Weighing a replacement
Efficient as certified freezers go, $66/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
The Liebherr SIF5181 already costs $66/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
