I have an old manual Skutt 181 that I recently replaced both switches on. I've done 4 bisque firings and 3 cone 6 glaze firings so far. The last glaze firing took about an hour longer than usual which I didn't think would be that big of a deal. Well I just attempted a 4th glaze firing yesterday and it hit the 10.5 hour mark and still wasn't course to dropping the lever (it took 8 hours for the first two). It also wasn't making any humming noises like it usually does when it's initially turned on so I turned it off the night and left it for the morning. Opened it up and my glazes didn't even get to a liquid state. Looks just like how I applied it on the pots but the kiln did get fairly hot when it ran. I messed with the switches to see if they would flick on and the medium & high settings on the top one didn't do anything. Cracked open the box and the switch is already burnt. Anyone have any clue what would cause it to burn out already? It sounded like the person who had it before me didn't have any problems with the kiln and had recently gotten maintenance done on it. Almost looks like new besides the two fried switches that it came with.
