Right next to it on the list

Same brand, different models
Ranked 5 of mbm's 6 certified refrigerators, this sits between the MRF7B ($62/yr, the brand's cheapest) and the MRN14W ($62/yr, its priciest).
Cost over its typical lifespan
13 years is NAHB's typical service life for this category; at $62/year, the mbm MRN14S adds up to about $811 in electricity over that span.
Weighing a replacement
Efficient as certified refrigerators go, $62/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
At $62/year just to run, a refrigerator is worth protecting against an unplanned repair bill on top of that.
