Dometic fridge not lighting on gas (1 Viewer)

[DavidG58]

Morning all

I might actually have got very lucky and fixed this myself, but not confident

This is the back of our fridge, not that you can see much

I believe the first one shows the burner behind the plate (slightly bent due to me trying to see inside ) the second I think is the gas valve I have seen mentioned on other threads

Arrived on site yesterday, no hook up, after the initial delay when turning off the ignition we got an alarm from the fridge, flashing triangle and gas symbol

We could smell gas (slightly) so fairly happy gas getting to burner, could hear it clicking so happy it had power. Pressed triangle to try again, creates a few minutes delay before alarm comes back , tried this about 10 times then turned it off for the night

Read a few threads on here and got up more confident this morning, turned fridge on, went straight to alert, no delay no thinking about it just flashing and beeping

So took what was left of my refreshed confidence out into awning (yes that’s all working very well and safari room back up ) took grill off, gave it a hard stare, identified above components, turned fridge on, could smell a whiff of gas and hear / see the igniter sparking, (withdrew head ) alarm back on, turned fridge off

Gave what I think is the valve a very gentle tap, gave the burner area a couple of lungs fulls of my best morning breath , turned fridge back on , bingo it lit

I don’t have much confidence in it relighting when it should, but for now it will be on for a while cooling the fridge I would expect

Thinking I might just have got very lucky and blown something away from the critical burny bit

Come on you lot, this a motorhome support forum

I know it’s boring but anybody offer an opinion

 

[Figaro]

Congratulations on your apparent success
I think it was the hard stare and a good blow
May you beer and G&T's remain cold

David,

Could have been the gas jet blocked and you've cleared it. These are very sensitive to blockages.

Not confident it will relight after it cuts out next and not brave (or stupid) enough to turn it off to find out, I may still need more help

 

[paddymcc]

I agree it was probably the hard stare that did it. Might be worth turning it off and on when it's convenient for you rather than have to sort it again at 10pm. Mind you an awning helps.

I had similar last week.Did the same as you.light everytime .I wondered if it was a cobweb and blowing it cleared it .I am going to get a can of compressed air for future use.

 

[Lenny HB]

It worked after tapping the gas valve so probably a sticky valve it's quite a common fault.

Possibly a build up of soot shorting out the ingnition electrode, blowing may have cleared it. I used to do this on gas fires I have a small rubber tube for the purpose. Customers were happy the fire was working but less so with the £85 bill

 

[Jimbohorlicks]

best to buy an air cleaning aerosol ,the type used for computer keyboards and give your burner area a good blast with that.
If you have some rust or soot in the vent tube just driving over a few bumps can loosen it and cause it to drop onto the burner and stop it igniting

Our gas valve sticks very occasionally we use give it a tap with the shaft of a hammer whilst wife turns it on as soon as it starts clicking tap gently, use the van 6 moths of the year has happened twice since 2019 (new) not really a safety issue as if the valve doesn’t open no gas flows.

I would think it a blocked jet, you probably disturbed the the blockage.
Mines a different type but the jet is held in by the gas pipe.

 

[DavidG58]

Good news is it’s all working correctly again

So far

 

[PORKSTER]

Always clean my burner yearly.

I'm going to be an expert soon

[ivorantony]

I was taught, when in doubt give it a clout, It’s worked well for me

 

[Captain Yoghurtpot]

Always clean my burner yearly.

I'm going to be an expert soon

May I ask how you do that please.
Pics would be appreciated if available.
Thank you

 

[Reallyretired]

Probably the inflammability of the morning breath did it.

Any euphoria I had when my actions solved the problem were lost in my concern that I hadn’t really got a clue what I did to fix it

It must have been a bit of something in the way, but as I couldn’t even see the burners it was pure luck, reading threads where people change their burners I have no idea how I would start that

I presume the metal ‘cage’ around the burner can be removed, all I could do was bend it a bit to try and have a look

Still working though

Always clean my burner yearly.

I'm going to be an expert soon

 

[PORKSTER]

I really am no expert but that metal bit you bent normaly held in with one screw. Then burners exposed. Debris normally blocks gas. Hence I give mine a good blow out. Very fiddly to clean flue on mine. But I assume that should be done yearly.

 

[namwaldog]

May I ask how you do that please.

I put a post on here a couple of years ago showing how I did mine.....

RMD8505 F/F not cooling on gas - How I fixed it. (inc. pictures)

We have just returned from a week up in Scotland. Not been on EHU at all and F/F was fine up until day 6 when we noticed that the fridge wasn't cool and freezer was defrosting. There were no warnings lights showing and the flue was just warm. When we got home, hooked up ehu, turned off gas...

Debris from dirty flue can cause problems at the burner,, sticky valve also often the problem usually solved with a sharp tap with hammer or spanner.

Could you just pop over to the side of the Seine and do the same to ours. I’m just going to post about it.

For the first time since swopping the MH we are parked up in France without EHU. The fridge will not light on gas. …
The boiler and hob/cooker light ok.
I spoke to Camper U.K. who explained that it will need probably 15 minutes to settle after turning ignition off. That hasn’t worked. Done a full turn off of everything, still nothing. Triangle and blue flashing gas light showing on 3 way panel. I don’t know if it matters but we have no clicking sound.
So as well as no telly (previous post), we have no fridge, and the door step is going in and out on its own….again, and it’s sleeting.

I don’t know if it matters but we have no clicking sound.

I am sure that is the key, but no idea what the solution is

We could smell a bit of gas so knew our valve was working , don’t think any amount of puff will fix this

When all else fails I do resort to multiple turn off and back on again attempts , good luck
