I just borrowed a little giant incubator. Found out it was a reall old one with the snap thermostat. the good thing about it is it has the turner. I can figure out the thermostat at all. I don't understand the instructions. It says: Turn adjusting screw clockwise until it bring the wafer in contact with the micro switch(?) and you hear a light click. You will notice the pilot light goes out when you hear this click. Now turn the adjustment screw count-clockwise 6 complete turns. The indicator light and heater element are now turned on and the wafer has room to expand as the incubator heats up. The red indicator light will always be on when the heater element turns off. That statement right there seems totally wrong to me. I feel it should be the other way around. Anyway nothing I do turns off the indicator light. I dont hear the click it wants me to hear and the wing nut gets in the way all the time. I was excited to get this one but it seems to be more of a problem than my home made one. Has anyone here used one of these and can give me some information a little clearer. I don't know if the wafer is supposed to go all the way down and touch the switch thing or not. I can't tell if it does. The light never goes out either. It all sees totally backwards to me. Help!
