What High temperature alarm
actually means.
The control has seen an unsafe product temperature for more than an hour. On True refrigerators the limit is 50°F. On the undercounter models it is 20°F for a freezer and 70°F for a wine cabinet. On the undercounter models, the same key press turns on both this alarm and the door ajar alarm.

Before you book,
in this order.
Each step comes from True Residential's own guidance for High temperature alarm on its refrigerators. Follow it to the end: the last card says whether this is a visit.
Check that the door is closed and look for a recent power loss or a big load of warm product.
Check the temperature of the food. The alarm means it has been at or above the limit for an hour.
If the cabinet does not recover, book a visit.
What not to do
It is not the door ajar alarm, which goes off after a few minutes with the door open. This alarm waits for a full hour at temperature.

Service indication on other makes
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.
In True Residential's own words
The electronic control will monitor temperatures and activate an alert if unsafe product temperatures are present for more than 60 minutes.
Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. Limits from True's 15 inch and 24 inch undercounter manual. The TR-42 and TR-48 columns show a "high temp" icon for refrigerator or freezer.
