Frost Free Vs. Manual Freezer

When it's time to consider buying a stand-alone freezer, your primary decision is whether to opt for a frost free or manual defrost model. The basic difference between the two is how they handle ice build-up. A frost free model will automatically thaw the ice as it accumulates, while the manual freezer must be cleaned out periodically by hand.

Frost Buildup

Opening and closing a freezer can cause water vapor which, when it hits the coils, turns into ice. Over time, the ice can become quite thick, enough to noticeably deplete your freezer's storage space.

Frost Free

A frost free freezer has a built in defrost cycle that keeps ice from building up inside the appliance. Every 6 to 24 hours, a heating coil comes on and raises the temperature just enough to melt the ice.

Manual Defrost

This type of freezer is a little more work. Every six months or so, pull all the food out, leave the door open and let the ice buildup melt.

Warning

While frost free freezers are handy, there is the drawback of the increased risk of freezer burn to your food, caused by the frequent raising and lowering of the internal temperature.

Considerations

Manual freezers are normally quieter and use less energy but, obviously, require some effort periodically.
