How Many Watts does a Refrigerator Use

Report as

It is all depending on the size of the refrigerator. The typical refrigerator uses about 300-400 watts. You have to determine the size you need and then check the wattage.

The wattage of a refrigerator varies depending on the size of the refrigerator, how clean the coils are, and room temperature. Refrigerators have become more inexpensive to operate due to energy saving techniques that have been developed over the last several years, however the refrigerator still ranks as the topmost energy consuming appliances in the home. Average wattage for a 18 cubic foot refrigerator is about 484 kwh/year.

484 kwh * 1000 w/kw / (365 days/yr * 24 hr/day) = 55.25 watts

My 2000 GE 25 cu ft side-by-side is a pig (1305Khw/yr). 149W average, 325W running (says KillAWatt meter). A new \$1250 Sears 25 cu ft is 528 kwh/year (60W), so I'd save 777kwh/yr * \$0.16/kwh (tier 3) = \$123/yr. It would take 10 years to pay it off, which is about how long they last nowadays. I've extended the life of the GE by replacing the starter relay myself twice.
The GE uses 109 of my total 470 kwh/month (23%).
