Is it worth replacing?
The Thermador T18ID900LP is already efficient for its category at $80/year. If you're shopping and comparing options, this is roughly what a well-chosen new freezer costs to run.
Worth comparing a few current certified models before deciding.
Protecting what you have
At $80/year just to run, a freezer is worth protecting against an unplanned repair bill on top of that.
