I was recently given a hova-bator genesis 1588 with a fan and auto turner. Everything appears to be in working order except the temp setting. It is the style with the dip switches on the bottom of the cover to control the temp. On the high setting of 8 I can only get the temp up to 98f. Does anyone have any experience with this incubator with the temp control setting via dip switches. Maybe I am doing something wrong. Or is 98f hot enough when using the fan for a successful hatch?
