Replace cracked glass in vinyl window
I have an older vinyl replacement double hung window. The top sash has a cracked glass pane in it (double-insulated). The home inspector suggested it would be cheaper/easier to just get a replacement sash/glass for the existing window.
I've been so far unsuccessful figuring out what brand of window it is, and if it's easily replaceable - or if I should just replace the whole window.
The lock on the sash says "DACO", and the sticker on the inside says 500V White with what I assume is an order number (F0602990) and the size (28.25" x 57.5").
Any suggestions?

You need a new IGU, this is a common problem. The information you need is the dimensions of the pane.

Ah, thanks... that's the term I was missing in my searches. Seems easy enough to replace the mystical 'Insulated Glass Unit'.

Oh, yeah - we replace about a dozen or so every year in our units and we do the work ourselves.

The thickness of the IGU and the thickness of the two faced tape that was originally used are critical. If you dont feel comfortable DIY take the sash out and drop it off at any commercial glass house. Will take a week or two to get it back.

The guys on the forum walked me through a replacement on a fixed IGU a few weeks ago and a double hung is easier due to small size.
One side of the glass has trim pieces that are pressed in, many videos show how to remove. Once they are out you can get the size and thickness.
I haven't taken a double hung apart so assume it has the same tape as the fixed glass. That was the hardest part getting all the old tape off but once done reassembly is quick!
The cost of the IGU alone was less than 1/2 of them replacing so a good return on DIY project.
