## Old refrigerator = high power consumption?

I have a General Electric refrigerator model #TBF16SJB. I think this thing came with the condo when it was built... 1986. I've been wondering if this is the source of my very high electric bill (at least I think it's very high...). I can't find any info on this model, but on the fridge it says that it's 110 volts and 6.5 amps. So, I calculated the wattage to be 715 Watts. Then, I used this formula to convert to kWh for the year:

(715 Watts × 24 hours/day × 365 days/year) ÷ 1000 = 6,263 kWh

That seems like an incredibly high number. I know the number should be less than that since the fridge probably cycles or something. However, is it likely that this fridge is still the source of my high electric bill or is the math just way off?

Probably adds \$100.00 a year to the bill ( my guess ) and yes your figures seem way too high.

The Energy Star site didn't have my exact model listed, but if I left the B off at the end, I get a model with 1,450 kWh. So, I guess that's a start with getting my electric bill down.... Thanks.

That -sounds- more like an accurate number.

You can get them via internet sites or if you have a harbor freight near you they have them for about \$30. http://www.harborfreight.com/cpi/cta...emnumber=93519
