What to do when DOOR ALARM shows on the freezerKind of codeMode, not a failure
A setting the freezer was put into, often by accident or by the store it came from, rather than a part that broke: a showroom or demo mode that lights the display while the compressor stays off, a fast freeze left running for days, a Sabbath setting that silences the alarms, a control lock, a door alarm reminding you the door stood open. Nothing has worn out, and the freezer's own buttons or manual put it back.
Usually leads toNo repair
Close the door or drawer fully; on columns, pressing ALARM stops the buzzer.
Shows up asFreezer Error Code
A freezer error code appears on the display: letters and digits, a flashing temperature, or a warning symbol, sometimes with an alarm and sometimes with the freezer still running.

Before you book,
in this order.
Each step comes from True Residential's own guidance for DOOR ALARM on its freezers. Follow it to the end: the last card says whether this is a visit.
Close the door or drawer fully; on columns, pressing ALARM stops the buzzer.
Check for anything holding the door or drawer open, such as a bin that is not pushed in.
If the alarm sounds with the door shut, look at the gasket and book a visit if it seals well.
Cleared?
The freezer is holding its temperature again and no part had to be replaced. If the same code comes back within a few days, or the packages start to soften again, book it as a fresh problem.
What not to do
The door alarm is not a temperature warning, although a door left open long enough can lead to HIGH TEMP. It also does not stop the freezer from cooling.
