How to Repair Common Oven Parts The oven is an appliance in the kitchen that is used to cook food. The heat from the oven sterilizes foods and kills the majority of micro-organisms in them. An accurate oven thermometer is essential for bakers of all kinds. Understanding how your oven works can help you improve your baking and roasting skills and eliminate those frustrating hot spots that cause havoc with cakes, cookies and other baked products. Thermostat The thermostat is an important component of your oven. It helps to ensure that the temperature of food matches the temperature you set on the control panel. However, just like any other electro mechanical switch or sensor, it may have issues that result in the oven going over or under heat, or simply not be able to keep the temperature you've set. The oven thermostat is basically an extremely small strip of two different metals that are bonded together. When exposed to heat, the various metals expand and contract at different rates, creating or breaking an electrical circuit. When the thermostat's metal reaches the temperature you've set on your control panel it turns off the heating element's power. 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. To identify a problem with the thermostat you'll need to unplug the oven and make sure that all of the screws that hold it in place have been removed. Set your multimeter 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 properly and doesn't need to be replaced. If the multimeter doesn't read anything then the thermostat is not working properly. It needs to be replaced. Cooker Spare Parts recommends that you replace the thermostat with a new one of the same kind as the one you have. They can be purchased through the internet or at a kitchen goods store, and are available at a reasonable price. Bake Element The bake element is vital to the functioning of your oven. It provides heat that allows it to cook food. It's a simple element that converts electricity into high temperatures for baking, roasting and broiling. Electric ovens and ranges typically have heating elements, which can be exposed or hidden under the floor. In general, oven heating elements consist of high-resistance elements such as nickel-chromium. They work by converting electrical energy into heat by the process of resistance, which radiates outwards into the oven's interior to raise the temperature to the desired temperature to cook different kinds of foods. When you switch on your oven the heating element gets to produce heat through the high-voltage electricity that flows across its metallic surface. The element is a coil or ribbon (straight or corrugated) of wire, and when the electric current flows through it, it begins to increase in temperature. The element will turn red hot when it reaches the temperature you want. The baked element is the primary source of heat for the majority of oven functions. It's typically located at the bottom of the oven and is used to clean the oven in a variety of ovens that are automatic. When it starts to burn out, you might be noticing that your oven doesn't preheat as quickly or that your food is not fully cooked. Connect your multimeter to its red and black ports. Then, you can press the metal probes on one side of the device against each other. Place the other end of the baking element against one terminal and place your hands on it. If ovens and hobs uk feels warm, take it off it and test it again. If it's not, take off 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 food items. The oven's broil setting is an excellent way to quickly sear meat, crisp vegetables, reheat lasagna, or caramelize the topping of the casserole. Similar to the bake element, the broiler heating element transforms electrical energy into heat by the process of resistance. It consists of an inner core of metal wires wrapped in insulating expanded perlite material. The inner core is then encased in an outer layer of stainless steel, which protects the wires from direct contact with the oven. The three-layer structure helps lower the broil element's temperature, making it more secure and efficient than older styles of elements. You can use any heating element to bake or broiling in your oven. However, you should choose one that is in line with the wattage that your oven is rated for. A different wattage can cause damage to your oven or cause it overheat. You can verify 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. It is also advisable to check the resistance of your previous element and compare it with the wattage of your new broiler heating element. The higher the resistance, the greater power an oven element uses. Replace the element in your broiler immediately If it's not working or if it is acting up. It is essential for your oven to function properly to cook your most loved food items. If your oven does not work at all, or only intermittently then the problem may be a problem with a different component. 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 also lets you know when the casserole is ready. However, 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 is not tripped and that the connector has three prongs. First, remove the old light bulb and find the new one. best ovens and hobs uk is possible to search online for a replacement that matches the wattage and the type of your oven. Some ovens use standard appliance bulbs that run at 40 watts some require an halogen lamp that can reach 50 watts. Be aware that the oil from your hands could damage the bulb, so you should use cotton gloves when handling it. Before you put the new bulb into place, you should first remove it from its glass casing. It's crucial to do this slowly so that you don't break it. You'll then need to remove the air from the bulb and replace it with a mixture. This ensures a longer life for the filament. If your bulb is constantly being replaced, it may be a larger electrical issue that must be dealt with by an expert. Make sure you're using the correct oven bulb and look over your Use and Care Guide for additional troubleshooting tips. Make sure to unplug the oven and shut off the power prior to beginning any repairs. This will help prevent getting an electric shock. Vent Tube The vent tube is a crucial oven part as it allows for a tiny amount of airflow to be created within the cavity. This allows the bake element to circulate heat around the oven, ensuring that the temperature is evenly dispersed. It also allows the vapors that are released from the oven to escape, and also allows smoke to be removed from the cooking surface. It is crucial for the efficient operation of any electric or gas oven. Vents for ovens can become blocked by a variety of factors. Accidental spills or splatters could leave sticky remnants in oven vents. They can draw in dust, debris and other contaminants that can cause blockages in the course of time. Grease and oil can also be airborne and then settle on vents. Other environmental factors like kitchen and construction work can create dust in the vents. This can cause clogs. Based on the oven model the vent tube may include a bottle guide 20, spreader 46 and fill tip 12 that are integrally formed with the pipe 32. For example, the bottle guide 20 may have a tapered exterior surface that is complemented by the tapered inside of the spreader 46 to allow the vent tube to be effortlessly placed into various sizes and shapes of bottle necks. A blocked or clogged vent tube can result in the loss of pressure inside the enclosing structure. This can result in a downdraft which pulls exhaust down vent and backwards towards the oven burners, causing damage to the oven's components. If you believe that your vent tube is blocked or blocked, consult an expert for assistance. They will determine the cause and offer suggestions on how to clear or clean the vent.
