How can I repair the turntable floor in a microwave oven?
I have a Sanyo domestic microwave oven approximately 8 years old that
still functions all right. The problem is that the floor of the oven on which the glass turntable rotates on its spindle is rusted through in one or two places. The turntable still rotates okay, but if the floor is left to rust through further, sooner or later the little carrier wheels that support the turntable will get trapped and the turntable will lock up or something. How could I repair the base of the oven? I have thought of Kurust first, followed by a layer of epoxy resin soaked fibreglass from Halfords. Any other ideas? It seems daft to buy a new microwave if the actual heating feature works fine. Similar oven he http://img.dooyoo.co.uk/GB_EN/175/ho...yo-ems1067.jpg MM |

Would you cook in a rusty saucepan? 2. If the holes are of any size then the microwave cavity will no longer be intact which is not a good thing. 3. They're cheap, one like the picture you linked to will cost you all of £25 in Asda or somewhere similar. If you value your time at all then it's cost effective to replace. You'll spend half the replacement cost on 'stuff' and then time as well and still be left with a crappy old microwave anyway. If it makes you feel bad then make sure you recycle it nicely. Design life is ~5 years so even if you do fix it the microwave generator will probably pack up soon anyway! Fash |

Your problem is any repair is going to have to be 'invisible' to the microwaves, otherwise you will cook your repair along with your ready meals, not only that but if the microwaves get deflected and your door seal is not 100 percent you might also cook yourself! Quite frankly, whilst I know that this is a DIY group, with new microwaves being circa 50 UKP in the supermarkets.... |

MM formulated the question :

It seems daft to buy a new microwave if the actual heating feature works fine. Any small metal particals which become detached from the oven case will causing arcing and burning - which is why rust in an oven gets rapidly worse. Any repair you needs to be well bonded to the rest of the case liner, if it is at all conductive to microwaves and any holes in the lining can permit microwaves to escape and put you at risk. So generally the only sensible economic option is to buy a new oven and if you want longevity, get a stainless lined one. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

I had exactly the same thing happen on my LG. In the early days a bit of foil causes some arcing which took the paint off under the turntable and I failed to touch it up. Of course moisture collects there, so the bare spot is repeatedly dosed with boiling water so rusts all the quicker. It's a good reason to buy one with a SS interior, though they tend to be more expensive. -- Tony Bryer SDA UK 'Software to build on' http://www.sda.co.uk |

Sorry, but that's an immediate PAT test failure because of microwave leakage. You need to render it unusable (cut the mains cord off right up against where it enters the case) and dispose of it. Repairing it safely and correctly would be much more expensive than a replacement. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Needless to say we went for a brand new one. I know. And the council keeps telling us to recycle. How much better to design things to be repairable, as once was the norm. Imagine just buying ONE washing machine, ONE toaster and never having to buy another. I mean, what washing machine is dumped because the drum is worn out? Same with the outer casing. The modern way is designed only to suit fat capitalists. Think of the work there'd be for thouands of trained workers to repair appliances. Much more rewarding, mentally and physically, than a call centre. I imagine a world in which the local Replacement Officer calls unannounced to remove your appliances that are older than, say, six months. "Sorry, Mrs Jones, but you know the law. New one every quarter, otherwise it's a £5,000 fine and two years in the slammer." Well, this IS Britain, after all. A place where the state can get away with anything. MM |

Now what about the mesh in the door? As anyone who has ever tried to make an RF-tight screening box will know, the problem of totally confining the RF energy bouncing around the innards of such an enclosure so as to eliminate unwanted interference to other kit or other modules within the apparatus is not quite so simple to solve as it may appear to the uninitiated (I had quite a laugh at the EMC 'measures' being introduced in the construction of personal desktop computer cases nearly two decades ago). Whilst a screening mesh with a hole (or a few holes) less than a wavelength in diameter makes a reasonably effective screen, it's not perfect, merely 'perfect enough as makes no difference' in practice. Such a screen won't totally stop such radiation passing through, it merely attenuates it to a much lower level (maybe 40 to 60db per sub- wavelength hole?). This is usually more than enough when the waves only get one chance to pass through the screening mesh. However, in the case of the cooking cavity, they'll get hundreds, if not thousands of attempts at leaking out as they bounce around the low loss cavity. The food will absorb most of this energy... eventually but there will be eigentone pathways not obstructed by the food where the levels of radiation will be magnified hundreds to thousands of times the average level in the cavity. Quarter wavelength diameter holes in the viewing screen mesh won't offer sufficient attenuation, halving the diameter of these holes will require a quadrupling of said holes which counters the improvement in screening to some extent, hence the *very* small size compared to the wavelength involved to sufficiently attenuate radiation leakage to below a level deemed to be acceptably safe. The smaller the holes, the better and the most likely reason for their extremely small size is probably more to do with the lowest size possible without offering too much obstruction to viewing the contents rather than a maximum allowable size to contain the microwave leakage to an acceptable minimum. -- Johnny B Good |

How can I repair the turntable floor in a microwave oven?
Ahole, how did that happen anyway?
Basically, you need to use screws and a bit of metal. The piece has got to be seen as part of the whole. Most ovens interior size is cavity which loads the Magnetron to some extent, but there are always areas that are more concentrated where standing waves and cancellations occur, hence the need for a turntable to move the food around through these variable areas. actually the leakage from a small hole is not as great as you might think. Often it depends on where the whole is and the design of the cavity. A small patch should be tolerated as long as it is seen as part of the cavity wall.

How can I repair the turntable floor in a microwave oven?
The issue of holes in Microwaves does beg the question how did the hole get
there in the first place of course. I stand by my method. I assume one can still buy those microwave leak detectors. The most likely place for the microwaves to leak is at the door bottom which tends to rust away. Short term, ie ten seconds or less exposure is not going to do you much harm as you measure the leakage. Remember its a party trick in radar labs to heat up your sandwhiches using the open end of a waveguide when it is connected to a magnetron. :-) Brian -- ----- - This newsgroup posting comes to you directly from...

I thought it was complete ******** too; it treats microwaves as if they're tennis balls, but I'm no microwave expert. If it's not ********, and if microwaves can't leak out of a hole smaller than 12 cm. why all the fuss in the past about microwaves leaking around ill-fitting doors, and why the need for a fine mesh across the window in the door? If the article is OK, you barely need to shut the door, let alone worry about leaks around the edge, and wide-mesh netting would do in the window allowing a much better view of the contents. What am I not understanding? This issue is nothing specifically to do with microwaves. It relates to *all* sorts of waves and their behaviour. Look up diffraction. I'd do it meself, but SWMBO has just announced that the scoff is ready. The issue us not diffraction, but reflection. You don't need a perfect surface to reflect. Its the same principle as using a yagi array or similar. The presence of the metal bits affects propagation around a far greater volume than they physically occupy, because a field is induced in the nearby areas. -- "When one man dies it's a tragedy.

Diffraction is not really relevant. -- €œIt is hard to imagine a more stupid decision or more dangerous way of making decisions than by putting those decisions in the hands of people who pay no price for being wrong.€ Thomas Sowell |

I'm saying that considerable energy can diffract through that (apparently), even if the mesh size is less than the wavelength. If considerable energy can diffract or otherwise pass through wide mesh netting, and I don't doubt it for a minute, how can a bloody great hole 12cm across not be a major hazard, as the article linked to at the top of this thread said wasn't? (hope I've not got double negatives there, but YSWIM!) well 2GHZ is around 3.75cm for a quarter wave.. so its of the order of a wavelength anyway. I am fairly sure that diffraction is a bit of a red herring though. Its one of those lectures I probably didnt pay much attention to, but I think its a matter of reflection.
