Combi not igniting

[philfoo]

Hi all I am new here but here's the problem .
I have a 1991 Worcester 350 rsf combi, NG.. I know its ancient but I wont give up on it yet !

The boiler won't ignite (CH or HW) because the fan at the top isn't kicking in.
I have checked the voltage to the fan and its zero

I have gone through the troubleshooting procedure with a test meter and its telling me at the end to replace the main board.
I am pretty confident that this is the correct prognosis but I need to be sure before I splash out on a service exchange board.

Is there anything I might have missed in trying to remedy this problem before I go any further ???
Any help here would be very much appreciated
Thanks all.

I have a spare new fan for that model somewhere in my stock.

Was thinking there might be an opportunity for me to sell it.

Hi there.. I appreciate your offer, but as stated in the post there is no voltage going to the fan

Send your diagnosis fee to Agile considering he missed the bit about "no voltage to fan"..

Of course I had noticed that he had no voltage.

That's why I said that I "was" thinking there might be an opportunity to sell it.

Otherwise I would have sent him a PM and offered the fan. We are not expected to sell bits on here. That's what Ebay is for.

Tony you will have self powering fans that do not need voltage

Why would you offer the fan?...possibly a parts changer??

 

[AGAS]

i thought he never offered parts as he uses them for his full diary of customers . plus offering to sell parts on miss guidance

I bought it for stock when I was looking after three of them.

But that was a while ago and not expecting to ever have another customer with a failed one again. They are so old!

You looked after only 3 of a boiler, and you buy a fan, just in case? Are you mad?. The warranty deteriorates for you but not your (possibly eventual) punter.

When I did a LOT of repairs, my van was stacked with common generic gear, and I did carry one specific fan, but I used at least one every couple of months, as they were fitted on a massive estate and were a regular breakdown.
