Ok...I just got a 1266 Incubator with automatic turner and Brooder. I paid $150 for both...and I think it was a good deal? However, I know nothing about them and although I have been researching like crazy...I am still confused and have a few questions. First for background...Each unit has a wafer thermostat in the back/middle portion of the incubator and an electronic thermostat model # 3140 110 volt ac/400W near the front of the incubator. They have a fan in the back of the incubator. see pics I found how to set the temperature on the incubator and brooder by first setting the wafer thermostat to 102 F...which I did on both units then setting the electronic thermostat to about 99 to 100 F...which I did on the Incubator but it appears the Brooder's electronic thermostat is broken as I cannot get it to lower the temp to 99-100 F.. So...what heats the incubators? Is it the electronic thermostat or something on the fans....or these porcelain insulators https://www.gqfmfg.com/store/comersus_viewItem.asp?idProduct=115 ? I see these in the back of both the brooder and incubator.. see pics I want to replace the existing thermostats with an electronic thermostat and am thinking something like this http://www.amazon.com/dp/B00F05UI8O...lid=35XFS9S38OYHE&coliid=I3O5TD3HZ8675X&psc=1 . So...as my brooder is no longer heating ... or at least appears to be only controlled by the wafer thermostat? with electronic thermostat broken?...what heats my incubator and brooder? I assume the old broken electronic thermostat is not a heater and could just be replaced with the above electronic one as opposed to spending $85 from GQF to get a replacement non-digital thermostat? https://www.gqfmfg.com/store/comersus_viewItem.asp?idProduct=149 I really do want a digital thermostat..as it would be easier to set and maintain.. I hope this is not confusing...but I don't want to spend a bunch of money for something I don't want... or need. Any suggestions? Thanks!
