Energy Saving Tips for Refrigerator
Temperatures
Don't set refrigerator and freezer temperatures too low. Your unit will work harder than it needs to. The recommended temperatures are 37 to 40 degrees for your refrigerator and 5 degrees for your freezer.
Moisture
Don't allow frost to build up in your freezer. Frost build-up reduces the efficiency of your freezer.
Look for a refrigerator with automatic moisture control. These have been manufactured to prevent moisture accumulation on the cabinet exterior eliminating the need for the addition of a heater.
Make sure your refrigerator doors seal airtight. Cover liquids and wrap foods in your refrigerator. Uncovered foods emit moisture into the refrigerator and make the compressor work harder.
Efficiency
Minimize opening and closing your refrigerator and freezer. Every time you open it, cool air will rush out and be replaced with warm air, causing the refrigerator to run more to stay cool.
Keep it full. Refrigerators and freezers actually operate most efficiently when full, so keep your refrigerator and freezer as full as possible (with bottles of water if nothing else).
Keep condenser coils on the back of your refrigerator and freezer clean.
