Bought one of these $5-8 Chinese made hair dryers from Amazon just to take to bits. They have no UL or NRTL listing, heck they don't even list the voltage or wattage on the casing.
First thing first: When I plugged it did not turn on. Instead it started to smell like burning rubber and acetone. The kind you can taste. The heating elements just glowing cherry red getting only whiter to which I promptly unplugged it.
Upon opening I discovered two things-
1st, the thing has no high limit and no thermal fuse despite holes being punched in the mica for these exact components. Instead the "return" nichrome wire just snakes through the holes:
2nd- and the interesting part... the leads for the motor are shorted to the metal case of said motor on both sides making it inoperative.
