How to Repair Common Oven Parts
The oven is an appliance in the kitchen that is commonly used to cook food items. The heat from the oven sterilizes food items and kills the majority of micro-organisms in them.
All bakers need an accurate oven thermometer. Understanding how your oven functions will help improve your baking, roasting and cooking skills. It will also eliminate those annoying hot spots which can ruin cakes, cookies and baked goods.
Thermostat
The thermostat is one of the most crucial components of your oven, helping to make sure that the temperature of your food is in line with what you've set in the control panel. As with any electro mechanical switch or sensor it can sometimes have problems that can cause the oven to over heat or under heat, or not be able to maintain the temperature at what you've set.
The oven thermostat is an extremely small piece of different metals bonded together. When heated to a certain temperature, the two 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 power to the heating element. As the oven cools it expands the bimetallic strip to re-establish the circuit before activating the heating element. This cycle continues for a long time to ensure a constant oven temperature.
To diagnose a problem with the thermostat you'll need to disconnect the oven and ensure that all of the screws that hold it in place have been removed. If you have a multimeter (which is a tool that detects the electrical current) set it to the ohms level and then test the thermostat. If ovens and hobs or close to zero, the thermostat is functioning properly and doesn't need to be changed.
If the multimeter isn't reading anything at all, then the thermostat is not working properly and requires replacement. Cooker Spare Parts recommends that you replace the thermostat with a new one of the same kind that your old one. The thermostats are sold at a reasonable price on the internet or in a kitchen goods shop.
Bake Element
Ovens aren't complete without the bake element, which is the element that heats up to help your oven cook food. It's a simple component that converts electricity into high temperatures for baking, roasting and broiling. Heating elements are typically found in electric ovens and ranges and can be either covered or concealed under the floor of the oven.
Generally, oven heating elements are constructed of high-resistance materials such as nickel-chromium alloy. They work by converting electricity into heat through resistance. This heat then radiates through the interior of the oven to achieve the temperature required to cook various types of food.
When you switch on the oven, the heating elements begin to produce heat through the high-voltage electric current flowing across the metal surface. When electric current is flowing through it the element gets heated up. When the element reaches its temperature, it starts to shine red hot.
The baked element is the main source of heat in most oven functions. It's usually located at the bottom of the oven and is used to clean the oven in many automatic oven models. You may be noticing that your oven doesn't get hot as fast, or that your food hasn't fully cooked.
Connect your multimeter to its red and black ports. Then, touch the probes made of metal on one end of the element to each other. Place the other end against one of its terminals, and place your hand on it to feel whether the element is warm to the touch. If not, take it off the element and try again.
Broil Element
The broil element, which is typically located at the top of the cavity, provides high heat to brown or char food items. The broil setting in your oven is a great choice for quickly searing meat, crisping vegetables, reheating lasagna, or making caramel on top of the casserole.
The broiler heating element has a similarity to the bake element in that it converts electrical energy via resistance into heat. It is made up of an internal core of wires that are wrapped in insulating perlite product. The inside of the element is then covered with an outer layer of stainless steel to shield the wires from direct contact with the oven. The three-layer structure helps lower the temperature of the broil element making it safer and more efficient than older styles of elements.
You can use any heating element for baking or broiling in your oven. However, it is important to select one that matches your oven's rated wattage. This Resource site could harm your oven or cause it to overheat. You can determine the power of your oven and the rating of the new heating element by examining their current and voltage ratings on the oven's control panel.
You should also test the resistance of your old element and compare it with the wattage of your new broiler heating element. The higher the resistance of an oven element the more power it uses.
If your broiler heating element is acting up or doesn't work at all, you must replace it as soon as possible. It is essential that your oven functions properly so that you can cook all of your favorite food items. If, however, your oven isn't working in any way or only intermittently, the issue could be with a different part of your oven.
Light Bulb and Assembly
The oven light helps you keep an eye on your food as it cooks, without opening the door to let heat escape. The light also alerts you when the casserole is ready. However, it's not uncommon for the bulb to go out. It can be quite frustrating, but you can do it yourself. Check that the breaker is not tripped, and that the connector has three prongs.
Remove the old bulb, and then locate the new one. You may have to look online for the right replacement bulb that is compatible with the wattage of your oven. Some ovens use standard 40-watt appliance bulbs some require a halogen bulb that is up to 50 watts. It is recommended to use cotton gloves to shield bulbs from the damage caused by oil.
Remove the glass casing from the bulb before you replace it. It's crucial to do this slowly so that you don't break it. After that, you'll need to eliminate the air inside the bulb and fill it up with an amalgamation of gases. This will provide a longer life for the filament.
If your bulb is constantly going out, there could be a bigger electrical issue that should be handled by a professional. Verify that you're using the correct oven bulb and check your Use and Care Guide to get more troubleshooting advice. Be sure to unplug your oven and turn off the power before beginning any repairs. This will keep you from getting an electric shock.
Vent Tube
The vent tube is a crucial oven part as it allows for a small amount of airflow to flow inside the cavity. This allows the bake element to circulate heat around the oven and ensures the temperature is evenly distributed.
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.
Vents in ovens can get blocked or clogged due to a variety of reasons. Accidental spills or splatters while cooking can leave sticky residues on the oven vents, which draw dust and other debris which can lead to blockages or clogs over time. Grease and oil particles may be blown into the air and settle around the vents, as well. Other environmental factors, like kitchen renovations and construction work can introduce dust or other pollutants into the vents, leading to blockages or clogs.
Based on the oven model the vent tube may comprise a bottle guide 20 or spreader 46 as well as a fill tip 12 that are integrally constructed with the pipe 32. The bottle guide 20 can be fitted with a tapered outer edge that is complemented by the tapered inner edge of the spreader, allowing the vent tubes to be inserted smoothly into different sizes and shapes of bottle necks.
A clogged or blocked vent tube can cause a loss of pressure within the enclosing structure. This can create a downdraft situation that pulls exhaust down the vent and then backwards over the oven burners, causing damage to the oven's components. If you suspect that the vent tube in your oven is clogged or blocked, call an expert for assistance. They will determine the cause and provide recommendations for removing or cleaning the vent.
