How to Repair Common Oven Parts The oven is a kitchen appliance that is typically used to cook food. The heat from the oven sterilizes food and kills the majority of microorganisms. A precise oven thermometer is essential for bakers of all kinds. Knowing how your oven functions will help improve your baking and roasting skills, and eliminate those annoying hot spots that can cause havoc with cookies, cakes and other baked items. Thermostat The thermostat is an essential element of your oven. It is used to ensure that the temperature of food corresponds to the temperature that you set on the control panel. It can be problematic as with any other sensor or switch that is electro-mechanical. The oven could overheat or underheat, or simply not maintain the temperature you set. The oven thermostat is basically a small strip made of two different metals connected. When heated by the oven, the metals expand or flex at different rates. This creates an electrical circuit. When the metal in the thermostat reaches the temperature you've set on your control panel, it shuts off heating element's power. As the oven cools it expands the bimetallic strip in a circuit, re-establishing it and turning on heating element. This process continues to ensure a constant temperature in your oven. The oven must be disconnected and all screws removed to identify the problem with the thermostat. 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 close to it the thermostat is operating properly and doesn't need to be replaced. If the multimeter does not read anything it means that the thermostat is defective. It is time to get it replaced. Cooker Spare Parts recommends that you replace the thermostat with a fresh one of the same type as the one you have. The thermostats are sold at a reasonable cost online or at a kitchen goods shop. Bake Element The bake element is essential to the functioning of your oven. It generates heat that lets it cook food items. It's a simple element that transforms electricity into high temperatures for baking, roasting, and broiling. Heating elements are typically found in electric ranges and ovens and can be either uncovered or hidden under the floor of the oven. In general oven heating elements comprise of high-resistance materials such as nickel-chromium. They convert electrical energy into heat through the process of resistance, which then radiates throughout the oven's interior to raise the temperature to the desired degree for cooking different types of foods. When you switch on your oven, the heating element begins to work by generating heat through the high-voltage electricity flowing across its metal surface. When the electric current is flowing through it, the element heats up. The element will turn red hot when it is at the desired temperature. The baked element is the primary source of heat used in most oven functions. It's usually located at the bottom of the oven. A lot of ovens that are automated also use it for self-cleaning. When it starts to burn out you may be noticing that your oven doesn't preheat as quickly or that your food is not cooked through completely. To verify that you have a working oven baking element connect your multimeter to its black and red ports, then rub the probes made of steel against each other on the opposite side of your element. The other end should be placed against one of its terminals, and put your hand on it to determine if the element is warm to the touch. If not, take it off and try again. Broil Element The broil element, typically located at the top of the cavity, provides high heat to cook or char the food. Broil settings in ovens are ideal for quick grill meat or crisp vegetables, to heat up lasagna, or caramelize the topping of the 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 made up of metal wires, wrapped in an insulating expanded product known as perlite. The core of the element is covered with a stainless steel outer layer to protect the wires against direct contact with the oven. The three-layer structure reduces the broil element's temperature, making it more secure and efficient than older types of elements. While you can use any heating element in your oven, make sure to select one that is compatible with the wattage rating of your oven. Using a different wattage can cause damage to your oven or cause it to overheat. You can determine the wattage of your oven and the rating of the new heating element by examining their current and voltage ratings on the oven's control panel. Verify the resistance of the previous element, and compare it with the wattage rating of the new element. ovens and hobs of an oven element the more power it uses. Replace the broiler element as soon as possible if it is not working or is acting up. It is crucial for your oven to function correctly to be able to cook all of your favorite food items. If your oven doesn't function in any way, or just intermittently then the problem may be in a different part. Light Bulb and Assembly The oven light helps keep an eye on the food as it cooks, without having to open the door and let heat escape. The light also informs you when the casserole is ready. It's not unusual for the bulb to go. This can be frustrating but it's an simple fix that you can do yourself. Check that the breaker is not tripped, and that the connector has three prongs. First, remove the old light bulb and then locate the new one. You may have to look online for the right replacement bulb that matches the wattage of your oven. Some appliances use standard 40-watt bulbs and others require a halogen bulb up to 50 watts. Be aware that the oil from your hands could damage a halogen bulb, so it is recommended to use cotton gloves when handling it. Before you place the new bulb in place You must first take it out of its glass casing. It is important to do this slowly so that you don't fracture it. Then, you'll need to remove the air from the bulb and replace it with a mixture. This will extend the lifespan of the filament. If your bulb keeps going out, there could be a wider electrical problem that needs to be dealt with by an expert. Verify that you're using the correct oven bulb and look over your Use and Care Guide for additional troubleshooting tips. Remember to unplug the oven and shut off the power before you start any repairs. This will protect you from electrical shock. Vent Tube The vent tube is an essential oven component that allows for an airflow within the cavity. This allows the bake element to circulate heat around the oven and ensures the temperature is evenly dispersed. It also allows vapors to be released from the oven, and smoke to be drawn from the cooking surface. It is crucial for the proper functioning of any electric or gas oven. Oven vent tubes can become blocked or blocked due to several reasons. Accidental spills and splatters from cooking can leave sticky residues on oven vents, which attract dust and other debris that can eventually cause blockages or clogs in the course of time. Grease and oil particles may be blown into the air and settle around the vents, and vice versa. Other environmental factors such as kitchen and construction projects can cause dust to enter the vents. This can cause clogs. Depending on the oven model, the vent tube may include a bottle guide 20 and spreader 46, as well as fill tip 12 that are formed by 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 effortlessly placed into various sizes and forms of bottle necks. A blocked vent tube may cause a decrease in pressure within the enclosure, which can lead to an exhaust downdraft, which pulls the exhaust backwards and down the vent, causing damage to the oven components. If you suspect that your vent tube is blocked or blocked, consult an expert for assistance. They will identify the problem and offer suggestions on how to remove or clean the vent.
