Every once in a while, I hear noises from the top freezer part. I
assumed that it was ice cubes dropping into the collection tray. I put
an empty tray under the cube maker but nothing appears in it after the
There is a handle that when raised is supposed to stop the ice maker
function. Even when up, I still hear the sound.
I found the owner's manual. Here's what it says:
"Certain sounds may accompany the various cycles of
the ice maker. The motor may have a slight hum, the
cubes will rattle as they fall into an empty storage pan
and the water valve may click or “buzz” occasionally."
Problem is, I hear the rattling even if not cubes are falling into the pan.
From here, it "sounds like" (sorry) a bit of a
non issue. If the noise is irritating, it's not
dificult to remove the ice maker in most freezers.
Couple screws, and a wire.

The ice maker makes noises at various points of its cycle - not just
when the cubes fall. There is noise when the tray fills with water,
when the mechanism is changing positions (for example, from make ice
to get ready to dump ice) and when it actually dumps the ice. Your
noise could be one of those or something else entirely. All you say
is "noises" so that makes it hard to disgnose remotely.
The sound is definitely not coming from the ice maker, which is on the
left side of the freezer. More from the right wall, but knocking on it
with my knuckles doesn't trigger the sound. The rattling only occurs
when the motor is running.
Even stranger than the rattling is there is no shut off valve on the
copper water line to the ice maker. The line emerges from the baseboard.
On the opposite side is a bedroom. Bizarre! If the line leaked, I'd have
to shut the water to the entire house off as far as I can tell. I've
been here only a month, so I don't know all the in's and out's of the house.
I get noises a little like ice cubes dropping, and I don't have an ice
maker. When I mentioned it before, it was two or three days before I
heard it again. Then it seemed to happen every time the compressor started.
It might last ten seconds, maybe a dozen knocks, irregularly spaced like
I checked my defrost cycle. It's 10 minutes at 363 watts following by 20
minutes of rest.
I haven't checked to see if it's always 10 minutes of heat. If it is,
that's probably the minimum to keep things working. Depending on the
dew point in the house and how much the door is open while the blower is
running, that might not be quite enough for everything to drip down and
drain. Maybe there's a little ice left on the evaporator, and the
dripping water forms icicles, and they pick up frost. When the blower
comes on, some little icicles break off and are blown into something.
That's my theory. I suppose I could prove it by unscrewing the panel at
the back of the compartment and looking for bits of ice the next time I
hear it. I'm too lazy for that, so I'll assume it's harmless.
Interesting theory. I'll try finding a similar pattern. Yes, the noise
does appear harmless, but I'm a perfectionist, and in all my years (more
than 70), I've never hear such a noise. The house I just sold had a
15-year-old refrig that never made any noise other than the compressor.

I've know of compressors to gurgle when charged. And
who knows? Might be part of the refrigeration system.
As to refrigerators, I've seen R134a. R-410a is used
in newer central AC systems. Some freezers take R404a.
Here's a picture of the bottom rear of the refrigerator:
The problem is in the shock-mounted unit on the right. Its fan has axial
play, about 1/16", that causes the "rattling." With power off, if I rap
my knuckles against the unit, I will hear the rattling every time.
Maybe if I intentionally "unleveled" the refrigerator so the left or
right side is slightly higher, the noise will go away. Even without
taking any further measures, just knowing the source of the rattling is
Thank, everyone, for your comments.
Lucky you, that's plenty of room to work. If you want
to replace that fan, a good appliance parts house can
get you a drop in replacement. A two watt CCW fan motor
called a "unit motor" should run twenty or thirty bucks.
I've replaced those with pretty much no room to work,
and no fun at all.
Please replace the cardboard on back of the fridge, the
cardboard is essential to it running properly.
OK to use some compressed air and blow gun to clean
the dust out of the black condenser, just right of the
fan (as we're viewing the unit).

I like the idea of replacing just the fan motor. I would never that
considered doing that. Here's a video of how to do it:
Here's another video:
At time 4:00 he warns to make sure the screws are tight or else there
could be a rattle. Maybe that's my problem. I'll check tomorrow.
What's puzzling is why the rattling comes and goes during the on cycle
for no apparent reason.
I went to a local parts place for a replacement fan motor. It had the
same amount of axial play as my present one, so I didn't buy it.
As the clerk and I were talking, he suggested the source of the rattling
was the compressor. That does make sense, because the sound does come
from that side of the refrigerator (lower right, looking in from the
front). I can rap the compressor, but it won't trigger the rattling. I
guess it's an amazing coincidence that rapping the condenser coils
triggers the rattling sound, but rapping the compressor doesn't.
There is a loose cover over the electrical connections to the compressor
(not shown in the photo). It doesn't make the same rattling noise, but I
tightened it by wedging several thickness of paper around it. The
intermittent rattling still exists.
Something I hadn't mentioned is that there is a large vertical coil of
copper tubing leading to the ice maker, which "unwinds" as I pull the
'frig forward. With the 'frig in its normal location close to the wall,
I thought the coils might be vibrating against each other, but they aren't.
I'm going to take the advice offered several days ago and just live with
it as long as the 'frig is working.
Thanks, again, to all for your thoughtful suggestions.
Have you tried bending some part of the metal involved, just a little bit,
but enuf to see if that stops the annoying noise. You don't want to bend t
he tubing, but there are other things you could bend. You could also use a
piece of sponge rubber wedged in various locations to see the effect.

The OP can wrap the fan and blade in three layers
of duct tape, if needed. Can't say the fridge will
keep temps, but it will be quiet.
