How to Repair Common Oven Parts
The oven is an appliance in the kitchen that is commonly used to cook food. The heat produced by the oven sterilizes food items and kills the majority of micro-organisms present in them.
A precise oven thermometer is essential for all bakers. Knowing how your oven functions can help you improve your baking and roasting skills and eliminate those frustrating hot spots that cause havoc with cookies, cakes and other baked goods.
Thermostat
The thermostat is an important part of your oven. It is used to ensure that the temperature of food matches the temperature that you set on the control panel. It can be problematic as is any other switch or sensor that is electro-mechanical. The oven could overheat or underheat, or not keep the temperature you set.
The oven thermostat is basically tiny strips of two different metals that are joined. When heated by the oven, the metals expand or flex at different rates. This creates an electrical circuit. When the metal in the thermostat attains the temperature you've set on your control panel it shuts off heating element's power. As the oven cools the bimetallic strip expands to re-establish the circuit before turning on the heating element. This process is repeated over and over to maintain a constant temperature within your oven.
You'll need the oven disconnected and all screws removed to identify a thermostat problem. If you have a multimeter (which is a tool that measures the electrical current), set it to the ohms level and then test the thermostat. If the multimeter reads zero or very close to it, then the thermostat is functioning properly and doesn't need to be replaced.
If the multimeter doesn't read anything, then the thermostat is not working properly and must be replaced. Cooker Spare Parts suggests that you replace your thermostat with a thermostat of the same type as the old one. The thermostats are available for purchase at a reasonable price online or in a kitchen products shop.
Bake Element
The bake element is essential to the operation of your oven. It produces the heat needed to cook food items. It's an easy component that converts electricity into high temperatures for baking, roasting, and broiling. Electric ovens and ranges usually have heating elements, which are either visible or hidden beneath the floor.
Generally, oven heating elements are constructed of high-resistance materials such as nickel-chromium alloy. best oven Ovens & Hobs convert electricity into heat through resistance. This heat then radiates through the oven's interior to achieve the desired temperature to cook various types of food.
When you switch on your oven, the heating element begins to work by generating heat by the high-voltage electricity flowing across its metal surface. The element is a coil or ribbon (straight or corrugated) of wire, and when the electric current passes through it, it starts to heat up. The element will appear red hot when it reaches the desired temperature.
The baked element is the primary source of heat for the majority of oven functions. It's typically located at the bottom of the oven and is also used to clean the oven in many ovens with automatic cleaning. You may observe that the oven does not warm up as quickly, or that your food isn't fully cooked.
To check for a working oven baking element plug your multimeter into its red and black ports, then rub the metal probes against each other on the opposite side of your device. Place the other end of the baking element against one terminal and then place your hand on it. If the element feels warm, take it off it and start testing again. If it's not, remove the element and try again.
Broil Element
The broil element is usually located in the top of the oven cavity and provides the same high temperature as a grill to cook or brown food. Broil settings in ovens are ideal for quick sear meat or crisp vegetables, to heat up lasagna or caramelize the topping of a casserole.
Similar to the bake element the broiler heating element converts electrical energy into heat via the process of resistance. It is comprised of an inner core comprised of metal wires, which are wrapped in an insulating and expanded product known as perlite. The inner core is then wrapped in an outer layer of stainless steel, which protects the wires from direct contact with the oven. The three-layer structure helps lower the broil element's temperature which makes it more secure and efficient than older styles of elements.
You can use any heating element for baking or broiling in your oven. But, you must select one that matches the wattage that your oven is rated for. Utilizing a different wattage may cause damage to your oven or cause it to overheat. You can verify the power of your oven and the rating of the new heating element by checking their voltage and current ratings on the control panel of your oven.
It is also advisable to check the resistance of your previous element and compare it to the power output of your new broiler heating element. The higher the resistance of an oven element the more power it draws.
If your broiler heating element is acting up or doesn't work at all, you must replace it right away. It's important that your oven function properly to cook your most loved foods. If, however, your oven is not working at all or only intermittently, the issue may be with a different part of your oven.
Light Bulb and Assembly
The oven light lets you keep an eye on your food as it cooks, without having to open the door and let heat escape. The light will also notify you when the casserole has been cooked. It's not unusual for the bulb to die. It can be a hassle, but it's a relatively simple fix that you can accomplish yourself. Before you start, make sure that the breaker hasn't been tripped and that the three-prong connector remains intact.
Remove the old bulb and then look for the new bulb. It is possible to search the internet for a replacement that matches the wattage and the type of oven you have. Some ovens have standard appliance bulbs of 40 watts and others require lamps that are halogen up to 50 watts. Be aware that the oil from your hands could damage a halogen bulb, so consider using cotton gloves when handling it.
Before putting the new bulb in place it is important to first remove it from its glass casing. You should do this slowly to avoid breaking it. Then, you'll need to evacuate the air inside the bulb and fill it up with gas mixture. This will ensure a longer lifespan for the filament.
If your bulb is always going out it could be due to an electrical problem that requires the assistance of a professional. Make sure you're using the correct oven bulb and check your Use and Care Guide to get additional troubleshooting tips. Also, remember that it's a good idea to unplug your oven and disconnect it from the outlet before you begin any repair. This will protect you from electrical shock.
Vent Tube
The vent tube is a crucial oven component because it allows for a small amount of airflow to flow within the cavity. This allows the bake element to circulate heat around the oven and ensures that the temperature is evenly dispersed.
It also allows vapors from the oven to escape, as well as allows smoke to be drawn away from the cooking surface. It is essential to ensure the proper operation of any electric or gas oven.
Vents in ovens can get blocked or clogged due to a variety of reasons. Accidental spills or splatters can leave sticky remnants in oven vents. These can attract debris, dust and other contaminates that could cause blockages in the course of time. Oil and grease can also become airborne and settle around vents. Other environmental factors, like kitchen renovations and construction work, could introduce dust or other pollutants into the vents, resulting in obstructions or clogs.
Based on the type of the oven, the vent tube can comprise a spreader 46 and the fill tip 12, and a bottle guide 20 that are integrally formed into the pipe 32. The bottle guide 20 may have a tapered edge that matches the tapered inner edge of the spreader, allowing the vent tubes to be inserted easily into different sizes and shapes bottle necks.
A clogged vent tube can cause a loss in pressure within the enclosure, which can lead to an exhaust downdraft, which pulls the exhaust backwards and then down the vent, causing damage to oven's components. If you suspect that the vent tube in your oven is clogged or blocked, contact an expert for assistance. They will determine the cause and make recommendations on how to clean or clean the vent.
