Noisy Refrigerator Unit Remedies.
Hello. I have a few tips and tricks on how to fix, or understand why your refrigerator emits certain noises, at times.
can be annoying. Unit noises are, sometimes, normal, but most are signs
of very serious issues. Any type of knocking, or pinging, will indicate
that there are serious issue that concern the compressors internal
seal, and structure. Normally, these noises will be located at the
actual compressor area. Here are some other common noises that will
occur overtime. These are , generally, repairable and pose no serious
threat to the unit.
Lets start with the common hissing and
popping. Hissing and popping is normal on frost free refrigerators, it
is the defrost heater, in this case. I would check these following
areas to address any other abnormal noises. The next issue will deal
with proper leveling of the unit.
If the level of the unit is
not adjusted to proper specs, this will create an unstable operating
condition, causing many noises to emit from the units structure.
inspect the unit for proper level. adjust if needed. Secondly will be
the drain pan. Once removed for cleaning, the pan must be replaced in
position correctly. If not, the pan will rattle against the compressor,
causing a rattle.Simply reposition the tray if this is the case. The
third possible issue will be the condenser fan. The condenser fan is
located behind the refrigerator. It may be necessary to remove an
access panel to reach it. This fan has a shroud or cover, and if the
fan blade becomes warped, it will rub against the shroud, causing
noise. This fan blade is whole,and it can be removed and replaced if
this is the case. Ok, the fourth problem spot will be the evaporator
The evaporator fan is located at the back of the freezer.
It may be necessary to remove obstructions such as the contents of the
freezer, freezer shelves, ice maker and the rear inside panel of the
freezer, as well. The rear panel may be held in place by retainer clips
or screws. Remove the screws or depress the retainer clips with a small
flat-head screwdriver. Check the fan for warped blades. if the blades
are warped or mis-aligned, replace it. This fan also is protected by a shroud as well, and it will make noise if the fan blade is damaged.
The last area of concern will be the compressor mounts. This is the
most common spot for noise overtime. The compressor sits on rubber
mountings. Those rubber mountings are designed to absorb vibration from
the compressor. As the mountings age, or depreciate, they can become
very hard(Dry rot), or disintegrate. When this happens, the compressor
vibration is transmitted to the refrigerator structure and it can cause
noise.The compressor is located in the rear. It may be necessary to
remove an access panel to expose the compressor. Once exposed, remove
the screw or retaining clip of just one of the compressor mounts.Using
a pry bar, lift up the compressor enough to slip out the rubber mount.
Inspect the mount for deterioration. The rubber should be firm but not
rigid. If the mount is crumbling or hard, it should be replaced.
This concludes the inspection procedure. Follow carefully, and replace any failed or damaged device.
Have a great Day
