How to Repair Common Oven Parts Ovens are a common kitchen appliance used to cook food. The heat generated by the oven sterilizes food and kills the majority of microorganisms. An accurate oven thermometer is an 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 cookies, cakes and other baked items. Thermostat The thermostat is an important part of your oven. It assists in ensuring that the temperature of food is in line with 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 not be able to maintain the temperature at what you've set. The oven thermostat is essentially tiny strips of two different metals joined. When heated to a certain temperature, the two metals expand and bend at different rates. This creates an electrical circuit. When the metal in your thermostat reaches the temperature you have set on your control panel, it will shut off the power to the heater. As the oven cools the bimetallic strip expands to re-establish the circuit before activating the heating element. This cycle continues for a long time to ensure that the oven remains at a constant temperature. To determine if there is 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 displays zero or close to zero, the thermostat is functioning correctly and doesn't require to be replaced. If the multimeter does not read anything, then the thermostat is not working properly and requires replacement. 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 the kitchen store, and can be bought at a reasonable price. Bake Element The bake element is crucial to the functioning of your oven. It produces heat that lets it cook food items. It's a small element that converts electricity into the high temperatures required for baking, roasting, and broiling. Heating elements are usually found in electric ranges and ovens and are either uncovered or hidden under the floor of the oven. The majority of oven heating elements are constructed of high-resistance materials such as nickel-chromium alloy. They convert electrical energy into heat through the process of resistance, which radiates outwards into the oven interior to raise the temperature to the desired level to cook different kinds of food items. When you start the oven the heating elements start to produce heat due to the high-voltage current flowing across the surface of the metal. oven hob is a ribbon or coil (straight or corrugated) of wire, and as the electric current passes through it, it begins to get hotter. When the element reaches its desired temperature, it starts to glow red hot. The baked element is the primary source of heat used in most oven functions. It's usually located at the lower levels of the oven. A lot of ovens that are automated also utilize it for self-cleaning. When it begins to burn out, you might notice that your oven doesn't heat up as fast or that your food isn't cooked through completely. To verify that you have a working oven baking element, plug your multimeter into its black and red ports, then touch the probes made of steel against each other on one side of your element. The other end of the element on one terminal and then place your hand on it. If the element feels warm, remove it and start testing again. If it's not, take off the element and start testing again. Broil Element The broil element, which is usually located on the top of your cavity offers high heat to brown or char the food. The broil setting of your oven is an excellent option for quickly searing meat or vegetables, crisping them up, reheating lasagna, or making caramel on top of the casserole. Similar to the bake element the broiler heating element converts electrical energy into heat via the process of resistance. It is comprised of an inner core of metal wires wrapped in insulating perlite material. The inner core of the element is covered with a stainless steel outer layer to shield the wires from direct contact with the oven. The three-layer structure helps reduce the temperature of the broil element, making it more durable and safer than older types of elements. You can use any heating element for baking or broiling in your oven. But, you must choose one that is compatible with the wattage that your oven is rated for. A different wattage may cause damage to your oven or cause it overheat. The voltage and current ratings of the new heating elements can be located on the control panel of your oven. This will allow you to examine the power and rating of your oven. Examine 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. Replace your broiler element immediately If it's not working or if it is acting up. It is crucial that your oven functions correctly to be able to cook all of your favorite food items. If, however, your oven isn't functioning at all or only intermittently, the problem could be in a different area of your oven. Light Bulb and Assembly The oven light lets you keep an eye on your food as it cooks, without opening the door to let heat escape. The light also informs you when your casserole is ready. It's not uncommon for the bulb to go. This can be very frustrating but it's an easy repair that you can do yourself. Before you start, 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 locate the new one. You may have to search the internet for a replacement that matches the wattage and type of oven you have. Some ovens use standard 40-watt appliance bulbs some require a halogen bulb up to 50 watts. Be aware that the oil in your hands can damage the bulb, so consider using cotton gloves when handling it. Remove the glass casing of the bulb before replacing it. You should do this slowly to avoid breaking it. Then, you'll have to eliminate the air inside the bulb and fill it with a mixture of gases. This will provide a longer life for the filament. If your bulb is constantly blinking, it may be a larger electrical problem that needs to be handled by a professional. Verify that you're using the correct oven bulb and consult your Use and Care Guide for more help in troubleshooting. 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 an important 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 throughout the oven and ensures the temperature is evenly dispersed. It also allows the vapors be released from the oven, and smoke to be drawn from the cooking surface. It is essential for the proper operation of any gas or electric oven. Vents for ovens can become blocked or blocked due to several reasons. Accidental spills and splatters during cooking can leave sticky residues on oven vents, which can attract dust and other debris that could eventually cause clogs or blockages in the course of time. Oil and grease particles can be blown into the air and settle around the vents, too. Other environmental factors, such as kitchen renovations and construction work could introduce dust or other contaminants into the vents, resulting in obstructions or clogs. Based on the type of the oven, the vent tube can comprise a spreader 46 and the fill tip 12, and an a bottle guide 20 that are integrally formed into the pipe 32. The bottle guide 20 can have a tapered edge that is complemented by the tapered inner edge of the spreader. This allows the vent tubes to slide smoothly into different sizes and shapes of bottle necks. A clogged or blocked vent tube can cause an increase in pressure within the structure that surrounds it, which can result in a downdraft that pushes exhaust down the vent and backwards towards the oven burners, causing damage to the oven components. Contact a professional if you think your vent pipe may be clogged or blocked. They will identify the problem and offer suggestions on how to remove or clean the vent.
