If your freezer has an automatic defroster (frost-free) but does not defrost, return to our troubleshooting guide and look under "Freezer does not defrost automatically".

If your freezer does not have an automatic defrost feature, you will have to defrost it manually. Some freezers have a manual defrost setting on the temperature control or a push button. If your freezer has no defrost feature at all, you can defrost it by unplugging it and placing a defrost heater into the freezer or by unplugging it and leaving the door open.
