Edgestar Freezer Error Code --

The "--" indicator means the current internal temperature is outside the range the display can show, which is -9 to 37°C (16 to 99°F). This is a normal display behavior, not a fault code. It typically appears during initial startup or in unusually warm or cold conditions, and it clears automatically once the temperature falls within the displayable range.

Yes, the freezer is safe to operate when "--" is shown. The appliance continues to cool and function normally; only the numeric display output is affected. Your food remains at the target temperature even while the display cannot render a specific number.

In most cases, "--" simply reflects a temperature outside the displayable range and does not indicate a failed sensor. However, if the indicator appears continuously during normal operating conditions and never transitions to a numeric reading, it may be worth checking whether the sensor is functioning correctly. A persistently missing temperature reading under normal conditions would be the key sign that further diagnosis is warranted.

No repair is needed because "--" is not a malfunction. Simply allow the freezer time to reach a stable operating temperature and the numeric display will return on its own. If the indicator persists for several hours during normal operation, verify that the unit is not located in an excessively hot space and that the door is sealing properly.

A reset is not necessary and will not resolve the "--" indicator any faster than allowing the unit to reach a stable temperature naturally. Since this is a display range limitation rather than a stored fault, there is no error to clear. The display will update automatically once the sensed temperature is within the -9 to 37°C (16 to 99°F) window.
