Was working perfectly. The ice bin on the freezer door had exploded soda on it so I removed it to clean. Let all the ice melt out, cleaned and reinstalled. Now it doesnt make any ice. It has been like this for several months. There is a piece of plastic that moved but broke off in the upper left of the freezer. I attached a picture. That happened years ago and ice maker still worked. Any advice on what to do/check? Water dispenser still works. Thanks!

Also is there an epoxy/super glue you recommend for plastic in the fridge?

It may be possible that residue could have gotten onto the optics. If you use a Q-tip to clear the emitter and receiver optics (the lens ports of the plastic covers on the left and right of where the bin would sit when the door is closed), does it start to work properly in an hour? Also, what temperature is the freezer reaching when verified with a thermometer?

Thank you so much for your reply. Could you show me on the pic where the optics are? Also, is there a way to “force” the water into the ice tray? Just to make sure line isnt blocked/frozen? Ive fixed our washer, dryers, dishwasher, etc…but this fridge…i feel so lost.

The optics lenses are in the ports of the covers as seen in the attached images. To force cycle the ice maker, move the right optic shutter to the off position. From there, dismount the ice maker (see attached link for reference) while still leaving it plugged in, then remove the motor cover. This would be a good time to check the fill tube for an ice blockage. Use a 2 or 3 inch section of wire with 1/4" of each end stripped of insulation. Use the wire to jump from port T to port H, and have the wire bent enough to be able to pull it out when the ice maker is mounted back in place. Once the ice maker is mounted in place, open the optics shutter to start a harvest cycle. After about 15 seconds, remove the wire by pulling it to the wall then removing it. The ice maker should continue a harvest cycle. This will test to identify if the ice maker sends voltage to the water valve, as well as if the valve sends water to the ice maker once it receives voltage. Let me know what you find and we can go from there. https://www.youtube.com/watch?v=aKolPRgXIgk
