I just picked up this on Saturday, The lady said it had a electrical problem. I look at the stove, it had a burn resistor and was missing the fuse on the control board. I had a old whitfield board and removed this resister and fuse. The vacuum switch is bad. By passed the vac switch, installed new resister and fuse, the stove works great. I picked up the stove for free, I would like to sell it , but worry about the stove going bad and have someone coming back with problems. What's this stone worth...
