A. With cold evap. (< -12°C (10°F)), initiate Manual Defrost, then initiate Diagnostic Mode (press UNIT ON/OFF key
every 20 seconds to keep in Diagnostic Mode) and observe evap. temp. If temp. exceeds 7°C (45°F) and defrost
lasts longer then 5 minutes, error code is false. Clear error code. If error code is not false:
1. Check continuity of Grey/White wire from defrost heater to J2-3 on control board. Reconnect / repair
Grey/White wire.
2. While in defrost, check for 230 V AC at P2 on control board. If no voltage, replace board.
3. Check continuity of Blue wire from defrost terminator to P2 on control board. Reconnect / repair Blue wire.
4. Check resistance of defrost heater (see wire diagram for proper resistance). Replace heater if defective.
5. Check electrical connections and operation of defrost terminator (Cut-in -1°C (30°F)/Cut-out 21°C (70°F)).
Reconnect / repair or replace terminator.
6. Reference wiring diagram to identify components in same White wire circuit as defrost heater. Check all White
wire electrical connections and continuity from defrost heater to P4 on control board.
A. With cold evap. (< -12°C (10°F)), initiate Manual Defrost, then initiate Diagnostic Mode (press UNIT ON/OFF key
every 20 seconds to keep in Diagnostic Mode) and observe evap. temp. If temp. does not
exceed 41°C (105°F),
error code is false. Clear error code. If error code is not false:
1. Check Blue wire connection at control board (P2). If connected to wrong pin, connect correctly.
2. Check Grey/White wire connection at control board (J2-3). if connected wrong or bad connection, reconnect /
repair.
3. Check for proper mounting & location of evap. thermistor, defrost heater & terminator. Remount correctly.
4. Check for electrical short of Blue wire to another circuit. Repair Blue wire &/or electrical connections.
5. Check operation of defrost terminator (Cut-in -1°C (30°F)/Cut-out 21°C (70°F)). Replace if defective.
A. With cold evap. (< -12°C (10°F)), initiate Manual Defrost. If compressor starts 5 minutes (10 minutes in
ICB700TF/I) after defrost is initiated, check Grey/White wire and continuity from defrost heater to J2-3 on control
board. Reconnect / repair Grey/White wire.
A. With cold evap. (< -12°C (10°F)), initiate Manual Defrost. If compressor starts 5 minutes (10 minutes in
ICB700TF/I) after defrost is initiated, check Grey/White wire connections and continuity from defrost heater to J2-3
on control board. Reconnect / repair Grey/White wire.
B. Check for proper mounting and location of evap. thermistor, defrost heater & terminator. Remount correctly.
C. Check Blue wire connection at control board (P2). If connected to wrong pin, connect correctly.
D Check for electrical short of Blue wire to another circuit. Repair Blue wire &/or electrical connections.
A. With cold evap. (< -12°C (10°F)), initiate Manual Defrost, then initiate Diagnostic Mode (press UNIT ON/OFF key
every 20 seconds to keep in Diagnostic Mode) and observe evap. temp. If temp. exceeds 7°C (45°F), error code is
false. Clear error code. If error code is not false:
1. Check Blue wire connection at control board (P2). If connected to wrong pin, connect correctly.
2. Verify proper location of Grey/White wire at control board (J2-3). if connected wrong or bad connection, recon-
nect / repair.
3. Check for proper mounting & location of evap. thermistor, defrost heater & terminator. Remount correctly.
A. Check for jammed cube in icemaker.
B. Reference wiring diagram to identify components in same White wire circuit as water valve solenoid. Check all
White wire electrical connections and continuity from water valve solenoid to P4 on control board.
