Tips for avoiding RV fridge problems on the road
 |
| Life without a refrigerator isn't fun. Take a little care with our own and save problems down the RV road. |
Before driving off to explore America this summer, RVers should take a
few moments to properly service and maintain their recreational
vehicles' refrigerators.
An expert at Norcold, a leading manufacturer of RV gas-absorption
refrigerators, advises an annual checkup at a local dealer or service
center to optimize refrigerator performance and help prevent problems
on the road.
"RV refrigerators have very different maintenance requirements than
their home-use counterparts," said Raphael Hernandez, Norcold's
technical support manager. "Unlike at home, for example, 90 percent of
RV refrigerator failures are caused by dirty burners.
"Annual cleaning and inspection, performed by a qualified service
technician to avoid propane leaks, should be standard procedure to
prevent problems -- and also helps RVers maintain their refrigerators'
warranties."
Day-To-Day Procedures
In addition to annual service, Hernandez said there are many day-to-day
procedures that RVers can perform to assure proper functioning.
Periodically, especially after long periods of storage, RVers should
inspect vents, the ventilation pathway and refrigerator flue to assess
that they are clear of debris or other obstructions caused by animals
or insects.
To ensure a RV refrigerator reaches the proper internal operating
temperature, Hernandez said, a large model should be pre-cooled for at
least eight hours before it's ready to store food.
There are many tips for storing food properly and avoiding spoilage, he
said. For example, pre-cool food in a home refrigerator before placing
it inside a unit. Also, he noted, inserting warm food in a warm RV
refrigerator can "double its cool-down time."
Most gas-absorption refrigerators don't have internal fans, so their
cooling efficiency depends on air circulation inside the unit. For best
results, pack food loosely and don't line shelves with paper.
Hernandez said frost build-up on cooling fins inside the refrigerator
isn't a problem unless it becomes so excessive that it affects cooling
performance. To reduce frost, limit the time that refrigerator doors
are open and avoid storing fresh or warm foods - they release water
vapor - in open containers.
Defrosting Tips
To defrost a gas-absorption refrigerator, Hernandez recommends that owners:
--Remove all food and turn off the unit
--Place a pan or tray of warm water in the fresh food and freezer compartments to speedup the defrosting process
--Use at least a half-gallon container to capture water exiting the drain hose at the rear of the refrigerator
--Use dry towels to soak up water from melting frost
--NEVER remove frost with hot water, fire, knives or hair dryers -- they'll damage the unit.
Lastly, Hernandez strongly recommends always parking a RV on a fairly
level surface. Because gas-absorption units use a gravity-flow system,
being on an angle of more than three degrees for extended periods of
time stops the refrigeration process.
Consumers only need to utilize these few simple and effective do-it-yourself tips to properly maintain their RV refrigerators.
