How to Repair Common Oven Parts
The oven is a kitchen appliance that is typically used to cook food items. The heat produced by the oven sterilizes food and kills the majority of micro-organisms in them.
All bakers need an accurate oven thermometer. Knowing how your oven functions will help improve your baking cooking, roasting and cooking abilities. It will also eliminate those hot spots that can ruin cakes, cookies and baked products.
Thermostat
The thermostat is an essential element of your oven. It helps to ensure that the temperature of food is in line with the temperature you have set on the control panel. Unfortunately, like any other electronic mechanical switch or sensor, it can have issues that cause the oven to over heat or under heat, or just not be able to keep the temperature at the level you've set.
The oven thermostat is basically tiny strips of two different metals joined. When exposed to heat, the various metals expand and contract at different rates, creating or breaking an electrical circuit. When the thermostat's metal is at the temperature you've set on the control panel, it shuts off the power to the heating element. As the oven cools, the bimetallic strip contracts in a way, reestablishing the circuit and activating the heating element. This cycle is repeated continuously to ensure that the oven remains at a constant temperature.
You'll need the oven disconnected and all screws removed to diagnose a thermostat problem. Set your multimeter to the Ohms setting, and then test the thermostat. If the multimeter displays zero or close to zero it means that the thermostat is working correctly and does not need to be changed.
If the multimeter does not read anything at all, then the thermostat is defective and needs to be replaced. Cooker Spare Parts suggests that you replace your thermostat with a similar type as the previous one. Best ovens UK are available on the internet or in a kitchen goods store, and can be bought at a reasonable cost.
Bake Element
The bake element is essential to the functioning of your oven. It produces heat that lets it cook food. It's an easy component that converts electricity into high temperatures for baking, roasting and broiling. Electric ovens and ranges typically have heating elements, which can be either exposed or hidden beneath the floor.
Generally, oven heating elements are made of high-resistance materials such as nickel-chromium alloy. They work by converting electrical energy into heat via the process of resistance which then radiates through the oven interior to raise the temperature to the desired temperature to cook various types of food.
When you switch on your oven, the heating element begins to work by generating heat from the high-voltage electrical energy moving across its metal surface. The element is a ribbon or coil (straight or corrugated) of wire. When the electric current passes through it, it begins to heat up. When the element reaches the temperature it is intended to it starts to be lit up in 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 ovens with automatic cleaning. You might notice that the oven doesn't get hot as fast, or that your food hasn't been cooked to perfection.
Connect your multimeter to its red and black ports. Then, press the probes made of metal on one side of the element to each other. Place the other end against one of its terminals, and then place your hands on it to determine whether the baking element is warm to the contact. If not, take it off the element and start testing again.
Broil Element
The broil element, which is typically located at the top of your cavity, allows high-temperature heat to brown or char food items. Broil settings in ovens are a great way to quickly cook meat, crisp vegetables, reheat lasagna, or caramelize the topping of a casserole.
The broiler heating element has a similarity to the bake element in that it converts electrical energy via resistance into heat. It is comprised of an inner core of wires made of metal wrapped in insulating expanded perlite product. The inner core of the element is then covered with a stainless steel outer layer to shield the wires from direct contact with the oven. The three-layer design can help lower the temperature of the broil element, making it more secure than older designs.
You can use any heating element for baking or broiling in your oven. But, you must choose one that is in line with the wattage of your oven's rating. Using a different wattage can 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 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 to the power output of your new broiler heating element. The higher the resistance of an oven element, the more power it draws.
If the heating element in your broiler is malfunctioning or isn't working at all, you should replace it as soon as possible. Your oven must function correctly to be able to cook your favorite meals. If your oven is not working at all or only intermittently, the problem could lie with another part of your oven.
Light Bulb and Assembly
The light lets you keep an eye on your food while it cooks without opening the door and let heat escape. The light will also let you know when the casserole is finished. It's not unusual for the bulb to die. It can be quite frustrating, but you can fix it yourself. Before you begin, make sure that the breaker isn't tripped and that the three-prong connector is intact.
Remove the old bulb, and then look for the new bulb. You may need to search online to find the correct replacement bulb that is compatible with the wattage of your oven. Some ovens use standard 40-watt appliance bulbs and others require a halogen bulb that is up to 50 watts. You should consider using cotton gloves to shield halogen bulbs from damage caused by oil.
Remove the glass casing of the bulb before replacing it. It's important to take this step slowly to ensure that you don't break it. After that, you'll need to remove the air from the bulb and fill it with an amalgamation of gases. This will prolong the lifespan of the filament.
If your bulb keeps being replaced, it could be a wider electrical problem that needs to be handled by an expert. Verify that you're using the correct oven bulb and look over your Use and Care Guide to find more troubleshooting advice. Remember to unplug the oven and shut off the power before beginning any repairs. This will help prevent suffering an electric shock.
Vent Tube
The vent tube is a vital oven part that allows for an airflow within the cavity. This allows the bake-element to circulate heat throughout the oven, ensuring that the temperature is distributed evenly.
It also allows vapors to escape from the oven, and smoke to be drawn from the cooking surface. It is vital for the efficient operation of any electric or gas oven.
Vents in ovens can get blocked by many factors. Accidental spills and splatters from cooking can leave sticky residues on the oven vents, which draw dust and other debris that can eventually cause clogs or blockages over time. Grease and oil can also become airborne, and settle on vents. Other environmental factors, such as kitchen renovations and construction work could introduce dust or other contaminants into the vents, which can cause blockages or clogs.
Based on the model of the oven the vent tube could comprise a spreader 46 and a fill tip 12, and an a bottle guide 20 that are integrated into 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. This allows the vent tubes to be placed smoothly into different sizes and shapes bottle necks.
A clogged vent tube can cause a loss in pressure inside the enclosure, which can lead to an exhaust downdraft, which pulls the exhaust forward and down the vent, causing damage to the oven's components. Consult a professional if you think your vent pipe may be clogged or blocked. They will identify the issue and provide recommendations for removing or cleaning the vent.
