The Kenmore ice maker M1 SA8868 is manufactured by Frigidaire for use in Kenmore refrigerators sold by Sears. If the automatic ice maker stops producing ice, a number of factors could be involved, from a frozen water line to a full ice bin. By troubleshooting the unit yourself, you may be able to correct minor problems and save on the cost of a service call for repairs that could take less than half an hour.
Open the freezer to remove the plastic bin and dump the ice inside. Lift the wire sensor extending to the right as high as it will go. If the M1 SA8868 does not start within 10 minutes, continue troubleshooting.
Pry off the cover on the front of the ice maker. Turn the nylon gear to the right until it clicks to force the unit to start another cycle.
Insert the electrical connector on the wires at the back of the unit into the socket in the freezer wall to verify that the ice maker is connected. Check the rubber pipe on top of the unit to confirm it is inside the ice maker, not hanging to one side.
Shut off the water to the Kenmore, turning the valve knob under the sink clockwise.
Unplug the electrical cord and pull the Kenmore forward so you can check the back of the freezer.
Grab the metal coupler on the end of the pipe where it attaches to the back of the freezer and turn it counterclockwise with pliers to remove it. Check the tip of the pipe to determine if water is frozen in the line.
Place the end of the pipe in a plastic container to drain the water.
Cut and wind a strip of plumber's tape around the threading on the nozzle that protrudes from the back of the freezer. Fasten the pipe to the nozzle and twist the coupler to the right with pliers until it's tight.
Connect the electrical cord to the wall outlet and slide the Kenmore into position.
Unscrew the valve knob below the sink to deliver water to the ice maker. If the unit still does not make ice or produce any noise, the motor inside the component may have burned out and will require replacement.
