Fisher & Paykel Oven Alert A1: Oven Has Overheated

What A1 means

On current Fisher & Paykel OB24 and OB30 Series 7 and 9 built-in ovens, such as the OB30SDPTX1 and OB24SDPTX1, A1 is an alert telling you the oven has overheated. The display shows A1 and heating stops. Once the oven has cooled and the door has unlocked, the code clears by itself. The same A1 wording appears on Fisher & Paykel steam ovens, speed ovens and ranges.

Common causes of A1

Cooking or a self clean that pushed the cavity beyond its limit
A blocked vent or poor airflow around the oven
A cooling fan that is slow or not running
A temperature sensor or control that misreads heat

✓ One safe check you can try

1. Turn the oven off and leave the door closed; let it cool completely, which can take an hour or more. 2. Do not force the door open if it is still locked. 3. When the door unlocks and A1 disappears, check that no vents are covered by foil, trays or cabinet items. 4. Try a normal bake at a moderate temperature. 5. If A1 comes back quickly, call us.

! Why to stop there

Repeated overheating alerts can damage the control and nearby parts.
Finding out why it overheats means checking fans, sensors and airflow with the oven apart.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

A1A1 questions

Is it normal to see A1 once?

A single alert after a very long or very hot session can happen. Let the oven cool fully; if the code clears and stays away, keep an eye on it. Repeated alerts need a technician.

Why is my oven door locked?

The door stays locked while the oven is too hot to open safely. Once it has cooled enough, the lock releases and the A1 code disappears on its own.

Does A1 mean the oven is broken?

Not by itself. It is a warning that heat got too high. We look for the reason, such as airflow or a cooling fan, before deciding on a repair.
