The power to the ice maker module is provided through the receiver control board. If this control board experienced a power glitch or surge through the electrical lines, you may be able to reset it by completely unplugging the refrigerator to completely disconnect electrical power for 5 minutes. After plugging the refrigerator back in, the board may resume normal operation.
The receiver board has an automatic diagnostic feature. When you open the freezer door, the status LED light on the receiver board should flash twice, pause for 1 second and repeat the sequence as long as the freezer door is open. If you push in the flapper cover on the emitter side and do not obstruct the beam between the emitter and receiver boards, then the status LED should stop flashing and stay on constantly. The optics diagnostics are explained in more detail in the first image below.
If the optics are working properly, then you could have a problem with the ice maker module. The procedure at the bottom of the first image shows how to insert an insulated jumper wire in the T and H terminals of the ice maker module to manually force a harvest cycle in the ice maker module. This procedure is intended for technicians. If you are able to safely follow the instructions for this procedure, you may be able to test your ice maker module and determine the cause of your failure. Carefully follow the procedure if you attempt this test. Do not leave the jumper inserted in the contacts for longer than necessary as noted in step 9 of the test. You can damage the ice maker if the jumper wire is left in the ice maker module for too long. If you are not completely confident in your technical ability to safely complete these procedures, I recommend calling a service technician to diagnose and repair the ice maker.
