Winterizing and De-Winterizing the Residential Refrigerator
To avoid freeze damage, all water needs to be evacuated from a number of areas
including the ¼” supply line to the refrigerator, the reservoir coil inside the
refrigerator, the ice maker and water dispenser lines inside the refrigerator, the ice
maker and water dispenser solenoids inside the refrigerator, and the drain valve
under the slide out (if so equipped). While winterizing is usually thought of as
something that is used while storing the RV for the winter, you must also protect
the exterior portion of the water supply line to the ice maker when the RV is in use
and the temperatures are projected to drop below freezing! The ice maker shut-off
valve is normally located under the kitchen sink.
Using the Drain Valve
Starting with early builds of the Residential Refrigerator option, a drain valve was
installed on the trailer frame, underneath the refrigerator. By opening this drain,
you can evacuate some of the water from the refrigerator. However, there is
approximately 1 quart (1 liter) of water inside the refrigerator and some
components may retain water even if you are successful in draining about a quart.
Antifreeze Method
While using RV antifreeze will protect the components from freeze damage, there
could be issues with taste of the water and ice. With PEX water lines, antifreeze
flushes out and taste usually returns to normal very quickly after de-winterizing.
However, the 1/4" water supply line is a different material. Some owners have
found that the supply line, solenoids, and reservoir may retain the taste of
antifreeze for a longer time.
Using Compressed Air to Winterize the Refrigerator
Using compressed air at 40 psi or less to evacuate water from the ice maker and
water dispenser and related components is the safest, most thorough and cleanest
method available. The downside of course is that you’ll need an air compressor
and appropriate connectors to use this method.
NOTE:
If using RV antifreeze to protect the rest of the water system, the refrigerator
procedure should be completed first, before introducing antifreeze into the RV's
other water lines.
