Fueled stoves do not require components to build and thus should not require components to repair.
solutions:
Make fueled stoves immune to breaking
or
Make it so that you need some steel to repair it
The point of a breakdown is that it specifically requires components to fix.
I agree that it shouldn't breakdown.
