Can I use only one of the pair from my AX6600?

I've enjoyed my AX6600 since Dec 2021 with no issues until yesterday when the main router failed. It just dropped out and refuses to power up. It's NOT the power adapter. I traded the adapter from the other unit which works fine but, the main still doesn't power up. 

My question is: Can I use the other unit as my main router in place of the one that failed?
