True Door Ajar Alarm: the door has been open past seven minutes

True's control gives a door seven minutes before it raises a door-ajar alarm, long enough for normal loading and unloading but short enough to catch a door left resting against a shelf or bottle.

What to do when Door Ajar Alarm shows on the home appliance

Kind of codeSensors

A sensor is giving a reading the control does not trust, and on the upkeep side that is often dirt rather than damage: dryer moisture strips coated with fabric-softener film, a refrigerator sensor iced over, a turbidity sensor in a dishwasher filmed with residue. Cleaning the strips with the appliance unplugged, defrosting and drying, or running a cleaning cycle often clears it; a code that returns after that points to a part, and that is a repair.

Shows up asAppliance Maintenance Code or Reminder Light: Filter, Descale, Vent Check

An appliance maintenance code is a reminder, icon or short code on a display asking for a filter change, descaling, a tub clean, rinse aid or an exhaust check rather than reporting a broken part.

True Residential units carry commercial-style cooling into the home, and their undercounter coils and heavy door gaskets need the same regular cleaning a restaurant unit gets.

Before you book,
in this order.

Each step comes from True Residential's own guidance for Door Ajar Alarm on its home appliances. Follow it to the end: the last card says whether this is a visit.

01

Close the door fully and confirm it latches or seals rather than resting against a nearby object.

02

Check for a shelf, bottle or bin that could be holding the door slightly open at the hinge side.

03

Clean the door gasket with a mild detergent and water if it looks stiff or is not sealing evenly around the frame.

04

If the alarm continues with the door confirmed shut, book a visit so the door switch and gasket can be checked.

Still there?

It usually turns into whole-home maintenance visit. Book with the code and the model number.

What not to do

This is a door-position alarm, not a temperature alarm on its own, though True often raises both together once a door stays open long enough to also warm the cabinet. Cleaning the gasket calls for the unit to be turned off first, per True's own cleaning steps.

Questions
about Door Ajar Alarm.

Can I clear Door Ajar Alarm myself?
Close the door fully and confirm it latches or seals rather than resting against a nearby object. If it comes back, it needs a visit.
How long can a True door sit open before the alarm sounds?
About seven minutes, according to True's own control documentation — enough time for normal loading and unloading, but the alarm will still catch a door left ajar longer than that.
Does the Door Ajar Alarm mean my True unit is also running warm?
Not necessarily on its own, but a door left open long enough to trigger this alarm will also start to warm the cabinet, and True's control can raise the high-temperature alarm alongside it if the door stays open.
Do I need to turn my True unit off before cleaning the door gasket?
Yes — True's cleaning steps start with turning the unit off before using a mild detergent and water on the gasket, moving to a diluted bleach solution only where mold or mildew is present.

Still showing Door Ajar Alarm?

A booking goes further when it has the reminder or code as shown, the model number from the rating plate, and a word on when that filter, screen or tub was last cleaned. With those three, the office can pack the right filter or cleaner for your appliance.
