Ambient heat is one of the most common causes of “not cooling” complaints that are actually capacity and airflow issues, not a refrigeration fault.
In a hotter room, the fridge has to reject more heat through the condenser, so pull-down takes longer and recovery after door openings is slower.
If the unit is boxed in or tight to a wall, hot air recirculates around the condenser and the cabinet may run continuously yet still drift warm and alarm.
Busy kitchen behaviour (frequent openings, warm product loading) compounds the issue, so you can see temperature excursions and nuisance alarms even though the compressor is running.
Practical fixes that often help immediately: improve ventilation space, move the cabinet away from cooklines and hot appliances, reduce door-open time, and avoid loading warm stock until it has cooled safely.
