Dometic RML 9435 burner issue

Some electrical / technical knowledge required here please. Last week, I decided to clean the fridge burner. So, got to the burner, took it out and emptied all the fine dust out of it, then thought I’d gently clean the top of the burner, and it started collapsing as I touched it. I suspect 5 years of rust and heat had weakened it. Anyway, I managed to effect a temp repair and ordered a new burner assembly, which came today. It seems easy to fit, apart from the igniter and thermocouple wires that plug into a module, on the back of the fridge that is impossible to get to without removing the fridge, which I don’t fancy doing. So, I have 3 choices. Leave as it is, but it will corrode more. Try to renew just the burner, but I think this is soldered in. Cut then rejoin the wires to the new module.
The wires appear to be single stranded steel. Is it safe to cut and rejoin these? Will it work?
 
hi. we had a big fridge in our old tag axel & it took 2 of us to pull out to replace the PCB unit . the fitter replaced the burner as well but ours was a thetford & it was just the burner that he changed the wires where before so didn't need to bother with those . me i would splice the wires if you can get to them is it this one then i would defiantly splice the wires but DONT use a soldering iron as on our first m/h i did & blew the fuse in the boiler so i ended up with 2 jobs🤬 cheyenne

thanks, it is that burner, but I bought mine for €82 ( we live in France. ). I decided not to cut the wires. I took the fridge halfway out. It’s simple, 4 screws and the gas connection, so, it’s all done now.
Pictures are original burner with temp Heinz baked beans lid repair ( it worked fine!) Damaged burner before temp repair, and new burner in place. Took about an hour from start to finish.

I find the hardest part is undoing the gland nut for the burner.

hi. north or south we lived between Toulouse & Auch near ( gimont ) glad you got sorted .cheyenne
 
Hi. Just wondering whether anyone has managed to source just the burner tube. Dometic do just the tube for some models but seem to want to take nearly £100 from us for what must be a £5 part
 
That was all I wanted really. The tube is held in by 2 steel tabs, easy to remove and refit, so it’s difficult to believe it can’t be sold seperately. But, the whole burner assembly comes with a new jet too, I paid €82 inc delivery. That’s around 70 GBp. Difficult to fit though.
 
This whole thread is why I touch f66k all technical on my van! No offence to anyone who knows what they are doing but Destroy It Yourself has never been my thing! People spend years learning to sort these things out and I for one am happy to let them do it! 😉😄

Yes, but if no one ever tried to fix anything themselves we wouldn't have the wonderful things those DIYers invented.
 
Annsman - I am happy to use tradespeople as well (I had the timing belt changed the other month) however anything relatively easy to fix then why not DIY. This thread is more about Dometic complicating something (manufacturing a burner unit that has to be changed as a whole) rather than keeping it simpler (manufacturing in such a way as to make just the burner tube replaceable. A bit like my new LED kitchen ceiling lights which are sealed units so the bulb isn’t replaceable (a DIY job everyone has done for years) and I have to get an electrician in to replace the whole unit when one of them blows.

And we call that progress 😩😩
 
You hear of people taking their vans in to the dealer for minor repairs all the time and they are usually waiting weeks for these to be sorted. I think you need a certain amount of knowledge and diy-ness to tackle things as they come up. Our van is coming up to 5 years old now. It’s been excellent, but there have been a few faults that I was able to fix myself and it’s never been back to the dealer for anything else . ( fridge burner, bathroom tap change, airbag ÉCU ( sent away for repair) bathroom door catch sticking and drain valve bracket coming loose. We haven’t missed a minute using the van and I’ve added to my fixing skills.
 
I think the word competent needs to be used with DIY, if you are useless then leave it alone but skills are built on top of smaller skills, you start by wiring a plug and go from there.
 
Replaced our burner recently (5yo van). We could clearly hear the flame fluttering from inside the van and, on investigation, the little tube was exactly like the photo above (post #3). Luckily, I was able to replace the assembly from outside by dropping the ventilation grills. A few scratches to the back of hands but job's a good 'un.

Regarding the general DIY thing, I do all the habitation repairs and improvements myself (retired engineer here) but I won't touch the vehicle. There are too many on-board computers requiring specialist diagnostic kit these days.
 
Retired from a job repairing electrical and mechanical stuff and I tackle everything I can. I’ve just finished renovating our old farmhouse in France. I’ll have a go at anything, but I know my limitations now and rule out complicated car mechanics and roof repairs.
Gone are the days of stripping engines and carburettors. You can’t even see the engines in modern vehicles now.

I once diagnosed that the habitation temperature sensor was faulty on my camper. I looked up the proper price, sat down and had a brandy or three. I pinged off the serrated small black plastic cover that is very common on all campers and lo and behold inside there was a standard thermocouple that you see in every domestic gas boiler. £3.50 from your friendly neighbourhood plumber's merchant. £65 from your not-friendly motorhome dealer spares department. Same thing. I recognised it as an item I had in my gas spares box, went to the garage and fished it out, fitted it and the boiler worked fine.
