How to Repair Common Oven Parts

The oven is a kitchen appliance that is typically used to cook food. The heat produced by the oven sterilizes foods and kills the majority of micro-organisms present in them.

An accurate oven thermometer is a necessity for bakers of all kinds. Knowing how your oven functions will help improve your baking and roasting skills and eliminate those frustrating hot spots that can cause havoc with cookies, cakes and other baked products.

Thermostat

The thermostat is an essential part of your oven. It helps to ensure that the temperature of food corresponds to the temperature you set on the control panel. However, just like any other electronic mechanical switch or sensor it can have issues that result in the oven going over heat or under heat, or simply not be able to keep the temperature at what you've set.

The oven thermostat is tiny strips of two different metals joined. When exposed to heat, the different metals expand and bend at different rates, electric oven creating or breaking an electrical circuit. When the metal in your thermostat reaches the temperature that you set on the control panel it will shut off heating element's power. As the oven cools, the bimetallic strips contract in a circuit, re-establishing it and activating the heating element. This process is repeated repeatedly to ensure that the oven remains at a constant temperature.

To determine if there is a problem with the thermostat you'll need to disconnect the oven and make sure that all of the screws that hold it in place have been removed. Set your multimeter to the Ohms setting and then test the thermostat. If the multimeter displays zero or close to zero, the thermostat is functioning properly and doesn't need to be changed.

If the multimeter doesn't read anything at all, then the thermostat is defective and needs to be replaced. Cooker Spare Parts recommends that you replace the thermostat with a brand new one that is the same model as the one you have. They are available through the internet or at an appliance store and are available at a reasonable price.

Bake Element

The bake element is crucial to the operation of your oven. It produces heat that allows it to cook food. It's a simple component that transforms electricity into high temperatures for baking, roasting and broiling. Electric ovens and ranges often contain heating elements, which can be exposed or hidden under the floor.

In general, oven heating elements are constructed of high-resistance materials such as nickel-chromium alloy. They work by converting electricity into heat through resistance. This heat is then radiated through the oven's interior to reach the desired temperature for cooking different types foods.

When you start your oven the heating element starts to produce heat by the high-voltage electricity that flows across its metallic surface. The element is a coil or ribbon (straight or corrugated) of wire, and when the electric current passes through it, it starts to heat up. When the element reaches its temperature it starts to shine red hot.

The baked element is the primary source of heat for most oven functions. It is usually located at in the bottom of the oven. A lot of ovens that are automated also have it to clean themselves. You may notice that your oven doesn't warm up as quickly, or that your food hasn't cooked completely.

Connect your multimeter to its black and red ports. Then, press the probes made of steel on one side of the device against each other. The other end of the baking element against one terminal and place your hand on it. If the element feels warm, remove it and try testing it again. If not, remove it and try again.

Broil Element

The broil element, which is usually found at the top of the cavity, allows high-temperature heat to cook or char food items. The broil setting in your oven is an excellent option for quickly grilling meat or vegetables, crisping them up, reheating lasagna or caramelizing the top of the casserole.

Similar to the bake element the broiler heating element transforms 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 inner core of the element is covered with a stainless steel outer layer to shield the wires from direct contact with the oven. The three-layer design helps lower the temperature of the broil element, making it more secure than the older models.

You can use any heating element to bake or broiling in your oven. However, it is important to choose one that is in line with the wattage of your oven's rating. A different wattage could cause damage to your oven or cause it overheat. The voltage and current ratings of the new heating elements can be located on the control panel of your oven. This allows you to determine the ratings and wattage of your oven.

Check the resistance of the old element, and compare it to the wattage ratings of the new one. The greater the resistance, the more power an oven element uses.

Replace your broiler element immediately If it's not functioning or if it's acting up. Your oven needs to function properly to be able to cook your favorite meals. However, if your oven isn't working in any way or only intermittently, the problem could be with a different part of your oven.

Light Bulb and Assembly

The light lets you keep an eye on your food as it cooks without opening the doors and letting heat escape. The light will also inform you when the casserole is finished. It's not uncommon for the bulb to go. It can be quite frustrating, but you can do it yourself. Before you begin, make sure that the breaker isn't tripped and that the three-prong connector stovetop remains intact.

First, remove the light bulb that was in use and find the new one. You may need to search online for a replacement bulb that matches the wattage and type of oven you have. Some ovens and hobs have normal appliance bulbs that are 40 watts in power and others require a halogen lamp up to 50 watts. Be aware that the oil in your hands can cause damage to the bulb, so it is recommended to 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 break it. Then, you'll need to remove the air from the bulb and fill it with gas mixture. This will ensure a longer lifespan for the filament.

If your bulb is constantly going out, there could be a bigger electrical problem that needs to be dealt with by an expert. Make sure you double-check that you're using the correct bulb for your oven, and check out your Use and Care Guide for additional troubleshooting suggestions. Remember to unplug the oven and shut off the power before beginning any repairs. This will keep you from suffering an electric oven shock.

Vent Tube

The vent tube is an essential oven part as it allows for Electric Oven a small amount of airflow to flow inside the cavity. This allows the bake element to circulate heat throughout the oven and ensures that the temperature is evenly distributed.

It also allows vapors to escape from the oven, and smoke to be drained from the cooking surface. It is crucial to ensure the proper operation of any electric or gas oven with hob.

Oven vent tubes may become blocked due to a variety of factors. Accidental spills or splatters can leave sticky residues on oven vents. These can attract debris, dust and other contaminates that could cause blockages over time. Grease and oil particles can become airborne and settle around the vents, and vice versa. Other environmental factors like kitchen and construction work can create dust in the vents. This can cause clogs.

Depending on the oven model the vent tube may comprise an a bottle guide 20, spreader 46 and fill tip 12 that are formed by the pipe 32. The bottle guide 20 may have a tapered edge that matches the tapered inside edge of the spreader, allowing the vent tubes to be inserted easily into different sizes and shapes bottle necks.

A clogged vent tube can cause a decrease in pressure inside the enclosure, which can lead to an updraft that pulls exhaust backwards and then down the vent, causing damage to oven components. If you suspect that your vent tube is clogged or blocked, call an expert for assistance. They will determine the cause and offer suggestions on how to remove or clean the vent.
