On the 9100s there are two distinct blinking patterns depending upon what the problem is.
1) If the AC light is blinking twice, pause, blinking twice, pause.
The unit is seeing AC voltage but it's either too high or too low - Using a voltmeter check the AC voltage at the outlet the refrig plugs into - this generally means it's either under 108 or over 132 Volts AC
2) If the AC light is blinking once, pause, blink, pause.
The unit is seeing no AC power at all. On the back of the refrig remove the cover to the control board. Inside you'll find a small glass fuse, should be 5AMP rated - check it. *Unplug the AC line before removing the control board cover - even if the fuse is blown there will be AC voltage present on the fuse holder..
