Yesterday I suffered a minor panic attack cause the temp in the incubator had dropped to 25 degrees C (78 F) when I came home after work..... it looked like the thermostat was off, but it was still 78 degrees (measured with infrared thermometer). So I disconnected it from electricity, reconnected it and the 'on' indicator got on. So I put it back in the water in the incubator, and after a minute it bursted and smoked! So now I have a alternative setting with a heatmat and a tub with water, but this afternoon I'll have to buy me a new thermostat/heating device. Will cost me as much as this second hand incubator including the broken one costed me....
But the alternative set up keeps the eggs on 82 F today, so they'll be fine I think
