Most refrigerators sold in recent years are automatic defrosting or frost-free. The refrigeration system is basically the same its in a standard refrigerator. The advantages of automatic defrosting systems are gained primarily through the refrigerator control system and the placement or refrigeration system components. Frost less refrigerator types also add an air-circulation system. The early refrigerator automatic defrost system was, for all practical purposes’, a basic system utilizing a single evaporator with a heating clement clamped to the evaporator. A refrigerator timer was connected in series with the element and the refrigerator compressor.

At predetermined intervals it interrupted the circuit to the refrigerator compressor and turned on the heater. This, of course, raised temperatures in and around the refrigerator evaporator to a level somewhat above freezing, causing the freezer condensate to melt and run into it trough where it was collected and carried away to a pan located under the refrigerator compartment at the bottom of the refrigerator. In this coil the pan, heat from the refrigerator condenser (or in some cases, from a low wattage electrical heater) caused the water to be evaporated into the room air.

Refrigerator manufacturers employ various methods of timing the interval of this defrost cycle. Many refrigerators use twenty-four-hour timers. These can be identified by the “day-night” markings on their dials. These refrigerator timers initiate the defrost cycle during the wee hours of the morning (usually around 2:30 A.M.), a time when the refrigerator would not likely be in use. If a twelve-hour timer is used, it will defrost twice each day: usually at 2:30 P.M. and again at 2:30 A.M. Some refrigerator manufacturers connected the timer motor to the thermostat so that it ran during the same periods that the compressor was operating. The defrost cycle theft occurred after a certain period of elapsed running time of the refrigerator compressor. Still another method was to connect the timer motor in the circuit with the door switch so that the timer motor ran during the periods that the door was open and the interior light was on. Then the refrigerator defrost period occurred after a certain accumulative length of time that the door had been open. There’s more logic to this than you may think, for the purpose of defrosting is to remove the frozen con­densate from the evaporator. This occurs most rapidly when the door is open, allowing warm, moist air to enter the freezer.

The refrigerator heaters in these systems are enclosed, with heavy electrical insulation and waterproof connections and wiring. They are clamped to the evaporator and often contain a fusible link to protect against over heating. Look for this link near the heater and check it for continuity with your ohm meter before condemning the heater. When replacing refrigerator heater, or making any repair involving the wiring harness, be sure that all connections are tight and waterproormid wrapped thoroughly and tightly with tape. Refrigerator manufacturers have used an alternate method of defrosting in the  most applications the chilled air from the refrigerator evaporator is discharged directly into the freezer compartment. When more cooling is called for in the refrigerator compartment, it takes this air from the freezer compartment.

In a typical application the refrigerator thermo­stat would open and close a baffle to admit air through a duct from the freezer compartment. If enough chilled air is removed to allow freezer temperatures to rise, the freezer thermostat turns the compressor on to provide more cooling to the freezer. Thus a chain reaction effect is created. The thermostats used normally sense the air temperature within the compartment rather than the temperature of an evaporator plate. This method of control, combined with the forced air movement found within these systems, produces more even and consistent temperature was previously possible
