Alarms
There are four possible conditions that will cause the alarm tone to sound.
High Temp Alarm
If the temperature inside the cabinet has exceeded 23ºF (-5ºC) for 1 hour or more of normal operation, the
HI TEMP LED will illuminate, the HIGH TEMP Alarm will sound and the cabinet temperature is shown in the
display. The LED and temperature alarm will remain active until the cabinet temperature is below 23ºF (-5ºC).
The audible alarm can be turned off by pressing ALARM OFF key.
Door Ajar Alarm
This alarm will sound to alert you that the door has been open for 5 minutes or more. The DOOR AJAR LED
will illuminate and the audible alarm will sound until the door is closed.
The audible alarm can be turned off by pressing the ALARM OFF key or by closing the door. If the door is ajar
for 15 minutes, the interior light will turn off.
Temp Sensing Error Alarm
The sensor alarm signals you that a problem exists with a temperature sensor. The audible alarm will sound
after one (1) hour and the display will alternate between “E8” or “E9” and -10°F (-23°C) at ½ second intervals.
The control will then enter a mode that runs the freezer in a manner that maintains the factory set cabinet
temperature.
The audible alarm can be turned off by pressing the ALARM OFF key.
Stuck Key Alarm
The stuck key alarm will sound if the control reads a keypress for longer than 30 seconds. The audible alarm
will sound and will be limited to one minute and will stop automatically. The display will alternate between “E7”
and -10°F (-23°C) at ½ second intervals intervals and the control will run the freezer continuously until the
condition is resolved.
The audible alarm can be turned off by pressing the ALARM OFF key.
