TROUBLE |
TESTING |
| I/M-SENSOR (R on Twin I/M units) |  |
Ice Maker Sensor Error- open or short-circuit, connector failure. Cause is also a temperature reading > 122°or < -58 ° F | The voltage at MAIN PCB Sensor between 4.5V~1.0V |
| R-SENSOR |  |
Refrigerator Room Sensor Error- open or short-circuit, connector failure. Cause is also a temperature reading > 122°or < -58 ° F. | The voltage at MAIN PCB Sensor between 4.5V~1.0V |
| DEFROST SENSOR OF R ROOM |  |
Ref. Defrost Sensor Error- open or short-circuit, connector failure. Cause is also a temperature reading > 122°or < -58 ° F. | The voltage at MAIN PCB Sensor between 4.5V~1.0V |
| R-FAN ERROR |  |
This error indicates the Refrigerator Evap Fan is not spinning at the correct RPM or the fan feedback line is open. | Fan voltage at MAIN PCB shall be between 7V~12V |
| I/M FUNCTION ERROR(R on Twin I/M) |  |
This error indicates the Ice tray has not returned to level after an ice harvest. The error is displayed after three failed attempts. | Replace I/M |
| R-DEFROSTING ERROR |  |
Refrigerator Room defrost heater- open or short-circuit, connector failure, or defective temperature fuse/bi-metal. Defrost on over 80 minutes. | Disconnect defrost connector from PCB, check resistance |

Freezer Compartment Sensor Error- open or short-circuit, connector failure. Cause is also a temperature reading > 122°or < -58 ° F. | The voltage at MAIN PCB Sensor between 4.5V~1.0V |
| F-DEF-SENSOR |  |
Freezer Room Defrost Sensor Error- open or short-circuit, connector failure. Cause is also a temperature reading > 122°or < -58 ° F. | The voltage at MAIN PCB Sensor between 4.5V~1.0V |
| F-FAN ERROR |  |
This error indicates the Freezer Evap. Fan is not spinning at the correct RPM or the fan feedback line is open. | Fan voltage at MAIN PCB shall be between 7V~12V |
| C-FAN ERROR |  |
This error indicates the Condenser Fan is not spinning at the correct RPM or the fan feedback line is open. | Fan voltage at MAIN PCB shall be between 7V~12V |
| FRENCH DOOR ICE ROOM SENSOR |  |
Ice Room Sensor Error- open or short-circuit, connector failure. Cause is also a temperature reading > 122°or < -58 ° F. | The voltage at MAIN PCB Sensor between 4.5V~1.0V |
| F-DEFROSTING ERROR |  |
Freezer defrosting heater- open or short-circuit, connector failure, or defective temperature fuse/bi-metal. Defrost on for over 80 minutes. | Disconnect defrost connector from PCB, check resistance. |
| FRENCH DOOR ICE ROOM FAN ERROR |  |
This error indicates the Ice Room Compartment Evap. Fan is not spinning at the correct RPM or the fan feedback line is open. | Fan voltage at MAIN PCB shall be between 7V~12V |
| Uart ERROR COMMUNICATION |  |
This error is not applicable, if the error is detected during diagnostic testing please ignore it. | No Repair Necessary |
