Right next to it on the list
A rank or two either side of the THOR KITCHEN RF3621CTD99: THOR KITCHEN RF3621CTD00 ($101/yr, 539 kWh/yr), then THOR KITCHEN RF3621CTDW ($101/yr, 539 kWh/yr).
Within the THOR KITCHEN lineup
Ranked 17 of THOR KITCHEN's 23 certified refrigerators, this sits between the RBC24SSD ($50/yr, the brand's cheapest) and the TRF3628FFD ($140/yr, its priciest).
What this adds up to over time
NAHB's Study of Life Expectancy of Home Components puts a typical refrigerator's service life at 13 years; run the THOR KITCHEN RF3621CTD99 that long and it costs about $1,317 in electricity, on top of whatever it cost to buy.
Is it worth replacing?
The THOR KITCHEN RF3621CTD99 runs above its category average. If the refrigerator you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $101/year every year.

If you're keeping it
The THOR KITCHEN RF3621CTD99 already costs $101/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
