11 yr old fridge - costco kirkland/whirlpool side by side fridge/freezer. I am going through the house finding inefficient energy consumers and noticed this is suspect. Hooked up the killawatt and indeed the compressor must be turning on (runs at 2.7amps most of the time) almost constantly. Using at least double the power of a new fridge (avg 3.5 kWh/day, 1260 kWh/yr).

The freezer and fridge are appropriate temperatures, and no frost problem in the freezer. I have fridge set to 2 (out of 5) and the freezer to B (middle) setting.

Any ideas? I vacuumed out the bottom condensor coils the best I could, but noticed no change. They don't seem very warm to the touch.
