The dreaded 'Ll op' code on reefer

[Nedbrod]

Well I just got the dreaded "Ll op" code on my Norcold 2128 reefer. I looked in on the control panel as indicated by so many previous threads but found that the little red led was not lit. I did the magnet trick on the control as recommended anyways but didn't hear any click from the control. I'm getting 12v on the positive terminal of the control and the temp sensor is showing continuity but still getting the blasted code. Any ideas on what else to look at? Thanks.
