Fridge keeps turning off - no answers in previous threads

Our fridge keeps turning off! I've searched previous threads which recommend going into diagnostic menu and clearing errors but ours shows as no errors. So there's nothing to clear.

We're on leisure battery which states we have 80% left and 11.4v (don't know how we change voltage if that's an issue?).

Help - fridge is full of food and 3 more days camping to go!!!
 
The battery is flat. Ignore the 80% and focus on the volts. I believe the fridge turns off at 11.5

Oh. That's an arse. Only been camping a day so I guess that means we need a new leisure battery as it's not keeping its charge.

I was in that same position 3 weeks ago which is why I knew the answer.
 
Yes, above answers are in line with what I was once told. At 11.5v the fridge and the auxillary heater are turned off automatically. If you try and start them at 12v you might already run into problems as they have a peak usage when starting up.

I try to keep 12v in my mind as the lowest I let my batteries get to.

Don't know why or how my avatar says I'm looking as didn't join the forum until after I'd bought one I don't think and don't think I ever set it as anything and no idea how to change it! I can't see anything that says still looking when I click on the avatar...

OK, now we know you have an Ocean that has 2 Leisure Batteries, you should check the voltage of both batteries, after disconnecting the black -tve lead on the rear battery. You should also check that the Cube fuse on the red +tve pole of the rear battery is intact.
You may be running on just 1 leisure battery.

Thank you. Will get the manual out and investigate.
 
For completeness. Your fridge has a voltage monitor that turns it off when the supply from your leisure battery drops below a certain level (it varies but around 11.5v).
This is to protect the battery. If the battery is over discharged then it will be damaged.
Depending on your current set up, it migh be worth considering buying lithium batteries (or even just 1) but that might incur significant cost in replacing components (hence “depending on your set up). Lithium allows you to use almost all the energy in it (lead acid only 50%), have a longer life, charge faster and are lighter. An AGM might be a reasonable compromise .

Meant to say. The fridge volt monitor, like your battery monitor, uses bolts as a proxy for the amount of energy in the battery. Because volts don’t drop in the same way on a lithium battery as they discharge, a lithium battery would need a new shunt and monitor .

The fridge also turns off intermittently even when batteries are well above 11.5V. It happened to me the first time I was on EHU hookup.

I don’t have hook up. But, when you say “turn off” do you mean completely, or is it just the fridge maintaining temperature?

The fridge turns off (light on display disappears).
Resurrecting this thread as I now have the same issue. Fridge has started turning itself off at 12.5V. I have one of Rogers 100w solar panels which kept the fridge running 24/7 last summer even in +30°c

No error codes showing - batteries are nearly 6 years old and the van is used almost daily. Anyone have any thoughts before I let Breeze loose on it

If this is the voltage reading on the panel, I would measure the voltage directly at the Fridge connections and that will help to understand if this is the Fridge controller switching off due to low voltage or perhaps another issue.

If your habitation batteries are 6 years old they are probably on their way out.

Does this happen when on EHU?
What voltage is displayed on the Control Panel when the Fridge compressor starts up?
 
To see the true state of the leisure batteries you should not be on EHU and Solar disconnected.
If your battery is showing 12.5v whilst solar and or EHU is being used then afraid your leisure battery is knackered.

I’ve put it on EHU and fridge runs continuously. I’ll monitor the voltage

Thanks. The batteries do get to a full charge (12.9v) when driving, using the solar and on EHU. So I’m mystified as to why fridge keeps switching off. The batteries have never been below 50% in the two years I’ve owned the van, 12.1 is the lowest voltage I’ve seen.

If you have put it on EHU then your fridge will work as your charger is putting charge into the battery but you are proving nothing.
You need to see if your battery is actually holding a charge.
Ps. If you start to smell a fishy smell then disconnect EHU quickly as it's you battery boiling.
 
Thanks everyone for your suggestions/advice, I will continue to monitor and report back.
