What Does Error AL Mean?

The Siemens refrigerator AL error indicates a temperature alarm, signaling that the internal compartment temperature has exceeded acceptable levels. This can lead to inconsistent cooling performance and may trigger an alarm beep, which can be temporarily dismissed but will return if the issue persists. Common causes include a malfunctioning temperature sensor or a rise in internal temperatures due to door issues or other cooling system failures.

Common Symptoms:

  • Alarm displayed (AL) often with temperature rising above set level
  • Refrigerator/freezer not cooling to expected temperatures
  • Possible alarm beep that can be dismissed but returns if condition persists

Possible Causes

  • Internal temperature rise above acceptable range (medium)
  • Temperature sensor detecting out-of-range values (medium)

How to Fix Error AL

DIY Fix Check door and internal temperature conditions

  1. Ensure fridge/freezer doors are fully closed
  2. Check if AL alarm persists after a period with doors closed
  3. Monitor internal temperatures if possible

DIY Fix Reset the appliance to clear temporary alarms

  1. Turn off the fridge/freezer via power switch or unplug
  2. Wait a few minutes
  3. Reconnect power and allow unit to stabilize

Technician Only Inspect temperature sensors and cooling system

  1. Measure and test internal temperature sensors (NTC) for proper resistance/operation
  2. Check cooling components (evaporator, compressor, refrigerant circuit) if temperature alarms persist
  3. Evaluate for possible sensor replacement or cooling system repair

Parts needed: Temperature sensor (NTC), Potential cooling system components depending on diagnosis

🛑 When to Call a Pro:
  • If AL alarm persists after reset and basic checks
  • If temperatures remain out of range despite doors closed and proper operation
