Before installing the new drawer in your refrigerator make sure the new drawer is the proper replacement part for your model refrigerator.
Check all of the drawer slide rails/glides in the refrigerator to make sure that they are intact and are not broken or have become loose from the refrigerator interior wall. If they have become loose you will need to tighten them. Make sure they are secured before the new refrigerator drawer is installed. If broken, they will need to be replaced.
Make certain the slide rails or glides are cleared of all foreign objects such as food, sticky substances such as jellies, syrup etc. Removing this might require warm water and scrubbing the groves or slots out with a soft scrub brush.
Once you have made sure the refrigerator drawer slide rails/glides are not damaged and are cleaned and secured or fastened correctly, you can proceed to install the new refrigerator drawer. Go ahead and give the new drawer a few test runs pulling/pushing it in and out a few times before loading it with food.
There are many different kinds of drawers/bins in a refrigerator. Some are humidity controlled to keep meat, fruits and vegetables fresh. Some even have a selector knob to control temperature.
Plastic refrigerator drawers can be clear, transparent, smoky grey or white. They are also called bin, meat pan, vegetable, crisper or snack drawer.
If your plastic drawer has a crack or chip in it you might try to repair it with duct tape, glue gun, epoxy, melting the plastic or by drilling holes and riveting it back together. Eventually your repair job will fail. Doing the above repair is just a temporary fix and it is very unsightly and unsanitary.
The refrigerator storage bins, also known as drawers get used and abused. They can break from being overloaded and stuffed full of food. Also, they can be broken when items are removed or by simply trying to clean all of the old fridge goo and gunk from them.
Children love to pull them out and use for a stepping stool to reach items that are out of reach in the fridge.
If you have a drawer/bin which has been damaged, it is best to simply replace it with a new one.
