For anyone that's interested in things eberish....

My eber wont stay on for very long - it gets worse when the weather is sub zero. When its not that cold i can leave it on level one all night - but when it gets cold it wont even last long on that (any higher than that and it will only stay on for 10 mins)

Well, just took the van down to Cambridge's BT Fleet (thank for the heads up Big Tam) and they stuck in their diagnostic tool and read out the error codes.
All for a tenner into their tea kitty

All five of the error codes were 012.

Now their manual says this error is "Overheating - open circuit on fuel metering pump". The causes/remedy are "Check inlet and outlet of heater ducting for blockage/damage, remove restriction as necessary"

The manual i downloaded from Espar is "Overheat" and the cause is "Check for possible overheat causes, check overheat switch resistance values".

I've got a suspicion (as suggested by Mocki last week) that i need to check the overheat switch....

Also possible that the fuel pump isnt exactly working tip top - which may explain why the problem gets worse when its below freezing...

I hope i can get this sorted out soon.....

Ringo, glad the info on my BT Fleet mates was of use, when I had mine done the chap said he cleaned out the filter in the pump as this was causing a restriction on the fuel flow, might be worth a look,

Thanks dude - but i already tried that

I've tried a lot....

so 012 is over heating?
have you looked at the heatexchanger? is it full of fluff and stuff in the fins?
mine was, but i still have the same problem.....still......

its the flame sensor......i'm convinced........ must check the price and availability....

Sweet Jesus - £43+VAT for a new overheating sensor.

I might just have to bite the bullet

I really hope that that fixes it....

Ringo

how frelling much?
where from?
thas too frelling silly........

there must be a better price than that........... must be must be must be

Check for possible overheat causes

thats wot i said

turn it around

Mark - you are right in one respect im sure - however, it used to work fine in exactly the same setup. At the Duke (and the same in the Alps in winter) it wouldnt even work on the lowest setting for more than 10 minutes.

Im going to turn it round during the xmas break to settle that argument once and for all.
Im also going to strip the thing completely - check the resistance of the thermal sensor (should be 1k1 ohms) and clean it of all carbon build up.

If that don't work, its going to be a new thermal sensor.

If that works im going to sodding well setup a company that mends the damn things because i will know about them inside out by then....

Ringo

PS Only two nights in it this week - hopefully it will work on the lowest setting else im going to have to go to the pub
PPS. Mocki - the flame sensor and the overheating sensor are two different components!

do one thing at a time then you will find the answer ,

i'm not saying i'm right , it was just what i thought

i know they are two diffrent sensors, mine is the flame sensor i think..

keep us posted.......

Right - this is going to be a pain for me but i think im going to try it.

Both sensors (flame and overheat) have a resistance of 1k1 ohms under normal operating temperature.

Instead of shelling out £50 to find out changing one fixes the problem im just going to stick a 1k1 resistor on the end of the wires that normally go to the sensor (test one at a time). If that fixes the problem i have found the buggered sensor and i'll change it.....

Sounds like a crafty plan

can you pm me the numbers off both the flame and the heat sensors.......
i too may have a cunning plan, which may involve NOT spending fifty of your english pounds.......... just loads of cross referencing.....

For reference:

Flame sensor: 25 1895 99 35 00
safety thermal sensor: 25 1895 41 00 00

I recently overhauled my eber and i think i have a pretty good understanding on how they work. As i've had a few PM's about it and it seems to be a recurring theme on here i'm putting together a rough guide to how i did it and a few ideas on solving the dreaded cutout on start problem. Hopefully it'll be ready in a few days but at the moment the cruise ship i'm working on is heading to Antarctica so we're all flat out to make sure we're going to comply with the ferocious environmental regulations down there so it might be a little longer.

To be continued.........

PS : Don't spend £50 on a sensor. You can get all the thermostatic switches at Farnell for a few quid.

As usual Dave - your a legend!!!

Will wait in anticipation for that then.

Much appreciated,

Ringo
