Blenders are handy electrical gadgets that make chopping and mixing food easier--when they work. Otherwise, they are another thing that sits on a shelf waiting for the day you can get around to fixing it. Today is the day!

How Does It Work?

Turn the blender over to access screws holding the baseplate.

A food blender uses a motor to power blades that chop, and grate food. A blade inside a jar is connected to a motor shaft inside the unit. The blade's speed is controlled by varying electric current to the motor using one or more switches. Blenders come in countertop and hand-held models.

Fix-It Tip

When purchasing a blender, look for one with the strongest motor, measured in watts (W). The wattage should be noted on the underside of the unit. A better blender has at least 250W.

What Can Go Wrong?

Because blenders are simple motorized small appliances, the things that can go wrong also are simple. The electrical cord, motor, switches, or fuse may fail. Parts may become loose or worn and seals may leak. (To avoid spills, don't fill the blender jar more than two thirds full when in use.)
