We'd like to assist with your Opal ice maker's squealing sound. When your machine starts to make a squealing sound, it's a sign that the unit has ice building up on the mechanisms. The unit needs to defrost, so that the ice can melt away from the mechanism. This process can take up to 45 minutes to complete. You can unplug the unit for 30 minutes to allow it to reset and plug it back in. You can find more information on defrosting and additional suggestions on the article titled "Opal Ice Maker Dispenser - Defrost Issues" on our GE Appliances website. You can view this article on our website when you put the name of the article in the search bar and then click on the “Support” tab. If the issue continues, please send us a private message via Facebook, Instagram, or X with your contact information, complete model/serial numbers, and a copy of this review so that we can review the information and get back with you quickly.
