For the symptom you selected, these are the most common parts or causes, ordered by the likelihood of fixing the symptom.
If the ice maker is not working check the temperature of the freezer. If the freezer temperature is above 10 degrees F. (-12C) the ice maker will not work properly. It functions best when the freezer temperature is set between 0 and five degrees F. (-18 to -15C). If the freezer temp is too high make sure the condenser coil is clean and the condenser fan is working to cool the condenser and compressor. Check the evaporator coil for frost. If too much frost is built up the air can't circulate thru the coil and you will need to check the defrost components for a failure.
If the refrigerator ice maker is not working the water inlet valve might be defective. The water inlet valve is an electro-mechanical valve. The coil can show good for continuity and still not let the water thru.
If the ice maker is not working it could be that the ice maker assembly itself is defective. The freezer temp should be between 0-5 degrees for the ice maker to cycle properly. There are several components in the control module of the ice maker that can fail and most are not sold separately. Also, ice makers have a relatively short lifespan and so it might not be worth fixing. If other, simpler parts like the water inlet valve or shut off arm have been ruled out, and the only thing left is the ice maker itself, replace it as a unit.
If the ice maker is not working the water pressure in the house might be too low. The water inlet valve which supplies water to the ice maker is designed to work with a minimum of 20 psi of water pressure.
If the refrigerator ice maker is not working, the door switch might be defective. When the freezer door is opened the freezer door switch does two things, it turns on the light in the freezer and turns off the ice maker and dispenser. If the door switch fails the dispenser will not turn on. The switch can be checked for continuity with an Ohm meter. If it doesn’t have continuity it should be replaced.
If the ice maker is not working the ice level control board might be defective. This refrigerator is equipped with an infrared light beam to detect the level of ice in the ice bucket. As the level of ice reaches the top, the beam is interrupted and the ice maker shuts off. As ice is used up and the level of ice drops below the beam, the ice maker starts up again. If the ice level control board fails, the ice maker will stop making ice.
If the refrigerator ice maker is not working the water filter might be clogged. Try changing the water filter.
If the ice maker is not working the icemaker mold thermostat might be defective. Inside the control module of the ice maker is a thermostat which monitors the temperature of the ice mold (ice tray). Once the mold reaches the proper temperature the ice maker starts a harvest cycle by ejecting the ice cubes and refilling with water. If the mold thermostat is defective the ice maker doesn't advance. The thermostat can be checked for continuity. Replace it as needed.The freezer temp should be between 0-5 degrees for optimum performance.
If the refrigerator ice maker is not working, check the icemaker switch. This switch frequently gets turned off by accident. If the switch is turned on but the ice maker still doesn't work, check the switch for continuity with an Ohm meter. Replace as needed.
