Manitowoc Ice will not operate after pressing power switch, while holding switch motor starts once switch is release all action stops.
Best bet is to contact Manitowoc technical service at 844-724-2273 MUST have MODEL & SERIAL when calling. Tech info also available on Manitowoc website, but you would have to read all to try and diagnose by yourself.
Any more questions please let us know.
That number (NY0191) you provided isn't a good number.
Don't know if your machine is a cube or nugget(or "flaker") ice machine. Cube machines (cubers) have a rocker switch for selecting ON/OFF/CLEAN modes. Their nugget machine - which I'm not overly familiar with, may be just an ON/OFF toggle switch. Either way, those are both like a light switch. You put 'em there and they should run. If you have to keep your finger on it, then it's no good.
Find the data sticker, get a good model & serial number and, as abialas suggested, call Manitowoc. They may suggest calling a service company.
Sounds like time to call for service.
