The proper temperature range is about 36 degrees Fahrenheit for the fridge between 0 and 5 degrees for the freezer.
Buying a new refrigerator may dramatically reduce your energy bill.
Clean the coils with a vacuum or duster every six months to improve efficiency and reduce operating costs.
During a power outage a fridge will stay cold for about 8 hours and a freezer will stay cold for about 48 hours. Don't open the door unless absolutely necessary.
Regularly defrost your manual defrost freezer and never chip away the frost.
A full fridge is more efficient than a half empty one, but don't overfill it either.
Do remove the door of a refrigerator or freezer in storage or prop the door open so that a child cannot close the door.
Do keep your refrigerator upright during moving and storage.
Do wait 24 hours after moving a refrigerator before plugging it in.
Keep at least two inches or air space behind your refrigerator and six inches above it.
Don't overfill your refrigerator or it won't cool as well.
Don't chip away the frost in manual defrost freezers.
Don't store your refrigerator unplugged for extended periods of time. Some units require continuous use to ensure proper lubrication of the compressor. If possible, plug in the refrigerator once every few months and
let it run for a couple hours.
Don't tip the refrigerator onto it's side because oil from the compressor can run up into the filter/dryer and get trapped.
