Should I be concerned about BPA ?

I follow a lot of conversations about all things microwave and a subject that has come to the fore again recently is the worry about the need for microwave cookware being BPA free.

So what is BPA ?

BPA stands for bisphenol A. BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s.

BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles. They may also be used in other consumer goods.

Epoxy resins are used to coat the inside of metal products, such as food cans, bottle tops and water supply lines.

Some research has shown that BPA can seep into food or beverages from containers that are made with BPA. Exposure to BPA is a concern because of possible health effects of BPA on the brain, behavior and prostate gland of fetuses, infants and children. Additional research suggests a possible link between BPA and increased blood pressure.

For this reason it makes sense that when you use plastic microwave cookware to see if it is BPA free if possible.

On these 2 items from our shop you can see that they are clearly marked as BPA free:

bpa free label

this product shows that it is BPA free

However. The chances of your food absorbing any BPA is very small anyway. Even if you use plastics that are not BPA free there is only a very minuscule chance that any will be absorbed from the plastic to the food.

The chance is increased in plastics that are classed as one use plastics that get reheated that were never designed to be heated in the first place. Examples are margarine tubs or fast food takeaway containers. I would advise transferring these into at least a proper microwave container, whether it be microwave safe or even glass just to be absolutely sure.

As it happens all of the cookware we sell at www.kitchenwareonline.com is BPA free just to be sure. Although cookware doesn’t have to be marked as BPA free if it is marked as such you will be sure that BPA will never be an issue in your kitchen.

Are your air vents blocked ?

Microwave ovens run quite hot anyway but they have a cooling fan which draws cool air usually at the back of the oven.

However, if this air vent becomes blocked, which it does over a period of time. it draws in fluff which builds up like this :

Eventually the oven will not be able to draw enough cool air through the vent and the workings inside will get progressively warmer until one or more of the microwave components overheats and fails.

This particular blockage resulted in the failure of the magnetron, the device that produces the microwaves. The microwave overheated and cut out. It was repaired and it wasn’t too costly for the customer but could have been prevented completely.

Look at the back of your microwave and see where the air is drawn in and just check the condition and clean it off with a stiff brush – but not while the oven is running or the fluff will be drawn inside the oven. if it is bad then you may need to remember to check more often to save the cost of a repair.

Kitchenwareonline.com – easier to navigate

We have now started adding facets to our spare parts. When you navigate to a particular category within the catalogue a series of tick boxes will appear to help narrow down your search. Illustrated below is the Panasonic commercial microwave spares section. See how the list of Panasonic commercial models has appeared on the left. Just tick your model and the parts shown on the page will be only those suitable for that model.

This will save wading through lots of unsuitable parts not relevant.

We have added this to other sections of the catalogue including breadmaker spares, to narrow down the search to both make and model and microwave cookware to narrow down the category of cookware such as jugs or egg cookers for example.

We hope this makes life easier for you and look forward to your orders.

Don’t forget, if you cant find what you need don’t hesitate to contact us. We’ll see what we can do.

Our Online Shop – Kitchenwareonline.com

We have now published quite a few posts here. I think its time just to remind everyone about the range of products available on our online shop.

We created the shop in the first instance to make it easier for users to buy replacement accessories such as glass turntables, Roller rings, waveguide covers and bulbs. The sort of things that often fail and can fairly readily be replaced at home.

There are so many different types of all of the above items that we decided the best way to build the site was to incorporate the ability to search by make and model. Now, you can easily narrow down by the make and then the model of your microwave the spares and accessories that we offer to fit your microwave.

If you want to try that click here to start the search by going first to the brand – or make of your microwave.

Listings by manufacturer

You will then get several pages (in some cases many) of model numbers. Find yours, but don’t worry if the suffix or letters after the model number are not there. They often only indicate the colour of the oven- the spares we sell are non colour specific.

Listings by category

If you want to browse the shop click on the shop button and the main category headings are listed. Microwave spares, Bread maker spares, New appliances etc. Simply click on these to go to the section or sub category.

A built in microwave will almost definitely cheaper to repair than to replace

We repair a great number of built in microwave ovens. For many years now new kitchens have had the option to have a microwave or combi oven fitted within the wall units to keep the worktop clear.

The microwave tends to be based around a free standing microwave so from our point of view will be just as easily repaired – once it is out of the unit. To that end if you can remove it from the housing why not bring it into our shop to save the call out. The repair will be even cheaper.

The unit often has the trim pieces top and bottom fitted to the oven. if you can see screws then they are probably just locating the oven within the housing. It is usually sat on a plynth to centralise it in the housing and more often than not held in mainly by gravity.

Like a lot of built in appliances, it will be a lot easier and no doubt cheaper to repair the microwave than to have to find a replacement that is the same design and size.

As you can see from the photos here of a typical example that has come in for repair. The trim is fitted to the oven so has come out of the housing with it and there are even hand holds for carrying the oven to your car.

If you are in our repair area please follow this link for opening hours and bring your microwave into us and we’ll see what we can do.

How to replace the waveguide cover in your microwave oven

If your microwave oven is sparking or ‘arcing’ during cooking it may be that the waveguide cover is damaged. Usually the cover is made of a material called mica. Although strong and tough when new, over a period of time this cover absorbs moisture and food debris and becomes soft or breaks. If moisture or food embedded in it starts burning it will go from bad to worse quite quickly and if not replaced can cause irreparable damage to the microwave. It is advisable to replace the cover as soon as possible to prevent damage.

Note: In the interest of safety, please make sure your appliance is unplugged from the mains and that the area you are working in is safe.

Before you start you will need to know your model number in order that you order a replacement cover. 

You can then either order the correct shape cover to fit by make and model :click here to look for parts by make and model

or you can order a piece of generic mica material and make one to fit (supplied with easy instructions) : click here to order waveguide cover material

What’s my model number?

This can be found by opening the door and viewing the information sticker located on the left hand side of the control panel. Alternatively your model number may be located on the back of the oven.

Removal process

Changing the Waveguide cover is an easy process.

  • Firstly, start off by removing the screws that hold the cover on.

(Some models may have a plastic rivet holding it in place, simply prise the rivet out)

  • Then, once you have removed the screws/rivets you can bend the sides of the cover in and pull off the original cover.

(You may notice the cover is greasy, dirty and maybe slightly burnt. The reason Waveguide covers get like this is they absorb fat splashes and general grease in the microwave)

  • Thirdly, clean up the area behind the Waveguide cover using a good microwave cleaner to ensure the surface is near spotless

Fitting your new Waveguide cover

  • Line up your new cover in the Microwave, ensuring the screw/rivet holes line up.

(If using rivets, place the bottom half of the rivet in before the Waveguide cover)

  • Fit the screws back into the new cover and tighten

(Push the top half of the rivet back into the Waveguide cover holes)

Please try to keep the Waveguide cover clean by wiping gently occasionally with a damp cloth after use.

The correct Waveguide covers can be found on our website:

Really low power microwaves

We have been asked occasionally to supply microwave ovens that output even less than the usual 500 watt microwaves that we already sell.

Just to confirm, a microwave oven draws nearly twice the power in watts that it produces in microwave energy (also watts). Unfortunately our 500 watt ovens need a little more than a 1000 watt generator will cope with – they draw about 1150 watts.

We have just listed on our website by special order a microwave that draws less than 1000 watts so it will run on a 1000 watt generator.

It outputs 320 watts microwave energy but importantly draws only 810 watts.

We have only a few of these so don’t keep them in stock but can make them to order usually within a few days.

Please follow the links above for more information or click here to see the item in our catalogue.white-low-power-genix-microwave-1600px

Microwave Oven Power – Important Information for regular users

Following on from an earlier post, I wanted to let you know about the inherent problem with microwave power inconsistency.

Microwave ovens produce a set amount of power. This is normally indicated in the specifications such as ‘900 watts output’. However, as the components heat up through use the power level drops sometimes by only a small amount each time the oven is used.

The power drop off has always occurred but in earlier, older ovens the quality of the components used often made this drop off less noticeable. New ovens today tend to built of a lesser quality using more budget components so this effect is more noticeable and therefore more important. Independent tests carried out have found that in some instances microwaves may produce as much as 50% less power on just the second cook cycle.

It is extremely important if you use the microwave for regular repeated cook cycles ( such as heating more than 1 successive ready meal) that you check that the food is in fact piping hot not just that you have just done the same cook time as before and assuming that results will be the same. Because of this power drop off the cooking results are quite unlikely to be consistent.

24 volt truck microwave oven repairs

Just a reminder that our repair service for the 24 volt Samsung Roadmate microwave ovens is still very popular.

Although parts are no longer available for these ovens, we are able to repair the Inverter circuit board which seems to harbour most of the faults. Just send your oven to us and we will diagnose the fault and let you know the cost to repair and return the oven to you.

We now have on offer an alternative oven in the form of our very own Drivemate 24 volt microwave oven, which although slightly larger offers many more benefits than the Roadmate it will replace.
