[Resolved] 3j Sanjo fridge issues

[VW_T6Campari]

Hi All,
Do you know of anyone else with this fridge having low voltage issues?
It has worked fine for last two trips and was okay for the first two days of this one then stopped cooling and showing 1 & 2 flashes on the error code light inside the fridge.
I’ve had it on hook up feed and leisure battery but fault still the same.
Disconnected the AC hook up and waited at least five minutes then rebooted but fault remains.
Any help would be appreciated, thanks.

What's your leisure battery setup?

Any voltage monitor?

What's the LB voltage?

How is the LB charged?

Without taking the fridge out or getting a reply yet from the van seller I’m guessing the set up is no different from anyone else’s.
With the fridge on the leisure battery I’ve got 12+Volts. With hook up I’ve got 13.9v on the display panel.
The fridge stopped working when on hook up - displaying a “low voltage” fault on the fridge error code light.
I might have an educated guess that the LB feed to the fridge needs at least a 6mm cable, that way there should be no drop in voltage feed/power?

Have you got a sargant ec155?
Only asking as I had same symptoms and I'd inadvertently tripped the main power switch, so hook-up had no effect....

I was going to ask what charges the LB from EHU?

If it's a Sargent then that may be the issue...... Not enough power to run the fridge and charge the battery.?

Took the fridge out and found the feed from the hook up side had come away!
Works fine now.
