My last hatch was pretty much nonexistant. Last month, I had trouble with a TH120 incubator holding temperature. On day 15 of incubation, temperature dropped to 92 and did not get any higher. The controls became completely unresponsive, and the light would not come on regardless of the temperature or the adjustment. I transferred the bowl to another TH120 base, where the turner was broken and the thermostat was presumably okay. However, nothing hatched. I purchase a replacement part EC500 from Cutler Supply. I went through a rather painstaking process to replace it and connect all the wires. I plugged in the incubator to run for 12 hours. This morning the temperature was a bit low and I attempted to turn it up. However, the controls did not respond. The light turned off and would not come on regardless of the temperature control or the temperature. I've reported this to Brower, but it's not under warranty anymore, so I'm only hoping for advice. Does anyone have any more ideas? What is wrong besides the thermostat? Or what is wrong that keeps breaking the thermostat? I was hoping to have it ready for eggs within a few days. At this point, I am rather dissapointed with the Brower Incubator, and wished I'd spent the money for the replacement thermostat on a competitor's product instead. I probably do want to switch incubator models, but don't have budget for it right now.
