I have an old Hovabator 1602N that was my father in laws. It's been in storage for years and we decided to to get it up and running again. We've had it on for a couple of days and cannot get the temperature to stabilize Went to bed and it was reading 100 hubby said his am it was at 95. Via a Brinsea spot check. So I need some advice! I've never hatched before but want to maximize my hatch rate. Should I buy a new wafer and possibly a fan, or just upgrade and go with a new genesis? Or are there some other brands/models out there I should consider? TIA!
