How to Repair Common Oven Parts
Oven is a kitchen appliance that is commonly used to cook food. The heat from the oven sterilizes food and kills most of the micro-organisms in them.
All bakers need an accurate oven thermometer. Knowing how your oven functions will improve your baking cooking, roasting and cooking skills. It will also help eliminate those hot spots that can cause damage to cakes, cookies and baked products.
Thermostat
The thermostat is one of the most important parts of your oven, helping make sure that the temperature of your food is in line with the temperature you've set on your control panel. It can be problematic as is any other sensor or switch that is electro-mechanical. The oven can overheat or underheat, or not maintain the temperature you set.
The oven thermostat is essentially an extremely small piece of different metals that are bonded. When heated to a certain temperature, the two metals expand or flex at different rates. This creates an electrical circuit. When the thermostat's metal is at the temperature you've set on the control panel, it turns off the heating element's power. As the oven cools the bimetallic strips expand, re-establishing circuit and turning on heating element. This process continues to ensure that the temperature remains constant within your oven.
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, hob and oven then test the thermostat. If the multimeter reads 0 or very close to it, then the thermostat is working correctly and doesn't need to be replaced.
If the multimeter doesn't read anything, then the thermostat is faulty and needs to be replaced. Cooker Spare Parts suggests that you replace your thermostat with a similar type as the previous one. The thermostats are sold at a reasonable cost online or at a kitchen products shop.
Bake Element
Ovens are not complete without the bake element, which creates heat to make your oven cook food. It's a simple element that converts electricity into high temperatures for baking, roasting and broiling. Heating elements are typically found in electric ovens and ranges, and they can be either covered or concealed under the floor of the oven.
In general oven heating elements are made up of high-resistance elements like nickel-chromium. They work by converting electrical energy into heat via the process of resistance which radiates outwards into the oven's interior, causing it to increase the temperature to the desired level for cooking different types of food.
When you switch on the oven the heating elements begin to produce heat through the high-voltage current flowing across the metal's surface. The element is a ribbon or coil (straight or corrugated) of wire, and when the electric current flows through it, it begins to heat up. The element will appear red hot when it is at the desired temperature.
The baked element is the main source of heat in most oven functions. It's usually located in the bottom of the oven, and is used to clean the oven in many automatic oven models. If it starts to get hot, you might find that your oven isn't able to heat up as fast or that your food is not fully cooked.
Connect your multimeter to its red and Oven uk black ports. Then, press the probes made of metal on one end of the element to each other. Place the other end of the element against one terminal and then place your hand on it. If the element feels warm, take it off it and try testing it again. If it's not, take off the element and test again.
Broil Element
The broil element, typically located at the top of your cavity, offers high heat to brown or char foods. The broil setting in your oven is a great option for quickly searing meat, crisping vegetables, reheating lasagna, or caramelizing the top of the casserole.
The broiler heating element is similar to the bake element in that it converts electrical energy through resistance into heat. It is comprised of an inner core comprised of metal wires, wrapped in an insulating, expanded material called perlite. The core of the element is covered with an outer layer of stainless steel to shield the wires from direct contact with the oven. The three-layer design helps lower the temperature of the broil element, making it safer than older styles.
You can use any heating element for baking or broiling in your oven. However, you should choose one that is in line with the wattage that your oven is rated for. A different wattage may cause damage to your oven or cause it overheat. The voltage and current ratings of the latest heating elements can be found on the control panel of your oven. This will allow you to check the wattage and rating of your oven.
It is also advisable to check 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.
Replace the element in your broiler immediately if it is not working or if it is acting up. Your oven must function properly for you to be able to cook your favourite meals. However, if your oven is not working at all, or is only working intermittently, the issue could lie with another part of your oven.
Light Bulb and Assembly
The oven light helps keep an eye on the food as it cooks, without opening the door to let heat escape. The light also lets you know when the casserole is ready. It's not unusual for the light bulb to fail. It can be a hassle, but you can do it yourself. Before you begin, be sure that the breaker hasn't tripped and that the three-prong connector is intact.
First, remove the light bulb that was in use and then locate the new one. You may have to look online to find a replacement that matches the wattage and type of your oven. Some ovens use standard 40-watt appliance bulbs and others require halogen bulbs up to 50 watts. Consider using cotton gloves to shield the bulbs from the damage caused by oil.
Before putting the new bulb in place, you should first remove it from its glass casing. Do slowly to avoid breaking it. You'll then need to remove the air from the bulb and replace it with the mixture. This will ensure a longer lifespan of the filament.
If your bulb is constantly being replaced, it may be a larger electrical issue that should be handled by a professional. Make sure you're using the correct oven uk bulb and look over your Use and Care Guide to find more troubleshooting advice. And remember that it's always a good idea to unplug your oven and disconnect it from the outlet before you begin any repair. This will protect you from electric shock.
Vent Tube
The vent tube is an essential oven part that allows for a tiny airflow inside the cavity. This allows the bake element to circulate heat around the oven, ensuring that the temperature is evenly distributed.
It also allows the vapors escape from the oven and smoke to be drained from the cooking surface. It is essential for efficient operation of any electric or gas oven.
Vents for ovens uk can become blocked or clogged due to a variety of factors. Accidental spills or splatters could leave sticky residues in oven vents. They may attract dust, debris and other contaminates that could cause blockages in the course of time. Grease and oil may also become airborne, and build up around vents. Other environmental factors like kitchen and construction work can introduce dust into the vents. This can cause clogs.
Depending on the oven model the vent tube could comprise an a bottle guide 20, spreader 46 and fill tip 12 that are integrally constructed with the pipe 32. The bottle guide 20 could be fitted with a tapered outer edge that is complemented by the tapered inner edge of the spreader. This allows the vent tubes to slide effortlessly into various sizes and shapes of bottle necks.
A clogged or blocked vent tube can cause the loss of pressure inside the enclosing structure. This can create a downdraft situation which pulls exhaust down vent and backwards towards the oven's burners, Best oven causing damage to oven components. Consult a professional if you think your vent pipe may be clogged or blocked. They will diagnose the problem and give suggestions for clearing or cleaning the vent.
