How to Repair Common Oven Parts

The oven is a Kitchen Renovation appliance that is commonly used to cook food items. The heat generated by the oven sterilizes food and kills most of the micro-organisms that are present in them.

An accurate oven thermometer is essential for all bakers. Understanding how your oven functions can help you improve your baking cooking, roasting and cooking abilities. It can also help you avoid those hot spots that can cause damage to cakes, cookies and baked goods.

Thermostat

The thermostat is among the most vital components of your oven, helping to ensure that the temperature of your food is exactly what you've set on the control panel. As with any electro mechanical switch or sensor it may have issues that can cause the oven to over or under heat, or simply not be able to maintain the temperature you've set.

The oven thermostat is a small strip made of two different metals connected. When heated to a certain temperature, the two metals expand or 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 shut off heating element's power. As the oven cools the bimetallic strips expand, re-establishing circuit and turning on heating element. This process is repeated over hob and oven over to ensure a constant temperature in your oven.

To determine if there is a issue with the thermostat, you'll have to remove the oven and ensure that all of the screws holding it in place have been removed. If you own a multimeter (which is a tool that measures the electrical current), set it to the ohms level and then test the thermostat. If the multimeter reads zero or very close to it then the thermostat is operating properly and doesn't need to be replaced.

If the multimeter isn't reading anything, then the thermostat is defective and requires replacement. Cooker Spare Parts suggests that you replace your thermostat with a similar model as the one you have. These thermostats are available at a reasonable cost on the internet or in a kitchen goods shop.

Bake Element

The bake element is crucial to the operation of your oven. It generates heat that allows it to cook food. It's an easy component that converts 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.

Generally, oven heating elements are made from high-resistance materials like nickel-chromium alloy. They convert electrical energy into heat through the process of resistance which radiates outwards into the oven's interior to raise the temperature to the desired level to cook different kinds of food.

When you switch on the oven the heating elements begin to produce heat through the high-voltage current flowing across the surface of the metal. The element is a coil or ribbon (straight or corrugated) of wire. When the electric current passes through it, it starts to heat up. When the element reaches its temperature, it starts to glow red hot.

The baked element is the main source of heat in all oven functions. It's usually located at the in the bottom of the oven. Many ovens with automatic heating also have it for self-cleaning. You might notice that your oven doesn't get hot as fast, or that your food isn't cooked completely.

Plug your multimeter in to its red and black ports. Then, you can press the probes made of metal on one end of the device against each other. Place the other end against one of its terminals and place your hand on it to test if the element is warm to the contact. If not, remove it and try again.

Broil Element

The broil element is usually located in the top of the oven cavity and provides high-temperature heat similar to a grill to brown or char food items. Broil settings in ovens are an excellent way to quickly cook meat crisp vegetables, heat lasagna, or caramelize the topping of the casserole.

The broiler heating element is similar to the bake element in that it converts electrical energy through resistance into heat. It is comprised of an inner core comprised of wires made of metal, encased in an insulating, expanded material called perlite. The inner core of the element is covered with an outer layer of stainless steel to shield the wires from direct contact with the oven. The three-layer structure helps lower the temperature of the broil element which makes it safer and more efficient 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 is in line with the wattage rating of your oven. A different wattage may cause damage to your oven or cause it to overheat. You can check the power of your oven and the rating of the new heating element by examining their current and voltage ratings on the oven's control panel.

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

Replace the element in your broiler immediately if it is not working or is acting up. It's important for your oven and hob to function properly so that you can cook all your favorite food items. If your oven does not operate in any way, or just intermittently then the problem may be with another part.

Light Bulb and Assembly

The light lets you keep an eye on your food while it cooks without opening the door and let the heat escape. The light will also notify you when the casserole has been cooked. It's not uncommon for the bulb to go. This can be frustrating, but it's a relatively easy fix you can tackle yourself. Before you begin, be sure that the breaker hasn't 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 have to search online for a replacement that is compatible with the wattage and model of your oven. Some ovens use standard appliance bulbs of 40 watts and others require an halogen lamp that can reach 50 watts. It is recommended to use cotton gloves to shield bulbs from the damage caused by oil.

Before you place the new bulb in it is important to first take it out of its glass casing. 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 an amalgamation of gases. This will extend the lifespan of the filament.

If your bulb keeps going out, there could be a wider electrical issue that must be handled by an expert. Make sure you're using the correct oven bulb hobs and ovens look over your Use and Care Guide to get more help in troubleshooting. Also, remember that it's a good idea to unplug your oven and disconnect it from the outlet before you start any repair. This will help prevent suffering an electric shock.

Vent Tube

The vent tube is an essential oven component that permits a tiny airflow inside the cavity. This allows the bake element to circulate heat throughout the oven, ensuring that the temperature is distributed evenly.

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

Oven vent tubes may become clogged by various reasons. Accidental spills or splatters may leave sticky residues in oven vents. These can attract dust, debris and other contaminants that could cause obstructions in the course of time. Oil and grease particles can be blown into the air and settle around the vents, as well. Other environmental factors like construction and kitchen renovations can create dust in the vents. This can cause clogs.

Based on the type of the oven, the vent tube can include a spreader 46, the fill tip 12, and the bottle guide 20 which are incorporated into the pipe 32. For example the bottle guide 20 could have a tapered outer layer that is complemented by the tapered inside of the spreader 46. This allows the vent tube to be effortlessly placed into various sizes and shapes of bottle necks.

A blocked vent tube could 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's components. Consult a professional if you think your vent pipe may be clogged or blocked. They will diagnose the problem and offer suggestions for removing or cleaning the vent.
