Freezer alarm beeps intermittently with no obvious error code on display.

Safety first: Do not disable alarms permanently; they protect food safety.

Steps to address nuisance alarms:

• 1. Confirm actual temperature: Use a thermometer to ensure the freezer is maintaining safe temperatures.
• 2. Check door switch and gasket: Ensure the door is closing fully and the switch is reliable. Replace if intermittent.
• 3. Power reset: Unplug for 5 minutes to reset the control. If alarms stop, monitor for recurrence.
• 4. Inspect sensors: Test thermistors for proper resistance. Replace any that are out of spec.

Note: If alarms continue and temperature is unstable, have a technician evaluate the control system.
