Fresh Food Ice Maker Diagnostic Mode Activate: Press ٨ and V temperature pads for up to 10 sec. simultaneously. Press + or - to move forward or backward through tests. Deactivate: Press + for up to 10 sec. FFIM Diagnostic Mode will automatically deactivate after 5 min. of inactivity. NOTE: Silence alarm. Test To activate test Passing Result 52C Ice Maker Thermistor Activates FZ display shows temperature sensed by Ice Maker Thermistor. automatically "OP" if open; "SH" if short 55C Water Valve Set Remove ice tray to collect water into a measuring container to measure wa- ter fill. If collecting water into ice tray, first perform test 63C to empty ice tray. 57C Evaporator Fan (FFIM) Set "On" on FZ display when fan activated, "OFF" when deactivated. Ice Level Sensor 58C 63C Twist Tray Activates automatically Set Remove ice bucket. Allow bail arm to drop freely. Pass if no alarm when tray returns to "home" position. Hold bail arm up. Pass if alarm sounds when tray returns to "home" position. This test runs continuously until another test is selected. Remove ice bucket. FZ display shows "1" and "GOOD". Variable Capacity Compressor (VCC) Diagnostics (select models) If test 38 fails, diagnose as follows: CAUTION All electrical parts and wiring must be shielded from torch flame. DO NOT allow torch to touch insulation; it will char at 200°F and flash ignite (burn) at 500°F. Excessive heat will distort the plastic liner. → Check at the connector from the power cord harness into the inverter board, located in the machine compartment. (PUR and WHT wires) Is Inverter Board receiving 115 VAC from power supply? → Check at Inverter Board on Compressor yes (BLK and RED wires) Is Inverter Board receiving 10-15 VAC and 1-5 VDC from Main Control Board? → Remove inverter box from the compressor and check resistance yes across compressor winding pairs as shown. Is resistance across all winding pairs equal? no no no → Check connections from Inverter Board to Compressor yes Are connections from Inverter Board to Compressor intact? no • Check voltage supply. • Check and repair power cord harness wiring and connections. → Check at Main Control Board (BLK/WHT and RED/BLK wires) no Is Main Control Board sending 10-15 VAC and 1-5 VDC to Inverter Board? yes Identify and repair damaged wires or poor connections between Main Control Board and Inverter Board. Replace Compressor and Inverter Board. Replace Main Control Board. Identify and repair damaged wires or poor connections between Inverter Board and Compressor. yes VCC Resistance Check Check resistance between terminals 1 and 2, 2 and 3, 3 and 1. If all resistances are equal, compressor is operative. Replace Inverter Board FREEZER ICE MAKER INFORMATION (Where Applicable) Test Cycling: Remove cover by inserting screwdriver in notch at bottom and prying cover from housing. Use screwdriver to rotate motor gear counterclockwise until holding switch circuit is completed. All components of ice maker should function to complete the cycle. Water Fill Volume: The water fill adjustment screw will change the fill time. One full turn is equal to 20cc (.68 oz.). The correct fill is 102 to 130cc (3.4 to 4.3 oz.). When a water valve is replaced, the fill volume must be checked. Water Fill Adjustment Motor Gear Mounting Plate Screw N TUR Mounting Plate Screws Timing Gear System Diagnostic Mode Activate: Press ٨ and ٧ for up to 10 sec. simultaneously. Deactivate: Press + for up to 10 sec. Diagnostic Mode will automatically deactivate after 5 min. of inactivity. Note: Silence alarm. • Tests marked with "*" may not be applicable to this unit and will not be displayed in System Diagnostic Mode. • Tests displayed in diagnostic mode but not described below are for internal purposes only; advance through. • View UI display for "on," "off," "CL," "OP," "SH," "LO," "HI" or numerical results of tests. • Listen for operating sounds; feel for heat or air flow as appropriate to determine results of tests. Test To activate test: Passing result -- First Screen -- All LED lights on UI illuminated -- Second Screen -- All segments on UI temperature displays illuminated -- Third Screen -- Blank UI display, no lights illuminated, no shadowing; "-" and "+" blinking on FF display side to show location. 28 Dispenser Paddle Press disp. paddle "on" on UI when depressed; "off" when released 1* Standard Set Compressor Compressor running when "on"; stopped when "off" 2 Defrost Heater Set Defrost limit switch must be closed; verify "CL" in test 26. Feel for heat from defrost heater when "on". If "OP" in test 26, heater will not activate. 3 FF Light Set With FF door open, FF lights on when "on"; off when "off" 8 Water Valve Set (Dispenser) Be prepared to collect water at dispenser.

Motor running when "on"; motor stopped when "off" 11 Cube/Crush Set Solenoid FF door must be closed. Do not leave solenoid in activated state. Solenoid activated when "on"; deactivated when "off" 41* Perfect Temp Drawer Set (PTD) PTD UI illuminated when "on", off when "off" 12* VCC Condenser Fan Set Fan running when "on"; stopped when "off" 38* VCC Compressor Set Compressor running when "on"; stopped when "off" 15 Evaporator Fan Set Fan running for minimum of 10 sec. when "LO" or "HI"; stopped when "off". Feedback failure if fan starts but runs less than 10 sec. Listen for speed change from "LO" to "HI". 36 Ice Chute Door Depress ice chute door "OP" on UI when manually opened; "CL" when closed. Or, using "power on- or set off", "OP" on UI when solenoid activated, "CL" when deactivated 22 Damper Set With inspection mirror, observe damper open when "OP"; closed when "CL" 23 FF Door Open/close FF door "CL" on UI when door closed; "OP" when open 24 FZ Door Open/close FZ door "CL" on UI when door closed; "OP" when open 26 Defrost Limit Switch Activates automatically "CL" on UI when closed; "OP" when open 29 FF Thermistor Midlevel Activates automatically UI shows temperature sensed by FF thermistor; pass if within 10°F of temperature measured with gauge at mid-level FF thermistor location.
