How to Repair Common Oven Parts

The oven is an appliance used in kitchens that is used to cook food. The heat generated by the oven sterilizes food items and kills the majority of micro-organisms that are present in them.

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

Thermostat

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

The oven thermostat is a small strip made of two different metals that are connected. When heated to a certain temperature, the two metals expand and bend at different rates. This creates an electrical circuit. When the metal in your thermostat reaches the temperature that you set on the control panel it will turn off the heating element's power. As the oven cools the bimetallic strips expand, re-establishing circuit and activating the heating element. This cycle is repeated continuously to ensure that the oven remains at a constant temperature.

The oven must be disconnected and all screws removed in order to determine the problem with the thermostat. 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 properly and doesn't need to be changed.

If the multimeter isn't reading anything at all, then the thermostat is defective and needs to be replaced. Cooker Spare Parts recommends that you replace the thermostat with a fresh one of the same type as the one you have. The thermostats are available for purchase at a reasonable price on the internet or in a Kitchen Convenience goods shop.

Bake Element

The bake element is essential to the operation of your oven. It generates heat that lets it cook food. 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 under the floor.

In general oven heating elements are made up of high-resistance elements such as nickel-chromium. They work by converting electrical energy into heat via the process of resistance, which then radiates through the oven interior to raise the temperature to the desired temperature to cook various types of food.

When you turn on the oven, the heating elements begin to generate heat by the high-voltage electric current flowing across the metal's surface. The element is a ribbon or coil (straight or corrugated) of wire, and as the electric current passes through it, it starts to heat up. The element will glow red hot when it reaches the desired temperature.

The baked element is the primary source of heat in most oven functions. It's usually located in the bottom of the oven and is also used to perform the self-cleaning function in many automatic oven models. When it starts to get hot you may find that your oven isn't able to warm as quickly or your food isn't fully cooked.

To determine if you have a functioning oven baking element connect your multimeter to its red and black ports, and then place the probes made of metal against each other on the opposite side of the element. The other end of the baking element against one terminal and place your hand on it. If the element feels warm, remove it and test it again. If it's not, take off the element and try again.

Broil Element

The broil element, usually located on the top of your cavity allows high-temperature heat to brown or char foods. The broil setting in your oven is an excellent option for quickly searing meat or vegetables, crisping them up, reheating lasagna or caramelizing the top of the casserole.

The broiler heating element is comparable to the bake element in that it converts electrical energy by resistance into heat. It is made up of an inner core made up of metal wires, wrapped in an insulating, expanded material called perlite. The core of the element is covered with an outer layer of stainless steel to protect the wires against direct contact with the oven. The three-layer design helps to reduce the temperature of the broil element, making it more secure than older designs.

While you are able to use any baking or broiling heating element in your oven hob, you should select one that is compatible with the rated wattage of your oven. Using a different wattage can cause damage to your oven or cause it to overheat. You can determine the power of your oven as well as the rating of the new heating element by looking at their voltage and current ratings on the control panel of your oven.

Examine the resistance of your old element, and then compare it to the wattage ratings of the new one. The greater the resistance, the more the power that an oven element draws from.

Replace the broiler element as soon as possible If it's not functioning or if it's acting up. Your oven must work properly for you to to cook your favorite foods. If your oven doesn't work in any way, or just intermittently then the problem may be a problem with a different component.

Light Bulb and Assembly

The light lets you monitor your food while it cooks, without opening the door and letting heat escape. The light also lets you know when your casserole is ready. It's not uncommon for the light bulb to go out. This can be very frustrating, but it's a relatively easy repair that you can tackle yourself. Before you begin, be sure that the breaker hasn't been tripped and that the three-prong connector is intact.

First, take out the light bulb that was in use and locate the new one. You may need to search the internet for the right replacement bulb that is compatible with the wattage of your oven. Some ovens hobs utilize standard appliances with bulbs that run at 40 watts, while others need a halogen lamp up to 50 watts. Be aware that the oils from your hands can cause damage to a halogen bulb, so you should use cotton gloves when handling it.

Before you put the new bulb in place 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. Then, you'll have to eliminate the air inside the bulb and fill it with a mixture of gases. This will ensure a longer filament life.

If your bulb keeps blinking it could be an electrical problem that requires an expert to fix it. Double check that you are using the correct oven bulb and check your Use and Care Guide for more troubleshooting advice. Make sure to unplug the oven and shut off the power prior to beginning any repairs. This will keep you from suffering an electric shock.

Vent Tube

The vent tube is a vital oven component that allows for a small airflow 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 the vapors to escape from the oven, and smoke to be drained from the cooking surface. It is essential for efficient operation of any electric or gas oven.

Oven vent tubes can become clogged or blocked by several reasons. Accidental spills or splatters can leave sticky residues on oven vents. They may draw in dust, debris and other contaminants that can cause obstructions over time. Grease and oil may also become airborne and then settle around vents. Other environmental factors, such as kitchen renovations and construction work, could introduce dust or other pollutants into the vents, leading to clogs or blockages.

Depending on the model of the oven the vent tube may include a spreader 46 and the fill tip 12, and a bottle guide 20 that are integrally formed into the pipe 32. For instance the bottle guide 20 could have a tapered outer surface that compliments the complementarily tapered inner surface of the spreader 46. This allows the vent tube to be effortlessly inserted into different sizes and forms of bottle necks.

A clogged vent tube can cause a loss in pressure inside the enclosure, which could cause an exhaust downdraft, which pulls the exhaust backwards and down the vent, causing damage to the oven components. If you suspect that your vent tube is blocked or blocked, consult a professional for help. They will identify the problem and provide suggestions on how to clear or clean the vent.
