How to Repair Common Oven Parts The oven is an appliance in the kitchen that is used to cook food. Click Webpage generated by the oven sterilizes food and kills the majority of microorganisms. Every baker needs an accurate oven thermometer. Understanding how your oven functions will help improve your baking cooking, roasting and cooking abilities. It will also help eliminate those annoying hot spots which can ruin cakes, cookies and baked goods. Thermostat The thermostat is a crucial component of your oven. It is used to ensure that the temperature of food matches the temperature that you set on the control panel. However, just like any other electronic mechanical switch or sensor it can sometimes have problems that cause the oven to over heat or under heat, or just not be able to maintain the temperature you've set. The oven thermostat is basically tiny strips of two different metals that are connected. When heated by the oven, the metals expand and bend at different rates. This creates an electrical circuit. When the metal in the thermostat is at 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 in a circuit, re-establishing it and activating the heating element. This process is repeated repeatedly to ensure a constant oven temperature. The oven must be disconnected and all screws removed in order to determine the problem with the thermostat. If you own a multimeter (which is a device that measures the electrical current), set it to the ohms level and then test the thermostat. If the multimeter displays zero or close to zero, the thermostat is functioning correctly and does not need to be changed. If the multimeter doesn't detect anything it means that the thermostat is defective. It needs to be replaced. Cooker Spare Parts recommends that you replace the thermostat with a fresh one of the same type as the one you have. These thermostats are available at a reasonable price online or in a kitchen products shop. Bake Element The bake element is vital to the functioning of your oven. It produces heat that lets it cook food items. It's a simple component that transforms electricity into high temperatures for baking, roasting, and broiling. Electric ovens and ranges typically include heating elements that can be exposed or hidden beneath the floor. Generally, oven heating elements are made of high-resistance materials such as nickel-chromium alloy. They work by converting electrical energy into heat via the process of resistance, which then radiates throughout the oven's interior, causing it to increase the temperature to the desired level to cook various types of food. When you switch on the oven, the heating elements begin to produce heat due to the high-voltage electric current flowing across the metal surface. When electric current runs through it the element is heated. When the element reaches its temperature it begins to be lit up in red hot. The baked element is the main source of heat for the majority of oven functions. It is usually located at bottom of the oven. Many automatic oven models also use it for self-cleaning. 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. To determine if you have a functioning oven baking element plug your multimeter into its black and red ports, and then place the probes made of metal against each other on one end of your device. Place the other end of the element on one terminal and then place your hand on it. If the element feels warm, remove it and test it again. If not, remove it and try again. Broil Element The broil element is typically located at the top of your oven's cavity and produces high heat like grills to brown or char food. The broil setting of your oven is a great option for quickly searing meat and vegetables, crisping up vegetables, warming lasagna or making caramel on top of a casserole. The broiler heating element has a similarity to the bake element in that it converts electrical energy via resistance into heat. It is composed of an inner core consisting of metal wires, wrapped in an insulating expanded product called perlite. The inside of the element is covered with a stainless steel outer layer to shield the wires from direct contact with the oven. The three-layer design can help lower the temperature of the broil element, making it safer than older styles. You can use any heating element you want to use for baking or broiling in your oven. However, you should select one that matches the wattage of your oven's rating. A different wattage can damage your oven, or cause it to overheat. The voltage and current ratings of the latest heating elements can be found on the control panel of your oven. This allows you to determine the wattage and rating of your oven. It is also advisable to check the resistance of your previous element and compare it to the power output of your new broiler heating element. The greater the resistance, the greater the power that an oven element draws from. Replace the broiler element as soon as possible in the event that it isn't functioning or if it's acting up. It is essential for your oven to function correctly to be able to cook all your favorite foods. If your oven doesn't function in any way, or just intermittently, then the issue could be a problem with a different component. Light Bulb and Assembly The oven light helps you keep an eye on your food while it cooks without opening the door to let heat escape. The light also alerts you when the casserole is ready. It's not uncommon for the bulb to die. It can be quite frustrating, but you can do it yourself. Before you begin, be sure that the breaker isn't tripped and that the three-prong connector is in good condition. Remove the old bulb, and then look for the new bulb. It is possible to search online for a replacement that matches the wattage and type of your oven. Some ovens use standard appliances with bulbs that run at 40 watts some require a halogen lamp up to 50 watts. It is recommended to use cotton gloves to protect the halogen bulbs from the damage caused by oil. Before you place the new bulb in place it is important to first remove it from its glass casing. You should do this slowly to avoid breaking it. Then, you'll need to remove the air from the bulb and replace it with the mixture. This will ensure a longer lifespan for the filament. If your bulb keeps going out, there may be a larger electrical problem that needs to be handled by an expert. Make sure you double-check that you're using the right bulb for your oven and look over your Use and Care Guide for more troubleshooting advice. And remember that it's always an excellent idea to unplug your oven and disconnect it from the outlet prior to you start any repair. This will help prevent being shocked by electricity. Vent Tube The vent tube is an important oven component that permits a tiny airflow inside the cavity. This allows the bake element to circulate heat throughout the oven, ensuring that the temperature is evenly dispersed. It also allows vapors to be released from the oven, and smoke to be drained from the cooking surface. It is vital for the proper operation of any electric or gas oven. Vents in ovens can get blocked or blocked due to several reasons. Accidental spills or splatters while cooking can leave sticky residues on the oven vents, which can attract dust and other particles that could eventually cause obstructions 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 work can introduce dust into 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 instance, the bottle guide 20 could have a tapered outer surface that is complemented by the tapered inside of the spreader 46, allowing the vent tube to be effortlessly fitted into various sizes and shapes of bottle necks. A clogged or blocked vent tube can cause the loss of pressure inside the structure that surrounds it, which could result in a downdraft that pulls exhaust down the vent and backwards through the oven's burners, causing damage to oven components. If you suspect that your vent tube is clogged or blocked, consult a professional for help. They will determine the cause and provide recommendations for removing or cleaning the vent.
