When should I call an engineer for fridge icing issues?

Call an engineer when the issue is repeating, affecting temperature control, or involves parts staff should not touch. In particular:

The fridge won’t hold safe temperature or you see repeated HACCP deviations.

You’ve done basic checks (door seals, airflow/overpacking, drain clear, door discipline) and ice returns within days.

The fan isn’t running, airflow is poor, or you suspect the evaporator is fully blocked.

You see error codes/alarms, unusual electrical smells, or signs of damaged wiring.

Ice is so heavy that removal would require tools. Do not chip or scrape around the evaporator as it can puncture the coil and turn a service call into a major repair.

Before you call, note the model and serial, take photos of the icing pattern, and record cabinet temperatures and when the problem started. This speeds up troubleshooting and parts identification.
