I have an ice maker in my side by side Whirlpool fridge. It will drop
a load of ice about once every two weeks. Other than that, it just
makes noise. It's like a grinding noise. I believe it's the motor
because I can feel the vibration when I put my hand on the large gear
that the motor runs. Besides, what else could be making noise? An
icicle slowly grows from the cub tray downward. With the fridge
unplugged, I read 72 ohms from a digital multimeter between the "L"
and "H" test points. This is exactly what my fix-it-yourself book
says it should be so I think the heater element is good. Between "L"
and "M" I read a very low ohm value, not zero though. This reading
was read with a cheapo analog meter because the 9v in the digital
died. Here are my guesses at possible problems:
1) Although the heater element is good, something is wrong with the
controls to turn it on and off. It's not cycling correctly and not
melting the ice enough for the motor to turn.
2) Something mechancical is jamming the motor. Motor doesn't have
enough torque to drop the ice. Either a faulty motor or something
down the line is physically jammed.
3) A stripped gear. This is hard to see because of the cover over
the motor gear. Maybe I can remove the motor and inspect the gear.
As I re-read this email this seems like the most likely, almost
obviously so, culprit. As soon as I get home today, I will check this
If anybody has any wisdom to share, I would sure appreciate it. These
things are cheap enough that I should just replace it but our budget
is so tight right now I could only afford to buy some new cube molds.
Thanks in advance,
Poor but handy,
You'll want to replace the module, prt # 628366. I get
around $60 for them. Includes the entire front of the
icemaker, motor and commutator. Basically replaces
everything functional except the tstat and heater, which
Yours is a common problem, and it's not feasible to
repair these motors, and they aren't available separately -
must buy the whole module.
It's an easy part to replace, too. Remove 3 screws, pull
the old one off, push a new one on, replace the 3 screws.
It's always a good idea to check the fill level when you
do this, though. Jumper T & H and catch the fill in an old
baby bottle (graduated in cc's). 140-145 cc's per fill is
ideal. There's a small adjustment screw on the right side
of the module. Only yields a small amt of adjustment, but
try to get it as close as poss. They'll run with as little as
100 cc's, but lower fills will cause problems.
Hope that's of some help...

Here is a follow up. I have checked the gears and there is no missing
or damaged teeth. It is a module type that makes crescent shaped
cubes. How can I be sure that it is the module? I can't afford to
buy a module and then be wrong and have it be the heater. I have
definitely elimitated the valve as a problem. As the motor makes its
noise, I can watch the big gear rotate back and forth almost
imperceptibly. Is there another set of gears inside the motor that
could be stripped and causeing the noise and this back and forth
motion of the large gear? Can someone take me through diagnosis step
by step or at least give me a detailed list of steps that the machine
goes through to make and dump a load of cubes so I can understand it

Certainly *sounds* like a bad module....any cubes stuck inside the
Motor or gears don't have to be stripped to be bad, also has a printed
circuit under that main gear, motors inside could be bad as well. Some
