Modern ice makers come with an electric heating unit, an electric motor, and an electronically operated water valve. You need to attach the device to the circuit which powers your refrigerator, so that all these elements get the necessary power to perform. Also, you will have to connect it with the plumbing line in your house, so that it has the continuous water supply needed to generate ice cubes. Both these lines go through a hole present behind the device.
Fixing an Ice Maker
Before starting the troubleshooting process, it is important to look at the functioning of your ice maker, as it varies from manufacturer to manufacturer, and model to model.
No Ice Production
If your ice maker is not producing any ice at all, it could be due to various reasons. Firstly, check the right side of the machine for a wire. The wire will be in an erected position, if the machine is turned off. In such a case, lower the plastic lever present in there or the wire directly, if there is no plastic lever. This should be enough for your device to start functioning once again.
There could also be a case of blockage in the fill tube. If this is the situation, use a hair dryer to melt any cubes stuck in there, which is causing the blockage. Replace the tubes if necessary. Check the assembly for any cracked or broken parts. Especially check the gears and plastic arms along the ice rake, as these are more likely to break down compared to other parts. Replace them if needed.
Small and Less Ice Cubes
A faulty thermostat, a choked up water line, or a defective water inlet valve could be the root of the problem. There will be a water line behind the refrigerator which you need to check for proper water flow. In case of water not flowing properly through this pipe, clean or replace it. Inspect the water inlet valve and get it changed if it has broken down. Set you freezer temperature to not more than 8 degree Fahrenheit, for ensuring a correct ice formation cycle.
Leakage or Overfilling
A small leak can be caused due to a crumpled water line, while a substantially large amount of leakage could be caused due to a major failure of any part. In either case, check whether the refrigerator and ice maker are leveled or not. If you notice any component is malfunctioning, get it replaced immediately.
No Release of Ice Cubes
Sometimes, even though ice is formed perfectly fine, it does not eject out of the trays. To solve this problem, you need to check the ejector gear and motor for any fault, and replace them if necessary. Also, test the thermostat as the problem could be because of its malfunctioning.
Ice Formed Has a Bad Taste or Smell
The primary reason for the ice smelling or tasting bad, is food odor getting mixed in it. You should ideally wash and clean interiors of your refrigerator to do away with the foul smell. Also, take out any food lying in the fridge for a long period. Apart from this, also check the water inlet valve, change the water filter in your fridge, and flush out the supply line if the problem still persists.
Repairing an ice maker becomes simpler if you refer to the manual. If you are not able to do it yourself, you can always call for an authorized person, who specializes in this kind of repair.
