How can I safely check if my recovery pass phrase is correct?

It's been over 5 years about since I got the Ledger where I sold a lot of them to help pay for grad school. I have about $380 total on it so it's not the end of the world to lose but.

Back when I thought what if bitcoin goes to a million, I had written them down in a secret order just in case. and while I think I know the order, I'm a bit not sure. I'm a bit worried if the Ledger device stopped working that I want to be sure I have the right recovery phrase.

Is there a safe way to check that my code is right without making it "hot" as they say?

Thank you

edit: also is there a common time frame that ledger devices work for, since it's a device, do they have a shelf life where they start to degrade?
