Report "I have the Hobart 250 model. I have gotten much use from it. Recently I was using it, I wouldnt say over using or abusing either. I put it up for the day, and when I went to use it the next, it simply just wont come on. No power light, no fan nothing. I checked power to the switch, good, from the switch out, good, and going to the board, good. I read about thermal fuses, although cant seem to find one as is described on other posts. Any help to the problem is great, thanks"
