OLD Hovabators are AWESOME when they get right. and parts are not expensive.
sounds like your wafer thermostat is loose tighten up the wafer and start by getting the set points right. check all the connections too to make sure nothing is loose from the years passing by.
I have 4 different incubators from the old hovabator I added fan and turner too.
the brand new this year little giant I did the same thing too
a homemade job out of a fish shipping crate they throw away at pet stores.
and a cabinet 3 tray gqf 1270 with all the bells and whistles and a 5 gallon water capacity.
I use the hovabator the most. every hatch this year has spent 18 days in it.
Buy a new one if you want to. but get a fan and an egg turner in it.
fix the old one and use it for the last three days.
I'll sure be glad to help you trouble shoot it and get it holding a steady temp.
If your close enough bring it by or send it to me and I'll be glad to fix it.
I'll even trade the brand new LG to you as I hate it. it hatches a good chick. and my lowest hatch rate of the year has been 87 % and I've been through 7 hatches so far this year.
I've found it dosen't make any difference which incubator I use. the hatch rates are the same.
Don't hesitate to contact me if you want to. I'm always willing to help a brother out.
Hello, i have an OLD hova bator still air incubator from prob the 80's. I seem to have alot of problems with it. It took 4 days to reach temp then held for 2 weeks then crept up to 114 deg. I cant take it, i am going to get a new one. I am looking to spent no more than $140 But i would like the bells and whistles. Does anyone have the Little Giant or the Farm inovators Professional Circulated Air Incubator with Egg Turner - 4200? I see the farm inov with everything for about $137. Any info would be greatly appriciated, thank you
