# Sub-Zero refrigerator beeping

### The fastest diagnosis is the code

If there is a code alongside the beeping, that is the shortcut — a door code and a temperature alarm sound identical and mean quite different things.

### Most beeping is a door

A door alarm is the commonest cause: a door left ajar, a seal that no longer grips, or a unit whose door is being held a few millimeters open by something on a shelf. On panelled built-in doors it can also be alignment — a door that closes but no longer sits square in its opening.

### The rest is temperature

A temperature alarm means the cabinet has been outside its range long enough for the board to say so. If the display looks normal now, the alarm is telling you about something that has already happened — after a power cut, or after a long door-open during a party or a delivery.

Alarm, not failure

What it usually means

Beeps that stop when the door is pushed

Beeping that returns after a reset

Alarm with temperatures that look normal

The fastest diagnosis is the code

If there is a code alongside the beeping, that is the shortcut — a door code and a temperature alarm sound identical and mean quite different things.

Most beeping is a door

A door alarm is the commonest cause: a door left ajar, a seal that no longer grips, or a unit whose door is being held a few millimeters open by something on a shelf. On panelled built-in doors it can also be alignment — a door that closes but no longer sits square in its opening.

The rest is temperature

A temperature alarm means the cabinet has been outside its range long enough for the board to say so. If the display looks normal now, the alarm is telling you about something that has already happened — after a power cut, or after a long door-open during a party or a delivery.

A door held a few millimeters open

The commonest cause by a distance: a bottle on a shelf edge, a drawer not quite home, a door nobody uses. Check every one, including those.

A seal that no longer grips

The paper test settles it in under a minute. A door alarm and a temperature alarm sound identical and mean quite different things.

A door that closes but sits out of square

Common on heavy panelled built-in doors after years of use, or after a kitchen refit. It closes, and it still does not seal.

A temperature alarm about something already over

If the display looks normal now, the alarm is telling you about what happened earlier — after a power cut, or after a long door-open during a delivery.

Check every door and drawer

Including the ones nobody uses. A door alarm is the commonest cause by a distance, and it is often a drawer that is not quite home.

Do the paper test on the seal

A door alarm and a temperature alarm sound identical and mean quite different things. The paper test separates them in under a minute.

Note the pattern

Continuous, or in bursts, and whether it stops when a door is pushed. That pattern is most of what a technician would ask you on the phone.

Then book the visit

If the display looks normal and it is still beeping, the alarm is about something that already happened — say whether there was an outage or a long door-open.
