Hi everyone, new to the forums and didn’t see a thread with the issue I’m experiencing. It may be a bit of a read so I do apologize in advance.

My wife’s friend, who is an elementary school teacher is doing an embryology project for her class. The school has bought a Brinsea Mini II Eco incubator and she asked my wife to set it up.

Last night I had set up and stabilized the incubator temperature to the 99.5 degrees F as suggested for chickens (red light began flashing instead of constantly on), but it drastically fell overnight to 85.5 F with the light constantly on again.

According to the searches I’ve preformed, Brinsea says their incubators have a built-in cooldown period of anywhere between 30 to 340 minutes.
They don’t specify which models the automatic cooldown periods are for, so I would assume this means all of their incubators have it.

The problem I’m experiencing is the Mini II Eco incubator the school bought doesn’t seem to want to come out of the cooldown. It was been almost five hours at a constant temp of 85.5 to 86.5 degrees.

I have found other suggestions that say the room temperature may be the reason. The room has a running temp of 74 degrees and the incubator is not near the air register, so I don’t believe this is the issue as it is within the recommended range.

Has anyone else had this issue?

Hi, welcome to the forum! Glad you joined!

I agree. The better you describe your issue the more likely we are to be able to help. It is really hard to give helpful advice if we don't have a clue what you are talking about. I have no problem reading a long post giving details. You never know what detail might be important.
 
It is not due to room temperature. That is close to perfect. My suggestion is to contact Brinsea and talk to them. They designed the incubator, they should know how to troubleshoot it.

I'm not familiar with that incubator so I can't help.

Well darn. Will try to contact Brinsea. We have another incubator coming, already bought the fertilized eggs and the brood box for the chicks, but the class this was intended for may not be able to do it this year. Thank you for the help though.
