How to Repair Common Oven Parts

Ovens are a common kitchen appliance used to cook food. The heat produced by the oven sterilizes food items and kills the majority of micro-organisms in them.

All bakers need an accurate oven thermometer. Knowing how your oven works can help you improve your baking cooking, roasting and cooking skills. It can also help you avoid those hot spots that can cause damage to cakes, cookies and baked items.

Thermostat

The thermostat is a crucial part of your oven. It is used to ensure that the temperature of food is in line with the temperature that you set on the control panel. It could be a problem, just like any other sensor or switch that is electro-mechanical. The oven and hob could overheat or underheat, or not maintain the temperature you have set.

The oven thermostat is basically an extremely small strip of two different metals joined. When heated the different metals expand and flex at different rates, creating or breaking 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 down the bimetallic strip expands, re-establishing the circuit and activating the heating element. This process is repeated repeatedly to ensure that the oven remains at a constant temperature.

You'll need the oven disconnected and all screws removed in order to determine the problem with the thermostat. If you have a multimeter (which is a device that analyzes the electrical current) set it to the ohms setting and then test the thermostat. If the multimeter reads zero or close to it then the thermostat is working correctly and doesn't need to be replaced.

If the multimeter doesn't read anything, then the thermostat is not working properly and requires replacement. Cooker Spare Parts recommends that you replace the thermostat with a fresh one that is the same model as the one you have. The thermostats are sold at a reasonable cost online or at a kitchen products shop.

Bake Element

The bake element is vital to the operation of your oven. It provides heat that lets it cook food items. It's a simple element that transforms electricity into high temperatures for baking, roasting and broiling. Electric ovens and ranges usually include heating elements that can be exposed or hidden beneath the floor.

Generally, oven heating elements are constructed from high-resistance materials like nickel-chromium alloy. They work by converting electrical energy into heat through the process of resistance which radiates outwards into the oven's interior, causing it to increase the temperature to the desired degree to cook different kinds of foods.

When you start the oven the heating elements begin 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 begins to get hotter. When the element reaches its desired temperature, it starts to shine red hot.

The baked element is the main source of heat in most oven functions. It is typically located at the bottom of the oven. Many automatic oven models also use it to clean themselves. You might notice that the oven doesn't warm up as quickly, or that your food isn't fully cooked.

Plug your multimeter in to its red and black ports. Then, you can press the metal probes on one side of the device against each other. The other end of the element on one terminal and place your hands on it. If the element feels warm, take it off it and try testing it again. If not, take it off and try again.

Broil Element

The broil element, usually located on the top of your cavity allows high-temperature heat to cook or char food items. Broil settings in ovens are an excellent way to quickly cook meat, crisp vegetables, reheat lasagna or caramelize 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 consists of an inner core of wires made of metal wrapped in insulating expanded perlite material. The inner core is wrapped in an outer layer of stainless steel to protect the wires from direct contact with the oven. The three-layer structure reduces the temperature of the broil element making it more durable and safer than older types of elements.

While you can use any baking or broiling heating element in your oven, it is important to choose one that matches the wattage that is recommended for your oven. A different wattage could damage your oven or cause it to overheat. You can determine the power of your oven and the rating of the new heating element by checking their voltage and current ratings on the oven's control panel.

You should also check the resistance of your old element and compare it with the power of the new broiler heating element. The higher the resistance, the more power an oven element uses.

If your broiler heating element is not working or [Redirect Only] functions at all, you should replace it immediately. It's important that your oven function properly so that you can cook all of your favorite food items. If your oven isn't functioning at all, or is only working intermittently, the issue could be in a different area of your oven.

Light Bulb and Assembly

The light allows you to keep an eye on your food as it cooks without opening the door and let heat escape. The light also alerts you when the casserole is ready. It's not unusual for the bulb to die. It can be quite frustrating, but you can fix it yourself. Before you begin, be sure that the breaker hasn't tripped and that the three-prong connector is intact.

First, remove the old light bulb and find the new one. You may have to look online for a replacement bulb that is compatible with the wattage and model of oven you have. Some ovens utilize standard appliance bulbs that run at 40 watts some require a halogen lamp up to 50 watts. Consider using cotton gloves to shield the halogen bulbs from damage caused by oil.

Before you place the new bulb in it is important to first remove it from its glass casing. It is important to take this step slowly to ensure that you don't damage it. You'll have to remove the air from the bulb and replace it with an appropriate mixture. This will prolong the lifespan of the filament.

If your light bulb is always being replaced, it may be a larger electrical issue that must be addressed by a professional. Make sure you're using the correct oven bulb and check your Use and Care Guide for additional troubleshooting tips. Make sure to unplug the oven and shut off the power before you start any repairs. This will protect you from electric shock.

Vent Tube

The vent tube is an important oven part as it allows for a small amount of airflow to be created inside the cavity. This allows the bake element to circulate heat throughout the oven, ensuring that the temperature is evenly dispersed.

It also allows the vapors that are released from the oven to escape, and allows smoke to be removed from the cooking surface. It is crucial for the proper operation of any gas or electric oven.

Oven vent tubes can become blocked or clogged due to a variety of factors. Accidental spills and splatters from high-quality Cooking appliances can leave sticky residues on oven vents, which could attract dust and other debris that could eventually cause clogs or blockages over time. Oil and grease can also become airborne and then settle around vents. Other environmental factors, like kitchen renovations hob and oven construction work can bring dust or other contaminants into the vents, resulting in obstructions or clogs.

Based on the model of the oven, the vent tube can comprise a spreader 46, a fill tip 12, and an a bottle guide 20 that are incorporated into the pipe 32. For example the bottle guide 20 could have a tapered outer surface which is in harmony with the tapered inside of the spreader 46 to allow the vent tube to be easily inserted into different sizes and designs of bottle necks.

A clogged vent tube can cause a reduction in pressure inside the enclosure which can lead to an exhaust downdraft, which pulls the exhaust backwards and then down the vent, damaging the oven components. Consult a professional if you believe that your vent could be blocked or clogged. They will determine the cause and offer suggestions for removing or cleaning the vent.
