In the rush to get the RV ready to roll in the spring, appliances are sometimes overlooked. A complete checkup of the major RV appliances will take time, but the appliance checkup can be easily worked in with a general inspection and systems check.
Appliances should be tested in all three modes (12V, shore power, LPG in that order) if appropriate.
Before Starting a Spring RV Appliance Checkup:
- Reset any breakers that were turned off in the fall; re-install any fuses removed before storage
- Plug in any appliances that were unplugged for storage
- Test any Ground Fault Circuit Interrupters (GFCI) for proper operation
Generator
- Change the oil and filters if these were not done before fall storage
- Inspect the exhaust system for any damage (rust, blockage, loose connections, damaged spark arrestor)
- Mark Polk of RV Education 101 suggests, "Start and run the generator for one hour with at least a half rated load on it. Consult the generators owner manual for proper load ratings."
Battery
- If the RV (coach) battery was removed in the fall for storage, reinstall it
- Clean the terminals and clamps
- Check the electrolyte levels and the state of charge
- Recharge if required
LPG (Liquid Propane Gas)
An annual LPG leak test and gas operating pressure test performed by qualified technician is highly recommended.
- Remove any protective covering put over LP gas vents in the fall to keep out insects
- Check for bee or wasp nests or clusters of flies in vents and air intakes; either can prevent an appliance from operating properly
- Check the certification date of the LPG tanks
- Inspect the tanks for physical damage and touch up any dings with rust-proof metal paint
- Ensure that there is sufficient gas in the tanks for the checkup testing
- Turn the LP gas valve on and check the operation of all LP gas appliances
If a gas appliance is not operating properly have it inspected by a qualified technician.
Electrical (Shore power)
- Inspect all cords and connectors for visible damage
- Test the monitor panel for proper operation.
Checking the RV Appliances
Refrigerator
Be sure the rig is reasonably level before testing the fridge.
Each cycle of the refrigerator will need sufficient time (complete cool-down takes four to six hours) for it to cool in order to check for proper operation. After each cooling cycle, turn the fridge off and leave the doors open to allow the unit to recover to room temperature before the next cooling test.
An RV refrigerator is typically most efficient in LPG mode. If it does not cool somewhat on all three power sources, take the rig in for professional testing and servicing.
- Run the unit on 12V if fridge has three-way operation. The power controller should prevent excessive battery drain
- Plug the unit in to shore power. Cycle the fridge in 110V mode
- The final check will be in the gas mode. Remove the lower vent cover and check for a clear blue flame
Water Heater
- De-winterize (Flush out the heater, turn off bypass, and reinstall the drain plug)
- Be sure the water heater is full of water before testing
Furnace
- Check that air intake and exhaust vent are clear; remove any covers
- Turn the thermostat on, allow to come up to temperature
- Check each hot air vent for air output
Air Conditioner
- Clean or replace air conditioner filters if it wasn't done prior to storage a
- remove any covers that were put over air conditioners
Stove/Oven
- Check the operation of each burner for a clear two-tone blue flame
- Check ignitors for prompt burner turn-on
- Check oven for operation
Check the remaining 120-volt appliances (microwave, sound system, entertainment center, TVs, all counter plug-ins etc.) for proper operation.
The appliances in an RV are part of the experience of a home-on-the-road. Most RV dealers will offer appliance inspection as part of their spring RV maintenance and inspection package. A regular spring RV inspection will go a long way to having appliances run throughout the season, ensuring both safety and convenience.
