should we get an engineer to check the gas valve or is it something we could do? What would we need to look for?

Noticed that the heating hadn't come on so went to see if boiler had locked out. No fan noise. Turned the boiler off and then on again by turning the switch inside the boiler to 0 and then back to 5. Nothing happened. Then noticed the programming unit had gone off as the fuse had blown...

I have an Ideal Minimiser SE which is approx 3 years old. Three weeks ago the PCB (PCB 41) blew and was replaced. The fuse in the switch that powers the boiler also fused. This fuse has now gone again and we are without heating and hot water again. It is a 3 amp fuse - could we put a 5 amp...

We have an Ideal Minimiser SE boiler which is approx 3 years old. About 9 months ago, we had a problem where the boiler was not lighting. We installed a new circuit board and since then everything has been fine. However, now we have neither heating nor hot water. The timer is on, the...

Thanks for this advice. The heating engineer came out today and I now have to do a couple of checks the next time the intermittent fault occurs just to be sure it is the boiler at fault. I have sourced a PCB 41 on line at £55 + VAT which he says is very cheap and would be prepared to fit a...

Thanks for all your help. We had the boiler serviced in November and everything was fine for 6 weeks and then it started not coming on in the mornings once or twice a week. Is there anything I can do to stop condensation? The whole system is less than 3 years old. Reading through the...

That could be it..The boiler is in the garage and there is a thermostat next to it - at least I think it is a thermostat - identical to the one in the hall but no temperature markings. The cold water tank is in the loft/rafters above the garage. However, could this be connected with the...

My central heating came on in the middle of the night even though it was not timed to be on. When I checked the timer, the timer was not on. The timer came on as usual at 6am and turned off as usual but the heating is still on although I don't think the water is (the motorised valve is shut)...

We have an intermittent fault on our heating and hot water - it sometimes fails to come on in the morning. The timer is switched on and there is a humming type noise in the airing cupboard (where the timer is) but no heating or hot water. If I turn the timer off for both heating and hot water...
