    Dismayed by the fact that all my electric blankets seem to fail after a
    few years, I took one apart.
    the failure mode seems to be degradation in the "heat tape" that
    snakes thru the blanket.
    But there's also a gizmo that looks like a 3-element neon bulb
    that's in series with a 1.5 ohm resistor across the line.
    Only thing I can imagine it does is shunt line transients????

    nope, it's inside the power connector box at the foot of the blanket.
