Error codeE9
ApplianceRefrigerator
Reading E9 by series
UHRE515/524, UHWC524, UHBD524, UHRI124, UHRF124: door 2, the lower door, is open.
Echelon refrigerators, wine cabinets and beverage centers: thermistor 4 open or shorted. R, WC and CLR2160 units do not have it.
What you can try
On a newer unit, press the lower door fully shut and confirm that it latches. A door error is the one fault the manual says is shown on the display with a sound; all the others remain in memory and are read from the log.
The Echelon meaning comes with no owner step in the manual.
If E9 stays on
Should the code continue with the lower door closed, or if it is the Echelon thermistor fault, have a technician look at it.
Related codes
E8 is thermistor 4 shorted, the entry just before it in the log.

Plain language
What this code means
E9 is door 2 (lower) open on newer U-Line models and thermistor 4 open or shorted on Echelon models.
