How to Repair Common Oven Parts

The oven is an appliance used in kitchens that is commonly used to cook food. The heat produced by the oven sterilizes foods and kills most of the micro-organisms present in them.

Every baker needs an accurate oven thermometer. Understanding how your oven works will help improve your baking hob and oven roasting skills and eliminate those irritated hot spots that can cause havoc with cookies, cakes and other baked goods.

Thermostat

The thermostat is among the most important parts of your oven, helping ensure that the temperature of your food is exactly the temperature you've set on your control panel. It could be a problem as is any other switch or sensor that is electro-mechanical. The oven could overheat or underheat, or not keep the temperature you set.

The oven thermostat is basically an extremely small strip of two different metals that are bonded together. When heated, the metals expand and bend at different rates. This creates an electrical circuit. When the thermostat's metal attains the temperature you've set on the control panel, it shuts off the power to the heating element. As the oven cools it expands the bimetallic strip to re-establish the circuit before turning on heating element. This cycle is repeated continuously to maintain a constant oven temperature.

It is necessary to disconnect the oven and all screws removed to diagnose the problem with the thermostat. If you have a multimeter (which is a device that analyzes the electrical current) set it to the ohms setting and then test the thermostat. If the multimeter displays zero or close to zero it means that the thermostat is working correctly and doesn't require to be changed.

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

Bake Element

Ovens are not complete without the bake element, which is the element that heats up to help your oven cook food. It's a simple component that transforms electricity into high temperatures for baking, roasting, and broiling. Electric ovens and ranges usually include heating elements that are either visible or hidden under the floor.

In general, oven heating elements consist of high-resistance materials such as nickel-chromium. They work by converting electrical energy into heat via the process of resistance which then radiates throughout the oven interior to raise the temperature to the desired degree to cook various types of food.

When you turn on your oven the heating element starts to produce heat through the high-voltage electricity flowing across its metal surface. When the electric current runs through it the element gets heated up. The element will turn red hot when it reaches the desired temperature.

The baked element is the primary source of heat for the majority of oven functions. It is typically located at the lower levels of the oven. A lot of ovens that are automated also utilize it to clean themselves. You might observe that the oven does not heat up as quickly, or that your food hasn't been cooked to perfection.

To determine if you have a functioning oven baking element, plug your multimeter into its red and black ports, then rub the probes made of metal against each other on one side of your element. Place the other end of the element on one terminal and place your hand on it. If the element feels warm, remove it and test it again. If it's not, remove the element and start testing again.

Broil Element

The broil element, typically located at the top of your cavity provides high temperatures to brown or char the food. The oven's broil setting is a great way to quickly cook meat crisp vegetables, heat lasagna or caramelize the top of the casserole.

Similar to the bake element, the broiler heating element converts electrical energy into heat via the process of resistance. It is made up of an inner core consisting of wires made of metal, encased in an insulating and expanded product known as perlite. The inner core is wrapped in an outer layer of stainless steel to protect the wires from direct contact with the oven. The three-layer structure reduces the temperature of the broil element, making it more durable and safer than older styles of elements.

You can use any heating element to bake or broiling in your oven. But, you must choose one that is in line with the wattage that your oven is rated for. A different wattage could cause damage to your oven or cause it overheat. You can determine the wattage of your oven hob and oven the rating of the new heating element by examining their current and voltage ratings on the oven's control panel.

You should also check the resistance of your previous element and compare it with the wattage of your new broiler heating element. The higher the resistance, the more the power that an oven element draws from.

If your broiler's heating element is malfunctioning or isn't working at all, you should replace it immediately. It is essential for your oven to function properly to cook all your favorite food items. If your oven isn't working in any way or only intermittently, the issue could be in a different area of your oven.

Light Bulb and Assembly

The oven hob light helps you keep an eye on your food cooking without opening the door to let heat escape. The light also lets you know when the casserole is ready. It's not uncommon for the light bulb to go out. This can be frustrating however, it's an easy repair that you can tackle yourself. Make sure the breaker isn't tripped and that the connector has three prongs.

First, remove the light bulb that was in use and locate the new one. You may need to look online for a replacement bulb that matches the wattage and type of oven you have. Some use standard 40-watt appliance bulbs, while others require a halogen bulb up to 50 watts. Be aware that the oil from your hands can damage the bulb, so consider using cotton gloves when handling it.

Remove the glass casing of the bulb prior to replacing it. Do slowly to avoid breaking it. Then, you'll need to remove the air from the bulb and replace it with a mixture. This will ensure a longer lifespan of the filament.

If your bulb keeps blinking, it could be a wider electrical issue that must be addressed by a professional. Double check that you are using the correct oven bulb and look over your Use and Care Guide for more troubleshooting advice. Make sure to unplug the oven and shut off the power before beginning any repairs. This will keep you from suffering an electric shock.

Vent Tube

The vent tube is a vital oven component that permits a tiny airflow inside the cavity. This allows the bake element to circulate heat around the oven, ensuring that the temperature is evenly distributed.

It also allows vapors to escape from the oven, and smoke to be drawn from the cooking surface. It is vital for the efficient operation of any gas or electric oven.

Vents in ovens can get blocked by a variety of factors. Accidental spills or splatters may leave sticky remnants in oven vents. They may draw in dust, debris and other contaminants that can cause obstructions in the course of time. Grease and oil particles may be blown into the air and settle around the vents, as well. Other environmental factors, such as kitchen renovations and construction work can bring dust or other contaminants into the vents, which can cause clogs or blockages.

Based on the oven model the vent tube may include an a bottle guide 20 or spreader 46 as well as a fill tip 12 that are constructed with the pipe 32. For instance the bottle guide 20 could have a tapered exterior surface that compliments the complementarily tapered inside of the spreader 46 to allow the vent tube to be effortlessly inserted into different sizes and forms of bottle necks.

A clogged or ovens Uk blocked vent tube can cause a loss of pressure within the structure that surrounds it, which can result in a downdraft that pushes exhaust down the vent and then backwards over the oven's burners, which can cause damage to oven components. Contact a professional if you suspect that your vent tube might be blocked or clogged. They will diagnose the issue and make recommendations on how to clear or baking clean the vent.
