How to Repair Common Oven Parts The oven is an appliance in the kitchen that is commonly used to cook food. The heat generated by the oven sterilizes food and kills most of the micro-organisms in them. All bakers need an accurate oven thermometer. Knowing how your oven functions will help improve your baking cooking, roasting and cooking abilities. It will also eliminate those annoying hot spots which can ruin cookies, cakes and baked items. Thermostat The thermostat is a crucial element of your oven. It assists in ensuring that the temperature of food corresponds to the temperature you set on the control panel. It could be a problem as with any other sensor or switch that is electro-mechanical. The oven may overheat or underheat, or not keep the temperature you set. The oven thermostat is tiny strips of two different metals bonded together. When heated by the oven, the metals expand and bend 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 the power to the heater. As the oven cools the bimetallic strip expands in a way, reestablishing the circuit and turning on the heating element. This cycle continues for a long time to ensure that the oven remains at a constant temperature. To identify a problem with the thermostat, you'll need to unplug the oven and ensure that all screws holding it in place have been removed. Set your multimeter to the Ohms setting and then test the thermostat. If the multimeter reads zero or close to it, then the thermostat is working correctly and doesn't require to be replaced. If the multimeter isn't reading anything at all, then the thermostat is faulty and needs to be replaced. Cooker Spare Parts recommends that you replace the thermostat with a new one of the same type as the one you have. The thermostats are available for purchase at a reasonable price online or at a kitchen goods shop. Bake Element The bake element is crucial to the operation of your oven. It provides the heat needed to cook food items. It's a simple element that converts electricity into high temperatures for baking, roasting, and broiling. Electric ovens and ranges usually include heating elements that can be exposed or hidden beneath the floor. In general oven heating elements are made up of high-resistance metals such as nickel-chromium. They work by converting electrical energy into heat through the process of resistance which then radiates throughout the oven's interior, causing it to increase the temperature to the desired temperature to cook different kinds of food. When you turn on your oven, the heating element begins to produce heat through the high-voltage electricity moving across its metal surface. The element is a ribbon or coil (straight or corrugated) of wire. When the electric current flows through it, it starts to heat up. The element will appear red hot when it is at the desired temperature. The baked element is the main source of heat in most oven functions. It's usually located in the bottom of the oven and is also used to clean the oven in many automatic oven models. When it starts to get hot, you might be noticing that your oven doesn't warm as quickly or your food is not cooked through completely. Connect your multimeter to its black and red ports. Then, touch the probes made of metal on one side of the element to each other. The other end of the element on one terminal and place your hands on it. If the element feels warm, take it off it and try testing it again. If not, take it off and try again. Broil Element The broil element is usually situated in the top of the oven cavity and provides high heat like grills to brown or char food. The oven's broil setting is an excellent way to quickly cook meat, crisp vegetables, reheat lasagna or caramelize the topping of a casserole. The broiler heating element is comparable to the bake element in that it converts electrical energy through resistance into heat. It is made up of an internal core of metal wires wrapped in an insulating expanded perlite material. The inside of the element is covered with a stainless steel outer layer to protect the wires against direct contact with the oven. The three-layer design helps reduce the temperature of the broil element, making it more secure than older styles. While you are able to use any heating element in your oven, make sure to select one that is compatible with the wattage rating of your oven. A different wattage may harm your oven, or cause it to overheat. The current and voltage ratings of the latest heating elements are available on the control panel of your oven. This allows you to determine the wattage and rating of your oven. You should also test the resistance of your previous element and compare it to the power of the new broiler heating element. The higher the resistance of an oven element, the more power it uses. Replace the element in your broiler immediately if it is not working or is acting up. Your oven must function properly to be able to cook your favourite meals. If your oven does not function 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 door and let the heat escape. The light also informs you when the casserole is ready. However, it's not uncommon for the bulb to go out. It can be a hassle however, it's an easy fix you can tackle yourself. Before you begin, be sure that the breaker hasn't been tripped and that the three-prong connector is intact. First, remove the light bulb that was in use and locate the new one. You may need to search online to find the correct replacement bulb that is compatible with your oven's wattage. Some use standard 40-watt appliance bulbs and others require halogen bulbs up to 50 watts. It is recommended to use cotton gloves to shield the bulbs from damage caused by oil. Before you put the new bulb in place, you should first remove it from its glass casing. Do slowly to avoid breaking it. You'll then need to remove the air from the bulb and replace it with an appropriate mixture. This ensures a longer life for the filament. If your bulb is constantly being replaced, it may be a larger electrical issue that should be dealt with by a professional. Make sure that you're using the correct bulb for your oven, and look over your Use and Care Guide for more troubleshooting advice. Be sure to unplug your oven and shut off the power prior to beginning any repairs. This will prevent you from being shocked by electricity. Vent Tube The vent tube is a crucial oven component because it allows a small amount of airflow to be created inside the cavity. This allows the bake element to circulate heat throughout the oven, ensuring that the temperature is evenly dispersed. hob allows the vapors be released from the oven, and smoke to be drained from the cooking surface. It is essential for efficient operation of any electric or gas oven. Oven vent tubes can become blocked or blocked due to several factors. Accidental spills or splatters while cooking can leave sticky residues on the oven vents, which attract dust and other debris that can eventually cause clogs or blockages in the course of time. Grease and oil can also become airborne and settle on vents. Other environmental factors, like kitchen and construction projects can cause dust to enter the vents. This can lead to clogs. Based on the oven model, the vent tube may comprise an a bottle guide 20, spreader 46 and fill tip 12 that are integrally constructed with the pipe 32. For instance the bottle guide 20 may have a tapered exterior surface which is in harmony with the tapered inside of the spreader 46. This allows the vent tube to be easily inserted into different sizes and designs of bottle necks. A blocked or clogged vent tube could cause the loss of pressure inside the enclosing structure, which can create a downdraft situation that pushes exhaust down the vent and then backwards over the oven's burners, causing damage to oven components. If you suspect that the vent tube in your oven is clogged or blocked, contact a professional for help. They will determine the cause and offer suggestions for removing or cleaning the vent.
