A1 alarm or code, freezer temperature too high, food starting to soften, audible alarm may sound.

Safety first: No internal electrical work is needed for basic checks, but unplug the appliance before removing panels.

Step-by-step checks:

• 1. Check door closure: Ensure the freezer door is fully closed and not obstructed by food or ice. Inspect the door gasket for gaps, tears, or dirt.
• 2. Allow recovery time: If you recently loaded a large amount of unfrozen food, allow 12–24 hours for the temperature to stabilize. Keep the door closed as much as possible.
• 3. Verify fan operation: With the door switch held closed, listen for the freezer fan. If silent, investigate fan issues as described in fan-related entries.
• 4. Check for frost build-up: Heavy frost on the evaporator cover indicates a defrost problem; see defrost-related faults.

When to call a technician: If A1 persists despite good door seals and fan operation, a sealed-system issue (refrigerant leak, weak compressor) may be present and requires a refrigeration engineer.
