It appears my ranco temp controller has crapped out. It works for a few minutes then I get an E-2 error message. I have unplugged it for a while and checked all the connections to no avail. Anyone have any idea what it might be? A bad probe? |

Says the "E-2" error message means:
"Appears if the control settings are not properly stored in memory.
To correct: Check all settings and correct if necessary"
An error code of "EP" means that the probe is open, shorted, or sensing an out-of-range temp.
Not a lot of help, but that's all I can find.

Thanks Paul,
Thats pretty much what I had found too. I have reset the setting with no luck. It looks like it needs to be replaced. I had a spare Johnson controller I hooked up.
Any preference of Ranco vs Johnson controllers? |

I've only used a Ranco ETC digital control in the brewery. My old Johnson controller is analog with a capillary tube. It'd be OK for a freezer controller, which is how I used it until the freezer went tits up.
But I use the Ranco to control my electrically heated HLT, where I want a little tighter control. |

Mine has the manual little dial knob that clicks on and off as needed....sorry, I cannot help...but I guess there might be hope for less digital solutions. Worked like a charm for 6 years...cheers. |

I use a ranco on my fermentation chamber (chest freezer). I started getting the same error message when I made lagers (50F) but not ales (66F). I switched the controller to celsius mode and it worked fine. If I switched back to farenheit, I got the E2 again. I should email the company but haven't got around to it. |

My Ranco gives an E2 error code also. I'll give the celsius setting a try. |

If indeed the controller works only when set to display degrees Celsius (is this an argument for the superiority of the metric system?  ), it sounds like a bug in the embedded software. Someone should contact Ranco about this. |

I had seen that using the Celsius mode might work. Unfortunately it did not work for me |

Johnson A419s here . . a couple of them for a number of years, and never so much as a hiccup. |
