Convection Oven

What are the parts of a convection oven?

Are you looking to replace your oven? For those of us who use an oven regularly we get habituated with the settings and working conditions of the oven. We know exactly which temperature knob is slightly rusted, where to place what item when putting it inside the oven and many other things. If this is the first time that you are looking to buy your own oven then not knowing what to look for can be daunting. You can look into the quality of these machine parts when buying your new oven.

 Magnetron:

The cracking of magnets, burning out of terminals, burned antennae, a loose connection, resistance continuity are among the most common reasons for a magnetron to stop working. A burned antenna can cause resistance in the stream of electrons thus obstructing the well-functioning of the oven.

 Air Filter:

Ovens have range hood filters- the metal grill that can be found attached to the bottom of your range hood. In some cases, the filter can slide off easily but you might also need the help of a screwdriver to access it. Cleaning the filter by immersing it in hot, soapy water for about twenty minutes can be a good maintenance trick. With the help of a nonabrasive brush or scrubber, you can remove any remaining grease residue from the Oven Range Air filter.

Light Bulb:

Ovens require special light bulbs. These are unique as they are built in a way to prevent corrosion on the base of the bulb. Higher temperature solder formulations are used to allow the bulb to function smoothly even at temperatures as high as 1000F (especially for self-cleaning ovens). These bulbs have glass that is thicker and thus it is less likely to break during installation or during removal as you can only access the crown of the bulb in your cleaning process. It is important to make sure that the bulb is durable rather than focusing on its brightness.

 Door Switch:

These switches are only an inch long and are mostly black in colour. They have metal prongs, also known as terminals that extend outwards from the body of the switch. These switches are attached to a bracket near the door latch of the oven. Most microwaves and ovens have three of four door switches. For caution, you must remove all wiring harness leads from around the switch’s terminals.

Waveguide Cover:

Its main job is to transmit microwave radiations. This part of the oven prevents steam and food particles from interacting with the electrical components within the oven. Its main purpose is to prevent food particles from entering the electrical cavity. The waveguide cover is located on the same side as the control panel. It is a thin sheet that looks like plastic or even cardboard at times. The cover is quite brittle and can reak if one does not handle it with care.

 Grill: 

The grill is a device used to cook heat by heating it from below. In an oven, the grill works perfectly as the temperature gets evenly distributed as the now enclosed compartment begins to resemble as cooker. Such grills are often used for outdoor cooking. In order to keep the grill burning in an oven, it is recommended to keep the oven door slightly ajar. This allows the flow of air and also lets the heat from escaping the oven. Extra heat can trigger its safety mechanism and automatically shut down the oven.

Switch Bracket:

These are specifically designed by manufacturers as per the model. You can purchase these with the oven or separately. They vary in configuration as they have to be designed to properly accommodate hanging the oven securely.

Transformer

Most transformers used in ovens are simple, easy to build, robust, cheap and even easy to install. A typical oven transformer has secondary windings. One winding provides around 3.1 to 3.2 volts while the high voltage provides around 1800-2800 volts. The purpose of this transformer is to generate very high-powered high voltage to energize the magnetron. Some of its power can also be stored in capacitors. When not used carefully, this can be quite dangerous.

Door Latch

The door latch is connected to the door switch that prevents the oven from operating even when the door is left open. This latch activates the door switch when the oven door is closed. You can use a few lubricants and a few hand tools to adjust your own door latch. It is a mechanical fastener that joins two or more objects or surfaces while allowing their regular separation. They range in complexity from flexible one-piece flat springs of metal or plastic etc.

Capacitor

It stores excess electrical energy from the thermostat preventing wastage and danger. You must check the capacitor in case your oven has not been heating well. You can find replacement parts for your capacitor and other oven parts at PartsFe.

Membrane

A possible cause for microwave buttons not working could be an issue with the membrane switch. The membrane switch is more commonly known as the touchpad and has a few soft touch electrical switches. There is a certain conductive coating on the touchpad which can go defective with repeated usage. To check this issue and to resolve it, you will need to unplug the appliance and remove the cabinet. Check the membrane switch using a multimeter for continuity.

Control Board

Control board is the part of the oven that is responsible for generating a low voltage which is in turn supplied to the membrane switch. In case the control board does not generate a low voltage signal then you may need to replace it. To replace the unit, you will first have to disconnect the main power supply and then remove the cabinet and the assembly.

Fuse

Electric ranges include a fuse in the 120-volt circuit that operates such items as oven and stove top lights, the electric clock, convenience outlets, etc.
