Not every appliance issue needs a technician. A few checks can save you a service call — and a few others are exactly when you should stop and call one.
Refrigerator not cooling
- Confirm the RV is parked level — absorption-style RV fridges rely on gravity to circulate their cooling fluid and can stop cooling properly if the rig is off-level.
- Check that it’s actually receiving power or propane, depending on the mode it’s set to, and that the mode switch matches your hookup situation.
- Check the roof vent and exterior access panel for blockages (insects, debris, or a bird’s nest are more common than you’d think) — restricted airflow behind the fridge is a frequent cause of poor cooling.
Water heater won’t ignite
- Confirm the propane tank isn’t empty and the shutoff valve is open.
- If you recently winterized or de-winterized, double check the bypass valve is in the correct position.
- Check whether it’s set to gas, electric, or both, and confirm it’s getting the power source it needs.
Furnace not blowing warm air
- Check the thermostat batteries first — an easy miss.
- Check your house battery charge. Even propane furnaces depend on 12-volt DC power to run the fan and ignition system, so a low battery can stop a furnace with plenty of propane from working at all.
- Confirm the propane supply and that nothing is blocking the intake or exhaust vents on the exterior of the RV.
When to stop and call a professional: if you smell propane (often described as a rotten-egg odor), don’t troubleshoot — shut off the tank if it’s safe to reach, ventilate the RV, avoid any open flame or switch, and get everyone out until it’s been checked. The same goes for a refrigerator’s sealed cooling unit — these use pressurized ammonia and should never be opened or repaired as a DIY project. And test your carbon monoxide and propane detectors regularly; the U.S. Consumer Product Safety Commission notes CO poisoning symptoms can resemble the flu at lower exposure levels, which is part of why it’s often missed early.
