I have a brand new hovabator 1602n with egg turner & fan. I'm on day seven. I candled yesterday and since then, I can't get my temp back up to 99.5. It has been consistently 99.5 up until this point. Outside temps and room temperatures are the same as they have been. I've adjusted the thermostat now 3 times and it stays at 98.8. I know people says that a little adjustment goes a long way... Well, doesn't appear to be the case here. I'm so frustrated. It would appear, I have a wafer thermostat problem. Any suggestions?
