Do you remove the chamber with the magnet to cool down? The cooldown click happens fairly quickly (10 sec or so) when removed with a magnet and left outside of the oven, the click sound is dampened by the magnet so harder to hear but again cools off fairly quickly.Today i combusted for the first time with the ronx torch. Maybe i was too fast, i should probably consciously hear the cool down click. Or i got greedy because i wanted a second heat cycle. But then there was no click and i realized it too late.
Cleaning after combusting is quite a chore and the smell still lingers in all parts of im sensitive to it, the condenser had residue/black stuff and didnt change to clean steel colour again afterwards.
I like to take a qtip after cleaning as i find it helps to show where there is still some dirty parts, i find the condensor is the dirtiest, try drying/cleaning with a qtip one user said it helped with the combustion taste afterwards
