7 Tips To Make The Best Use Of Your Oven
How to Repair Common Oven Parts

The oven is a common kitchen appliance used to cook food. The heat generated by the oven sterilizes food items and kills the majority of micro-organisms present in them.

All bakers need an accurate oven thermometer. Understanding how your oven works will help improve your baking and roasting skills and eliminate those annoying hot spots that wreak havoc with cookies, cakes and other baked goods.

Thermostat

The thermostat is one of the most vital components of your oven, assisting to ensure that the temperature of your food is in line with what you've set in your control panel. As with any electronic mechanical switch or sensor it may have issues that cause the oven to over heat or under heat, or simply not be able to maintain the temperature at the level you've set.

The oven thermostat is basically a small strip made of two different metals connected. When heated, the different metals expand and flex at different rates, forming or breaking an electrical circuit. When the metal in your thermostat reaches the temperature you set on your control panel, it will shut off power to the heater. As the oven cools the bimetallic strips expand, re-establishing circuit and activating the heating element. This cycle continues for a long time to ensure a constant oven temperature.

It is necessary to disconnect the oven and all screws removed to identify the problem with the thermostat. If you own a multimeter (which is a tool that detects electrical current) set it to the ohms setting, and then test the thermostat. If the multimeter reads 0 or very close to it then the thermostat is operating properly and doesn't need to be replaced.

If the multimeter fails to detect anything it means that the thermostat is defective. It needs to be replaced. Cooker Spare Parts recommends that you replace the thermostat with a brand new one of the same type that your old one. These thermostats are available at a reasonable price online or in a kitchen goods shop.

Bake Element

The bake element is crucial for the proper operation of your oven. It provides the heat needed to cook food items. It's a basic component that transforms electricity into the high temperatures needed for baking, roasting and broiling. Heating elements are usually found in electric ranges and ovens, and they can be either uncovered or hidden under the oven's floor.

In general oven heating elements comprise of high-resistance metals such as nickel-chromium. They convert electricity into heat through resistance. This heat then radiates through the interior of the oven to reach the temperature required for cooking different types foods.

When you turn on the oven the heating elements begin to generate heat by the high-voltage current flowing across the metal's surface. The element is a coil or ribbon (straight or corrugated) of wire. When the electric current flows through it, it starts to heat up. When the element reaches its desired temperature it starts to be lit up in red hot.

The baked element is the primary source of heat for most oven functions. It is usually located at lower levels of the oven. Many automatic oven models also utilize it for self-cleaning. If it starts to burn out, you might find that your oven isn't able to heat up as fast or that your food is not fully cooked.

To verify that you have a working oven baking element plug your multimeter into its red and black ports, and then place the probes made of metal against each other on one end of your device. The other end should be placed against one of its terminals and place your hand on it to determine if the element is warm to the touch. If not, remove it and try again.

Broil Element

The broil element, typically located at the top of your cavity, provides high temperatures to brown or char foods. The broil setting of your oven is a great option for quickly grilling meat, crisping vegetables, reheating lasagna or caramelizing the top of the casserole.

Similar to the bake element the broiler heating element transforms electrical energy into heat through the process of resistance. It is composed of an inner core comprised of metal wires, which are wrapped in an insulating, expanded material called perlite. The inner core is wrapped in an outer layer of stainless steel, which protects the wires from direct contact with the oven. The three-layer design can help reduce the temperature of the broil element, making it more secure than the older models.

You can use any heating element to bake or broiling in your oven. However, it is important to choose one that is in line with the wattage of your oven's rating. A different wattage may cause damage to your oven or cause it overheat. You can check the power of your oven and the rating of the new heating element by examining their voltage and current ratings on the control panel of your oven.


Examine the resistance of the previous element, then compare it with the wattage rating of the new element. The greater the resistance, the more the power that an oven element draws from.

Replace your broiler element immediately in the event that it isn't working or is acting up. Your oven needs to function correctly to be able to cook your favorite meals. However, if your oven isn't functioning in any way or only intermittently, the issue may be in a different area of your oven.

Light Bulb and Assembly

The light allows you to monitor the food that is cooking without opening the door and let the heat escape. The light will also inform you when the casserole is finished. But it's not uncommon for the bulb to fail. It can be quite frustrating, but you can do it yourself. Make sure the breaker is not tripped, and that the connector has three prongs.

First, take out the old light bulb and locate the new one. It is possible to look online to find a replacement that matches the wattage and the type of your oven. Some ovens utilize standard appliance bulbs of 40 watts and others require a halogen lamp up to 50 watts. It is recommended to use cotton gloves to shield the bulbs from damage caused by oil.

Remove the glass casing of the bulb before replacing it. It is important to do this slowly to avoid breaking it. Then, you'll need to remove the air from the bulb and fill it up with gas mixture. This will ensure a longer lifespan for the filament.

If your bulb keeps running out it could be an electrical issue that requires an expert to fix it. Verify that you're using the correct oven bulb and check your Use and Care Guide for more troubleshooting advice. And remember that it's always recommended to unplug your oven and disconnect it from the outlet before you begin any repair. This will protect you from electric shock.

Vent Tube

The vent tube is an important oven element because it allows for a small amount of airflow to flow inside the cavity. This allows the bake element to circulate heat throughout the oven, making sure that the temperature is evenly distributed.

It also allows vapors to be released from the oven, and smoke to be drawn from the cooking surface. It is essential for proper functioning of any gas or electric oven.

Vents for ovens can become clogged or blocked by several reasons. Accidental spills or splatters while cooking can leave sticky residues on oven vents, which draw dust and other debris which can lead to obstructions or blockages in the course of time. Grease and oil can also be airborne and settle on vents. Other environmental factors, such as kitchen renovations and construction work, can bring dust or other contaminants into the vents, leading to obstructions or clogs.

Based on the oven model, the vent tube may include an a bottle guide 20, spreader 46 and fill tip 12 that are integrally formed with the pipe 32. For instance, the bottle guide 20 may have a tapered outer surface that compliments the complementarily tapered inside of the spreader 46, allowing the vent tube to be smoothly placed into various sizes and designs of bottle necks.

A blocked vent tube may cause a loss in pressure inside the enclosure, which can lead to an exhaust downdraft, which pulls the exhaust backwards and down the vent, causing damage to oven's components. Consult a professional if suspect that your vent tube may be clogged or blocked. They will determine the cause and offer suggestions for removing or cleaning the vent.
