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 present in them.
All bakers need an accurate oven thermometer. Understanding how your oven functions will improve your baking cooking, roasting and cooking abilities. It will also help eliminate those hot spots that can cause damage to cakes, cookies and baked products.
Thermostat
The thermostat is an essential element of your oven. It helps to ensure that the temperature of food corresponds to the temperature that you set on the control panel. As with any electro mechanical switch or sensor, it may have issues that can cause the oven to over or under heat, or simply not be able to maintain the temperature at what you've set.
The oven thermostat is basically tiny strips of two different metals joined. When heated by the oven, the metals expand or bend at different rates. This creates an electrical circuit. When the thermostat's metal reaches the temperature you've set on the control panel, it shuts off the heating element's power. As the oven cools, the bimetallic strips contract, re-establishing circuit and turning on the heating element. This process is repeated repeatedly to ensure a constant oven temperature.
It is necessary to disconnect the oven and all screws removed to identify the issue with the thermostat. 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 need to be replaced.
If the multimeter isn't reading anything at all, 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 cost on the internet or in a kitchen goods shop.
Bake Element
The bake element is crucial to the operation of your oven. It generates heat that lets it cook food. It's a simple element that converts electricity into high temperatures for baking, roasting, and broiling. Heating elements are usually found in electric ovens and ranges and are either covered or concealed under the oven's floor.
In general, oven heating elements are made from high-resistance components like nickel-chromium alloy. They convert electrical energy into heat using resistance. This heat then radiates through the interior of the oven to achieve the temperature required to cook various types of food.
When you start your oven the heating element gets to produce heat through the high-voltage electricity moving across its metal surface. The element is a ribbon or coil (straight or corrugated) of wire, and as the electric current passes through it, it begins to increase in temperature. When the element reaches its temperature it starts to shine red hot.
The baked element is the main source of heat for most oven functions. It is usually located at bottom of the oven. A lot of ovens that are automated also have it for self-cleaning. You may be noticing that the oven doesn't warm up as quickly, or that your food hasn't been cooked to perfection.
To check for a working oven baking element, plug your multimeter into its black and red ports, and then place the metal probes against each other on one side of the element. The other end of the element on one terminal and place your hand on it. If the element feels warm, remove it and try testing it again. If not, take it off the element and test again.
Broil Element
The broil element is usually located at the upper part of the oven cavity and provides high heat like grills to roast or grill food. The oven's broil setting can be an excellent way to quickly cook 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 by the process of resistance. It is composed of an inner core made up of metal wires, wrapped in an insulating expanded product known as perlite. The core of the element is then covered with an outer layer of stainless steel to protect the wires against direct contact with the oven. The three-layer design helps lower the temperature of the broil element, making it safer than the older models.
You can use any heating element for baking or broiling in your oven. But, you must choose one that is compatible with your oven's rated wattage. A different wattage may cause damage to your oven or cause it to overheat. hobs uk 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.
Check the resistance of your old element, and then compare it to the wattage rating of the new one. The greater 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 immediately. It is crucial for your oven to function properly to cook all of your favorite food items. If your oven isn't functioning at all, or is only working 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 the food cooking without opening the door and let heat escape. The light will also inform you when the casserole is done. It's not uncommon for the light bulb to fail. This can be frustrating but it's an easy repair that you can accomplish yourself. Make sure that the breaker is not tripped, and that the connector has three prongs.
First, remove the old light bulb and then locate the new one. You may have to look online for the right replacement bulb that matches your oven's wattage. Some ovens use standard 40-watt appliance bulbs and others require a halogen bulb that is up to 50 watts. Be aware that the oil in your hands could damage a halogen bulb, so you should use cotton gloves when handling it.
Before you place the new bulb in place You must first remove it from its glass casing. It is important to do this slowly to avoid breaking it. You'll then need to remove the air from the bulb and replace it with a mixture. This will ensure a longer lifespan for the filament.
If your bulb is constantly going out, there could be a bigger electrical issue that should be addressed by an expert. Double check that you are using the correct oven bulb and check your Use and Care Guide for more help in troubleshooting. Make sure to unplug the oven and turn off the power prior to beginning any repairs. This will keep you from getting an electric shock.
Vent Tube
The vent tube is an essential oven part as it allows for a tiny amount of airflow to flow within the cavity. This permits the bake element to circulate heat throughout the oven, making sure that the temperature is evenly distributed.
It also allows the vapors to be released from the oven, and smoke to be drained from the cooking surface. It is essential 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 may leave sticky remnants in oven vents. These can attract debris, dust and other contaminants that can cause blockages over time. Oil and grease can also be airborne and then settle on vents. Other environmental factors such as construction and kitchen renovations can cause dust to enter the vents. This can cause clogs.
Based on the model of the oven the vent tube may comprise a spreader 46 and a fill tip 12, and an a bottle guide 20 that are integrated into the pipe 32. For instance, the bottle guide 20 could have a tapered outer layer that compliments the complementarily tapered inner surface of the spreader 46, allowing the vent tube to be easily fitted into various sizes and shapes of bottle necks.
A blocked vent tube may cause a reduction in pressure inside the enclosure, which could cause an exhaust downdraft, which pulls the exhaust backwards and then down the vent, causing damage to the oven's components. If you think that the vent tube in your oven is clogged or blocked, call a professional for help. They will determine the cause and provide recommendations for removing or cleaning the vent.
