A bit frustrated right now because my mash water is now 158 when I was shooting for 152. I actually set the temp for 148 and I was going to ramp up from there but after it hit 148 as soon as I started to bump up the temp the probe readout jumped all around until finally settling on 161. I confirmed the temp with a Thermapen. So while I thought I was heating to 148 it actually went to 161 and now I have to wait for it to cool before I can mash.
Any idea what would cause the PID to jump like that? Should I replace it or look for a wiring issue?
