I have a Durrmaid extractor, it was the orgional one, the 1500 model I believe, when I got it several years ago, it was in the middle of winter, the unit had frozen with water in the lines and a fitting broke before I ever got the chance to use it. I finally got the parts from Durrmaid and replaced them and it worked great for a while. It started flipping the breakers when i would use the heater and blowing fuses in the unit itself... last time I used it a couple of years ago, the wiring looked like it had gotten hot so, I decided I was not going to fool with it anymore, it's sitting in my attic... I bought a Mytee Spyder and love it! It's expensive but it's very dependable. The Durrmaid could probaly have the wiring replaced and be okay or just not use the heater. I'd make someone a good deal on it if they were interested...
