Andersen Balance replacement

Yes, it would be a good idea to replace both at the same time. If one balance failed, it's likely that the other isn't far behind.

I would be happy to offer a suggestion for a replacement, if you'd like. Please remove the balance from the window and tell me what stamps are printed on the surface of the box. It may be even better if you take pictures of the stamps. Sometimes seeing how the numbers are printed is just as important as the numbers themselves.

Hmmm... can you double check the BJ27 stamp? I think it might be 8J27, instead. If so, I recommend our 24-837. This can replace balance boxes with a stamp of 8J27.

Well, a 24-531 can replace balance boxes stamped with 519, certainly, but not 527. At this point, it may be best if we see a few pictures of the stamps for both balances. Like I said above, sometimes seeing how the numbers are printed is just as important. There are some subtle differences between numbers that we can catch, and that will let us know right away which number is the key number. Otherwise, we're dealing with a jumble of characters and it can be a little confusing.

Thank you! Looks like 519 is stamped on both balances. Therefore, I recommend our 24-531.

That is weird! This balance has both the 5 27 stamp and the 8 27 stamp. I'm a little confused why they did that. I think the best t hing to do now is to give us the size of the visible glass for that window. That is the only other solution I can think of.

Thank you. In that case, I think the 24-531 would be best for you. I still cannot guarantee it will work, but it is the closest match I could determine based on this information.
