Ideal isar no power

[anz]

Got an Ideal isar, blank display, not working at all, checked all the usual, power getting to boiler, etc.

Usual suspect pcb, changed both, no change fault still same.

Before me customer had one of them handyman plumber dudes to have a look, apparently it was working and showing a fault code, and then he touched it and blew something and ran off.

I don't know what he's done, I've checked wiring, etc

Anyone any ideas, for what it might be? Maybe something obvious I've missed.

Interesting, that's something I wouldn't have suspected at all.

I'll take a look into it.

Me either it was a guy in suppliers who mentioned it and I thought why not give it a try. Never had it again nor heard anyone else with it.

control pcb connector lead, if the isar has one loose/faulty, cant remember ideal models as i tend to avoid the blighters, as all to often the new pcb is also knackered!!

have you plugged the user control pcb straight onto the main board to ensure the link cable is not damaged?

Nope, will try that.

Have you checked to make sure the power coming in is the correct polarity? Has the fuse on the board? Has it tripped the main fuse board?

Checked that

Ye, could just be the display unit faulty. Are the jumper plugs all in the new board OK?
