Defrosting Manual Defrost Refrigerators
There are two types of refrigerators that require routine manual defrosting. They are the Manual Defrost type that will require defrosting every 3 to 6 weeks under normal conditions, and the Two Cabinet Design that will only require defrosting only in the freezer section normally about once every six months.
Generally, defrosting should be done only when necessary and should be done as soon as necessary. A build up of frost around the freezer box will act as an insulator resulting in warmer temperatures. The amount of time duration in between defrosts varies as to how often the door is opened, and the relative humidity in your kitchen. The frost that accumulates on the freezer box comes from the moisture out of the air that enters the cabinet when you open the door, and also from moisture out of unwrapped food. If you have a frost accumulation all around the freezer box of more than one inch thick, it's time to defrost.
Step one:
Turn off the control or unplug the refrigerator. Remove the frozen food to an insulated cooler or deep freeze.
Step two:
Set a pot with about two quarts or liters of boiling water inside the freezer compartment. Close the doors.
Step three:
Wait about 1/2 hour. If frost is still present on the sides of the freezer compartment repeat step two. Remove the pot of water and any pieces of frost left inside the freezer. Empty the removable tray under the freezer box.
Step four:
Dry off the freezer box surfaces with an absorbent cloth. Replace frozen food and turn the control back on or plug in the refrigerator.
Hints:
* Hand held hair dryers work very well on large pieces of frost that are hard to remove.
* Never use a sharp metal tool to assist in removing or picking off frost, you can easily puncture your evaporator. If you need to use anything, use a wooden or plastic egg turner.
* Never plug in an electric kettle that is placed inside the refrigerator. The steam that results is hot enough to melt the thermo-plastic components inside of the refrigerator.
