Having an ice maker built into your freezer can make things a little easier around the house. You don't need to worry about filling ice trays and carefully carrying them across the kitchen without spilling the water on the floor. You don't have to worry about knocking the trays over in the freezer before the water has frozen, but, you do have to worry about what to do when the ice maker doesn't work exactly as it should.
If your ice maker makes too much ice, or doesn't shut off when it should, there could be one of two things wrong – the shutoff arm could be failing or the shutoff switch may no longer be working. Below, you will learn how to test each of those elements.
Checking the shutoff arm is rather simple, especially if you understand how it works. It is an arm-like piece that rises up as the ice is made and drops back down when the ice is emptied. When the ice bin is full, the arm is raised and engages a shutoff switch preventing the ice maker from producing any more ice until the ice has been used. Then, when the arm lowers, the ice maker will produce more ice to fill the bin and raise the arm back up.
To test the arm, check that it is firmly supported from the back of the ice maker. If it doesn't seem to fit snugly, it may have become worn out and needs to be replaced, or it could just need snapped back into position. Give it a gentle push into place.
To test how well it is functioning, lift the arm to its highest position and walk away for a bit. Check an hour or so later to see if the ice maker had created more ice or if the shutoff position has worked. If it has continued to make ice, the control module may need to be replaced by your local appliance repair technician.
The shutoff switch is housed inside the component unit on the back of your freezer. This test can get complicated if you aren't experienced working with appliances, so only proceed if you have that experience.
Remove the screws holding the faceplate onto the front of the component unit. Open the unit and look for the small arm-like piece that comes from the side of the box. Remove the wires that are connected to the terminals closest to that arm. Use a multitester to test the connections by setting the tester to an ohms setting of X1. Touch the side terminal with the probe and one of the other two terminals. You should get a zero reading.
Now, with the probes still in the same position, press down on the lever on the side of the unit. The reading should now be opposite. If it isn't, you need to replace the shutoff switch.
