Enquiry preparation
Freezer: make a short sequence of events
For a freezer enquiry: Describe selection, operation and outcome in that order. Add anything that still responds normally, keeping your observation separate from a suggested failed component.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Retain the message, visible frost pattern and any recent interruption. Keep covers in place and do not chip ice or use improvised heat to investigate.
How this supports the discussion
The freezer reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Confirm the proposed attendance
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
