RV Tips - Troubleshooting on the Road

This document provides a guide to common issues encountered while traveling in a Recreational Vehicle (RV) and suggested troubleshooting steps. Being prepared for minor setbacks can help ensure a smooth and enjoyable trip.

Electrical Issues

Electrical problems can range from simple blown fuses to more complex converter/inverter issues.

No Power (Shore Power)

If plugged into a campsite pedestal and you have no power:

1. Check the Pedestal Breaker: Turn the breaker off, wait a few seconds, and then turn it back on. Sometimes breakers trip silently.
2. Check Your RV Main Breaker: Locate your main breaker panel (usually near the converter/inverter) and check if the main breaker is tripped.
3. Check the Shore Power Cord: Look for signs of damage or burn marks on the plug end or along the cord.

12V DC System Failures

The 12V system powers lights, water pumps, and fans.

Issue	Potential Cause	Troubleshooting Step
Lights dim or flicker	Low battery voltage	Check battery monitor; ensure converter is working to charge the batteries.
Water pump not working	Blown 12V fuse	Locate the fuse panel (often near the converter) and replace the specific fuse for the pump.
Furnace/Thermostat dead	Faulty circuit board or fuse	Check furnace fuse and try resetting the main 12V disconnect.

Plumbing and Water Issues

Water system troubles are among the most common, especially concerning pressure and leaks.

Low or No Water Pressure

If your shower or sink has poor pressure:

1. Check Water Source: If connected to city water, ensure the spigot is fully open.
2. Inspect Water Filter: A clogged inline water filter (either external or internal to the RV) can severely restrict flow. Replace or bypass the filter.
3. Check Pressure Regulator: If you use an external regulator, it may be faulty or set too low. Ensure you have a working RV pressure regulator.

Leaks

Water leaks need immediate attention to prevent interior damage.

• Under the Sink: Tighten fittings by hand. If a plastic P-trap is leaking, it may need re-seating or replacement.
• Outside Hoses: If the leak is from your city water connection, ensure you have a fresh rubber washer in the hose coupling.
• Identify the Source: If the leak is persistent and its source is not visible, consider a temporary stop at an RV service center.

Engine and Driving Concerns (Motorhomes)

For RVs that are self-powered (Class A, B, or C motorhomes).

Engine Overheating

If the temperature gauge spikes:

1. Pull Over Safely: Turn on the hazard lights and pull over immediately.
2. Turn on Heater: Running the cabin heater on full blast can sometimes draw heat away from the engine as a temporary measure.
3. Check Coolant: DO NOT open the radiator cap while the engine is hot. Wait for the engine to cool, and then check the coolant level.

Brake Squeal or Grinding

Brake issues should be addressed quickly.

• Squealing: Often indicates worn pads or rotors, or sometimes rust after rain. Schedule an inspection at an auto shop.
• Grinding: Requires immediate attention. Pull over and arrange for towing or roadside assistance before continuing.

Slide-Out Malfunctions

Slide-outs add significant living space but can occasionally get stuck.

Slide-Out Won't Extend or Retract

1. Check Power and Level: Ensure your RV batteries are fully charged (slide-outs require significant power) and that the RV is as level as possible.
2. Check for Obstructions: Look for loose items, debris, or mats that might be blocking the mechanism.
3. Check Fuses: Slide-outs often have large inline fuses or circuit breakers near the battery or controller.
4. Refer to Manual: Most slide-outs have a manual override procedure. Locate the manual override access points and the specific instructions in your RV manual.
