Alpha 240P Hot water ok but NO central heating

Willsuccess · 3 Apr 2008

I have changed clock timer, but the central heating is still not work.
No light, no noise, no pumping, nothing happens after I switch to CH.
Is it going to be the main PCB problem?

I assume you changed the clock BECAUSE it was not working?

Have you got a room stat? If so that could be at fault.

Most likely to be a simple external fault !

The PCBs are quite expensive so everything else should be eliminated before changing the PCB!
