Kevin, I noticed you have alot of info about revamping a Hatchrite. One was given to me, a large one with six drawers. Initial power up, shows temp and humidity digital displays are working but not the senser I think. The fans, lights, rollers all come on, but the heaters do not. I don't know anything about how to tell if components are working via circuit boars. I m sure it is something simple, but I don't know. It is 10 years old and was used for one season for emu eggs and has been sitting unplugged in a hatch room ever since. It looks like brand new and there is no corrosion or anything on circuits or connectors. Got any ideas?
