Hi, i am trying to repair dry herb vaporizer for  my friend. I suspect its heating element is faulty as It works fine when element is disconnected and didn't work when its connected.
I tried to measure resistance between its terminals and it shows 0 ohms.
Is there any other way to test it?
Element is connected to drain terminal of p cahnnel mosfet and element, drain side of mosfet are shorted to ground.
james_s:
What voltage does it run from? If it's low voltage then it may read zero ohms on a multimeter that doesn't have a low ohms range. A heating element is nothing more than a resistor, the typical failure mode is they burn out and go open circuit. What do you mean by "doesn't work"? Does it blow the fuse? Shut off?
manubali:
It runs with single 18650 battery around 3.7 volts.
It shuts off after few seconds when power button is pressed.
It was dropped and it stopped
DTJ:
A dry herb vaporizer running of a 18650?
Is it like an electronic bong?
james_s:
For such a low voltage I would expect the heating element resistance to read close to zero. Are you sure it's not just a dead battery? Is the charging circuit actually charging it?
