Daewoo Microwave goes POP

Interesting to see the photos of the empty bay. Thanks Mr Chippy.
I have never removed mine and I have been wondering what is in there.
I expected to see a 230V 3 ping socket that the microwave plugs into.

How is the microwave powered?

Hi Mr Sleepy   It's Windy to you, can't abide formality. LOL

If you look at the pic of the empty bay in the top right you can just see the black cable feed from the microwave that I had to splice into the white (A/S supplied) feed.  There is loads of slack cable, enough to remove and lower the micro onto the top below. It's then just a case of unclipping the three pin bayonet connector (A/S supplied)
Notice the shelf front edging, this has been falling off a small piece at a time. Will replace with a nice bit of lacquered timber slightly taller so as to hide the new Alu. base plate

I wonder if members could check there microwaves to see if they have movement. Check on the R/H/Side of the micro as this is where the weight is and see if the micro can bee lifted until the micro hits the housing above. If it does then this might indicate that the screws have broken the base as in my photos.   
I have emailed Autosleeper to advise about my damage and am awaiting a reply.

Cheers Windy

Good day all. I had the same problems, the oven just stopped working so I got a replacement. But now the right hand fixing screw keeps working loose after a few miles on the road. So far I have replaced the screws, drilled out the hole and fitted a wall plug and glued the wall plug but it still works it's way out/down. As a back-up I have fitted a thin timber strip along the front so it cannot actually fall out. There is obviously a lot of movement of the M/W when in transit. Expecting 2 thin screws into thin steel to hold that weight is expecting too much,IMHO. Windy's silicone might just be the better method. All it has to do is keep the thing from moving about. Thanks.

There is space above and below it, a substantial vent on the side cabinet wall ( which, unlike many, we do not have coats hanging over), and a vent outside, above the external fridge vents. More in fact than many domestic microwaves in cabinets.

Hi Quilter

Recently back from holiday when our microwave gave up the ghost twice when heating up frozen baked potatoes. Each time it came back to life after a wait of 10 minutes or so, which must suggest the overheat trip popped and re-set itself after cooling down.

I don't know for sure but I think your van is identical to ours in the way the microwave is installed, so it may be worth having a re-think.

I'm planning to fit a couple of computer fans as suggested by Chalky earlier in the thread.

Cheap and easy enough, and it might make all the difference. Moving the air round in the enclosure can't make it worse anyway!

I’ll keep an eye on it Dave but I don’t think it has ever been run for longer than 5 minutes at a stretch. I put most veg into steamer bags which only take a couple of minutes, do baked potatoes in the Remoska and cook porridge in it in winter.

We replaced the Daewoo with a German one after the Daewoo fuse/ magnetron went. This  has mechanical controls , no bells and whistles, seems robust and is firmly anchored in the cupboard.

Incidentally, we were at a caravan accessory shop a couple of weeks back and they had a glass plate for a Bailey ( caravan) microwave for the eye- watering sum of £35 !

Ours hadn't before this, but friends we were with introduced us to the frozen baked potatoes.

We  normally avoid "convenience" or processed food where possible, but these seemed OK, with no nasty additives or permitted flavourings etc.

In fact they are very good, but they needed 5 minutes each (and it advised doing them separately) and the microwave wasn't up to doing both of them, one after another.

No great catastrophe, but irritating when the microwave is usually so quick and convenient.

My way of doing it by using bobbins, it's been perfect since.

Peter, 
Is that bobbin vibration mounts, if they are thats good thinking. Bolted inside the base and then under the shelf??

Cheers Windy

And those bobbins give an extra 5mm ventilation under the microwave - I like it!  Wher did you source them?

I used male / female with male inside microwave with large washer and lock washer and hex bolts from underneath shelf with large washers and lock washer underneath hex bolts.

Peter,

The bobbin way is a much better way (me thinks) than my complicated effort. Although mine should work, (to much effort) and I have already invalidated the 3 year warranty that came with it.  
IF A/S get back to me do you mind me mentioning your method of fixing, Credits going to you of course.

Cheers Windy

The damage to the shelf as shown is remarkable. I agree that more reliable mechanical fixing is required. The bouncing up and down on that small foot has hammered an impressive hole and will almost certainly explain your oven failure which is likely to be the heater filament in the magnetron failing. The ZZZZpop sounds like this sort of failure. You sometimes get a similar sound when old tungsten light bulbs fail. Here are my thoughts...

Microwave ovens are designed to sit on a counter-top in a kitchen, not in a vehicle that subjects it to jolts, shocks and vibration while being driven. The magnetron inside (the part that generates the microwave energy} is very susceptible to damage from vibration and mechanical shock, so I think the anti-vibration mounts will do no harm. Wether or not they will protect from pot holes is another matter, but they would be no worse than how it is done now in that respect.

Most of the damaging vibration will be isolated by your vehicle suspension, of course , but a little extra peace of mind is always worth pursuing.

On a safety note, microwave ovens are potentially very dangerous things. The Magnetron has a high voltage connection inside of around 5,000volts and will kill if you get near or come into contact with it. The energy generated actually travels at the speed of light and some foolhardy DIY-ers have been seriously injured by experimenting with microwave oven parts. The Magnetron has high temperature ceramic insulators that contain Boron which is very toxic and will harm you. I used to work in this field and have stripped magnetrons under controlled conditions to made visual aids for training purposes, but I would never advise a DIY strip-down to see how it is made.

Let me help manage expectations. The more arduous conditions in a vehicle will very likely reduce the working life of your microwave oven, so early failures are to be expected. Don't expect to compare the life time reliability with your fixed kitchen microwave and be glad they are not expensive to replace. It is clear that most motorhome / caravan mounted microwave ovens will outlast the warranty period (or the likes of Auto-Sleepers would not fit them), which is normally the same as for any domestic microwave oven (12 months). As they were never designed for mobile use, it would not be reasonable to expect the motorhome or caravan manufacturer to carry the burden of extending the original warranty to match the other appliances that have been designed for mobile use, like fridges etc.

Of course, I now expect someone to tell us that their microwave oven has done 120,000 miles in their motorhome and has lasted 10+ years!. There are always exceptions. 

Hope this helps.

Dennis

Dam I love the sense of humour you guys show here really cheers me up    kkkkkkkk

Hi Windy,

Mark has already seen it when it was in for it's hab check and commented it was a proper job but did not ask about any details of it. If you want to mention it that's fine.

The one's I used are as follows:

2010MF12-60

20

10

M6

12

17.5

1.2

£1.79

If you go down this route I have spare allen screws, nuts and washers that you will need, so let me know if needed.

Thanks Peter for the offer of the spare allen screws etc.  but the new micro is all fitted with the new base plate. Will hopefully work for a while until it shakes it's self apart again.  I will hopefully remember your method of fixing for the future but theres no guarantee as we get older
Cheers Windy
