Did you drain all of the water out of the ice maker line when you winterized? A couple years ago, I winterized my ice maker by running pink stuff all the way through. The solenoid ( cheap piece of junk plastic housing ) housing froze anyway and split open. I purchased a new solenoid, but when I installed it, I left the water line off of it and closed it off with a valve. I never use the ice maker anyway.
