How to Repair Common Oven Parts

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

A precise oven thermometer is essential for bakers of all kinds. Knowing how your oven functions will help improve your baking and roasting skills and eliminate those irritated hot spots that can cause havoc with cakes, cookies and other baked items.

Thermostat

The thermostat is an important component of your oven. It helps to ensure that the temperature of food matches the temperature that you set on the control panel. Unfortunately, like any other electronic mechanical switch or sensor it may have issues that cause the oven to over or under heat, or not be able to keep the temperature at the level you've set.

The oven thermostat is an extremely small piece of different metals bonded together. When heated by the oven, the metals expand or flex at different rates. This creates 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 it expands the bimetallic strip in a circuit, re-establishing it and activating the heating element. This process is repeated repeatedly to ensure that the oven remains at a constant temperature.

The oven must be disconnected and all screws removed to identify a thermostat problem. If you have a multimeter (which is a device that measures the electrical current), set it to the ohms setting, and then test the thermostat. If the multimeter reads zero or close to zero, the thermostat is functioning properly and doesn't need to be replaced.

If the multimeter does not read anything then the thermostat is not working properly. It needs to be replaced. Cooker Spare Parts suggests that you replace your thermostat with one of the same model as the one you have. They are available online or at a kitchen remodeling goods store, and are available at a reasonable price.

Bake Element

Ovens aren't complete without the bake element which creates heat to make your oven cook food. It's a simple element that transforms electricity into high temperatures for baking, roasting and broiling. Electric ovens and oven uk ranges usually have heating elements, which are either visible or hidden beneath the floor.

In general oven heating elements comprise of high-resistance elements like nickel-chromium. They convert electricity into heat via resistance. The heat then radiates through the oven's interior to achieve the desired temperature to cook various types of food.

When you turn on the best oven the heating elements start to generate heat by the high-voltage current flowing across the metal's surface. When electricity flows through it the element is heated. The element will turn red hot when it reaches the temperature you want.

The baked element is the primary source of heat in most oven functions. It's typically located at the bottom of the oven and is used for the self-cleaning feature in many automatic oven models. When it begins to get hot, you might find that your oven isn't able to preheat as quickly or that your food isn't cooked through completely.

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 steel against each other on one side of your device. The other end of the baking element against one terminal and place your hand on it. If the element feels warm, take it off it and start testing again. If not, remove it and try again.

Broil Element

The broil element is typically located in the top of your oven's cavity and produces the same high temperature as a grill to brown or char food. Broil settings in ovens are ideal for hob quick sear meat crisp vegetables, heat lasagna or caramelize the topping of a casserole.

The broiler heating element is similar to the bake element in that it converts electrical energy by resistance into heat. It consists of an inner core of wires that are wrapped in insulating perlite product. The core of the element is then covered with an outer layer of stainless steel to protect the wires against direct contact with the oven. The three-layer structure helps reduce the broil element's temperature which makes it safer hobs and ovens more efficient than older styles of elements.

While you can use any heating element in your oven, you should choose one that is in line with the rated wattage of your oven. A different wattage could harm your oven or cause it to overheat. The voltage and current ratings of the new heating elements are available on the control panel of your oven. This allows you to determine the ratings and wattage of your oven.

Verify the resistance of your old element, then compare it to the wattage ratings of the new one. The higher the resistance, the greater the power that an oven element draws from.

If the heating element in your broiler is malfunctioning or isn't working at all, you must replace it as soon as possible. Your oven needs to function properly for you to be able to cook your favourite meals. If your oven does not function at all, or only intermittently, then the issue could be in a different part.

Light Bulb and Assembly

The light lets you monitor your food as it cooks without opening the doors and let the heat escape. The light will also let you know when the casserole is done. It's not uncommon for the bulb to die. This can be very frustrating, but it's a relatively simple fix that you can tackle yourself. Check that the breaker is not tripped, and that the connector has three prongs.

Remove the old bulb and then find the new one. You may have to look online to find a replacement that matches the wattage and type of oven you have. Some appliances use standard 40-watt bulbs some require a halogen bulb that is up to 50 watts. Be aware that the oils from your hands can cause damage to the bulb, so consider using cotton gloves when handling it.

Before putting the new bulb into place, you should first remove it from its glass casing. It is important to take this step slowly to ensure that you don't damage it. Then, you'll need to eliminate the air inside the bulb and fill it up with a mixture of gases. This will prolong the lifespan for the filament.

If your bulb is always blinking, it could be an electrical problem that requires a professional to fix. 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 an excellent idea to unplug your oven and disconnect the power from the outlet before you start any repair. This will prevent you from being shocked by electricity.

Vent Tube

The vent tube is an essential oven part as it allows for a tiny amount of airflow to be created 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 crucial for the proper operation of any electric or gas oven.

Vents in best ovens can get blocked or clogged due to a variety of factors. Accidental spills or splatters while cooking can leave sticky residues on the oven vents, which could attract dust and other debris which can lead to blockages or clogs in the course of time. Grease and oil particles can become airborne and settle around the vents, too. Other environmental factors, such as kitchen construction and renovations, can bring dust or other pollutants into the vents, which can cause clogs or blockages.

Depending on the oven model the vent tube could include an a bottle guide 20 and spreader 46, as well as fill tip 12 that are formed with the pipe 32. For example the bottle guide 20 could have a tapered outer surface that compliments the complementarily tapered inner surface of the spreader 46 to allow the vent tube to be easily inserted into different sizes and shapes of bottle necks.

A blocked or clogged vent tube can cause a loss of pressure within the enclosing structure. This could 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 think your vent pipe may be clogged or blocked. They will diagnose the issue and provide suggestions on how to remove or clean the vent.
