I have brewed around 30 batches with my electric setup (thanks for all the help found here).
I had some weird small temp fluctuations on the last batch but didn't worry about it.
Today I brewed and with the PID set at 152 degrees the temp started at 80 (normal for Texas) and as it was going up it just went berserk. I showed -6, 165, 343, etc. It just kept bouncing around and apparently the PID told the element to stay on. By the time I retrieved my other thermometer and checked it the temp was 155 but the PID showed 165 and pretty much stayed at 165 even though my Thermopen showed 155 degrees. I ended up shutting the power off to the PID and the element.
After turning it back on to get a boil going, it seemed to work just fine. But that makes 2 batches with these temp swings and unreliable temp readings.
I checked all the connections to the temp probe and in my control panel and they are all sound.
So how to I troubleshoot this? Do I just order a new cable, and temp probe and swap them out one at a time? Could it be the PID?
Thanks in advance.
