Refrigerator won't stay running

I can turn this fridge on and it stays on for a day or two it even makes ice, but today it was off again, shut it off then turned back on it started back up couple hours ago and its still running. Not sure if its going to work or shut back off again.

Remove the control panel. When it fails, tap on the cold control, or the defrost timer. You will find one is sticking, probably the cold control.
