What do I do when A1 appears?

Turn the oven off and let it cool. Once it has cooled and the door unlocks, the code clears by itself.

Is it safe to open the door?

Wait until the door unlocks. It stays locked while the oven is hot, which protects you from steam and heat.

When should I call you?

If A1 returns after the oven has cooled and been used normally. We find the cause, quote the price in writing, and give a 30-day workmanship warranty.

Fisher & Paykel Steam Oven Code A1: The oven has overheated

What A1 means

On Fisher & Paykel OS24 and OS30 steam and combi-steam ovens, code A1 means the oven has overheated. The control has detected a temperature above what it allows and stops heating to protect the oven. Allow the oven to cool; once it has cooled and the door is unlocked, the code disappears. Until then the display shows A1 and cooking is not available.

Common causes of A1

Oven cavity overheated
Door locked while the oven cools down
Temperature control or sensor reading above its limit

✓ One safe check you can try

1. Switch the oven off and leave the door closed until it unlocks on its own. 2. Wait for the oven to cool fully before touching the interior. 3. Remove anything stored in or on the oven that blocks the vents. 4. Turn the oven back on and run a short steam setting. 5. If A1 returns, stop and call us.

! Why to stop there

An oven that overheats more than once points to a control or temperature sensing problem
Overtemperature is a safety limit that must not be bypassed
Panels and wiring near the cavity are hot and carry mains power

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.
