How to Repair Common Oven Parts
Oven is a kitchen appliance that is commonly used to cook food. The heat generated by the oven sterilizes food items and kills most of the micro-organisms that are present in them.
Every baker needs an accurate oven thermometer. Knowing how your oven works will improve your baking cooking, roasting and cooking skills. It will also help eliminate the annoying hot spots that can ruin cookies, cakes and baked items.
Thermostat
The thermostat is one of the most important parts of your oven, helping make sure that the temperature of your food matches what you've set in your control panel. As with any electro mechanical switch or sensor it can have issues that result in the oven going over heat or under heat, or just not be able to maintain the temperature at the level you've set.
The oven thermostat is basically an extremely small strip of two different metals that are joined. When exposed to heat the different metals expand and flex at different rates, creating or breaking an electrical circuit. When the metal in the thermostat reaches the temperature you've set on your control panel it shuts off the power to the heating element. When the oven cools down the bimetallic strip expands to re-establish the circuit before turning on the heating element. This process continues to ensure that the temperature remains constant in your oven.
To identify a problem with the thermostat you'll need to unplug the oven and verify that all of the screws that hold it in place have been removed. Set your multimeter to the Ohms setting, and then test the thermostat. If the multimeter reads 0 or very close to it, then the thermostat is working correctly and doesn't require to be replaced.
If the multimeter doesn't show anything it means that the thermostat is defective. It is time to get it replaced. Cooker Spare Parts suggests that you replace your thermostat with a thermostat of the same model as the one you have. These thermostats are available at a reasonable cost on the internet or in the kitchen store.
Bake Element
Ovens can't be complete without the bake element which creates heat to make your oven cook food. It's a simple component that transforms electricity into high temperatures for baking, roasting, and broiling. Heating elements are typically found in electric ranges and ovens and can be covered or hidden beneath the oven's floor.
In general, oven heating elements are made from high-resistance components like nickel-chromium alloy. They work by converting electrical energy into heat by the process of resistance, which radiates outwards into the oven's interior, causing it to increase the temperature to the desired degree for cooking different types of foods.
When you start your oven the heating element gets to generate heat by the high-voltage electricity that flows across its metallic surface. When the electric current is flowing through it the element gets heated up. The element will glow red hot when it reaches the desired temperature.
The baked element is the primary source of heat in most oven functions. It's usually located at the in the bottom of the oven. Many automatic oven models also use it to clean themselves. When it starts to get hot you may be noticing that your oven doesn't preheat as quickly or that your food is not cooked through completely.
To determine if you have a functioning oven baking element, plug your multimeter into its black and red ports, then touch the probes made of metal against each other on one side of your element. Place the other end of the element on one terminal and place your hand on it. If the element feels warm, remove it and test it again. If it's not, remove the element and try again.
Broil Element
The broil element, typically located at the top of your cavity, provides high temperatures to brown or char food items. The broil setting in your oven is an excellent option for quickly grilling meat or vegetables, crisping them up, reheating lasagna or caramelizing the top of a 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 internal core of wires that are wrapped in insulating expanded perlite material. The inner core is then wrapped in an outer layer of stainless steel to shield the wires from direct contact with the oven. The three-layer design helps to lower the temperature of the broil element, making it safer than the older models.
While Ovens And Hobs may use any heating element in your oven, you should select one that is compatible with the wattage that is recommended for your oven. A different wattage could cause damage to your oven or cause it to overheat. You can determine the power of your oven and the rating of the new heating element by looking at their voltage and current ratings on the oven's control panel.
Examine the resistance of the old element, and then compare it to the wattage ratings of the new one. The greater the resistance of an oven element, the greater power it draws from it.
Replace the broiler element as soon as possible If it's not functioning or if it's acting up. It is crucial for your oven to function properly to cook your most loved foods. However, if your oven is not working in any way or only intermittently, the issue may be with a different part of your oven.
Light Bulb and Assembly
The light allows you to keep an eye on your food while it cooks without opening the door and let the heat escape. The light will also let you know when the casserole has been cooked. It's not uncommon for the light bulb to fail. It can be a hassle, but you can do it yourself. Make sure the breaker is not tripped and that the connector has three prongs.
First, remove the light bulb that was in use and then locate the new one. You may need to search online to find a replacement that matches the wattage and type of oven you have. Some ovens have normal appliance bulbs that are 40 watts in power some require an halogen lamp that can reach 50 watts. It is recommended to use cotton gloves to shield the bulbs from the damage caused by oil.
Remove the glass casing from the bulb prior to replacing it. It's crucial to take this step slowly to ensure that you don't break it. You'll have 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 is always going out, it could be an electrical issue that needs the assistance of a professional. Verify that you're using the correct oven bulb and look over your Use and Care Guide to get additional troubleshooting tips. Remember that it's an excellent idea to unplug your oven and disconnect the power from the outlet prior to you begin any repair. This will prevent you from getting an electric shock.
Vent Tube
The vent tube is an important oven element because it allows for a tiny amount of airflow to be created 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 the vapors to escape 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.
Vents for ovens can become blocked due to various reasons. Accidental spills or splatters while cooking can leave sticky residues on oven vents, which draw dust and other debris which can lead to clogs or blockages over time. Oil and grease particles can become airborne and settle around the vents, too. Other environmental factors, like kitchen and construction projects can create dust in the vents. This can lead to clogs.
Based on the oven model the vent tube could include the bottle guide 20 or spreader 46 as well as a fill tip 12 that are constructed with the pipe 32. The bottle guide 20 can have a tapered outer edge that complements the tapered inside edge of the spreader to allow the vent tubes to slide effortlessly into various sizes and shapes bottle necks.
A clogged or blocked vent tube can cause a loss of pressure within the enclosing structure, which can create a downdraft situation which pulls exhaust down vent and then backwards over the oven's burners, which can cause damage to the oven components. If you suspect that the vent tube in your oven is clogged or blocked, call a professional for help. They will diagnose the problem and provide recommendations for removing or cleaning the vent.
