We recommend running a full cleaning/descaling and sanitizing cycle to resolve this issue. You can find the instructions for this starting on page 7 of the Use and Care Manual here: https://products-salsify.geappliances.com/image/upload/s--1jfWxVD5--/sucedrcowdih1xgqteu1.pdf. Please note, to ensure proper performance, we do recommend only using distilled water in your Opal.

We do see a member of our team is working with you and recommend continuing to work with them as they will be best to help assist. In the meantime, we have troubleshooting and the normal operating sound that you can expect to hear from your Opal unit from a couple articles on our website that you can view here, Opal sounds: https://products.geappliances.com/appliance/gea-support-search-content?contentId=35276&_gl=1*. Troubleshooting: https://products.geappliances.com/appliance/gea-support-search-content?contentId=35289&_gl=1*.

We are happy to provide guidance with Opal sounds. When your Opal is in need of defrosting, it may start to squeak as ice starts to build up around the mechanisms. The defrost cycle is automatic and may take 10 to 45 minutes. The screeching you're experiencing can be the result of the appliance needing to be descaled. To descale, fill the reservoir with hot vinegar (100-120°F) to the max fill line and run up to three cleaning cycles. When using vinegar, leave the vinegar in the unit for 18 hours and set a vinegar-soaked towel on the ice chute overnight to further dissolve any mineral build-up. Clean the sensors with vinegar and wipe clean with water. After draining the vinegar, run three rinse cycles using fresh water for each rinse. If the tips provided do not help, please contact Opal Ice Maker Support by calling 1-866-907-6718.

The Opal side tank isn't designed to come apart as shown in your video. We recommend calling the Opal support team at 1-866-907-1655 for further assistance. If needed, installation information for the side tank can be found on page 13 of the Owner's Manual: https://images.salsify.com/image/upload/s--1jfWxVD5--/sucedrcowdih1xgqteu1.pdf.

We’d like to assist with this issue you’ve had with sound. We recommend ensuring there’s at least 4” of clearance around the Opal on all sides and on top to allow for proper air flow. We also suggest following the cleaning instructions that start on page 7 of your manual; that’s linked here: https://images.salsify.com/image/upload/s--9_JHdteK--/248fcfa1db27d93cf26d2d04dad1f2db57a3f5f1.pdf. Running full descaling and sanitizing cycles can often help with an issue. Using vinegar in the descaling cycle can also help break up minerals that may be impeding optimal operation. We suggest filling both the internal reservoir and side tank with water, rather than only the side tank. You can also reset the Opal by disconnecting it from power for 3 to 4 hours before reconnecting. We recommend only using distilled water in your Opal to help reduce the potential for mineral buildup. It’s important to note that distilled water is different from bottled water, reverse osmosis water, filtered water, or spring water. All of these other options contain varying levels of minerals that can build up in the unit and impede optimal operation. Using distilled water reduces the frequency of descaling and cleaning. Using our scale-inhibiting filter, part P4INKSFLTR, is designed to increase the time between cleanings and reduces the solidification of scale. We’ll be reaching out over email to discuss your situation further. We look forward to hearing back from you, so we can assist.
