Ranco Temp Controller Problem

Hello all,

I have had my heaters hooked to a ranco temp controller for just over a year now. I was doing some work on my stand and needed to unplug the controller from my apex to run the wires somewhere else. I did pay attention and notice that it was reading correctly at 79* before I unplugged it.

After I finished what I was doing and plugged it back in it was reading 113* and wouldn't cut the heaters on when needed. I ended up having to plug the heaters in directly to my apex but am wondering why my ranco screwed up all of a sudden.

Anyone know if the sensor just went bad or something? I can't get ETC to pick up the phone, answer voicemails or emails to help me trouble shoot it. I have been trying for weeks now to get in contact with them.

I don't mind replacing the sensor but if that's not going to fix it is rather not waste the money or time.
 
Well. First start by checking with wiring for the temp sensor..
Maybe you shorted it out or a strand of wire is causing a problem or something..

Is that maybe 113 deg C and around the max limit of the device indicating it thinks the sensor is at the top of its limit? That would indicate a short or other problem too..
