Fisher & Paykel Speed Oven Alert A1: Oven Has Overheated

What A1 means

On Fisher & Paykel OM24 and OM30 combination microwave speed ovens, such as the OM24NDTDX1 and OM30NDTDX1, A1 tells you the oven has overheated. The display shows A1 and the oven stops. Allow it to cool, then power it down and back on. The same wording appears on other Fisher & Paykel ovens, but this page covers the speed oven.

Common causes of A1

A cooking session that raised internal temperature too far
Blocked vents or poor airflow around the speed oven
A cooling fan that is slow or stopped
A temperature sensor or control that misreads heat

✓ One safe check you can try

1. Turn the speed oven off and keep the door closed while it cools for an hour. 2. Make sure its vents and the cabinet around it are clear of boxes or trays. 3. Power the oven down at the breaker for a minute and back on. 4. Try a short convection or microwave run. 5. If A1 comes back quickly, call us.

! Why to stop there

A speed oven contains both a microwave system and heating, so overheating needs careful diagnosis.
Repeated overheating can damage the control.
We check airflow, fans and sensors, then explain the cost in writing.
Repairs carry our 30-day workmanship warranty.

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.

A5Fisher & Paykel Speed Oven Alert A5: Microwave System Overheated

A1A1 questions

How is A1 different from A5?

A1 says the oven overall has overheated. A5 says the microwave system itself overheated. Both ask you to let the oven cool, but they point to different parts.

How long should it cool?

Leave it for at least an hour with the door closed. After that, power it down and up. If A1 vanishes, the oven was just reacting to heat.

What if A1 returns after a short cook?

Then something is not cooling the oven properly, such as airflow or a fan. That is the point to call us rather than keep trying.
