Culligan AC-30 Control Box

Sometimes when I plug in the control box, the box beeps 3 times then the "Replace RO Membrane" light flashes. BUT, sometimes when I plug in the Control Box, I get no beeps and no lights ever come on or flash. What could be the problem? I have had the system for just about 6 months. I ensured that the electrical outlet is live. Would a bad Control Box cause the Replace RO message to come on? Any help appreciated.

Are you sure the model number is correct? The Culligan AC-30 I see is a under sink RO filter that has no control panel or electrics.
