How to Repair Common Oven Parts
The oven is a kitchen appliance that is used to cook food items. The heat of the oven sterilizes food items and kills the majority of microorganisms.
An accurate oven thermometer is essential for bakers of all kinds. Knowing how your oven functions can help you improve your baking and roasting skills and eliminate those irritated hot spots that can cause havoc with cookies, cakes and other baked items.
Thermostat
The thermostat is among the most crucial components of your oven, helping make sure that the temperature of your food is in line with what you've set in your control panel. As with any electro mechanical switch or sensor, it may have issues that cause the oven to over heat or under heat, or just not be able to keep the temperature you've set.
The oven thermostat is essentially an extremely small piece of different metals that are bonded. When heated by the oven, the metals expand or bend at different rates. This creates an electrical circuit. When the metal in your thermostat reaches the temperature you have set on the control panel it will shut off heating element's power. As the oven cools it expands the bimetallic strip in a circuit, re-establishing it and turning on heating element. This process is repeated repeatedly to maintain a constant oven temperature.
You'll need the oven disconnected and all screws removed in order to determine the problem with the thermostat. Set your multimeter to the Ohms setting and then test the thermostat. If the multimeter displays zero or close to zero the thermostat is operating correctly and does not need to be changed.
If the multimeter does not read anything it means that the thermostat is defective. It must be replaced. Cooker Spare Parts suggests that you replace your thermostat with a thermostat of the same type as the old one. They are available on the internet or in the kitchen store, and can be bought at a reasonable cost.
Bake Element
Ovens are not complete without the bake element, which provides heat to make your oven cook food. It's an easy component that converts electricity into high temperatures for baking, roasting and broiling. Heating elements are commonly found in electric ranges and ovens and are either covered or concealed under the oven's floor.
In general oven heating elements comprise of high-resistance metals such as nickel-chromium. They convert electricity into heat through resistance. This heat then radiates through the oven's interior to attain the temperature required to cook various types of food.
When you start your oven, the heating element begins to work by generating heat from the high-voltage electrical energy that flows across its metallic surface. When electricity runs through it the element is heated. The element will turn red hot when it reaches the temperature you want.
The baked element is the primary source of heat for most oven functions. It is usually located at bottom of the oven. Many automatic oven models also utilize it to clean themselves. When it starts to burn out you may find that your oven isn't able to preheat as quickly or that your food is not fully cooked.
To verify that you have a working oven baking element plug your multimeter into its black and red ports, and then place the metal probes against each other on the opposite side of your device. The other end should be placed against one of its terminals and then place your hands on it to test if the element is warm to the contact. If not, take it off the element and test again.
Broil Element
The broil element, usually found at the top of your cavity provides high heat to cook or char foods. The broil setting of your oven is an excellent choice for quickly searing meat and vegetables, crisping up vegetables, warming lasagna or making caramel on top of the casserole.
Similar to the bake element the broiler heating element converts electrical energy into heat by the process of resistance. It is made up of an internal core of wires made of metal wrapped in insulating perlite product. The inner core is enclosed in an outer layer of stainless steel to protect the wires from direct contact with the oven. The three-layer design helps lower the temperature of the broil element, making it safer than the older models.
While you may use any heating element in your oven, make sure to select one that is compatible with the wattage rating of your oven. A different wattage could damage your oven or cause it to overheat. The current and voltage ratings of the latest heating elements can be found on the control panel of your oven. This allows you to determine the power and rating of your oven.
You should also check the resistance of your old element and compare it to the power of the new broiler heating element. The greater the resistance, the more energy an oven element consumes.
Replace your broiler element immediately If it's not functioning or if it's acting up. It is crucial for your oven to function properly so that you can cook all your favorite food items. If your oven does not operate in any way, or just intermittently, the issue may be with another part.
Light Bulb and Assembly
The oven light helps keep an eye on your food cooking without having to open the door and let the heat escape. The light will also notify you when the casserole is done. It's not uncommon for the bulb to die. It can be frustrating but you can fix it yourself. Before you start, make sure that the breaker isn'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. It is possible to look online to find the correct replacement bulb that is compatible with the wattage of your oven. ovens uk -watt appliance bulbs, while others require a halogen bulb up to 50 watts. Be aware that the oil in your hands can damage a halogen bulb, so it is recommended to use cotton gloves when handling it.
Remove the glass casing of the bulb prior to replacing it. You should do this slowly to avoid breaking it. You'll then need to remove the air from the bulb and replace it with the mixture. This will provide a longer life for the filament.
If your bulb is always running out it could be due to an electrical issue that requires an expert to fix it. Verify that you're using the correct oven bulb and look over your Use and Care Guide to get more help in troubleshooting. And remember that it's always a good idea to unplug your oven and disconnect it from the outlet before you start any repair. This will help protect you from electric shock.
Vent Tube
The vent tube is a vital oven component that allows for a tiny airflow inside the cavity. This permits the bake element to circulate heat throughout the oven, ensuring that the temperature is distributed evenly.
It also allows vapors from the oven to escape, as well as allows smoke to be removed from the cooking surface. It is vital for the proper functioning of any electric or gas oven.
Oven vent tubes may become blocked due to many factors. Accidental spills or splatters may leave sticky residues on oven vents. They may attract debris, dust and other contaminants that could cause blockages in the course of time. Grease and oil particles may be blown into the air and settle around the vents, too. Other environmental factors, like kitchen renovations and construction work, can bring dust or other contaminants into the vents, leading to clogs or blockages.
Depending on the oven model, the vent tube may comprise the bottle guide 20, spreader 46 and fill tip 12 that are integrally formed by the pipe 32. For instance the bottle guide 20 may have a tapered outer surface which is in harmony with the tapered inner surface of the spreader 46 to allow the vent tube to be smoothly fitted into various sizes and designs of bottle necks.
A clogged vent tube can cause a reduction in pressure inside the enclosure, which can cause a downdraft that pulls exhaust backwards and then down the vent, damaging the oven components. Consult a professional if think your vent pipe may be clogged or blocked. They will identify the issue and offer suggestions for removing or cleaning the vent.
