sears side by side refrigeration ice maker is not working flashing in red what can I do


The second link provided above gives some troubleshooting for this type of problem on the ice maker system that you have. The red LED light flashing twice and repeating is normal when the infrared level sensing beam is blocked by the flapper door. Make sure that the ice maker switch on the right side of the freezer is in the on position so that the receiver eye is uncovered. Close the flapper door to unblock the beam and see if the LED light turns solid red. If it does then this indicates that the emitter and receiver boards are okay. If the red light does not turn solid when the infrared beam is unblocked then the emitter and receiver control boards will need to be replaced as shown in the first image below. Be sure that you unplug the refrigerator to disconnect electrical power before accessing these internal components. The part number of the kit that has both of these control boards is 4389102. You can order this kit from the Sears PartsDirect website.

If the emitter and receiver boards are okay, you can check the water valve as described by Scott D. in the second like provided above but you will need to unplug the refrigerator and place an insulated jumper wire in the harness of the receiver control board (on the right wall of the refrigerator) as shown in the image below. This will provide you with a dependable power source to check the water valve. You can unplug the receiver board as shown below. The insulated jumper wire can go between the yellow and black/white wire as shown the third photograph of the second image. If you jump these wires, the water valve will not activate unless you push the door switch for the freezer in. This would give you more control of the test once you plug the refrigerator back in with the L and V contacts jumped on the ice maker module and the yellow and black/white wires jumped on the receiver board. Place a cup or container under the water inlet spout and press in on the door switch to see if water flows from the spout. If it does then the water valve and wiring to that component should be okay. If you jump the black and the black white wires (with the refrigerator unplugged) then the water valve should active as soon as the refrigerator is plugged back in with the L and V contacts jumped on the ice maker module.

You can unplug the refrigerator and place the jumper in the black and black/white contacts then follow the procedure shown in the third image below to cycle the ice maker module and check its operation. Jumping the black and black/white wires will provide constant power to the ice maker instead of depending on the receiver control board to apply that power to the ice maker module. You can also reconnect the receiver board and follow the procedure shown below to cycle the ice maker module. If the ice maker module will cycle when the T and H contacts are jumped with an insulated jumper wire but will not cycle normally in the freezer when it is at the proper temperature (around zero degrees) then the ice maker module likely has a bad thermostat or other contact failure and will need to be replaced. You can order an ice maker module (part 2198597) from the Sears PartsDirect website.

This ice maker system is complicated to diagnose. If you are not completely confident in your technical ability to properly perform the tests and safely insert the jumper wires as described above, I recommend that you have a service technician diagnose and repair this ice maker problem.
