29. WATER SOLINOID remove / replace All water flows through the water filter before being routed to the icemaker or dispenser. There are 3 solenoid valves which have color coded rings. The single primary valve supplies water to the filter (white ring). The water then returns to the secondary valves (black ring). The valve feeding the dispenser is designated with a green ring. The icemaker with an orange ring. All solenoids have a resistance of approximately 385Ω and are replaced as an assembly. To release the water line, push in on the tubing and colored fitting.

45. EVAPORATOR Evaporator Area Wiring Defrost Heater Evaporator Fan Motor Defrost Sensor and thermal fuse

46. EVAPORATOR Adaptive Defrost Cycle • This is an Adaptive Defrost Circuit which monitors ambient temperature, humidity, door openings, and temperature variances (load). The time between defrost cycles will vary depending on the above conditions. • The defrost process resets every time power is disconnected to the refrigerator. The cycle is controlled through the microprocessor on the motherboard. After the first 4 hours of compressor run time, the refrigerator will start a defrost cycle. • DEFROST CYCLE TIMELINE • At defrost cycle START, the heater will turn ON. When the temperature of defrost sensor reaches 7°C / 45°F, the heater will turn OFF. • For an additional 7 minutes, the compressor and evaporator fan will remain off and the fresh food damper stays closed. • After the 7 minute pause, the compressor starts and operates for 5 minutes. The evaporator fan will remain off and the fresh food damper stays closed. • After 5 minutes of compressor run time, the evaporator fan motor will start recirculating air within the freezer compartment. The damper will remain closed. • 3 minutes after the fan starts, the fresh food damper will open, completing the defrost cycle. • - - - - - - - - - - - • If there is a failure within the defrost circuit (heater, thermal fuse, sensor) or if the defrost sensor does not reach 7°C / 45°F within 120 minutes, ED will be displayed on the door display and the compressor will reenter the cooling mode. A problem at the motherboard could also affect the defrost cycle. ED

47. COMPRESSORS PBFS21****, PBFS21T*** and PRFS25*** Models are Energy Star models and use a 3 phase variable speed compressor controlled through the mother board and a compressor inverter control. The inverter control shown below is mounted on the compressor terminals. RBFS21S*** models use a conventional single speed compressor with PTC and overload mounted on the compressor terminals. Compressor operation is controlled through relays on the motherboard. Compressor Inverter / Control
