Symbol (Icon Description) Official Name What It Means And When To Use It
Single horizontal line at the top and bottom Conventional Heat Uses top and bottom heating elements without a fan. Perfect for traditional baking and roasting where even, gentle heat is key.
Fan symbol inside a circle Fan Oven / True Fan Cooking The fan circulates air heated by an element around it, giving you an even temperature throughout. Ideal for batch baking on multiple shelves.
Zig-zag line at the top Grill Activates the top heating element for intense, direct heat. Use it for grilling sausages, browning a pasta bake, or making toast.

Decoding the Main Functions

To help you get confident with your oven, let’s break down the three main cooking principles these symbols represent.

  • Conventional Heating: This is your classic oven setting, using static heat from elements at the top and bottom. It’s ideal for traditional baking where a steady temperature is needed.
  • Fan-Assisted Cooking (Convection): A fan circulates hot air, which cooks food faster and more evenly. It’s brilliant for baking multiple trays at once.
  • Grilling: This function uses intense, direct heat from the top element. It’s designed for browning, crisping, and quickly cooking thinner cuts of food.

Standard Cooking And Baking Symbols Explained

Getting to grips with your oven’s core symbols is key to mastering everyday cooking. These icons represent foundational heating methods that most recipes rely on.

Conventional Heat For Traditional Bakes

The conventional heat symbol (two parallel horizontal lines) switches on the top and bottom heating elements without a fan. This creates a natural convection process where heat rises from the bottom and radiates from the top. This method is ideal for dishes that need steady, gentle heat, like delicate cakes.

This is your go-to setting for single-shelf cooking. Remember that heat rises, so the top of the oven will be the hottest spot.

Bottom Heat For Crispy Bases

Indicated by a single horizontal line at the bottom, the bottom heat only setting activates just the lower heating element. This directs heat upwards from the base, making it perfect for achieving a crisp and golden-brown underside. It’s the secret to avoiding the dreaded "soggy bottom" and is handy for blind baking pastry.

Top Heat For Browning And Finishing

The top heat only symbol, a single horizontal line at the top, uses only the upper heating element. It provides intense, direct heat from above, similar to a grill but less fierce. It's not for cooking dishes from scratch, but for finishing them. Use it to melt cheese on a pasta bake or brown the top of a gratin.

Mastering Fan And Convection Oven Symbols

Fan-assisted cooking is a standard feature on most modern ovens, promising quicker cooking times and more even results. Getting these icons right is key to unlocking your oven’s full potential. Fan cooking works by circulating hot air, eliminating hot spots and ensuring a consistent temperature on every shelf. As a result, food cooks approximately 25% faster than in a conventional oven, and you can usually lower the temperature by about 20°C.

The True Fan Cooking Symbol

The most common fan symbol is a fan inside a circle. This represents 'True Fan' cooking. Unlike basic fan-assisted settings, this function uses its own dedicated heating element wrapped around the fan. This creates the most uniform heat possible, making it the best choice for multi-shelf cooking, such as batch baking biscuits.

Fan With Bottom Element

A symbol showing a fan above a single horizontal line combines the fan with the bottom heating element. This is a specialist function for dishes that need a crisp base without overcooking the top. The fan circulates the intense heat from the bottom, ensuring the entire dish cooks evenly. It's the secret to a professional-quality pizza at home.

The Fan Grill Symbol

Combining the grill with the fan, this symbol usually shows a zigzag line above a fan. This powerful setting circulates the intense heat from the grill, creating a rotisserie-like effect. It’s perfect for cooking thicker cuts of meat that need to be cooked through while developing a crispy exterior, as it seals in juices beautifully.

Decoding Grill And Browning Symbols

The grill is your oven's secret weapon for achieving a perfect finish. Grill symbols, usually shown as zigzag lines, mean intense, direct heat is coming from the top.

Full Grill and Half Grill Symbols

Your oven may have one or two grill symbols, giving you control over the grilling area.

  • Full Grill (Double Zigzag Line): This activates the entire grilling element. Use it when grilling a tray of sausages or browning a large gratin.
  • Half Grill (Single Zigzag Line): This heats only the central part of the grill element. It's an energy-saving option for smaller portions.

Fan Assisted Grill

The fan assisted grill (a zigzag line above a fan) is a powerful combination that gives a rotisserie-style effect. It pairs the fierce heat of the grill with circulating air, spreading heat evenly. This function is perfect for thicker items like chicken portions or pork chops that need to cook through without burning.

A crucial safety note: always check your oven's manual to see if you should grill with the door open or closed. Some models require the door to be ajar to prevent overheating.
