Dometic Fridge Problems (1 Viewer)

[irnbru]

Anyone knowledgeable here, ...thats actually a silly Q as i know lots of you are Theres a lollipop on offer Might be a melted ice cream one though HaHa.

So the fridge seems to keep turning itself down. Alans cleaned the burner and the jet and it appeared to be good for a few days but now back to being a crap temperature. Burner is still lit and main gas regulator been changed too., how can we determine if its the thermostat?

Been trying to find a repair specialist but seem to be having a run around.

Ok I take it back what I said about you lot being knowledgeable. No replies..35 views so ..You lot ..Must be as thick as S**t . Will this now get a response

 

[andy63]

Well i know im thick... thats why i didnt reply..
But i got the impression your fridge worked ok on 240v ..so assumed that you would know if the thermostat was functioning correctly ..
Ill claim my lolly next time i see you.

Perhaps those that have skill to help get somewhat dissalusioned by having to keep asking basic questions, like which model etc. My fridge ain't working is not too constructive. But good luck.

... they've all been waiting for my NEC Tickets draw to be announced so you should get hundreds of responses now!

 

[Minxy]

Are your other gas appliances working okay?
How cold it is where you are?

 

[sallylillian]

And neither is your post

Sorry but seriously troubleshooting is difficult as it is but blindfold and both hands tied behind you back. However I will accept my rebuke with good grace

Its not cold..23c roundabout, yep everything else on gas is working fine.... Fridge is on 12v and elec, but the burner isn't getting hot enough on gas. If its not fixed 2mor we will be having a free BBQ

Dirty jet on the burner, keeps getting clagged up?

Ta but we tried that. Cleaned both the jet and the burner.

... so what are you typing with?

 

[Minxy]

Have you checked the 'flue' bit above the burner just in case it's a bit blocked up and not allowing it to 'vent' correctly? A daft question maybe but you don't turn on and off your 'stop' taps do you? I'm just wondering if the one for the fridge hasn't fully opened ...

 

[dabhand]

The burner isn’t getting hot enough on gas? I’m not understanding this, it’s either on or off isn’t it? Or...... am I missing something, if it’s not making fridge cold is it the thermocouple?

Its a long time since I looked at the back of a gas fridge so can't be sure but doesn't it have a thermo-coupler flame detector thingy to ensure the burner is lit before it allows the fridge to go into working mode ... I'm just wondering if the thermo-whatsit is bust, or not sufficiently lined up with the burner flame, to get hot enough to 'release' the gas.

Great minds think alike ... you snuck in whilst I was typing!

Sandra, Seems like the problem we had recently with our fridge. It wasn't the jet but a build up of crud in the small flue directly above the jet which kept dropping down and reduced the jet to a point where the fridge did not cool properly.
Was easily cleaned by both tapping on the flue and we then used compressed air to blow it out clean. Obviously don't know if our solution is of any use to you
Hope your both enjoying your holiday

Good thoughts guys n gals but the flue is spotless, the gas is on but the flame is low. Alan did wonder about the burner not being aligned correctly,... all looks well .. the fault seems to be intermittent, nothing seems to have moved. Its a puzzle for sure.

 

[Puddleduck]

I'm no expert but just thinking things through as best I can.

If it is working on electric then unlikely to be the thermostat unless there are separate thermostats for gas and electric.

If the flue is clean then that is not the solution.

When the burner was cleaned was it knocked out of place a little or put back a little out of place?

Something restricting the flow of gas?

Or @Minxy Girl 's suggestion of the thermocouple being out of place or banjaxed.

I am sure you have already checked that the external vents are clear.

 

[SomeoneElse]

There is likely to be crap in the gas pipe. Disconnect the burner and start the ignition procedure withOUT the spark. That will clear out the pipe, blasted the gas into a damp cloth to catch the muck. Then make sure the jet is completely clear.

If it has a small flame---- that is the cause of bad operation IMHO-------- as previous poster said remove jet assy and turn on to check gas flow TO the jet, there will be a very good flow of gas----- dont let that gas see a spark or you could have other problems!!!!!!--------have a really good look at the jet, soak it in solvent and blow through--- replace jet-------if is a newer jet which is like a very thin washer, be sure it is seated correctly, -------------i dont remember if you had cleaned the burner, a small soft wire brush is good for that!! -----if the flame is still small put the kettle on and sit and enjoy a peaceful beverage and go back to the beginning and start again!!!!!!!

Hi sandra and alan...
Ive done a little googling and my understanding of a modern thermostat is this...
Posting here so others who know better can add their thoughts..

The fridge thermostat is either on or off..
The calibration on the dial sets the temperature you want and whatever the power source it will run until that temp is acheived then switvh off...
And back on when the temp rises...
In other words the size of the gas flame shouldnt vary as you move the control on the thermostat... it should be a full flame as long as the gas control is on..
The sensor in the fridge works on a gas pressure... which is dependant on the temp in the fridge...and switches the heating source on or off...
Hope ive made that clear enough..
And i did read that on some units the temp range of the thermostat can be altered by a small screw in the unit...
Ie setting No 4 on the thermostat may be set to give 0 degrees in the fridge but that could be altered to say 2 degrees by adjustment...
Anyways hope you get it sorted... i dont want my lolly melted when i get it
Andy..

 

[Puddleduck]

And just something else that may (or probably won't) help but you might need to check.

On our Chausson we would think the gas had been turn fully on or fully off but wasn't because the plastic over tap had distorted inside and would only turn the brass nut so far. A small spanner was needed to fully open or close the gas supply.

Mine done the same thing on franky got to the stage I was cleaning the flu pipe twice a week. Got a new burner fitted and it was better than ever.
They don't last forever even when they still look ok so it may just need a new burner and jet.

 

[scotjimland]

fit a new jet

 

[irnbru]

So today the fridge got fixed...We hope. Engineer explained that although the burner seemed clean, due to corrosion the hole was smaller than it should've been for the mixing of gas etc so he replaced the burner. Lets hope thats the end to the problem. Thanks for all your replies.

Lets hope thats the end to the problem.

Hope so

hi peeps.. just a quick update, fridge conked out again a few days ago same issue, burner not getting hot enough. Sandra said its cos I moved the temp dial/knob on the front I,m not sure about that. but not too far from Murcia (where the engineer resides) we decide to go back and let him have another go. after having a look he said turn it down its all too hot ( it was set about 3/4) so he turns it down to about 1/3, then went to "help" another customer, came back 15 mins later took off the outside grill and declared the burner not hot enough. he then removes burner and jet saying its the wrong jet.. ok said I but its the same jet I've had for about 4 years and it was working fine 5 days ago after he fixed it.... any who he went off to get another jet..meanwhile I got an eye glass to look at the jet,. all clean with number 45 stamped on the side.he returns with new jet and declares I have the wrong jet fitted and it should be a number 65 that he was removing from a sealed bag. is that a bigger jet then, I asked, no its smaller was the reply.... so its fitted and fridge appears to be ok again. Sandra seems confident all is well, I hope so, but don't share the same optimism
here's hoping lol Alan

 

[Gellyneck]

OK, Sandra says wasn't working because hole was too small due to corrosion and the guy fits a smaller jet? Mmmmmmmh
And I wonder why you're sceptical, Alan?
