Brinsea 56 EX screws seized up

[ZielonyKurnik]

I had this exact problem and decided to lightly lubricate the screws at last cleaning. As a consequence, apparently I over-tightened them. When removing or re-installing the screws after cleaning this year, two housings cracked.

See my post just uploaded reviewing the incubator and criticizing the need to remove tiny screws to clean.

Since I hatch in pedigree baskets or bags, however, I wonder if I can remove the inner liner without consequence. It seems to exist to keep chicks away from the fan and heating elements.

the inner lid helps with the air flow beside keeping the chicks away from the parts. it also old the turning motor in place
