I just finished my freezer build. I was seasoning it tonight and and had everything going great and all of a sudden my PID box started smoking. I got it unpugged as fast as possible and took the top off and my solid state relay was toast. Nothing left at all. It had been running for about an hour and a half and was holding steady at about 245 -250 and all of a sudden it just burned up on me. I followed Smokednarwals wiring diagram and I don't know what happened it just when't up in flames. It looks like everything else is OK but it is going to have to take another solid state relay because the one i have is no longer with us, What the Hell did I do wrong??????
