If you have not already ,it would be worth checking the continuity of the wires in particular the ground/earth ones , the other thing, I suppose, that could be faulty is the ionisation probe but I do not know if this was the case what the effect would be.

Thanks but itās not even clicking

Hi Geoff checked all wiring and earths with meter
Did you manage to get your fridge sorted
OP

No still not working Iām trying to find out why the new ignition unit isnāt clicking when I apply the 1.5volts to it on the correct pins.
Must be a simple way to test it but no one seems to know and Ive exhausted all the help on the web?

The ionisation probe seems to control when it should spark as it sits in the flame and seems to stop the sparking when it is burning and allow it when there is no flame , are you able to find a way to test it or maybe it needs to be in the circuit to allow sparking.

There maybe two types of electrodes present in your gas boiler: ignition electrodes and flame-sensing electrodes (sometimes also known as an ionisation probe). The ignition electrode, as you can probably guess from its name, is responsible for creating a spark that will ignite the gas supplied by your boiler. The ionisation probe acts as a safety device. It is able to sense when there is a flame present in the burner. If it cannot sense a flame, it will turn the gas off to prevent the boiler from supplying gas that isnāt being burnt.
The problem is Iām not getting a spark nor the gas to create a flame so I believe the ionisation probe isnāt in the equation at the moment .
I will try and force the situation by operating the gas valve with 2.5v battery and using a lighter to get a flame at the gas burner and see if the ionisation probe will allow the gas to be maintained

I Know this might sound daft but have you checked out the the three way switch to turn it from 12v to gas. Is ignition unit getting supply.

Hi yes I did change the mes pcb out, it does supply the voltage to the ignition unit

why are you adding battery power to your system? you need to ascertain where the existing 12v supply is failing

I have 12v at the fridge mes pcb, the 1.5v is applied by the pcb when switched to gas to drive the ignition unit

Just thought I would let you know I have fixed the fridge, it turned out to be a combination of both pcb board and the wiring harness.
Well done how did you manage to identify the faults
OP
OP
I removed the terminal plug from the igniter and at close inspection noticed 2 of the pins were broken so I made up a new connecter and tested continuity with a meter, as it still didnāt ignite I changed the fridge pcb as I didnāt believe the sense wire was working for the thermostat to the igniter and hey presto 
Good to know for future reference. Glad you got it fixed.Subscribers do not see these advertisements
Apologies to drag up an old post but I just wondered if there is any chance that you still have the old ignition unit and would consider to selling it Chevy?Have changed the unit without joy
OP
OP
Possibility I may have it still, Iām camping but back next Tuesday after the Newbury event and will give you a shout, if you pay postage Iāll send it you can send me half cost price if it works for u
OP
OP
Will check when I get back on MondayThat would be great if you still have it.
OP
OP
Hi have it still wrapped in its box, can you confirm itās correct for you?Will check when I get back on Monday
Looked on line and cheapest I could find available to buy was Ā£195 ?
Some really silly prices online for some reason
Let me know if you find it cheaper but I will only charge you half price as your on our group
Kind regards

Thanks for that but ouch! Before we left for the Newbury show I re-wired all the pins to the unit. I did this 6 years ago to fix a similar problem. I didn't really expect it to work again but the new connectors did the trick and it worked flawlessly all through the show so I think I will leave it for now because the fridge is 17 years old and must give up the ghost completely at some point.
I don't think you will have any problem selling that unit for a good price on ebay because as you said the prices have gone mad and there appears to be little or no stock even if you do pay up! Thank you though for your interest though.

No problem, exactly what fixed mine in the end, poor connectors , hope it keeps on working, I will advertise it as I completely forgot I had it until you asked lol
