The ice maker has a problem
ice maker is a separate appliance within the freezer section. Please
see the How things Work section of our website to learn about the
normal functioning of ice makers. Some common problems with ice makers
are:The ice maker has completely stopped producing ice The ice maker is producing ice poorly
The ice maker has completely stopped producing ice
to see whether the ice maker has been turned off. Here's how to check.
Look for a wire along the right side of the ice maker that looks a bit
like a coat hanger. If this wire is in the raised position, the ice
maker is turned off. On some units you simply lower the wire to the
down position to turn the ice maker on. On others, you lower a small
red plastic lever to lower the wire. If the wire is in the proper
position check the freezer temperature, it should be between 0-8
degrees Fahranheit. If it is warmer than 10-12 degrees, the ice maker
may not produce any ice. Check your door seals and thermostat,
repair/replace as necessary.
The ice maker is producing ice poorly
an ice maker is producing ice poorly--when it produces just a few cubes
or none, or when the cubes are too small--it's usually because of a
clogged water line or a defective water inlet valve.
check the water line attached to the back of the refrigerator for good
water flow. To do that, first turn off the water supply valve. Then
remove the water line from the back of the refrigerator. Next, place
the water line into a bucket and momentarily turn the water valve back
on to test the flow. If the flow is poor, you need to repair, clean, or
replace the tubing or the shut-off valve that supplies the water. If
the flow is good, you may have to replace the water inlet valve.
There's an ice- or water-dispensing problem
ice and water-dispensing system of your refrigerator is quite complex.
Many components work together to provide the ice and water. Aside from
a simple problem of a leaky water tube or a jammed ice chute, most
other components are not user serviceable. We suggest that you contact
a qualified appliance repair technician for such repairs.
