How to Repair Common Oven Parts

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

A precise oven thermometer is essential for all bakers. Knowing how your oven functions will help improve your baking and roasting skills and eliminate those frustrating hot spots that wreak havoc with cookies, cakes and other baked products.

Thermostat

The thermostat is among the most crucial components of your oven uk, helping ensure that the temperature of your food is exactly the temperature you've set on your control panel. It can be problematic, just like any other switch or sensor that is electro-mechanical. The oven may overheat or underheat, or simply not maintain the temperature you set.

The oven thermostat is basically tiny strips of two different metals that are bonded together. When heated, the metals expand or flex at different rates. This creates an electrical circuit. When the thermostat's metal reaches the temperature you've set on your control panel, it shuts off the power to the heating element. When the oven cools down, the bimetallic strip contracts, re-establishing the circuit and turning on the heating element. This process is repeated over and over to maintain a constant temperature within your oven.

The oven must be disconnected and all screws removed in order to determine the issue with the thermostat. 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 displays zero or close to zero, the thermostat is functioning properly and doesn't need to be changed.

If the multimeter isn't reading anything, then the thermostat is not working properly and requires replacement. Cooker Spare Parts recommends that you replace the thermostat with a new one of the same kind as your old one. The thermostats are available for purchase at a reasonable cost on the internet or in a kitchen products shop.

Bake Element

ovens and hobs can't be complete without the bake element which provides heat to make your oven cook food. It's a simple component that transforms electricity into high temperatures for baking, roasting and broiling. Electric best ovens and Hobs uk and ranges often include heating elements that can be either exposed or hidden beneath the floor.

In general, oven heating elements consist 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's interior to raise the temperature to the desired temperature to cook various types of foods.

When you switch on the oven the heating elements start to produce heat through the high-voltage current that flows across the surface of the metal. The element is a ribbon or coil (straight or corrugated) of wire, and when the electric current flows through it, it starts to increase in temperature. The element will glow red hot when it is at the desired temperature.

The baked element is the primary source of heat used in most oven functions. It's usually located at the in the bottom of the oven. Many automatic oven models also use it for self-cleaning. You may notice that the oven does not get hot as fast or that your food isn't cooked to perfection.

Plug your multimeter in to its black and red ports. Then, touch the metal probes on one end of the element to each other. Set the other end of the probe against one of its terminals, and Best place to buy oven and hob your hand on it to test whether the baking element is warm to the touch. If not, take it off and try again.

Broil Element

The broil element, which is usually located on the top of your cavity, offers high temperatures to brown or char the food. The oven's broil setting is a great way to quickly cook meat crisp vegetables, heat lasagna or caramelize 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 composed of an inner core comprised of metal wires, wrapped in an insulating, expanded material called perlite. 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 reduce 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, you should choose one that matches the wattage rating of your oven. A different wattage could damage your oven or cause it to overheat. You can verify the wattage of your oven and the rating of the new heating element by looking at their voltage and current ratings on the oven's control panel.

You should also check the resistance of your old element and compare it to the power of the new broiler heating element. The higher the resistance of an oven element the greater power it draws from it.

If your broiler heating element is malfunctioning or isn't working at all, you must replace it as soon as possible. Your oven must work properly to be able to cook your favorite foods. If your oven doesn't operate at all, or only intermittently, then the issue could be a problem with a different component.

Light Bulb and Assembly

The oven light helps keep an eye on your food cooking without having to open the door to let heat escape. The light will also notify you when the casserole has been cooked. It's not unusual for the light bulb to fail. It can be a hassle however, it's an easy repair that you can tackle yourself. Before you begin, be sure that the breaker hasn't tripped and that the three-prong connector remains intact.

Remove the old bulb and then find the new one. It is possible to search the internet for the right replacement bulb that is compatible with the wattage of your oven. Some ovens and hobs use standard appliance bulbs that run at 40 watts and others require lamps that are halogen up to 50 watts. Consider using cotton gloves to shield bulbs from damage caused by oil.

Remove the glass casing of the bulb prior to replacing it. Do slowly to avoid breaking it. Then, you'll have to eliminate the air inside the bulb and fill it up with a mixture of gases. This will ensure a longer lifespan of the filament.

If your bulb keeps blinking it could be due to an electrical issue that needs an expert to fix it. Make sure you're using the correct oven bulb and look over your Use and Care Guide for more help in troubleshooting. And remember that it's always recommended to unplug your oven and disconnect the power from the outlet prior to you begin any repair. This will keep you from suffering an electric shock.

Vent Tube

The vent tube is a vital oven part that allows for a small airflow 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 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 gas or electric oven.

Oven vent tubes may become blocked due to a variety of factors. Accidental spills or splatters can leave sticky residues on oven vents. They may attract debris, dust and other contaminants that can cause clogs over time. Grease and oil particles can become airborne and settle around the vents, too. Other environmental factors, such as kitchen renovations and construction work, can introduce dust and other contaminants into the vents, Best ovens and Hobs Uk which can cause obstructions or clogs.

Depending on the model of the oven the vent tube could include a spreader 46, a fill tip 12, and a bottle guide 20 that are integrally formed into the pipe 32. The bottle guide 20 can have a tapered edge that complements the tapered inside edge of the spreader. This allows the vent tubes to be placed easily into different sizes and shapes bottle necks.

A blocked or clogged vent tube could cause the loss of pressure inside the structure that surrounds it, which could result in a downdraft which pulls exhaust down vent and backwards towards the oven burners, causing damage to the oven components. If you suspect that your vent tube is clogged or blocked, contact an expert for assistance. They will diagnose the issue and provide suggestions on how to remove or clean the vent.
