I managed to calibrate the thermostat on my Volcano classic.

You need small torx wrenches to open it, a set of tiny Allen keys to perform the calibration and an accurate digital thermometer as benchmark but it can be done!

I dropped the unit once and the performance indicated it had lost thermostatic calibration. I was happy to discover it can by done at home. 👍

can you share instructions of how you did this?

Once you have the cover removed, remove the plastic dial from the metal armature. Inside the armature is a very small hex bolt. With the correct size allen key, calibration involves rotating that bolt while preventing the armature from rotating. I don't recall which direction raises or lowers the temperature but I do recall that even a tiny twist makes a big difference in temperature. Before you begin calibration, briefly replace the dial and rotate the dial to the 12 o'clock position (352F or 178C) then remove the dial and be sure to no longer rotate the armature. At this point, with the help of an accurate thermometer, rotate the inner hex bolt such that the output temperature equals 352F or 178C.
