Give the appliance room to release heat
Follow the manufacturer clearances around the cabinet and keep external ventilation areas unobstructed. Built-in models depend on correctly designed airflow paths, so do not cover grilles or fill gaps without checking the installation specification.
Dust cleaning should be limited to user-accessible areas described in the manual. Disconnect power when instructed and avoid bending exposed pipework or moving a heavy unit alone.
Monitor temperature instead of guessing
Use an appropriate appliance thermometer and minimise unnecessary door opening. Allow hot food to cool safely before storage according to food-safety guidance, and avoid packing containers against internal air channels.
If temperature rises, record whether both compartments are affected and whether the compressor, fans or display behave differently. Protect high-risk food first rather than waiting for a repair decision.
Act early on changing symptoms
Repeated clicking, continuous running, heavy frost, unusual heat, leaking water or a door that no longer seals deserve attention. A small change in behaviour can provide earlier clues than complete cooling loss.
Share temperature readings, model details and symptom timing in the booking. This gives the inspection a clearer starting point without assuming which component has failed.
This guide provides general preparation and safety information. Appliance design varies by brand and model; follow the manufacturer’s instructions and use qualified service support for diagnosis or repair.
