If ice returns after a previous visit, tell the service team about the pattern as well as the current condition. You do not need to identify the failed part. A few observations, linked to the right room and equipment, give the technician a useful starting point.
Describe where you see the ice
Is it around the doorway, on the evaporator, beneath its drain area or somewhere else? A photograph taken safely from floor level can show the location and extent. Include the date, room name and ADN Asset ID if available.
Icing can involve different parts of the installation. Door-related air entry, airflow, defrost operation and drainage may all be relevant to an investigation. The appearance alone does not establish the cause or the repair needed.
Explain the timing
- When did you first notice it, and how quickly has it changed?
- Did it return after earlier service? Have that report or work order available.
- Have deliveries, door traffic, loading or the room’s use changed?
- Are there display messages, unusual sounds or temperature concerns?
Prepare for the assessment
Identify a site contact and explain any restrictions on room access. Let the team know what product is stored and which areas must remain operational. Record any available readings with the time and measurement location; a single number without context is less useful.
Keep electrical panels, guards and refrigerant work for qualified personnel. Do not chip at coils, use an open flame or change controls to hide the symptom. Follow your site’s food-safety procedures for affected product and manage any slippery access areas through your normal workplace procedures.
Connect the follow-up to the same equipment
Keeping the report and new observations against the same Asset ID makes recurring concerns easier to discuss. ADN can review the findings and explain the proposed repair scope. Call 604-945-0788 for a time-sensitive equipment concern.
