How to Repair Common Oven Parts
Ovens are an appliance in the kitchen that is used to cook food. The heat of the oven sterilizes food items and kills the majority of microorganisms.
A reliable oven thermometer is essential for all bakers. Understanding how your oven functions will improve your baking cooking, roasting and cooking skills. It will also eliminate those hot spots that can ruin cakes, cookies and baked items.
Thermostat
The thermostat is an essential component of your oven. It is used to ensure that the temperature of food is in line with the temperature you set on the control panel. It could be a problem as is any other sensor or switch that is electro-mechanical. The oven could overheat or underheat, or not maintain the temperature you have set.
The oven thermostat is an extremely small strip of two different metals that are connected. When heated by the oven, the metals expand or bend at different rates. This creates an electrical circuit. When the thermostat's metal attains the temperature you've set on your control panel it turns off the power to the heating element. As the oven cools, the bimetallic strips contract, re-establishing circuit and turning on heating element. This process is repeated over and over to maintain a constant temperature within your oven.
To determine if there is a problem with the thermostat, you'll need to unplug the oven and ensure that all screws that hold it in place have been removed. Set your multimeter to the Ohms setting, and then test the thermostat. If the multimeter reads zero or close to it the thermostat is working correctly and doesn't need to be replaced.
If the multimeter does not read anything, then the thermostat is faulty and must be replaced. Cooker Spare Parts suggests that you replace your thermostat with a similar type as the previous one. These thermostats are available at a reasonable price on the internet or in the kitchen store.
Bake Element
The bake element is essential for the proper operation of your oven. It produces heat that allows it to cook food. It's a small element that converts electricity into the high temperatures needed to bake, roast, and broiling. Heating elements are usually found in electric ranges and ovens, 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 materials such as nickel-chromium. They work by converting electrical energy into heat through the process of resistance which radiates outwards into the oven interior to raise the temperature to the desired temperature to cook various types of food items.
When you turn on the oven the heating elements start to produce heat through the high-voltage current flowing across the metal surface. The element is a ribbon or coil (straight or corrugated) of wire. When the electric current flows through it, it starts to heat up. The element will glow red hot when it is at the desired temperature.
The baked element is the primary source of heat for the majority of oven functions. It is usually located at lower levels of the oven. Many automatic oven models also utilize it to clean themselves. If it starts to get hot, you might be noticing that your oven doesn't heat up as fast or that your food is not fully cooked.
To check for a working oven baking element plug your multimeter into its red and black ports, and then place the probes made of metal against each other on the opposite side of your device. Set the other end of the probe against one of its terminals and place your hand on it to feel whether the baking element is warm to the touch. If not, take it off and try again.
Broil Element
The broil element, typically located at the top of your cavity, provides high temperatures to brown or char the food. The broil setting in your oven is an excellent choice for quickly searing meat, crisping vegetables, reheating lasagna, or caramelizing the top of a 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 an insulating expanded perlite material. The inner core is then encased in an outer layer of stainless steel to shield the wires from direct contact with the oven. The three-layer design can help reduce 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 in line with your oven's rated wattage. A different wattage may damage your oven, or cause it overheat. You can determine the power of your oven and the rating of the new heating element by looking at their current and voltage ratings on the control panel of your oven.
Examine the resistance of the old element, then compare it with the wattage rating of the new element. The greater the resistance of an oven element, the more power it uses.
If your broiler heating element is not working or functions at all, you must replace it immediately. Your oven must work properly to to cook your favorite foods. However, if your oven isn't working at all, or is only working intermittently, the problem could be in a different area of your oven.
Light Bulb and Assembly
The light lets you monitor the food that is cooking without opening the doors and let heat escape. The light will also notify you when the casserole has been cooked. But it's not uncommon for the light bulb to fail. This can be frustrating however, it's an simple fix that you can do yourself. Check 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 need to look online to find a replacement that matches the wattage and the type of oven you have. Some ovens have standard appliance bulbs that run at 40 watts some require an halogen lamp that can reach 50 watts. Be aware that the oil from your hands can cause damage to a halogen bulb, so you should use cotton gloves when handling it.
Remove the glass casing of the bulb before replacing it. It's important to do this slowly so that you don't fracture it. You'll then need to remove the air from the bulb and replace it with an appropriate mixture. This will provide a longer life for the filament.
If your bulb keeps blinking, it may be a larger electrical issue that must be handled by an expert. Make sure that you're using a correct bulb for your oven, and check out your Use and Care Guide for additional troubleshooting suggestions. Also, remember that best ovens and hobs uk 's an excellent idea to unplug your oven and disconnect the power from the outlet prior to you begin any repair. This will keep you from suffering an electric shock.
Vent Tube
The vent tube is an important oven part as it allows for a tiny amount of airflow to flow inside the cavity. This allows the bake element to circulate heat throughout the oven, ensuring that the temperature is evenly distributed.
It also allows vapors from the oven to escape as well as allows smoke to be drained away from the cooking surface. It is necessary for the proper operation of any gas or electric oven.
Oven vent tubes may become blocked due to many factors. Accidental spills or splatters could leave sticky remnants in oven vents. They can attract debris, dust and other contaminants that can cause clogs over time. Oil and grease can also become airborne and then settle on vents. Other environmental factors, such as kitchen construction and renovations, can bring dust and other contaminants into the vents, resulting in clogs or blockages.
Based on the oven model, the vent tube may comprise the bottle guide 20 or spreader 46 as well as a fill tip 12 that are integrally formed by the pipe 32. The bottle guide 20 may have a tapered outer edge that matches the tapered inner edge of the spreader to allow the vent tubes to be placed easily into different sizes and shapes bottle necks.
A clogged or blocked vent tube can cause a loss of pressure within the structure that surrounds it, which can create a downdraft situation that pushes exhaust down the vent and backwards through the oven burners, causing damage to the oven's components. If you suspect that the vent tube in your oven is clogged or blocked, consult a professional for help. They will identify the issue and provide recommendations for removing or cleaning the vent.
