Ideal Icos NO Display.... HELP

[joebaker1]

hi, i have an Ideal Icos HE 18 and recently its stopped working, there is no lights on the display and there is a 240v supply there, also no fuses have blown so i'm thinking it could be the PCB, but what would cause this to just blow like that

Many thanks, Joe

If its the old black PCB,or the early orange one,they were common failures,the later V9 board (also orange)is better

I there a bit of melting of the case on the top of the main module?

I got through over 800 ICOS transformers last year !

"the later V9 board (also orange)is better" ...couldn't really be worse

Some blame the fan joe, but i wouldn,t know, as i don't do that stuff.

The most common cause of no display is water leaking from the AAV onto the connection interface to the display PCB.

Sometimes that causes the PCB to fail as its not protected against overloads. Its almost as if they designed the AAV to leak onto that part and the PCB to fail so they could sell another.

Usually when the transformer has overheated you can see the layout of the laminations on the plastic PCB case.

There is also an externally accessible fuse on the PCB but if that has blown its normally because of a real fault.

If the fan stalls, it can draw more current than the driver transistor in the module is rated at.

Blows transistor and transformer

Tony - the transformer is there to protect the fuse - it invariably dies first

Joking aside (if that's possibly with the Icos), how do you find the v9 board in terms of failures compared to other (makes) PCBs?

A transformer there to protect a fuse.......well I never did. Please explain

Whoosh!

thanks for the replys chaps, so this v9 board, is it compatable with the Ideal Icos HE18?? is so how much are they? or would u recommend getting a new boiler to save on future hassle from this turd boiler??

 

[thomasm5]

no display can also be a fault in the connector on the underside of the boiler next to the pcb, into which the power cable plugs. in mycase,it turned out the original installer hadn't pushed it in fully (barely at all), so when the spark electrode was replaced, taking off the cover disconnected the power! Changed the pcb before working out what it was. This is probably uncommon, but worth checking
