    So we have this controller showing this 'E2' code. The controller's paperwork says it is a "memory error", and that "the control settings are not properly stored in memory"... "To correct: Check all settings and correct if necessary."

    There are other codes that the paperwork says to replace the control, but not this particular code.

    I have done everything I can think of short of replacing the control, which I don't really want to do if I don't have to. The thermister is good, and any new settings for set point and differential do not want to be saved.

    Where is the magic reset button... or did this thing let the smoke out when I wasn't whatching?

    If you take the four screws out and look inside the cover there's a little black switch flip it and she will work. If I remember right.

    I just had this happen on one a week ago. Nothing I tried would get rid of it. Also couldn't set it to the right temp, it would go back to 198°.

    Replaced the control.

    E2 Error code.

    Replace the controller. Don't even mess with it anymore. You may get lucky with a power hard reset, but it will only fail again in short order.

    The dip switch is to unlock or lock the settings. Has nothing to do with the memory of the controller itself. All it does is lock the front buttons so the consumer does not have the ability to change the temperature setpoints and differentials.

    They must have sent out an electronic signal to cause these things to fail.
    I have one, same code, the differential keeps going to 60*.
    I have a replacement out in the van

    Johnson Controls' identical version. Have always used the Rancos. Other than the paint and brand, is there a difference? Even the prices of these things are similar.

    Seen a bunch of the Ranco controls fail, not the Johnson, they stand the test of time and we only get the Ranco if a customer insists.

    The Johnson Controls model is NOT compatible with the Ranco temp probe assembly. Or at least it wasn't last time I tried to make it work.

    And if you work on some the same units I do.....its a complete bitch, nearly impossible to run a new temp probe and secure it in place. With the Ranco, all you do is switch out the controller...no need to run a new temp probe if its still perfectly operational.



    With that being said, I am much more a fan of JC controls than Ranco. I carry one Ranco just for those specific units. But everywhere else, I go JC when given the opportunity.

    Yeah, if replacing the probe is a PITA then get another Ranco. Most likely the Ranco will last a good, long time. It's just my personal experience that I have seen more Ranco fail than JC. Then again, I don't do a whole lot of refrigetation and that's where I do see the Ranco, when I see them.

    Noted. I figured the probes would be different. This particular application will be a breeze to swap the probes. Going with the JC controller.
