Call an engineer if any of the below apply after a power cut:

No cooling restart: the cabinet powers on but the temperature continues rising and the compressor does not start even after the usual delay.

Repeated tripping: the plug, breaker, or RCD trips when the cabinet starts.

Persistent alarms: high temperature alarm won’t clear after the cabinet has had time to pull down, or the display shows an error code you cannot identify.

Unusual symptoms: burning smell, buzzing/overheating at the plug, visible damaged cable, or unusual noises.

Stock risk: you cannot verify safe temperatures with an independent probe and need a quick decision for food safety.

If you suspect a surge/brown-out during an ESB event, treat that as an engineer job as well. Electrical surges can damage controllers, relays, or power supplies, and continued use can cause repeat failures.
