Wafer thermostat in little giant

[Th55]

Wondering if anyone has ever replaced the little giant knob thermostat with a wafer type as in the Hovabator?
My concern is with the difference in wattage of the heating element, I would presume since the LG has a 40 Watt heating element it most likely would swing the temperature much more that it does in the Hova Bator with the 25 watt element.

Is there a reason you want to change it out? I really don't care much for the waffer thermostats personaly.

I’ve read a lot that the LG (knob type) was notorious for failing and cooking hatch. For redundancy I had installed a brooder temp controller on the incubator with the off set point at 103 so if it did fail “ON” I might could save the hatch. Early in the incubation the thermostat did just that. So for 4-6 hours it swung temp from a max of 105-97.
It is a used bater but has worked fine the last 2 hatches. I had a second LG incubator set up, stable & running as I have some eggs set to arrive in a couple days, so swapped over the tops and it has been steady since.

So am looking to find another type /style that might be more reliable. I know being mechanical the wafer is not as consistent but was looking more for a dependable option.

Played with another temp controller on hand but it’s minimum differential is 2deg. It’s over/undershoot is too much for me.

You'll find lots of food for thought in the first page of the following thread.

I don't think the difference in wattage would have much impact on its effectiveness.
I've had lots of embryos executed in a LG. I refuse to use one unless absolutely necessary and then only for a day or two.
Check out a stc1000. It is quite reliable.
Don't get overwhelmed by the wiring diagram in the following link. It is for both heating and cooling for a brewing system.
You don't need all that to wire the LG.

Another idea would be a 12 or 24 volt dc system. That way you could run it if you have a power outage.

That way you'll also make it a forced air unit.

Wow, thanks that’s a powerful thread. Can’t believe a ain’t run across it before.

I actually bought that stc 1000 and might be what I go with. Was trying to clean it up and not have it it looking like a time traveling Delorean

I really do like that 12 volt controller/heater/fan option you showed as we do have semi regular power outages. It would be easy to set up.

Thanks again
