How to Repair Common Oven Parts The oven is a kitchen appliance that is used to cook food items. The heat generated by the oven sterilizes food items and kills the majority of microorganisms. An accurate oven thermometer is a necessity for bakers of all kinds. Understanding how your oven works will help improve your baking and roasting abilities and eliminate those irritated hot spots that can cause havoc with cookies, cakes and other baked products. Thermostat The thermostat is an essential part of your oven. It helps to ensure that the temperature of food matches 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 can overheat or underheat, or simply not maintain the temperature you have set. The oven thermostat is an extremely small strip of two different metals connected. When heated the various metals expand and contract at different rates, creating or breaking an electrical circuit. When the metal in your thermostat reaches the temperature you have set on the control panel it will shut off power to the heater. As Best ovens UK expands the bimetallic strip to re-establish the circuit before activating the heating element. This cycle is repeated continuously to maintain a constant oven temperature. You'll need the oven disconnected and all screws removed to diagnose a thermostat problem. Set Best ovens to the Ohms setting and then test the thermostat. If the multimeter shows zero or close to zero the thermostat is operating properly and doesn't need to be changed. If the multimeter does not read anything, it's likely that the thermostat is faulty and must be replaced. Cooker Spare Parts recommends that you replace the thermostat with a fresh one of the same kind as your old one. They can be purchased through the internet or at an appliance store and can be purchased at a reasonable cost. Bake Element Ovens aren't complete without the bake element, which provides heat to make your oven cook food. It's a simple element that transforms electricity into high temperatures for baking, roasting, and broiling. Heating elements are usually found in electric ranges and ovens and can be covered or hidden beneath the oven's floor. In general oven heating elements are made up of high-resistance materials such as nickel-chromium. They convert electricity into heat via resistance. This heat then radiates through the oven's interior to reach the temperature required to cook different kinds of food. When you start the oven, the heating elements begin to generate heat by the high-voltage electric current flowing across the metal surface. The element is a coil or ribbon (straight or corrugated) of wire. When the electric current passes through it, it begins to increase in temperature. The element will appear red hot when it reaches the temperature you want. The baked element is the primary source of heat for most oven functions. It is usually located at bottom of the oven. A lot of ovens that are automated also utilize it to clean themselves. If it starts to burn out, you might notice that your oven doesn't preheat as quickly or that your food isn't cooked through completely. To determine if you have a functioning oven baking element connect your multimeter to its red and black ports, and then place the probes made of metal against each other on the opposite 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 try testing it again. If not, remove it and try again. Broil Element The broil element, usually located on the top of the cavity, provides high heat to brown or char the food. The oven's broil setting can be a great way to quickly grill meat, crisp vegetables, reheat lasagna or caramelize the top of the casserole. Similar to the bake element the broiler heating element transforms electrical energy into heat by the process of resistance. It is made up of an inner core consisting of metal wires, which are wrapped in an insulating and expanded product called perlite. The inner core is enclosed in an outer layer of stainless steel to shield the wires from direct contact with the oven. The three-layer structure helps lower the broil element's temperature making it more durable and safer than older types of elements. While you may use any heating element in your oven, make sure to select one that is compatible with the wattage that is recommended for your oven. A different wattage can damage 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 wattage and rating of your oven. It is also advisable to check the resistance of your old element and compare it with the power output of your new broiler heating element. The greater the resistance, the greater energy an oven element consumes. If the heating element in your broiler is acting up or doesn't work in any way, you should replace it immediately. It's important for your oven to function properly to cook all of your favorite food items. However, if your oven is not working at all, or is only working intermittently, the issue may be with a different part of your oven. 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 lets you know when the casserole is ready. However, it's not uncommon for the light to go out. It can be frustrating but you can fix it yourself. Before you begin, make sure that the breaker isn't tripped and that the three-prong connector remains intact. Remove the old bulb, and then locate the new one. You may have to search online for a replacement bulb that matches the wattage and the type of your oven. Some ovens use standard 40-watt appliance bulbs some require a halogen bulb that is up to 50 watts. Consider using cotton gloves to shield the halogen bulbs from damage caused by oil. Before you place the new bulb in You must first remove it from its glass casing. It is important to take this step slowly to ensure that you don't break it. Then, you'll need to remove the air from the bulb and replace it with an appropriate mixture. This will extend the lifespan of the filament. If your bulb keeps running out, it could be an electrical problem that requires an expert to fix it. 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. Remember to unplug the oven and shut off the power before beginning any repairs. This will keep you from getting an electric shock. Vent Tube The vent tube is a vital oven component that allows for a small airflow inside the cavity. This allows the bake element to circulate heat throughout the oven, making sure that the temperature is distributed evenly. It also allows vapors to escape from the oven, and smoke to be drained from the cooking surface. It is necessary to ensure the proper operation of any gas or electric oven. Oven vent tubes may become blocked by many factors. Accidental spills or splatters may leave sticky residues in oven vents. They can attract debris, dust and other contaminates that could cause blockages in the course of time. Grease and oil particles can become airborne and settle on the vents, too. Other environmental factors, such as kitchen renovations and construction work can bring dust or other pollutants into the vents, resulting in obstructions or clogs. Based on the model of the oven the vent tube may comprise a spreader 46 and a fill tip 12, and an a bottle guide 20 that are incorporated into the pipe 32. For instance, the bottle guide 20 may have a tapered exterior surface that compliments the complementarily tapered inside of the spreader 46. This allows the vent tube to be smoothly fitted into various sizes and designs of bottle necks. A clogged or blocked vent tube can result in a loss of pressure within the enclosing structure. This can create a downdraft situation which pulls exhaust down vent and backwards towards the oven burners, causing damage to oven components. If you suspect that your vent tube is clogged or blocked, contact an expert for assistance. They will determine the cause and offer suggestions on how to clean or clean the vent.
