RCA freezer beeps and shows AL or an alarm icon; temperature may be high or door may have been left open.

Safety first: No internal work is required for basic checks. Unplug the unit before testing the door switch.

Steps to clear alarm:

• 1. Confirm door closure: Ensure the door is fully closed and nothing is blocking it. Check that the gasket is clean and flexible.
• 2. Silence alarm: Use the alarm reset or mute button on the control panel (if equipped). This will silence the beeper while the unit recovers temperature.
• 3. Check door switch: Locate the door switch (usually near the top front frame). Press it by hand; the interior light should turn off. If the light stays on, the switch may be stuck or faulty.
• 4. Test door switch: Unplug the freezer, remove the switch, and check continuity with a multimeter. It should change state (open/closed) when pressed. Replace with an RCA-compatible door switch if defective.
• 5. Allow temperature recovery: After confirming the door is sealing, allow several hours for the freezer to return to set temperature. The alarm should clear automatically.

Tip: Frequent door openings or loading large warm items can trigger alarms; minimize door open time to maintain stable temperatures.
