After researching a bit more.... The temperature probe supplied with the AKO-13120 temp controller is an NTC thermistor (AKO part AKO-14901 and has a temp range from -50C to 100C). There's a small circuit board with a resistor that was potted in epoxy. The epoxy and insulation on the wiring have been cooked to the point of being brittle. The wires were shorting along the thermowell and causing erratic temps on the controller.
So, I tried cutting back the wiring and resoldering to the small circuit board.... I thought I had it for a moment.... but, I'm still getting the E1 error code. I looked closer at the circuit board... looks like the small site where one of the leads was supposed to be soldered has delaminated from the board. So... I tried Barry's method of twisting and soldering.... that doesn't work in my situation, unfortunately. Still getting an E1 error code.... I'm assuming that the temp controller is fine and all I need is a new NTC thermistor (temp probe). Is there a way to troubleshoot this any further??? Assuming the controller is okay, I'm looking to get a temp probe only. After perusing AKO's (non-user friendly) website, I think they likely outsource the thermistors, and they don't give a lot of specs on it so I don't really know what to look for in a replacement thermistor. Anyone have a suggestion???? Money's tight for us... I'm out of work... I'd rather not have to buy a controller just to get a part that should cost less than a dollar..... Anyone have a suggestion???? Thanks, Tonedeef -- You received this message because you are subscribed to the Google Groups "Brewtus" group. To post to this group, send email to [email protected].
