actually means.
The alarm beeps and the notification icons appear when the door has been open too long. On TR-42 and TR-48 columns that is more than 5 minutes. On the 15 inch and 24 inch undercounter units it is 7 minutes. It is an alert you can switch on or off with the ALARM key.

True Residential refrigerator repair
Built-in refrigerator
Flush with the cabinets, serviced from the front, and almost always repaired rather than replaced.
Refrigerator column
Separate refrigerator and freezer towers, each with its own sealed system — so a failure stays on one side.
Undercounter refrigerator
A single 15 to 24 inch unit under the worktop — front-vented, tightly enclosed, and easily starved of air.
