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. |
