DRAIN PAN DEFROST

The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer: For every 6, 8, 10, 12 or 24 hours of compressor operation it turns on a defrost heater for 15 minutes to half an hour.

A defrost thermostat opens the heater circuit when the evaporator temperature rises above a preset temperature, 40°F (5°C) or more, thereby preventing excessive heating of the freezer compartment. The defrost timer is such that either the compressor or the defrost heater is on, but not both at the same time.

A drain is a channel, conduit, or pipe designed to carry away or channel superflous liquids for disposal or reclamation. A drain assembly is one or more components of a larger mechanism that facilitates as a drain. A drain assembly component may be a pipe, stopper, pan, basket, valve, filter, plug, hose etc.

A drip pan or drain pan is a container for catching material such as water or grease that drips from above (as from the burners of a gas range or condensation from an evaporator).  It is usually a shallow rectangular metal or plastic pan used especially for baking and roasting, frying, and water containment and may be connected to a drain or drain pipe.
