How to Repair Common Oven Parts The oven is an appliance used in kitchens that is typically used to cook food items. The heat produced by the oven sterilizes food and kills most of the micro-organisms present in them. A precise oven thermometer is an essential for all bakers. Understanding how your oven works will help improve your baking and roasting abilities and eliminate those annoying hot spots that can cause havoc with cookies, cakes and other baked goods. Thermostat The thermostat is an important part of your oven. It helps to ensure that the temperature of food corresponds to the temperature you set on the control panel. Unfortunately, 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 at what you've set. The oven thermostat is essentially a small strip of two different metals that are bonded. When exposed to heat, the different metals expand and bend at different rates, forming or breaking an electrical circuit. When the metal in your thermostat reaches the temperature you set on your control panel it will shut off power to the heater. When the oven cools down the bimetallic strip contract to re-establish the circuit before turning on the heating element. This cycle continues for a long time to maintain a constant oven temperature. It is necessary to disconnect the oven and all screws removed to identify the problem with the thermostat. Set your multimeter to the Ohms setting and then test the thermostat. If the multimeter reads zero or close to zero, the thermostat is functioning correctly and doesn't require to be changed. If the multimeter isn't reading anything, it's likely that the thermostat is faulty and requires replacement. Cooker Spare Parts suggests that you replace your thermostat with a thermostat of the same type as the previous one. They are available through the internet or at an appliance store and are available at a reasonable price. Bake Element The bake element is crucial to the operation of your oven. It provides heat that lets it cook food. It's a basic element that converts electricity into the high temperatures needed for baking, roasting, and broiling. Heating elements are usually found in electric ranges and ovens and are either covered or concealed under the floor of the oven. In general oven heating elements comprise of high-resistance elements such as nickel-chromium. They work by converting electrical energy into heat through the process of resistance which radiates outwards into 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 generate heat by the high-voltage electricity moving across its metal surface. When electricity is flowing through it the element gets heated up. The element will glow red hot when it is at the desired temperature. The baked element is the main source of heat for most oven functions. It's usually located at the bottom of the oven, and is used to clean the oven in many ovens with automatic cleaning. You might observe that your oven doesn't warm up as quickly, or that your food isn't cooked completely. To check for a working oven baking element plug your multimeter into its red and black ports, then touch the metal probes against each other on the opposite side of your element. The other end of the element against 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 try again. Broil Element The broil element, usually found at the top of your cavity provides high temperatures to brown or char the food. The broil setting of your oven is an excellent option for quickly searing meat, crisping vegetables, reheating lasagna or caramelizing the top of the casserole. The broiler heating element is comparable to the bake element in that it converts electrical energy by resistance into heat. It is comprised of an inner core of wires made of metal wrapped in an insulating expanded perlite material. The inner core is wrapped in an outer layer of stainless steel to protect the wires from direct contact with the oven. The three-layer design helps lower the temperature of the broil element, making it safer than the older models. While you can use any baking or broiling heating element in your oven, you should select one that is compatible with the wattage rating of your oven. A different wattage could cause damage to your oven or cause it to overheat. The voltage and current ratings of the new heating elements can be found on the control panel of your oven. This allows you to determine the power and rating of your oven. You should also check the resistance of your previous element and compare it to the wattage of your new broiler heating element. The greater the resistance of an oven element, the more power it uses. Replace the element in your broiler immediately If it's not working or is acting up. It is essential that your oven function properly so that you can cook your most loved foods. If your oven isn't working in any way or only intermittently, the issue may be in a different area of your oven. Light Bulb and Assembly The oven light lets you keep an eye on the food as it cooks, without having to open the door and let the heat escape. The light also informs you when your casserole is ready. It's not uncommon for the bulb to go out. It can be quite frustrating, but you can do it yourself. Make sure the breaker isn't tripped and that the connector has three prongs. Take out the old bulb and then look for the new bulb. hobs and ovens may need to look online to find the correct replacement bulb that is compatible with your oven's wattage. Some ovens utilize standard appliances with bulbs of 40 watts some require a halogen lamp up to 50 watts. It is recommended to use cotton gloves to shield the bulbs from the damage caused by oil. Before you put the new bulb in place, you should first remove it from its glass casing. It is important to do this slowly so that you don't break it. Then, you'll need to remove the air from the bulb and replace it with the mixture. This will provide a longer life for the filament. If your light bulb is constantly going out, it could be an electrical issue that needs an expert to fix it. Be sure to double check that you're using a correct bulb for your oven and check out your Use and Care Guide for additional troubleshooting suggestions. Also, remember that hobs oven 's a good idea to unplug your oven and disconnect the power from the outlet prior to you begin any repair. This will keep you from suffering an electric shock. Vent Tube The vent tube is an essential oven component that permits a tiny airflow inside the cavity. This allows the bake element to circulate heat around the oven and ensures the temperature is evenly dispersed. It also allows the vapors that are released from the oven to escape, and also allows smoke to be removed from the cooking surface. It is necessary to ensure the proper operation of any gas or electric oven. Vents in ovens can get clogged or blocked by several factors. Accidental spills or splatters can leave sticky residues in oven vents. These can draw in dust, debris and other contaminants that can cause clogs in the course of time. Oil and grease can also become airborne and settle around vents. Other environmental factors, such as kitchen renovations and construction work can introduce dust or other pollutants into the vents, leading to obstructions or clogs. Depending on the model of the oven the vent tube could comprise a spreader 46, a fill tip 12, and an a bottle guide 20 that are incorporated into the pipe 32. For instance 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 smoothly inserted into different sizes and designs of bottle necks. A blocked vent tube may cause a reduction in pressure inside the enclosure which could cause an updraft that pulls exhaust forward and down the vent, damaging the oven's components. Consult a professional if believe that your vent may be clogged or blocked. They will identify the problem and offer suggestions on how to clear or clean the vent.
