How it shows up ## What people describe when they call - “One side or one shelf browns faster” - “Everything takes longer than the recipe says” - “It crept up rather than failing suddenly” In more detail ## About Fisher & Paykel oven baking unevenly ### The fastest diagnosis is the code Bake a tray of something uniform — plain scones or slices of bread — on one shelf and look at the pattern. Front-to-back unevenness points at the door seal and the airflow; side-to-side points at an element or the convection fan; and everything uniformly pale or dark points at calibration and the sensor. That one test tells us more than any description. ### The pattern is the diagnosis **Front to back**: airflow and the door seal. **Side to side**: an element or the convection fan. **Uniformly pale or dark**: calibration, which means the temperature sensor. One tray of something uniform tells you which, and it costs the price of a bag of flour. ### Why the sensor comes first Because it **drifts before it fails**. An oven reading a few percent low still heats, still looks healthy, still passes every casual test, and browns badly for a year. It is also the cheapest part on the page, which is a good combination for you. ### What is not a repair Two crowded trays, a heavy dark pan, foil laid on a shelf, or a rack in the wrong position. We would rather tell you that than sell you an element, and the uniform-tray test is what distinguishes them. This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about fisher & Paykel oven baking unevenly It can be, and we would rather you tested that first. Ovens do not all behave identically, and a new pan, a change of shelf or a heavier tray shifts results without anything failing. The uniform-tray test settles it: a genuine unevenness shows the same pattern every time, in the same place. That is calibration rather than unevenness, and it is usually the temperature sensor drifting. It is the cheapest part on the oven pages and the commonest cause of “it is not what it used to be”. An oven thermometer for a few dollars will confirm it before you call. Then look at the convection side specifically: the fan, and the element that sits behind it on machines that have one. An oven whose conventional bake is fine and whose convection is not has told you exactly where to look.
