A defrost occurs after a pre-determined length of compressor run hours has been reached, similar to refrigerators equipped w ith an electro-mechanical defrost timer. How ever, the compressor run time betw een defrost cycles changes or adapts depending upon a recent history of defrost lengths (the time it takes for the defrost thermostat to open once the defrost heater has been turned on). The compressor run time betw een defrosts w ill be one of the 4 values under normal operation, defined as 8, 12, 16, or 72 compressor run hour lengths. When the refrigerator is first installed or after a pow er interruption, the first defrost w ill occur 4 compressor run hours from the time pow er is applied. After the initial defrost, the length of the compressor run hours betw een defrosts (8, 12, 16, or 72) depends upon the length (time) of the last defrost. To reach (Vacation Mode) 72 hours of accumulative compressor run time betw een defrost intervals, 3 things must happen. 1. The defrost interval must have advanced to 16 hours of accumulated compressor run time. 2. Both refrigerator and freezer door must have remained closed since the last defrost cycle. 3. The defrost thermostat must have opened in less than 19 minutes during the last defrost cycle. Vacation Mode Defrost Interval Interruption 1. On all current series controls, the vacation mode defrost interval is interrupted w ith a door opening. When a door is opened, the refrigerator w ill defrost 8 hours from the time the door is opened and w ill revert back to the 8 hour accumulated compressor run time mode. 2. If w hile in vacation mode defrost, the defrost thermostat remains closed for 21 minutes or more, the next defrost w ill be 12 hours of accumulated compressor run time. A 6 minute dw ell time occurs after the defrost thermostat opens before the compressor and condenser fan motor w ill operate. If the defrost thermostat does not open w ithin 29 minutes from the start of the defrost cycle, the adaptive defrost control w ill terminate the defrost even though the defrost thermostat has not opened. Forced Defrost To force a defrost cycle, open and close either the freezer or refrigerator door light sw itch 4 times in a 8 second period. Allow at least 1/2 second betw een each sw itch condition. Important 1. The compressor must be operating w hen forcing defrost. 2. The evaporator fan motor is fan delayed through the defrost thermostat and w ill not function after a defrost cycle until the defrost thermostat closes. 3. To bypass the 6 minute dw ell time after a defrost or to terminate a forced defrost, disconnect pow er to the refrigerator for 30 seconds.
Input Voltage Readings and Checks L1 to L2 - line voltage should be present w henever the refrigerator is pow ered. K to L2 - line voltage should be present w ith cold control contacts closed. T to L2 - line voltage should be present w hen cold control contacts are closed, defrost terminator is closed, and adaptive defrost control is in defrost mode. R to L2 - line voltage should be present w ith refrigerator door open (door light sw itch closed). F to L2 - line voltage should be present w ith freezer door open (door light sw itch closed). Outputs Voltage Readings and Checks C to L2 - line voltage present w hen in refrigeration mode w ith cold control contacts closed.
