Can I replace a BAT85 rated at 40V, 1Amp with a 1N5822 rated at 40V,
3Amp?

That should be fine, if there's room for it.

Are these like fuses if the amp rating is higher than the original
specs, it burns up the cicuitry before it blows?
Or will the diode blow at 40V?

Diodes are not generally sized to blow as fuses. They are sized to
carry all the current and voltage that they should ever see under
normal conditions.

OTOH, if yours has blown, you might want to wonder why. This might
just be a random failure, or a poorly choosen OE part, but it's more
likely that something else is wrong downstream. You'll want to find
that something else, and fix it, too.
