Calling electrical wizz-kids ... 230v sockets & fridge lost power.

[icantremember]

On elh doing some tidying in the motorhome with just a 2 Kw plug in heater running .. for no apparent reason the heater stopped and there was no power at any sockets.
There is still power coming into the van via elh and both the consumer unit (all trips ok) and Eloctrobloc (EBL30) are live but still no 230v at sockets or fridge.

I don't think there are any trips or fuses after the consumer unit which can cause this so am guessing it must be a faulty cable or connection somewhere.

The Alde still works on 230v & the EBL is still charging batteries.

Any suggestions for finding this fault would be much appreciated.

The moho is a 2016 Hymer T668SL

Morning Brian.

Is there not a blade fuse at the EBL which covers the fridge?

I have read before where folks have removed the mains plug for the fridge from it's socket, to find corrosion on the pins. Cleaning and plugging in again has worked in some cases. Our two pin euro type plug for the fridge is in the wardrobe.

Good luck sorting it out.

Cheers,

Jock.

Thanks Jock, I've checked the fridge fuses, but these are only for the 12v as far as I can see.

The 2pin mains plug for the fridge is inside the lower fridge vent and seems to be fine.

I don't think a fault on the fridge (which was turned off) would affect the 230v sockets without tripping the consumer unit. I think the fridge is probably spurred off the 230v socket circuit which is where the problem seems to lie.

Hope to see you soon ,

Brian

Unplug hookup and inverter if you have one
Remove front cover from consumer unit and check tightness of all terminals.
Replace cover and plug back in.

Thanks John, have already tried all that but will have another look at the consumer unit connections.

Has the consumer unit more than one RCD? If it has, one of them may have failed. You could try tripping and resetting them all. If that doesn't work it's time to get the multimeter out.

Thanks John, only the one RCD which is working fine on the other circuits.

Failed MCB?

Failed MCB?

That's a possibility I will swap it ove when I next go to try and sort it.

Hope to see you soon ,

Ditto Brian.

One possible scenario is the 2kW heater drew more power than you normally take, and there is a bad connection that heated up, maybe lost contact when it cooled down. On my Hymer there were several mains wires from the MCB, maybe one or two not connected very well and worked loose.

Time for a meter and a length of wire for a continuity test.

I agree and think that's the most likely cause .. just need to find it now.
