Problem microwave in 2019 Bourton

Has anybody got any thoughts as to what is wrong with our Russel Hobbs Microwave in our 2019 Bourton ,it will work perfectly for 6 to 7 minutes then cuts out and the separate switch you turn the microwave on with also cuts off and the red light goes out,  10 minutes later its comes back on and works perfectly for a short time then cuts out again.We have spoken to a chap at Willersley but he didn't really seem to know, we have spoken to our dealer and are getting a new microwave under warranty but are not 100% sure it will cure the problem, any ideas ?

Our Daewoo does the same (and my Sussex is a 2010). The Daewoo problem was common, hadn't  heard of it on the Russell Hobbs. Ours ,I believe is due to overheating because it is mounted in an enclosed space with little air surrounding it and no vent to the outside. I'm not familiar with how it is fitted in a Bourton but the fault sounds the same.

Yes had exactly the same with my daewoo microwave....overheating.
I solved it by fitting two fans to take out the heat that Paul has suggested trips it out....the bourton I assume suffered the same issue.

I put a couple of small circular vent grills in around the microwave to allow more air but hasn't worked. I'd be interested in how you fitted your fans, where you took power from and any switch you put in.

I fitted two fans, this is a spare bathroom fan I had...the other is a 12 volt computer fan...fitted after this photo was taken..

Re outside vents: Our Broadway has an outside vent and an inside vent to the room. Whenever there is any wind we get the draught straight into the van round the edges of the microwave. Lack of ventilation there is not ! It looks like the same vent as in Libraryman's Corinium above.

Despite this excess of ventilation our Daewoo gave up about 3 years ago in Spain and we replaced it with a much more basic German OK brand one. The mechanics of the Daewoo worked perfectly -ie lights on and platform spinning-but no cooking so we think it was either the magnetron or the high voltage fuse, neither of which we could safely sort ourselves and no firm would look at it. 

Fingers crossed the OK one is still OK.

Hi. I know it’s nearly 2 years since this topic was raised, and I was wondering if you solved your microwave problem.
I have a 2019 Broadway, which I purchased in late 2021, with a Russell Hobbs microwave. 
The problem you described is exactly the same as we are experiencing, and wondered how you resolved the problem.

Thanking you in advance

I purchased a new microwave from Asda (cheapest I could find).  It's a little smaller all round so an air gap for escaping heat,no more problems.

Thank you Paulmold.

I will try that idea.

Again. Thanks.

Confirmed, my 2018 microwave also overheats and shuts down 

So did our 2017. I think it was a Daewoo. Interestingly, in our 2020 Warwick, a different M/wave was fitted (Russell Hobbs?). It was a little bit smaller and the trim around the housing wasn’t fitted. It looked pug ugly but had much more room for air circulation around it.

I’ve also had the same issue with caravan m/waves overheating in the past. There simply isn’t enough ventilation.

Thank you all for your comments.

I replaced the Daewoo in our Broadway with the only cheap one that fitted which turned out to be a Russell Hobbs. Not a particularly east job. AS secure the unit by screws through the wooden shelf straight into the chassis of the microwave in a fairly random location! My electric drill was just small enough to drill up through the existing shelf holes into the base of the new appliance.

Hi BornAgain.

Thank you for your post. What is the model number of your new machine? and has it cured the problem.

Thanks.

Bill

When I replaced mine I made a template of the fixing holes to ensure they didn't hit anything inside the microwave, drilled a tiny piot hole in base plate and used a cocktail stick to check the clearance before a screw would hit anything.

Thank you Paulmold.

Advice taken on board. 
Still trying to find a microwave smaller than the existing.

Sorry, I don’t recall as we traded the van in for a Bourton but I bought it from John Lewis. Seemed to work for the  short period I used it and AS switched to Russell Hobbs anyway.

No microwave in our van, but manufactures make models that are designed to be fitted flush in domestic kitchens, why not fit them to motorhomes? I fitted one in our kitchen in a fully enclosed opening some years ago. Small capacity, it only protrudes about 20mm from the surface fitting, and is vented through built-in slots top and bottom. Much neater than having a gap all around.

We used ours to store bread in so never had an overheating problem, had we kept the van it's have been removed and replaced with a much more useful cupboard.
That would have the added benefit of working off grid!

Thank you all for your replies.

Hi Bill and other contributors.
I have experienced a similar fault on our 2019 Bourton.
In our case it was the main supply line to the Kitchen area from the main harness behind the Sergeant fuse panel and Mini Circuit Breakers. 
There are a couple of large white “plug and click” connectors on the 240 volt supply white 3-core cables and there are two click lock tabs on each cable. 

On our MH two of these were only clicked in place only at one side of the receiver plug allowing the cable plug to move, so when the cable heated as it passed power, the plug could move and lose the electrical connection
It was a simple job to carefully lift the cover over the wiring area (under the off side bench seat) by removing a couple of wood screws  and hingeing up the cover from the front, then after turning off the power, pushing in the plugs on the 3-core white cables which clicked fully home into their sockets. The microwave immediately sprang to life again and hasn’t given any problem again in the past 4 months.
Hope this helps,
Boggie.

Thanks Boggie.

I will have a look.
