A newly crafted Industrial Neon Furnace has incorrect logistics settings:

The Energy and Support settings are on None, meaning it gets no power by default.

The Items setting is on Input/Output, which is a setting that should not be possible, since you can not set them into that mode with a Logistics Editor

do you recall your crafting ingredients, as the nbt data from there is passed on.

Well, one of the ingredients is an Industrial Furnace, which can not send or recieve power and has item logistics set to Input/Output by default.

Perhaps that is indeed the reason.

This is very lickely the cause.
