I have a kayrack with a Ranco ETC ( the multi voltage on). The error code is E2. The intructions I found there said to check the settings I did. I would reset it by turning the power off and it will turn the compressor of about 30 secs and then E2. I did not have anew control on hand but said I'll order one.
Is there something I am missing here. Or is the controller bad. Thought I had bad wire connection redid some, defrost timer bypassed the same thing. Everything checks out with my meter on them.
