I am in Europe and the fridge is not working on gas but Ok on 12V and 220V. I replaced the battery as a first step and can see 1.5V at the input to the ignition box but still no spark. No idea how to measure the output. I could initially light the gas manually previously but now this won't even work (no gas at the burner). All other gas appliances work correctly. Got another couple of days before I can get back on 220V. Can anyone help?
 
Is the motorhome level or close to it?

Does the pilot light actually light, but then go out? If so it might be a thermocouple if it has one.

I've had a similar issue, everything seemed to work other than the fridge, turned out I needed to top up with gas for some reason.

Hopefully someone with your model fridge might be able to help
 
The motorhome is fairly level so no issue there. The ignitor will not work and therefore won't ignite gas. Trying to understand if gas is fed to the burner when the switch is depressed as I was able to manually light before but now there is no gas at the fridge.
 
Have you tried pressing the igniter button whilst another tries to light the gas at the burner side. Ie to check the solenoid valve is working.?

That's what we've been doing but to no avail. I need to understand what regulates the gas supply.

Are all the connections clean on the rear of fridge, sounds like bad earth.
Gas is usually through valve that needs correct volts through it to open.
Not sure what volt yours needs but you can test that if someone holds the know in and you ok using multimeter
 
Have you tried a sharp hard tap on the gas control valve?

Dont know what it looks like on your RM5310, but if you follow the gas supply back from the burner it should take you back to the gas control valve.

The valve can stick in the closed position and a sharp tap, metal on metal, may release it.

They look like this....

 
You could try cycling the main selector switch, the one where you choose 12, 240 or gas, backwards and forwards several times. These switches are a bit delicate and don't always make a good contact. The idea is to try and clean the contacts.
 
The gas supply valve is part of the Compact fitting that is at the top behind the controls and it could be worth checking the connections there , there also may be a filter in the gas inlet that could be blocked.
 
Thanks for all the replies. I did cycle the switch as I read that they could be a problem. I'm not sure about the gas valve but will check on my return (sightseeing).

I'll try to take the top front panel off if that's where you mean. Hopefully it's just a sticking valve.
 
Back at the van and still trying to settle my problem with the gas. Does anyone know how to remove the front control panel safely? Is it just held with clips?

Try a photo as that will jog someone’s memory as I have fiddled with quite a few fridges but don’t know what yours looks like

You need to keep a flame on the thermocouple tip in the burner area so it keeps the gas valve open. If it's not hot enough the valve will close.
Give the gasvalve a few taps with a pice of wood or similar just to see if its stuck.

Thanks. It looks like the gas valve is hidden on top behind the front panel. I'm not sure if this can be removed or if the whole fridge needs to be taken out to access it.
 
I recon you have to pull the knobs out and you will see screws inside the holes
 
Another way to check posibly before your pulling it apart if you can find a parts list diagram on the internet it might show the screws in there position in the diagram
 
If that is a current photo the left hand control is showing its on battery. It needs to be on the gas symbol in order to let the gas flow through.
You mat have changed it for the photo

Thanks but I can assure you it was on gas when we've tried. Just switched away until I figured out how the gas was controlled.

I'm also not sure taking the knobs off will help as they do not connect to the panel. I've tried carefully trying to prise it off but don't want to break it.

I did find an installation manual but it doesn't mention the front panel at all. Will need to try and find a parts catalogue and see if the front panel is listed.
 
The Internet suggests you have to put off the knobs first

Thanks for that. I'm not sure that is the case as they are just listed as parts that can be replaced and are separate to the panel. Looking at the diagram, it doesn't show how the panel is actually secured which is a pity. I'll just have to leave as is as I've run out of time. Back on the road tomorrow so will get the fridge to temperature at least whilst travelling. I'll then be on leccy for a night. Hopefully I'll figure it out otherwise will have to find an expert when I return. In the meantime, I'll try not to get food poisoning....😂

On the older fridges they were so fussy it was within 3.5’ or something stupid!
Switch the switch on the left to gas.
Then hold the adjustable temperature switch down whilst holding the igniter. Do not let go until the gas bar symbol on the right goes into the green then let go of the switch.

I think you have to open the door by over 90 degrees, lift the tip of the control panel, bending it inwards at the top to disengage the clips and allow it to be pulled forward and out. I don’t know if you can do that without removing the knobs first. If there are any plastic clips or fittings holding the control panel then they have probably become very brittle over time.
 
You can lead a horse to water but you can’t make it drink
I'm hoping that's a joke. I certainly appreciated the help everyone gave and will take all on board but as I said, I'm travelling tomorrow so not a lot I can do now. Unless, of course, you know definitely how to remove the cover.
 
Hi I’m sorry you have taken offence
All you have to do is pull a knob out and you will imeadiately see if that is the way to remove the frontal
I can absolutely appreciate your hesitance in case you break something or make another problem but you asked for advice and then said you don’t think it’s right after 2 people said they thought it was
I have taken probably 15 fridges apart over time and most of them with knobs on have screws behind that required the knobs to be removed first to find screws behind that released the frontal
If you do try it the knob may slide if easily or may not
Many knobs are friction held on with a flat spring tensioned tiny plate sometimes if exposed to moisture can rust a little and become tight
I do hope it goes well

Many thanks for that info. I'll give it a try when I get home as I won't have time now. 👍

Thanks for the better response. to clarify, I didn't completely discount what was said only that it didn't look to be the case as I have visibility of my fridge and tried removing the panel to see if the switches were holding it. As I've said previously, I will take everything on board when I have time to investigate further. I was hoping that someone with the same fridge may have been able to help. Perhaps they may yet.

I still don't think you initial comment was respectful or helpful but your follow up was so I will take that into consideration.
