Section 3 - Service and Repair

THERMISTOR OUTAGE

If the refrigerator thermistor (T1) fails, the unit will continue to operate based on a preset time interval of 10 minutes on and 30 minutes off. The display will show “E1.”

TROUBLESHOOTING

Error Code

E1, E2 Bad thermistor errors. Replace thermistor. Check for thermistor errors by accessing "View thermistor

#status (2)." If the error code is repeated, the thermistor is open or shorted. If a temperature is displayed, the thermistor is not defective.

E3

This signals that the door (or bottom drawer) has

 

been left open for longer than 20 minutes. Close the

 

door to reset. If the light and display do not go off

 

when the door is closed, check to make sure the

 

magnet is positioned properly.

E5

This signals that the unit has been above set-point

 

for more than twelve hours by at least 10 degrees. If

 

the unit was just plugged in, leave for 24 hours to

 

see if the problem is corrected. If it is not corrected,

 

it is most likely a refrigeration system issue.

E6

This signals that the refrigerator section has been at

 

least 10 degrees below set-point for at least twelve

hours. This would most likely be caused by a bad relay and the circuit board.

After checking the errors be sure to clear the error log by performing service option 12.

Excessive Frost on evaporator

Shut down unit and thaw if frost is very thick. The unit may be used in an abnormal manner. If the unit will continue to be used in this manner the defrost length can be lengthened in the service menu to prevent future issues. Extending this length may be detrimental to the refrigerator temperature. During very long defrosts the temperature may rise higher than desired.

CAUTION

If frost is heavy, divert water from drain pan to prevent water on floor.

Noise

Some noise is normal, such as a hum from the fans/compressor.

Display is showing something other than “SP (38)” or “ER.”

Push one of the keys to see if the display is reset.

Turn unit on and off via the display pad.

Unplug unit, wait one minute, and plug back in. If any of these steps returns the unit to operation the unit was probably accidentally entered into a service mode.

Display is showing a random snaking of characters or a degree symbol is flashing.

The unit is in a special showroom mode. Hold the COLDER key and press the LIGHT key three times to exit.

Refrigerator too warm

Check the actual refrigerator temperature. If set to 38°F, the actual temperature should be between 36°F and 40°F during normal operation. Recent door openings, product loading, or defrost cycles will push the temperature higher for short time periods.
