According to the manual 5A is correct, I’m surprised a 10A fuse is standard, maybe because it’s the same fuse for the bigger models.
There is a fast cooling mode according to the manual.
The Red LED gives a series of flashes to indicate faults, see page 29 of the manual. It’s online if you don’t have a paper copy.

What was the ambient temperature when you started and was the internals of the fridge at ambient?
Also is there good air circulation over the radiator at the back of the fridge?
You say a it's a CRX model so it has a radiator like that in a big computer or server with a fan attached to the rad?
All of that influences how long the compressor runs.
My CRX65 is currently off and empty with the door in vent mode.
I've switched it on (at 19:45) and closed the door, the ambient in the camper is 25 degrees. Discharge was a little under 5A battery volts 12.5V at battery. There is a 100W solar panel connected but at this time of evening that can be ignored.
If I can remember I will go out and see if the compressor is still running at about 20:15. Mine may run for a little less that most as I have an additional air circulation fan which is thermostatically controlled by the temperature of the pipework on the rear of the fridge.
Hopefully I'll keep you posted.
PS Forgot to say the fridge is set on the middle setting, i.e. third blue LED down.
Yea I only get the 1 red light when the volts have gone right down to below 11volts. Its sat quite happy at the moment. Or was when I come in at around 12.4volts and i put it on the coldest setting and was guna go back out in an hour and see what's happening. Then turn it to minimum and see if compressor stops. I think you can get 7.5amp fuses so maybe I will put that in. Or shall i try a 5. It was dipping Above and below 5 amps so might be alright although might blow after time. The cables are now 6mm so they wont melt before fuse blows.
Cheers mate. Mine is still running and temperatures were about the same. And solar was the same aswell as sun is now to low. Yea it has a fan next to the rad. The fridge is out at present so I could check volts on back of fridge aswell.
Compressor was still running. Volts at 12.68. Turned fridge down to minimum and volts climbed immediately to 12.78. I've left it on setting 2 now and see what happens over next few hours. But there goes my theory that thermostat wasnt working and compressor doesnt turn off.
So far it's doing what it should, mine pulls 6 a when compressor running. Did compressor eventually turn off or is it still getting down to temperature. I'm not sure when you're last post was as it's 6 20am here in oz.
Have you got something in the fridge or is it empty, it should have a few things in it,

Report on mine after two hours...
Time Batt volts - Current
0 minutes 12.5v - 4.9A compressor started
30 minutes 12.1v - 4.3A
60 minutes 12.0v - 3.9A
90 minutes 11.9v - 3.7A
180 minutes 12.2v - 0.1A compressor has stopped during the past half hour. No alarms on fridge.
Note that I have 180Ah of capacity in two batteries.
I've left the fridge switched on and will look at conditions in the morning.

Nice one. Out of curiosity how are you measuring load all the time continuously. I had to run fridge through my meter but you seem to be able to do it alot more easily.
I just checked volts and I'm at 12.40 at fridge and 12.48 at battery.
A good battery monitor is the easiest way, I have a victron bms702 connected via bluetooth to my phone, makes it easy to see voltage, current in or out, soc, ,power being consumed.
Wife thinks Im obsessed as I check soc of battery a bit too often when away in van

The fridge is empty. Why do I need buts it there? Yea compressor is kicking in and out now. I was hoping it wasnt and then i would find out problem. I've got my spare leisure battery on charge although it already had 12.6volts on it. I'm going to swap them in the morning as I'm sure by the morning fridge will be warm.
What's a battery monitor. Measures load and volts and is wired to battery?
A fridge with things in it cools down better than trying to cool an empty one.The things in it hold the cold better than air alone.
Your fridge appears to be working ok unless compressor is coming on too often, bad door seals or no ventilation etc, but it used to be ok when in van didn't it

That's what I'm so confused about. Its definitely got ventilation at the moment as its pulled out. That does make sense with regards to things in it actually. I've put some beers out of fridge into it. I sort of hope it stays cold but I'm sure it's not going to. Your up early. Is it saturday in Aus now?
See post 110 above
Yes Saturday morning, put a few cold beers in it then you have a good excuse to keep going out to check, putting prechilled things in fridge helps it cool down quicker than if empty

How did I not see all that. I just saw a good battery monitor and didnt read the rest for some reason. Nice one. I will Google that now
Just realised I have a victron 712, this one is bluetooth enabled, the 702 needs a Dongle, makes it simple to check battery
I assumed you had the 712 as it said bluetooth. I think I'm guna invest in one. Save me using the voltmeter constantly.
This what I am using to give you the above figures BM-1 Bluetooth Battery Monitor - Nasa Marine Instruments which I bought second hand from @Deaky
I'll have a look in the morning to see if the fridge is still OK and how the battery voltage is.
As above, it's at its most efficient when it's filled just leaving enough space for the cooling air to circulate. To be kind to our smaller camper fridges that are used occasionally we should fill them with pre-cooled produce.
Just to blow your mind, I often work in fridges which hold thousands of tons of cheese at 5 or 8 degrees and occasionally in a freezer which is at -25 degrees. No I don't stay in there for many minutes!
