What's up with my combi boiler?
Anonymous user 08/03/2024 - 2.30 PM
I have a boiler (Alpha 240p) that has a permanent pilot, so the fan stays on all the time - usually quietly when the radiators are off and there's no hot tap running. Recently I got the fan replaced because a blade had snapped, and the air pressure switch was replaced too. The fan now stays on full blow all the time and is noisy at night. Got a new pcb yesterday to try to solve the problem, but that fan is still running full blast. What can the problem be? It's like sleeping next to a tumble dryer, so I have to turn the whole system off at the mains every night to get a sleep. When my radiators are off it should be quiet. It always was before it was *fixed. Any advice? Thanks. --- Update --- Flamemaster Ltd. replied to me that my problem with my Alpha 240p could be with my air pressure switch. i.e. my fan isn't slowing down when heating is off, but stays at full speed and the noise is annoying at night when all the demand for heating is off, so I have to put it off at the mains to get some peace. Now, the engineer who's been fixing things did mention that he had to swop the wires to my air pressure switch because the "common" wasn't showing any signal, but the other wire was. * Could it be that he just wasn't putting juice through that wire at the time? I'm sick of phoning them (it's through Homeserve) and wonder that could be the very problem, and could I do it myself? Cheers. *He says his paperwork AND the diagram on my boiler both showed the black as common but he could only get things to work if he used the brown instead, (or the other ways around), or something along those lines. When I think about it, nobody told me I needed an air pressure switch, only that the fan was broken in the first place.
