Is $1,900 to replace a pool salt cell a fair price?

I recently hired a new pool company for monthly maintenance. As part of this service, they performed a full diagnostic of my pool system and informed me that my salt cell was not functional and needed to be replaced. The existing salt water system was installed about 2-2.5 years ago, which seems abnormal given that most information online suggests a typical lifespan of about 5 years. I'm questioning if this quote is in line with typical repairs and if there's a way for me to verify the salt cell's functionality without getting another quote. I've also had companies servicing the pool weekly for over a year.
