My wife brought home a flat iron, used for straightening hair, from a
woman she works with. It would turn on, but not get hot. I opened it
up and discovered that a resistor (one lead blown off the board) and a
triac (case had a chunk missing) had failed.
Questions:
What would have had to happen to cause this?
What likely failed first? Did the resistor fail, causing the triac to
fail, or vice versa?
The resistor is tiny, about 6mm x 3mm, and the 5 color bands are very
hard to read. My DMM reads 1.2 Mohm. Is the reading from a failed
resistor accurate enough to get a replacement? If you had a resistor
that you couldn't read the color bands on, how would you replace it?
Thanks in advance.
