I'm not an electrician- I don't know the right terminology- I'll try to be clear... I cut off the broken controller from my electric heating blanket. I connected one lead of the blanket to house mains. I connected the other from the blanket to one lead of a five bulb parallel incandescent lighting fixture. I connected the other lead of the fixture to one lead of a basic plug in dimmer switch. I connected the other lead of the dimmer switch to house mains. The blanket doesn't get as hot as I'd like it and it's sluggish to warm up, but it works well and will last longer than the originals which are made to break in a couple years. Is there a simpler way to use a dimmer switch to control an electric heating blanket?
