Thank you for providing the model number. I see Barbara provided you with great information. However, your model does not have a battery to replace. The alarm in this freezer is triggered by the thermostat. If the temperature gets above 15 degrees, a set of contacts in the thermostat will send a signal to the alarm. You can check the temperature by placing a thermometer between some packages, air temperature is not a good check. If the temperature is below 8 degrees and the alarm is sounding, the control will need to be replaced. If the temperature is above 15 degrees, first set the control to a colder setting. If the temperature does not drop, a technician will be needed to check the system.
If pressing the alarm off button or resetting the board by disconnecting the freezer from the outlet for 5-10 minutes doesn't work, the control will most likely need to be replaced. Looking through the
parts list diagram
, the control/module for this model is no longer available and the manufacturer has not recommended a substituted part that would work. Chest freezers have an average life span of 10 years. The system is showing this unit was made around 1998. If you can't live with the beeping you may consider replacing the unit.
