Microwave leakage testers

A customer recently brought his microwave into our shop reporting that it was leaking microwaves. I had asked him on the phone how he knew this and he said the leakage meter that he had bought online was reporting leakage. He brought that tester with him and sure enough, in our workshop the meter reported leakage. However, we then immediately tested for leakage with our professional test meter and found no leakage at all. Upon close inspection we found that at very best the cheap meter just monitored the prescence of electrical noise, the result of any electrical motor operating will generate. It had nothing to do with measuring the prescence of microwaves.

We looked on ebay and found his meter and another both available for less than £10. Bought them both and of course in the workshop report leakage. In fact we found anything that had a transformer would show as a reading.
In our opinion these testers are completely rubbish and certainly not to be used as microwave testers. Our advice would be that if you have any concerns about microwave leakage to contact us (or your local microwave engineer) and we can test your microwave for leakage using a professional, calibrated test meter. 
Incidentally, we always test a microwave for leakage after any repair as part of our workshop procedure and only very rarely find any leakage so it isnt something that should concern domestic customers. Commercial customers will have microwaves tested regularly anyway as part of their employees Heath and Safety commitment.

Samsung 24 volt microwave microwave oven bulb

We have been waiting for some time for Samsung to supply bulbs for the Roadmate 24 volt microwave. Having looked at the actual bulb assembly we found that the fitting in these ovens is the same as vehicle side lights and indicator bulbs. This means that when the bulb fails you dont need to change the whole fitting, you can change just the bulb. The bulb fitted is a fairly standard bayonet 12 volt, 21 watt, single filament bulb !

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:

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.
