LG fridge freezer alarm beeping and temperature warning

A temperature alarm on an LG side-by-side usually means the cabinet is getting too warm, or the machine thinks a door is open. It does not always mean a major fault, but a few simple checks will help narrow it down.

1. **Check actual cooling first** - Is the freezer still keeping food properly frozen and the fridge section cold? - If you have a thermometer, aim for roughly **-18°C in the freezer** and **3–5°C in the fridge**. - If temperatures are rising, the alarm is doing its job and the cause needs finding.

2. **Confirm the doors are definitely closing properly** - Check nothing is preventing the doors from shutting fully. - Look at the **door seals** for gaps, splits, dirt or twisted sections. - Make sure the appliance is level and the doors are not dropping slightly on the hinges.

3. **Listen for the evaporator fan** - Open and close the freezer door and listen for a fan running shortly after the door is shut. - If the fan is not running, or is noisy, cold air circulation can be affected and trigger the alarm.

4. **Look for signs of icing** - Heavy frost or ice build-up inside the freezer back panel can indicate a **defrost problem** or airflow issue. - That would need further diagnosis.

5. **Clean the condenser area** - If accessible, clean dust from ventilation grilles/condenser areas and make sure there is good airflow around the appliance.

6. **Door switch/sensor possibility** - If cooling is normal but it still alarms, a **door switch/sensor** or wiring issue is possible, as the fridge may think the door is open.

7. **After a power cut or warm loading** - If it was recently switched off, loaded with lots of shopping, or left open for a while, it may simply need time to recover.

Safety reminder: **isolate the appliance from the mains before inspecting any internal parts**. If cooling is poor, there is heavy icing, or you suspect an electrical fault, it is best to use a **qualified appliance engineer**. Any sealed refrigeration work must be left to a refrigeration engineer.
