5 Oven Projects That Work For Any Budget
How to Repair Common Oven Parts

Ovens are a kitchen appliance that is commonly used to cook food. The heat generated by the oven sterilizes food and kills the majority of microorganisms.

An accurate oven thermometer is an essential for bakers of all kinds. Understanding how your oven works will improve your baking and roasting skills and eliminate those frustrating hot spots that cause havoc with cookies, cakes and other baked goods.

Thermostat

The thermostat is a crucial component of your oven. It helps to ensure that the temperature of food corresponds to the temperature you set on the control panel. It could be a problem as with any other switch or sensor that is electro-mechanical. The oven can overheat or underheat, or not maintain the temperature you have set.

The oven thermostat is a small strip made of two different metals bonded together. When heated by the oven, the metals expand and bend at different rates. This creates an electrical circuit. When the metal in the thermostat attains the temperature you've set on your control panel it turns off the heating element's power. As the oven cools it expands the bimetallic strip to re-establish the circuit before turning on heating element. This process is repeated repeatedly to maintain a constant oven temperature.

To diagnose a issue with the thermostat, you'll need to unplug the oven and make sure 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, then the thermostat is working correctly and doesn't need to be replaced.

If the multimeter does not detect anything then the thermostat is not working properly. It is time to get it replaced. Cooker Spare Parts recommends that you replace the thermostat with a new one that is the same model as your old one. They are available online or at a kitchen goods store, and are available at a reasonable cost.

Bake Element

Ovens aren't complete without the bake element, which is the element that heats up to help your oven cook food. It's a small element that converts electricity into the high temperatures needed for baking, roasting, and broiling. Heating elements are usually found in electric ovens and ranges and are covered or hidden beneath the floor of the oven.

In general oven heating elements comprise of high-resistance elements such as nickel-chromium. They convert electrical energy into heat by the process of resistance, which then radiates throughout the oven interior to raise the temperature to the desired level to cook various types of foods.

When you start your oven the heating element gets to produce heat from the high-voltage electrical energy flowing across its metal 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. When the element reaches its temperature, it starts to shine red hot.


The baked element is the main source of heat for the majority of oven functions. It's usually located at the lower levels of the oven. Many automatic oven models also use it for self-cleaning. If it starts to smoke, you might be noticing that your oven doesn't heat up as fast or that your food isn't fully cooked.

To determine if you have a functioning oven baking element, plug your multimeter into its red and black ports, then touch the metal probes against each other on one side of your device. Place the other end of the baking element against one terminal and then place your hand on it. If the element feels warm, remove it and try testing it again. If it's not, take off the element and try again.

Broil Element

The broil element, which is usually found at the top of your cavity, allows high-temperature heat to cook or char the food. Broil settings in ovens are a great way to quickly cook meat or crisp vegetables, to heat up lasagna, or caramelize the topping of a casserole.

Similar to the bake element the broiler heating element converts electrical energy into heat via the process of resistance. It consists of an inner core of metal wires 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 design helps lower the temperature of the broil element, making it safer than older styles.

While you are able to use any baking or broiling heating element in your oven, make sure to select one that is compatible with the wattage that is recommended for your oven. Using a different wattage can harm your oven or cause it to overheat. The voltage and current ratings of the new heating elements are available on the control panel of your oven. This will allow you to check the power and rating of your oven.

You should also check the resistance of your previous element and compare it to the wattage of your new broiler heating element. The higher the resistance of an oven element, the more power it draws.

If the heating element in your broiler is not working or functions at all, you should replace it immediately. It's important that your oven functions properly so that you can cook all your favorite foods. If your oven doesn't work in any way, or just intermittently, the issue may be a problem with a different component.

Light Bulb and Assembly

The oven light helps keep an eye on the food as it cooks, without having to open the door and let heat escape. The light will also notify you when the casserole has been cooked. But it's not uncommon for the bulb to go out. This can be very frustrating, but it's a relatively easy repair that you can accomplish yourself. Before you begin, make sure that the breaker hasn't tripped and that the three-prong connector is in good condition.

First, take out the old light bulb and then locate the new one. You may have to search the internet to find a replacement that is compatible with the wattage and model of your oven. Some ovens use standard 40-watt appliance bulbs some require a halogen bulb that is up to 50 watts. Be aware that the oils from your hands can cause damage to a halogen bulb, so it is recommended to use cotton gloves when handling it.

Remove the glass casing of the bulb prior to replacing it. ovens hobs 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 a mixture. This will ensure a longer lifespan for the filament.

If your bulb is constantly blinking, it may be a larger electrical issue that must be handled by an expert. Be sure to double check that you're using the correct bulb for your oven and check out your Use and Care Guide for more troubleshooting advice. Be sure to unplug your 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 an essential oven component that allows for a tiny airflow inside the cavity. This permits the bake element to circulate heat throughout the oven, making sure that the temperature is evenly distributed.

It also allows vapors to be released from the oven, and smoke to be drained from the cooking surface. It is vital for the proper operation of any electric or gas oven.

Vents in ovens can get blocked or blocked due to several reasons. Accidental spills or splatters could leave sticky residues on oven vents. These can attract debris, dust and other contaminants that can cause obstructions in the course of time. Grease and oil may also be airborne and settle around vents. Other environmental factors, like kitchen and construction projects can cause dust to enter the vents. This can cause clogs.

Depending on the model of the oven, the vent tube can include a spreader 46, a fill tip 12, and the bottle guide 20 which are integrally formed into the pipe 32. For instance the bottle guide 20 might have a tapered outer surface that compliments the complementarily tapered inner surface of the spreader 46, allowing the vent tube to be smoothly fitted into various sizes and shapes of bottle necks.

A clogged vent tube can cause a loss in pressure inside the enclosure which could cause a downdraft that pulls exhaust backwards and then down the vent, damaging the oven's components. Contact a professional if you think your vent pipe may be clogged or blocked. They will diagnose the problem and provide recommendations for removing or cleaning the vent.
