Question if I could. Thanks for the advice on the that thermocoupler. When I pushed it through the fiber insulation a piece of the fiber face on the inner side came off(approx 0.5 cm). The probe seems a little loose to me. Does that matter? If so is there anything I can do to fill that gap to make it a snug fit?Yes you remove the bimetal thermometer and that K type thermocoupler goes in the same hole. Your looking for the K type 6inch 2k degree one.. I got mine from thermoworks
