How to Repair Common Oven Parts The oven is a kitchen appliance that is commonly used to cook food. The heat from the oven sterilizes food and kills the majority of microorganisms. All bakers need an accurate oven thermometer. Knowing how your oven functions will help improve your baking and roasting skills, and eliminate those frustrating hot spots that cause havoc with cookies, cakes and other baked goods. Thermostat The thermostat is an essential element of your oven. It helps to ensure that the temperature of food matches the temperature that you set on the control panel. However, just like any other electro mechanical switch or sensor it can sometimes have problems that result in the oven going over or under heat, or simply not be able to maintain the temperature at the level you've set. The oven thermostat is essentially tiny strips of two different metals bonded together. When heated the different metals expand and bend at different rates, creating or breaking an electrical circuit. When the metal in your thermostat reaches the temperature you set on the control panel it will shut off the heating element's power. As the oven cools the bimetallic strip contract in a way, reestablishing the circuit and activating the heating element. This process is repeated over and over to maintain a constant temperature in your oven. It is necessary to disconnect the oven and all screws removed to identify a thermostat problem. If you have a multimeter (which is a tool that detects electrical current) set it to the ohms level and then test the thermostat. If the multimeter reads zero or very close to it the thermostat is operating properly and doesn't need to be replaced. If the multimeter doesn't read anything, the thermostat is faulty. It is time to get it replaced. Cooker Spare Parts suggests that you replace your thermostat with one of the same model as the one you have. They can be purchased through the internet or at an appliance store and are available at a reasonable cost. Bake Element The bake element is vital for the proper operation of your oven. It generates the heat needed to cook food. It's a simple element that converts electricity into high temperatures 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 are made up of high-resistance materials like nickel-chromium. They convert electrical energy into heat through the process of resistance which radiates outwards into the oven's interior, causing it to increase the temperature to the desired level for cooking different types of foods. When you turn on your oven the heating element gets to generate heat from the high-voltage electrical energy moving across its metal surface. When electricity flows through it the element is heated. When the element reaches its temperature it begins to glow red hot. The baked element is the primary source of heat in most oven functions. It's usually located at the bottom of the oven. A lot of ovens that are automated also have it for self-cleaning. You might be noticing that the oven doesn't warm up as quickly or that your food isn't fully cooked. To determine if you have a functioning oven baking element connect your multimeter to its red and black ports, then rub the metal probes against each other on one end of the element. Place the other end against one of its terminals and then place your hands on it to test if the element is warm to the contact. If not, take it off and try again. Broil Element The broil element is typically located in the top of the oven's cavity and produces the same high temperature as grills to brown or char food items. Broil settings in ovens are ideal for quick sear meat, crisp vegetables, reheat 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 is comprised of an inner core of wires made of metal wrapped in insulating expanded perlite material. The core of the element is 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, making it safer and more efficient than the older designs of elements. You can use any heating element you want to use for baking or broiling in your oven. But, you must choose one that is in line with the wattage of your oven's rating. A different wattage could damage your oven or cause it to overheat. You can verify the power of your oven and the rating of the new heating element by looking at their voltage and current ratings on the control panel of your oven. Check the resistance of the previous element, and compare it to the wattage ratings of the new element. The greater the resistance, the more the power that an oven element draws from. If the heating element in your broiler is not working or functions in any way, you should replace it as soon as possible. Your oven must function properly for you to be able to cook your favourite meals. If, however, your oven isn't working at all or only intermittently, the issue could be with a different part of your oven. Light Bulb and Assembly The oven light helps keep an eye on your food cooking without having to open the door to let heat escape. The light will also let you know when the casserole has been cooked. But it's not uncommon for the light bulb to go out. This can be very frustrating however, it's an simple fix that you can accomplish yourself. Before you begin, make sure that the breaker hasn't been tripped and that the three-prong connector is in good condition. Remove the old bulb and then find the new one. You may have to search the internet for a replacement that matches the wattage and type of your oven. Some use standard 40-watt appliance bulbs, while others require a halogen bulb that is up to 50 watts. Be ovens uk that the oil in your hands could damage the halogen bulb, so you should use cotton gloves when handling it. Remove the glass casing of the bulb prior to replacing it. Do this slowly to avoid breaking it. You'll have to remove the air from the bulb and replace it with the mixture. This will extend the lifespan for the filament. If your light bulb is always being replaced, it could be a wider electrical problem that needs to be handled by a professional. Be sure to double check that you're using a correct bulb for your oven and look over your Use and Care Guide for more troubleshooting advice. Remember that it's an excellent idea to unplug your oven and disconnect it from the outlet prior to you start any repair. This will protect you from electrical shock. Vent Tube The vent tube is an important oven component that permits a small airflow inside the cavity. This allows the bake-element to circulate heat throughout the oven, ensuring that the temperature is evenly distributed. 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 necessary for the proper operation of any gas or electric oven. Vents for ovens can become blocked or blocked due to several reasons. Accidental spills or splatters could leave sticky residues in oven vents. These can attract debris, dust and other contaminants that could cause clogs over time. Oil and grease particles can be blown into the air and settle around the vents, too. 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 and spreader 46, as well as fill tip 12 that are constructed with the pipe 32. For example, the bottle guide 20 might have a tapered outer layer which is in harmony with the tapered inner surface of the spreader 46, allowing the vent tube to be easily placed into various sizes and forms of bottle necks. A blocked vent tube may cause a reduction in pressure within the enclosure, which can lead to a downdraft that pulls exhaust backwards and down the vent, causing damage to the oven components. Consult a professional if believe that your vent could be blocked or clogged. They will identify the issue and give suggestions for clearing or cleaning the vent.
