In short:<\/strong> a soft crackle is the sound of liquid vaporising and means the coil is working properly. Loud popping, gurgling, and hot droplets landing on your tongue are a different thing entirely \u2014 they mean liquid is sitting somewhere it should not be.<\/p>\n

Normal crackle vs a problem<\/h2>\n\n\n\n\n\n\n\n
Normal<\/th>\nNot normal<\/th>\n<\/tr>\n<\/thead>\n
Soft, even crackle while firing<\/td>\nLoud pops, like oil in a pan<\/td>\n<\/tr>\n

Nothing reaches your mouth<\/td>\nHot droplets on the tongue<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

If nothing lands in your mouth and the sound is even, leave it alone \u2014 that is the coil doing its job.<\/p>\n

1. Flooding \u2014 the usual cause<\/h2>\n

Too much liquid has reached the coil, more than it can turn to vapour. The excess boils violently and spits.<\/p>\n

It happens after overfilling, after leaving the device lying on its side, or after taking it off a plane. The fix takes thirty seconds:<\/p>\n
