2017 increased refrigerator and in-wall oven efficiency

Replacement fridge

Old fridge

Fridge set to 3 (5 oC); freezer set to A (-14 oC)

Power demand after reaching target temperatures:

33W closed

98W right and left open

73 left (freezer) closed; right (fridge) open

57 left open; right closed

R+L = 65; R=~40; L=~24 (probably mostly the wattage of the light bulbs)

Power demand with compressor at work:


330 Compressor starts

300 >30s

298 >60s

292 >180s

290-95 >10min (steady state while working to reach target temperatures)

Watt-up measurements of old fridge:

10.54 kWhr for 60:27 hr

= 174 W

Watt-up measurements of new fridge:

Fridge set to 3 oC; deli drawer set to 3 oC; freezer set to -19 oC (changed to -15 oC on 11/16/17)

5.62 kWhr for 80:15 hr

= 70 W

~ 40% of old load

New oven
