How to Repair Common Oven Parts

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

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

Thermostat

The thermostat is among the most important parts of your oven, assisting to ensure that the temperature of your food is exactly what you've set in your control panel. Unfortunately, like any other electro mechanical switch or sensor, it can sometimes have problems that result in the oven going over heat or under heat, or just not be able to keep the temperature at what you've set.

The oven thermostat is basically a small strip made of two different metals bonded together. When heated the different metals expand and bend at different rates, creating or breaking an electrical circuit. When the metal in your thermostat reaches the temperature that you have set on the control panel it will shut off the power to the heater. As the oven cools down the bimetallic strip expands to re-establish the circuit before activating the heating element. This cycle is constantly repeated to ensure that the temperature remains constant in your oven.

The oven must be disconnected and all screws removed to identify a thermostat problem. If you have a multimeter (which is a tool that detects the electrical current), set it to the ohms level and then test the thermostat. If the multimeter reads 0 or very close to it then the thermostat is functioning properly and doesn't require to be replaced.

If the multimeter doesn't read anything at all, then the thermostat is not working properly and needs to be replaced. Cooker Spare Parts recommends that you replace the thermostat with a fresh one of the same kind that your old one. The thermostats are sold at a reasonable price online or in a kitchen products shop.

Bake Element

ovens and hobs uk are not complete without the bake element which provides heat to make your oven cook food. It's a small component that turns electricity into the high temperatures required for baking, roasting, and broiling. Electric ovens And hobs uk and ranges usually include heating elements that can be either exposed or hidden under the floor.

The majority of oven heating elements are constructed of high-resistance materials such as nickel-chromium alloy. They convert electricity into heat via resistance. The heat then radiates through the oven's interior to attain the temperature required for cooking different types foods.

When you switch on your oven, the heating element begins to work by generating heat through the high-voltage electricity flowing across its metal surface. The element is a ribbon or coil (straight or corrugated) of wire, and when the electric current passes through it, it starts to increase in temperature. The element will appear red hot when it reaches the desired temperature.

The baked element is the primary source of heat in all oven functions. It's usually found at the bottom of the oven and is used for the self-cleaning feature in many automatic oven models. If it starts to burn out you may be noticing that your oven doesn't warm as quickly or your food is not cooked through completely.

Plug your multimeter in to its black and red ports. Then, touch the probes made of metal on one side of the element against each other. Place the other end of the baking element against one terminal and place your hands on it. If the element feels warm, remove it and test it again. If not, take it off and try again.

Broil Element

The broil element is usually located in the top of the oven and can provide high heat like a grill to cook or brown food. The oven's broil setting is an excellent way to quickly grill 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 by the process of resistance. It is comprised of an inner core made up of metal wires, which are wrapped in an insulating and expanded product called perlite. The inner core is then encased in an outer layer of stainless steel, which protects the wires from direct contact with the oven. The three-layer structure reduces the broil element's temperature making it safer and more efficient than the older designs of elements.

You can use any heating element you want to use for baking or broiling in your oven. However, it is important to select one that matches the wattage of your oven's rating. A different wattage could 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.

Verify the resistance of the previous element, and then compare it to the wattage rating of the new one. The higher the resistance, the more energy an oven element consumes.

If your broiler heating element is not working or functions at all, you should replace it right away. It is essential that your oven function properly so that you can cook all your favorite foods. However, if your oven isn't functioning in any way or only intermittently, the problem could be in a different area of your oven.

Light Bulb and Assembly

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

Remove the old bulb and then look for the new bulb. You may have to look online for a replacement that matches the wattage and type of oven you have. Some ovens have standard appliance bulbs that run at 40 watts some require lamps that are halogen up to 50 watts. Be aware that the oil in your hands could damage a halogen bulb, so consider using cotton gloves when handling it.

Remove the glass casing from the bulb prior to replacing it. It's crucial to 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 a mixture of gases. This will ensure a longer lifespan for the filament.

If your light bulb is constantly running out, it could be an electrical issue that requires an expert to fix it. Make sure that you're using a correct bulb for your oven and consult your Use and Care Guide for more troubleshooting tips. 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 being shocked by electricity.

Vent Tube

The vent tube is a crucial oven element because it allows a small amount of airflow to flow inside the cavity. This allows the bake-element to circulate heat throughout the oven, making sure that the temperature is evenly distributed.

It also allows the vapors that are released from the oven to escape as well as allows smoke to be drained away from the cooking surface. It is vital for the proper operation of any gas or electric oven.

Vents in best ovens can get blocked or blocked due to several reasons. Accidental spills and splatters from cooking can leave sticky residues on oven vents, which can draw dust and other debris that could eventually cause obstructions or blockages in the course of time. Grease and oil particles may become airborne and settle around the vents, as well. Other environmental factors, like kitchen renovations and construction work can introduce dust or other contaminants into the vents, which can cause obstructions or clogs.

Depending on the model of the oven the vent tube could include a spreader and the fill tip 12, and a bottle guide 20 that are integrally formed into the pipe 32. For example, 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 inserted into different sizes and forms of bottle necks.

A blocked vent tube could cause a loss in pressure inside the enclosure which can lead to an updraft that pulls exhaust forward and down the vent, causing damage to oven components. If you suspect that the vent tube in your oven is clogged or blocked, consult an expert for assistance. They will identify the problem and offer suggestions on how to clean or clean the vent.
