Although I have only used incubators with fans these last 10 years, I used to have the basic Hovabator, and I consider them a good brand. Was yours brand new? Have you tried calling GQF directly and asking for help? I know how frustrating it is to lose a hatch. The wafers do need replacing every so often (I keep a spare around) but if your incubator was new, that should not be the case. Contact them at sales@gqfmfg.com and ask for help. It doesn't hurt to try! Good luck.

Yes it was new :( My friend and I bought it last fall

I can't speak from experience but, from everything I've read on this site about incubators, leads me to believe that the new Hoverbators and Little Giants are difficult to regulate and are very sensitive to the ambient temperature of the room. You couldn't give me one.

I also suggest contacting GQF directly, or where ever you bought the incubator. I have used the Hover-Bator and have had good results overall. I have hatched many chicks, ducklings, and goslings in one. When I did have a problem. I called GQF and they were friendly, and took care of the problem very fast.
There are "do's and don't" with the stryo incubators. Like any tool, they need to be used within their capabilities. I hope you find the problem issue and get it solved.
