How to Repair Common Oven Parts
Oven is a common kitchen appliance used to cook food. The heat generated by the oven sterilizes food items and kills the majority of microorganisms.
Every baker needs an accurate oven thermometer. Understanding how your oven works will improve your baking and roasting skills and eliminate those frustrating hot spots that can cause havoc with cakes, cookies and other baked products.
Thermostat
The thermostat is one of the most important parts of your oven, helping to ensure that the temperature of your food is exactly what you've set in the control panel. Unfortunately, like any other electro mechanical switch or sensor, it can sometimes have problems that can cause the oven to over heat or under heat, or simply not be able to maintain the temperature you've set.
The oven thermostat is a small strip of two different metals bonded together. When heated, the metals expand or flex at different rates. This creates an electrical circuit. When the metal in the thermostat is at the temperature you've set on the control panel, it shuts 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 over and over to ensure that the temperature remains constant in your oven.
To identify a issue with the thermostat, you'll have to remove the oven and make sure that all of the screws that hold it in place have been removed. If you have a multimeter (which is a tool that detects electrical current) set it to the ohms setting, and then test the thermostat. If oven with hob shows zero or close to zero, the thermostat is functioning properly and doesn't need to be changed.
If the multimeter doesn't read anything, it's likely that the thermostat is defective and requires replacement. Cooker Spare Parts suggests that you replace your thermostat with one of the same type as the previous one. The thermostats are sold at a reasonable price online or at a kitchen products shop.
Bake Element
The bake element is crucial to the operation of your oven. It generates the heat needed to cook food items. It's a basic element that converts electricity into the high temperatures required to bake, roast, and broiling. Heating elements are commonly found in electric ranges and ovens and are either uncovered or hidden under the oven's floor.
In general, oven heating elements are constructed from high-resistance components like nickel-chromium alloy. They work by converting electrical energy into heat through the process of resistance, which then radiates throughout the oven interior to raise the temperature to the desired level to cook different kinds of foods.
When you start the oven the heating elements start to produce heat due to the high-voltage electric current flowing across the metal surface. The element is a coil or ribbon (straight or corrugated) of wire, and when the electric current flows through it, it starts to increase in temperature. The element will appear red hot when it reaches the temperature you want.
The baked element is the primary source of heat in most oven functions. It's typically located at the bottom of the oven and is also used to clean the oven in many automatic oven models. You may notice that your oven doesn't heat 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 red and black ports, and then place the metal probes against each other on one side of the element. Set the other end of the probe against one of its terminals, and place your hand on it to determine if the element is warm to the touch. If not, remove it and try again.
Broil Element
The broil element, usually located on the top of your cavity offers high heat to brown or char foods. Broil settings in ovens are a great way to quickly cook meat, crisp vegetables, reheat lasagna or caramelize the topping 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 of metal wires wrapped in insulating expanded perlite material. 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 structure reduces the temperature of the broil element, making it more secure and efficient than older types of elements.
While you may use any baking or broiling heating element in your oven, you should choose one that matches the rated wattage of your oven. A different wattage can harm your oven, or cause it overheat. The voltage and current ratings of the new heating elements can be found on the control panel of your oven. This allows you to determine the ratings and wattage of your oven.
Examine the resistance of the previous element, then compare it to the wattage rating of the new element. The greater the resistance, the more power an oven element uses.
If your broiler's heating element is acting up or doesn't work at all, you should replace it as soon as possible. It's important that your oven function properly so that you can cook your most loved food items. If your oven is not working at all, or is only working intermittently, the problem could lie with another part of your oven.
Light Bulb and Assembly
The light allows you to keep an eye on your food as it cooks without opening the doors and let the heat escape. The light will also notify you when the casserole is finished. However, it's not uncommon for the light bulb to fail. This can be frustrating, but it's a relatively easy fix you can accomplish yourself. Before you begin, make sure that the breaker hasn't been tripped and that the three-prong connector remains intact.
Remove the old bulb and then look for the new bulb. You may need to search the internet for a replacement that matches the wattage and the type of oven you have. Some ovens use standard 40-watt appliance bulbs some require halogen bulbs up to 50 watts. You should consider using cotton gloves to protect the bulbs from the damage caused by oil.
Remove the glass casing from the bulb prior to replacing it. Do slowly to avoid breaking it. You'll have to remove the air from the bulb and replace it with a mixture. This will extend the filament life.
If your light bulb is always being replaced, it could be a bigger electrical issue that should be dealt with by an expert. Verify that you're using the correct oven bulb and check your Use and Care Guide to find additional troubleshooting tips. Remember to unplug the oven and shut off the power before beginning any repairs. This will keep you from suffering an electric shock.
Vent Tube
The vent tube is an important 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 the vapors that are released from the oven to escape, and allows smoke to be drained away from the cooking surface. It is necessary to ensure the proper operation of any electric or gas oven.
Vents for ovens can become clogged or blocked by several factors. Accidental spills or splatters may leave sticky remnants in oven vents. They may attract dust, debris and other contaminants that can cause clogs in the course of time. ovens and hobs and oil particles may become airborne and settle on the vents, too. Other environmental factors, like construction and kitchen renovations can introduce dust into the vents. This can cause clogs.
Based on the model of the oven the vent tube may include a spreader, the fill tip 12, and the bottle guide 20 which are incorporated into the pipe 32. The bottle guide 20 may have a tapered edge that complements the tapered inside edge of the spreader. This allows the vent tubes to slide effortlessly into various sizes and shapes of bottle necks.
A blocked vent tube may cause a reduction in pressure inside the enclosure, which can cause a downdraft that pulls exhaust backwards and then down the vent, causing damage to the oven components. Consult a professional if think your vent pipe might be blocked or clogged. They will determine the cause and offer suggestions on how to clean or clean the vent.
