry a portable jump starter or jumper cables just in case.
Blown Fuses: A blown fuse can cause certain electrical components to stop working. Locate your fuse box (usually near the driver’s seat or inside a cabinet) and inspect the fuses. Replace any blown ones with the correct rating. Keep spare fuses handy.
Appliance Issues: If your fridge, microwave, or heater isn’t working, check if they’re properly plugged in and the circuit breaker hasn’t tripped. Sometimes, resetting the breaker or unplugging and plugging back in can fix the problem.
Solar Panel Troubles: Many motorhomes have solar panels to keep batteries charged. If you notice a drop in power, clean the panels and check the wiring for damage. Make sure the charge controller is functioning correctly.
Pro tip: Always carry a multimeter to test electrical circuits. It’s a small investment that can save you hours of guessing.

Plumbing Problems and Quick Fixes
Water systems in motorhomes are convenient but can be tricky. Leaks, clogged drains, or water pump failures are common. Here’s how to keep your plumbing in check:
Leaky Faucets or Pipes: If you spot water dripping, tighten the fittings or replace worn washers. For small leaks in pipes, waterproof tape or pipe sealant can be a temporary fix until you get professional help.
Clogged Drains: Hair, soap, and food particles can block sinks and showers. Use a plunger or a drain snake to clear the blockage. Avoid harsh chemicals as they can damage your RV’s plumbing.
Water Pump Not Working: If your taps have no water pressure, check if the pump is switched on and the fuse is intact. Sometimes, air trapped in the system causes the pump to lose prime. Run the taps for a few minutes to clear air bubbles.
Empty or Frozen Tanks: Always monitor your fresh, grey, and black water tanks. Empty them regularly at designated dump stations. In colder months, use RV antifreeze to prevent pipes from freezing.
Remember: Carry a basic plumbing repair kit with wrenches, sealant, and spare washers. It’s a lifesaver when you’re off the beaten track.

Heating and Cooling Tips for Comfort on the Road
New Zealand’s weather can be unpredictable, so keeping your motorhome comfortable is key. Here’s how to troubleshoot heating and cooling problems:
Heater Won’t Start: Check the fuel supply if you have a gas heater. Make sure the thermostat is set correctly and the pilot light is on. If it’s electric, inspect the fuse and wiring.
Air Conditioner Not Cooling: Clean or replace the air filter regularly. Check the power supply and reset the breaker if needed. If the unit still doesn’t cool, it might need professional servicing.
Ventilation Issues: Proper airflow prevents condensation and mould. Use roof vents and windows strategically. If your RV has a fan, make sure it’s working and clean.
Portable Heaters and Fans: Carrying a small portable heater or fan can be handy for extra comfort, especially in remote areas.
Tip: Regular maintenance of your heating and cooling systems before your trip can prevent many headaches.
Safety Checks and Preventative Maintenance
Staying safe on the road means being proactive. Here are some essential checks and maintenance tips:
Tyre Inspection: Check tyre pressure and tread depth before every trip. Look for cracks or bulges. Carry a tyre repair kit and a portable air compressor.
Brake System: Listen for unusual noises and test brakes regularly. If you notice any issues, get them checked immediately.
Gas and Propane Safety: Inspect gas lines and connections for leaks. Use soapy water to detect bubbles. Always turn off gas appliances when driving or sleeping.
Fire Extinguisher and Smoke Alarms: Make sure your fire extinguisher is charged and accessible. Test smoke and carbon monoxide detectors regularly.
Emergency Kit: Pack a first aid kit, flashlight, extra batteries, and basic tools. Having a roadside assistance plan is also a smart move.
Pro tip: Keep a checklist of these safety items and review it before every trip.
