Kukoo fridge issues

[Babylee41]

Does anyone have this fridge ? It was brand new it switches on fine etc feels cold on the driveway. But when anyone goes away in the van they say it goes warm & the food goes off. when we turn it on it starts cold but then a few hours later it’s warm. Any ideas why ? It’s run off the battery I believe. The only thing that works by plugging in the mains is the one plug socket we have. Everything else is off battery. Dont know why it won’t stay cold

It looks like a rebranded Sanjo 3J fridge like the one fitted in ours. It does work off the leisure battery, which is in constant charge whilst connected to electric hook up, or when the vehicle is running.

Is the amber light lit when it’s not cooling?!?

Check the instructions here:-

For some reason ours doesn’t charge the battery when on hook up. Hook up only allows a plug socket to be used in the van. It looks similar I’ve only got blue lights I haven’t seen any drainage pipes as those instructions show that Empty any condensate or overflow though

Sounds like you are renting the van out?
If the fridge door is being opened as frequently as many do at home it won’t stand a chance. It used to be called hunter gathering, now it’s grazing.

Normally there’s a plug option for the condensate line that often gets used in camper fridges, occasionally you might need to use some kitchen paper in the bottom of the fridge.

For the fridge to dissipate heat there must be gaps for airflow, normally in under the base (gap between rubber feet) and out at the higher back side of the fridge (behind) sink / worktop. The fridge manual should show this.

There’s a good gap all the way round & a void that goes into the cupboard under the sink which has a floor vent

The outlet vent needs to be at the top to allow convection, hot air rising.
There is also a finned heat exchanger on the back of the fridge, this must be clean, at accumulates dust. It’s is very fragile, clean with a soft paint brush.

Do you think this is an issue ? Maybe someone pushed it too hard and damaged it

It’s not great but that won’t be enough to stop it working properly.
It looks like a re-branding of a Dometic CRX50, exactly the same fridge / freezer.

I assume you’ve read through the manual and made sure there are no alarms and the the leisure battery and electrical connections are good?
If the fridge is running but still struggling - when it’s dark put a torch inside the fridge and check for light outside, if you can see light the door seal isn’t tight and the door hinges will need adjusting.

I’m still having an issue with the fridge. It turns on and starts cold by day end it’s warm. Not one of the renters has had a cold fridge or Been able to store food every time it’s been hired.

The vast majority of fridge problems are normally found to be leisure battery problems.
You haven’t confirmed if you’ve read the manual and done the fault finding or checked that the door seal is correct with the torch.

Nearly a year and you’re still hiring a van out with a duff fridge. Just put a new one in.

Did you do anything about the apparent lack of a convection path?

I know you shouldn't have to , but maybe take the freezer compartment out and run it as a fridge only , see if that improves temperatures

Still having an is

It works but something is happening. It was brand new put in. And obviously they are told it don’t work or they suggest they can get it working and try.

It may be that the wire isn’t thick enough and it’s a low voltage issue. Currently it’s cold with an amber light on which we haven’t seen before. There was some switch under the bonnet Which was off too. Going to see what it’s doing in a few hours.

Did all of these An amber light is now on Which we haven’t seen before. I think it’s a low voltage issue and needs thicker wire Someome is going to to test it for me. It was brand new and new conversion it’s still got the film on. Someone’s cut corners somewhere
