Freestanding Ice Maker: Making noise
A failing compressor, bad condenser fan motor or faulty drain pump can cause loud noise from the ice maker. If the compressor is making a loud noise, a service technician should repair the ice maker because a compressor repair involves the recovery and recharge of the refrigerant, which is tightly regulated by the Environmental Protection Agency (EPA). If the condenser fan motor is making noise, unplug the ice maker and replace the condenser fan. If the drain pump is noisy, unplug the ice maker and clear any debris you find in the drain pump. If the drain pump is clear, then you'll likely need to replace the pump because the motor is failing.
The recirculation pump can be noisy if water level in the reservoir is low. A problem with the water supply or a failed inlet water valve can cause this problem. If water level in the reservoir is low, check the water supply. Unplug the ice maker and shut off the water supply cut-off valve. Disconnect the water supply line from the ice maker and place the end of the water supply line in a container. Briefly open the water supply cut-off valve and check for water flow from the end of the water supply line. If no water flows through the end of the supply line, have a plumber fix the water supply going to the ice maker. If water does flow through the supply line, you'll likely need to replace the water inlet valve because it's not opening to allow water to flow into the reservoir.
If the recirculation pump is noisy and the reservoir is full, you'll likely need to replace the recirculation pump because its motor is failing or its impeller is damaged.
Replace the ice maker recirculation pump
The recirculation pump is in the water reservoir. The recirculation pump distributes water over the evaporator plate to form the ice slab. If the recirculation pump is getting the proper voltage but isn't running or pumping water, replace the recirculation pump.
Replace the ice maker water inlet valve
The water inlet valve is behind the lower front grill of the ice maker. The water inlet valve opens to fill the water reservoir when the ice maker first starts and to replace water the freezes on the evaporator plate. If the valve doesn't open or gets clogged with debris, replace the water inlet valve. Also replace the water inlet valve if it fails to shut properly.
Replace the ice maker drain pump
The drain pump removes water from of the reservoir as needed during the ice production process. The drain pump also removes water from ice that's slowly melting ice in the ice bin. If the drain doesn't run when energized or fails to pump water when running, replace it.
Replace the ice maker condenser fan motor
The condenser fan pulls air through the condenser coil to condense the refrigerant to a liquid during the refrigeration cycle. If the condenser fan doesn't run when energized, replace the condenser fan motor.
