Yes, 690 ohms sounds very low. It definitely sounds like there is something wrong there. However, it may be hard to diagnose, because it seems as though something has failed partway– not all the way open or shorted –either of which would make this pretty straightforward. In the absence of any better guidance, and if D12 seems to be working more-or-less correctly, I’d suggest replacing D21, as it seems like that is the likely point of failure.
