How to Repair Common Oven Parts
Ovens are a kitchen appliance that is commonly used to cook food. The heat from the oven sterilizes food items and kills the majority of microorganisms.
All bakers need an accurate oven thermometer. Understanding how your oven works will help improve your baking and roasting skills and eliminate those frustrating hot spots that cause havoc with cakes, cookies and other baked items.
Thermostat
The thermostat is among the most important parts of your oven, assisting to make sure that the temperature of your food is exactly what you've set on your control panel. However, just like any other electronic mechanical switch or sensor, it can sometimes have problems that result in the oven going over or under heat, or not be able to keep the temperature you've set.
The oven thermostat is an extremely small strip of two different metals that are bonded together. When exposed to heat the different metals expand and flex at different rates, creating or breaking an electrical circuit. When the metal in your thermostat reaches the temperature that you set on your control panel, it will shut off power to the heater. As the oven cools down the bimetallic strip contract, re-establishing the circuit and activating the heating element. This cycle is constantly repeated to ensure that the temperature remains constant within your oven.
To identify a problem with the thermostat, you'll need to unplug the oven and ensure that all screws holding it in place have been removed. Set your multimeter to the Ohms setting and then test the thermostat. If the multimeter shows zero or close to zero it means that the thermostat is working correctly and doesn't require to be changed.
If the multimeter fails to detect anything it means that the thermostat is defective. It needs to be replaced. Cooker Spare Parts recommends that you replace the thermostat with a fresh one of the same type that your old one. They can be purchased on the internet or in an appliance store and are available at a reasonable price.
Bake Element
The bake element is essential to the functioning of your oven. It generates heat that lets it cook food. It's an easy component that transforms electricity into high temperatures for baking, roasting and broiling. Heating elements are commonly found in electric ranges and ovens, and they can be covered or hidden beneath the oven's floor.
The majority of oven heating elements are made from high-resistance materials like nickel-chromium alloy. They work by converting electricity into heat via resistance. This heat then radiates through the oven's interior to reach the temperature required to cook different kinds of food.
When you switch on your oven, the heating element begins to generate heat through the high-voltage electricity flowing across its metal surface. When electricity is flowing through it the element is heated. When the element reaches the temperature it is intended to it begins to be lit up in red hot.
The baked element is the main source of heat for most oven functions. It's usually found in the bottom of the oven and is used to perform the self-cleaning function in many ovens with automatic cleaning. You may be noticing that the oven does not heat up as quickly, or that your food hasn't been cooked to perfection.
To determine if you have a functioning oven baking element connect your multimeter to its red and black ports, then touch the probes made of metal against each other on one side of the element. Place the other end against one of its terminals and place your hand on it to test whether the element is warm to the touch. If not, remove it and try again.
Broil Element
The broil element, usually found at the top of your cavity offers high temperatures to brown or char foods. Broil settings in ovens are a great way to quickly cook meat crisp vegetables, heat lasagna or caramelize the top of the casserole.
Similar to the bake element the broiler heating element converts electrical energy into heat via the process of resistance. It is made up of an internal core of wires made of metal wrapped in insulating perlite material. The inner core is then wrapped in an outer layer of stainless steel to shield the wires from direct contact with the oven. The three-layer structure helps reduce the temperature of the broil element making it more durable and safer than older types of elements.
While you are able to use any heating element in your oven, you should choose one that matches the rated wattage of your oven. Utilizing a different wattage may harm your oven or cause it to overheat. The voltage and current ratings of the latest heating elements can be located on the control panel of your oven. This will allow you to examine the wattage and rating of your oven.
hob uk Ovens And Hobs is also advisable to check the resistance of your previous element and compare it to the power of the new broiler heating element. The higher the resistance of an oven element, the more power it draws.
If your broiler heating element is not working or functions in any way, you should replace it immediately. Your oven must work properly for you to to cook your favorite foods. However, if your oven isn't working at all or only intermittently, the issue could be in a different area of your oven.
Light Bulb and Assembly
The oven light lets you keep an eye on your food as it cooks, without opening the door to let heat escape. The light will also let you know when the casserole is done. However, it's not uncommon for the light bulb to go out. This can be frustrating but it's an easy repair that you can accomplish yourself. Before you begin, be sure that the breaker hasn't been tripped and that the three-prong connector remains intact.
Take out the old bulb and then look for the new bulb. You may need to look online for the right replacement bulb that matches the wattage of your oven. Some appliances use standard 40-watt bulbs some require halogen bulbs up to 50 watts. It is recommended to use cotton gloves to shield bulbs from the damage caused by oil.
Remove the glass casing of the bulb before you replace it. Do this slowly to avoid breaking it. Then, you'll need to remove the air from the bulb and fill it with an amalgamation of gases. This will ensure a longer lifespan for the filament.
If your light bulb is constantly blinking it could be an electrical problem that requires a professional to fix. Make sure you're using the correct oven bulb and consult your Use and Care Guide for 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 help protect you from electric shock.
Vent Tube
The vent tube is a crucial oven part as it allows for a tiny amount of airflow to flow within 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 that are released from the oven to escape and also allows smoke to be removed from the cooking surface. It is necessary for the proper operation of any electric or gas oven.
Vents in ovens can get clogged by various reasons. Accidental spills or splatters can leave sticky residues in oven vents. They may draw in dust, debris and other contaminants that could cause obstructions in the course of time. Oil and grease can also be airborne and build up around vents. Other environmental factors, like kitchen and construction projects can create dust in the vents. This can cause clogs.
Based on the oven model the vent tube may comprise an a bottle guide 20 or spreader 46 as well as a fill tip 12 that are integrally formed by the pipe 32. For example, the bottle guide 20 could have a tapered exterior surface that compliments the complementarily tapered inside of the spreader 46 to allow the vent tube to be smoothly inserted into different sizes and forms of bottle necks.
A clogged vent tube can cause a reduction in pressure within the enclosure, which can cause a downdraft that pulls exhaust backwards and down the vent, causing damage to oven's components. If you believe that your vent tube is clogged or blocked, call an expert for assistance. They will diagnose the problem and offer suggestions for removing or cleaning the vent.
