RV troubleshooting guides

Step-by-step fixes for RV and camper problems, sorted by system. Pick a system or search for the problem.

Fix guides (30)

System guides (how each part works, what fails, specs and FAQs)

Short answer

Pick the system that is acting up, then the symptom. Every guide starts with the cheapest checks, like battery voltage, breakers, fuses and the propane valve, before parts. If a display shows a code, look it up first, and stop and call a tech if you smell propane or the fix involves gas valves, refrigerant or a control board.

Common questions

Where should I start troubleshooting an RV?

Start with the part that stopped working and the power or fuel it needs. Check the house battery, breakers, fuses and the propane valve before you look at any part. If several things stopped at once, the cause is usually something they share, like a low battery or a tripped main breaker.

What are the most common RV problems?

No RV or appliance maker publishes a ranked list. The problems owners search for most are a furnace that will not light, a fridge that will not cool, a battery that will not charge on shore power, a water heater that works on gas but not electric, a water pump that runs without water, and a slide-out that will not move. Each one has a guide above.

What tools do I need to troubleshoot an RV?

A digital multimeter covers most electrical checks: battery voltage, fuses and outlets. Add a flashlight, a set of nut drivers and screwdrivers, and spare fuses. Gas pressure tests need a manometer, which is usually a job for a tech.

How often are these guides updated?

We update a guide when a maker changes a part or manual, or when a reader reports a step that does not match their unit. Each guide shows its “Updated” date and lists the manuals it is based on.
