Defrost Drain Hole is Plugged
This is usually the problem when a sheet of ice forms on the floor
of the freezer.
In automatically defrosted models, water from the melting frost
flows out a drain in the floor of the refrigerator and into a pan,
where it evaporates. Food particles can be carried along, clogging
the drain and causing odors. Clean the drain regularly by following
- Remove the stopper.
- Use a pipe cleaner or similar device to push any
accumulations through to the drain pan below.
- Force a solution made from soap, ammonia, and water through
- Empty the pan and wash it.
From time to time the drain systems on some frost free
refrigerators can become clogged. When
this happens, cleaning water from under the crispers may become a
daily task. On designs that have the freezer near the floor, you'll
notice more and more ice building up. Whatever the design, this
situation should be repaired as soon as possible, for if allowed to
continue, more serious problems to your refrigerator cabinet could
result. Problems such as wet insulation, burnt out drain trough
heater, fan or light switches shorting out just to name a few.
Because of the vast number of variations of designs that have
evolved over the years, how to clean out and flush your particular
drain system will require a bit of innovation on your behalf. This
is not a complicated procedure, and once you understand some of the
general principles, how you do this will become straight forward.
The purpose of the drain system is to provide a path for the
condensate water to flow by gravity from the drain trough under the
freezer coils to the condensate evaporator tray. Here this water
will be evaporated back into the air by heat, once the hermetic
system starts up again after the defrost cycle is complete.
Note: Some newer uncommon designs don't use any
fittings or tubes. The defrost drain water trickles down the back of
the refrigerator section and flows down a drain underneath the
crisper, which is very prone to clogging.
