Hi there, Thanks so much for asking about this. According to page 26 of the user manual for this model (linked below) the "Ice Off" button, located on the far left of the control panel, will turn the ice maker off.
However, I would also like to provide the following link to our troubleshooting guide for ice maker issues. It has step by step instructions on what to do if the ice maker is icing up.
Once these steps are completed, if the ice maker is still freezing up, the unit will require service. There are a few options here we can take based on your warranty status.
If you’re in the one-year manufacturer’s warranty, please gather together the full model and serial number of your unit, and have ready your name, street address, 2 phone numbers (Best contact, alternative number), email, and place of purchase. Provide this information to an agent, in one of the following options below:
1.) Reach out to a Moderator directly, by selecting our name and the message option. When messaging please use a link to this thread in addition to the info above.
2.) Reach out to us on Facebook or Twitter. Please provide the same info as above, as well as the link to your thread.
