Thanks, Dave. Are they interchangeable?

The fan seems to be fine and generating whatever pressure differential the APS needs, at least on start-up. Trying to run with pipes disconnected doesn't sound like a good idea (even if that would fix the fault!). I'm just a humble electrical/electronics engineer (MIET but not Part P) whose...

Oops, it's getting late. You asked for my address. ********** Thanks, Neil.

Thank you, Dan. It's an Ideal Classic FF260. I can't find a serial number, unless it's this on the bottom of the spec sticker: MV 111121 9620 03073. Your help and interst is most gratefully received. Neil.

I'm grateful for your suggestions, and I'll look into those tomorrow. The Classic seems to be a good old solid long-lived reliable boiler. Has a circiut diagram and technical description been published anywhere? Thanks, Neil.

... and I should have said that the overheat thermostat is not triggered and all the PCB neons stay lit, and the fuse is OK.

I'm working from the Installation and Servicing guide that came with the boiler (10 years ago) and yes, in the fault condition, there is 240vac going to the pilot gas solenoid from GV1 on the PCB. At start-up from cold there is initially 240vac on the common (C, red) and normally closed (NC...

Hello, My Ideal Classic FF260 starts up properly from cold and runs for about 3 minutes then shuts down. After another 3 minutes, or so, it tries to start up again with the fan running and the igniter sparking but there's no pilot. The igniter and fan keep going until I switch off at the...
