I have been using my electric brewery for about a year and a half now, and it has been working very smoothly and great. I was brewing a beer this morning and noticed my mash temp kept rising, so I kept adding ice to cool it back down, then it happened again, and again. I got a thermometer out and read the temps to see what was going on. The mash tun was correct, but the hlt was 10* warmer than what the pid was reading. I have not changed any settings (I had written out what they were a while ago and double checked). Anyone ever had this problem before? I am using an rtd sensor on the outflow. I find it's odd that it is 10* on the nose. I did calibrate them a while back and mine were close enough that I didn't need to do any changes. However I did set my hlt to -.6* to account for the heat loss through tubing and pumps. That kept my mlt dead on with what I set my hlt for. My new setting is +9.4 and is now holding correctly. I'd rather not have to buy a new $35 sensor if I don't have to.

That's odd. I'd try checking the wires and make sure nothing is loose.

Did you call auber and see what they have to say?
Pay particular attention to the RTD connections. Weird things can happen when temp probe wires get loose.

Did some more testing while I was still mashing yesterday. I noticed if I plugged into a different sensor it would still need the correction, which meant that it was something with the pid. I opened the case to have a peek inside, heard a few clicks as I did. The pid was getting only an intermittent signal from the sensor. I suspect one of the spade connectors might be loose inside. All seemed to work fine after a jiggle, the temp went back to normal as well! Problem solved case closed, thanks to all for the suggestions.

I have the same issue. Mine is my xlr connector, it is picky, jiggle it and temps go crazy.
