I broke a bandsaw blade today, a big bang (no new life in THIS universe)
and the blade was broken. Looks like stress due to the dulling blade
cutting through several logs and perhaps a twist from when the piece moved
on the sled caused the failure.
My question is this: Is there anything I should watch out for when I put
another blade on? The top wheel got stuck on the sheet metal up top, but a
gentle whack with a mallet solved that issue.

This is probably a good excuse to do a tune-up on the saw... check for
co-planar wheels, check the blocks or bearings, tires, etc.

The quick answer is "use a straight edge".
Snag a copy of Duginske's "Bandsaw Handbook"... It's a good resource.

It's a 14" Jet. Everything seemed ok, but that was only during a quick
onceover trying to figure out how to get the top wheel free again. I'll
have to take a closer look at it.

I was planning on changing the tires anyway, so maybe I'll delay putting
a blade on until the new ones get here. One of them moved on me a couple
days ago as I was putting a different blade on, so I figured it was time
to replace them.
This bandsaw has taught me a lot about bandsaws, but it sure does gobble
up the parts...

Wait, you're supposed to rotate them every 3000 miles?! I thought I was
supposed to do that soon before and during each use. No wonder they need
to be changed!

Bandsaw tires are more like drag slicks... How can you tell with those?
(Not the bandsaw tires.)

You take the table off and anything that restricts putting a level or
straight edge against the wheels.
Both wheels are co-planar when they touch the wheels at 4 points.
So first start with the very top and bottom of the wheels stick a
straight edge/level across them. Then move out to 2 other points on each
side of center. It should still touch at 4 points. If not adjust ..
On my delta w/riser block I had to remove the pins in the riser block.
Delta had no idea how to drill the block or the frame so the whole thing
was twisted. Do what you have to to get it in line. Once you do the
cutting performance is greatly enhanced.

Yes, make sure the blades teeth point down. (DAMHIKT).

Out of curiousity how do you check for co-planarity of the wheels? My
bandsaw is fairly new, but I'm curious how it's done.

In either case, when there is more of the tire on the ground than on the
wheel it's time to change them...
It is item # 10405 improved delta 14" tracking arm...
There are catalogs on line from various sources. I wish Iturra would put
his catalog online.

Don't forget to inflate the tires to the proper pressure. :)

My credo has been "To really learn about something bust it and then fix it!"
I took the opportunity to go over my whole bandsaw and tweak it after the
tire broke. It worked much better afterwards with the tweaking, new tire and
new blade.... I had been running it nearly non-stop for a couple-three days
so the improvement was very noticeable.

I'd check the tires for cuts....
A few weeks back I had a tire break while doing a lot of resawing of large
pine boards. I didn't even notice as the saw kept cutting just fine as the
wheel itself is crowned. It wasn't until I was cleaning up and found the
broken tire laying in the bottom of the saw that I knew the tire broke. I
thought that was really weird! It was one of the tight fitting, non-rubber
tires and it appears to have broken at the joint as it was a perfectly
straight break.

If this is a delta 14" take a look at the piece that hung up.
It's prone to bending at least according to Iturra... He has a new
better piece. If mine ever goes I'll get his... since my post doesn't
track straight up and down and his somehow remedies that.
