DIAGNOSIS The power supply isn't reaching the control board. The main culprit is the power switch on the back. It's shipped in the OFF position.
FIX Locate the rocker switch on the rear panel. It's near the power cord inlet. Flip it to the ON position. You should hear the compressor click and the control panel lights will activate.
IF THAT DIDN'T WORK Check your outlet with a known-working device. The ICEB26AQ draws about 1.5 amps. A weak or GFCI-tripped outlet won't power it.
HEADS UP After first power-on, the unit needs 6-8 minutes to initialize before it will start an ice-making cycle. Don't panic if it sits quietly.
