How to Repair Common Oven Parts

Oven is an appliance in the kitchen that is used to cook food. The heat from the oven sterilizes food items and kills the majority of microorganisms.

All bakers need an accurate oven thermometer. Understanding how your oven functions will improve your baking, roasting and cooking skills. It can also help you avoid those hot spots that can ruin cakes, cookies and baked goods.

Thermostat

The thermostat is an essential element of your oven. It helps to ensure that the temperature of food matches the temperature you have set on the control panel. As with any electronic mechanical switch or sensor, it can sometimes have problems that can cause the oven to over or under heat, or just not be able to keep the temperature at what you've set.

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

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

If the multimeter does not show anything, the thermostat is faulty. It is time to get it replaced. Cooker Spare Parts suggests that you replace your thermostat with one of the same type as the old one. These thermostats are available at a reasonable price on the internet or in the kitchen store.

Bake Element

Ovens aren't complete without the bake element which provides heat to make your oven cook food. It's a basic component that turns electricity into the high temperatures required for baking, roasting and broiling. Electric ovens and ranges usually contain heating elements, which are either visible or hidden beneath the floor.

The majority of oven heating elements are constructed of high-resistance materials such as nickel-chromium alloy. They work by converting electricity into heat via resistance. The heat then radiates through the interior of the oven to reach the desired temperature to cook various types of food.

When you turn on your oven the heating element starts to work by generating heat through the high-voltage electricity that flows across its metallic surface. When electricity is flowing through it, the element heats up. The element will turn red hot when it is at the desired temperature.

The baked element is the main source of heat for the majority of oven functions. It's typically located in the bottom of the oven and is also used to clean the oven in a variety of ovens that are automatic. If it starts to get hot you may find that your oven isn't able to heat up as fast or that your food isn't fully cooked.

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

Broil Element

The broil element is usually located at the top of the oven cavity and provides the same high temperature as grills to roast or grill food items. The oven's broil setting is ideal for quick grill meat or crisp vegetables, to heat up lasagna, or caramelize the topping of the casserole.

Similar to the bake element the broiler heating element transforms electrical energy into heat via the process of resistance. It is composed of an inner core made up of metal wires, which are wrapped in an insulating expanded product called perlite. The inside of the element is then covered with an outer layer of stainless steel to shield the wires from direct contact with the oven. The three-layer design helps reduce the temperature of the broil element, making it safer than older styles.

You can use any heating element you want to use for baking or broiling in your oven. However, you should select one that matches your oven's rated wattage. Utilizing a different wattage may harm your oven or cause it to overheat. The voltage and current ratings of the new heating elements can be found on the control panel of your oven. This will allow you to examine the wattage and rating of your oven.

Examine the resistance of the old element, and compare it to the wattage rating of the new one. The greater the resistance of an oven element, the more power it draws.

If the heating element in your broiler is acting up or doesn't work in any way, you should replace it right away. Your oven must work properly for you to be able to cook your favorite foods. If your oven doesn't work at all, or only intermittently, then the issue could be with another part.

Light Bulb and Assembly

The oven light helps you keep an eye on your food while it cooks without opening the door and let heat escape. The light also lets you know when your casserole is ready. It's not uncommon for the light bulb to fail. This can be frustrating, but it's a relatively easy fix you can do yourself. Before you begin, be sure that the breaker isn't tripped and that the three-prong connector is intact.

First, take out the old light bulb and find the new one. You may have to search online for the right replacement bulb that is compatible with the wattage of your oven. Some use standard 40-watt appliance bulbs and others require a halogen bulb up to 50 watts. It is recommended to use cotton gloves to shield bulbs from the damage caused by oil.

Remove the glass casing of the bulb before you replace it. It's important to do this slowly so that you don't break it. After that, you'll need to eliminate the air inside the bulb and fill it with an amalgamation of gases. This will ensure a longer lifespan for the filament.

If your light bulb is always blinking, it could be a wider electrical issue that should be addressed by an expert. Make sure that you're using the right bulb for your oven, and check out your Use and Care Guide for more troubleshooting advice. Also, remember that it's recommended to unplug your oven and disconnect the power from the outlet prior to you start any repair. This will prevent you from suffering an electric shock.

Vent Tube

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

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

Vents for ovens can become blocked by various reasons. Accidental spills and splatters during cooking can leave sticky residues on the oven and hob vents, which attract dust and other debris that can eventually cause clogs or blockages over time. Oil and grease particles can be blown into the air and settle around the vents, too. Other environmental factors, like construction and kitchen renovations can cause dust to enter the vents. This can cause clogs.

Depending on the oven model the vent tube may comprise the bottle guide 20 or spreader 46 as well as a fill tip 12 that are integrally formed with the pipe 32. The bottle guide 20 could have a tapered outer edge that is complemented by the tapered inner edge of the spreader to allow the vent tubes to slide effortlessly into various sizes and shapes bottle necks.

A blocked vent tube could cause a loss in pressure inside the enclosure, which can cause an updraft that pulls exhaust forward and down the vent, causing damage to the oven's components. If you believe that your vent tube is clogged or blocked, oven Hob consult an expert for assistance. They will diagnose the problem and provide recommendations for removing or cleaning the vent.
