Dometic RM 8xx1 fridge problem

[JaneyBMotorhomer In Hants]

Anyone got any ideas why our fridge is working fine for a while and then at random times beeps continually for a while with the plug and triangle icons flashing. This is while it is on electric plug in on site. Fridge and freezer seem perfectly cold. Ice cream is rock hard! Door is properly shut too and we have cleaned all the door seals. Doesn't do this when on gas operation.

Wasn't doing it either on the way to the site when it was on battery setting.

Any ideas would be most welcome!

Maybe there is an intermittent cutting out in the EHU supply you are plugged in to ?

Or intermittent low voltage??

typical of fluctuating low mains voltage

I think you are all probably right. We have never had a problem on this site before but we are on a different pitch to where we usually are. I know it is a particularly low power why site compared to most, it is only 10 amp. TV stops on though! Thanks to all.

a lot of TVs can accept a voltage between 110v and 220v AC and automatically reduces to 12v DC. So will have no issue coping with low volts within range

Man from the site has just been down. He says caravans have some sort of switch to cope with low voltage. You turn it down apparently. Don’t think a Motorhome has one??

We had that happen a few years ago on a campsite and decided it was a low voltage problem as well.

some older battery chargers had a switch to take account of input voltage. It has nothing to do with fridges

I am just glad that it isn’t a fault with the fridge!

Spoke too soon. Site maintenance man has been down and tested the 16amp supply and all is working fine. So it is most likely a fault with the fridge. Have to take it to a Dometic Approved place to be sorted.

If it is a low voltage problem it could be a time of day issue. The time others switch on electric heating for instance.

A telephone exchange in a small village in the cotswolds had a standby engine run most sunday lunchtimes. Turned out to be low voltage as electric cookers in the village were turned on, no gas in village. Supply authority eventually upgraded local transformer. This was over 20 years ago.

If it’s set on auto fuel selection then it should switch over to gas when the voltage drops, then back to mains electricity when it rises again.
You can easily see which fuel it’s using and keep an eye on the situation.

Used to get the same here at a friends house .All ok 9am then as day wore on the voltage dropped until you couldn't work . Usually had around 167v at that point which was solely due to people preparing lunch for the afternoon.

That is what you would expect but we are talking about Dometic and there stupid firmwear.
On the 8000 series when the voltage is too low the gas ignitor starts clicking but because there is mains voltage present the gas solenoid stays turned off. Sometimes the alarm goes off but not always.

Thats strage, as ours switched over to gas when we had low voltage.
Wonder if the new series 10 is any better

If voltage drop is the problem, a possible solution is a voltage stabiliser. This one will accept any voltage from 164V to 285V, and will output 230V (+/- 10%). This one is suitable for a fridge (460W, 2amps), but you can get any power up to a full 16 amp version.

I had the problem a couple of years ago and a few other Funsters have had it. They may have updated the firmware or it may only happen it the voltage is borderline.

I don’t think it is the voltage as it is the same on another pitch. It does not have an auto setting either. I googled it and apparently the wires around the light get damp. You need to remove the plastic cover, dry the wires and then Vaseline them to stop it happening again! This came from a Dometic engineer! Cannot see how to remove the plastic cover without potentially breaking it so will get Dometic to do it as it is still under warranty.

It just clips off, don't do it when the fridge is cold comes off easily when warm.

Typical of dodgy mains supply, may be low voltage.

If it is a low voltage supply issue, it will most likely affect the whole site, unless it was specifically down to an issue with the one supply point that you used, but you said that had been checked out. Don't panic until you try it out back at home or on another site.

Yes I thought that might be the case. We are back now and I will see what I can do with it tomorrow. Fridge will have been off 24 hours then. Then we will plug it into the electric at home and see how it goes but I seem to remember it doing the beeping before we went so I don't hold up much hope on that front. We will see.
