What do you do when your boiler light goes out?

If your boiler has a faulty pilot light you should immediately call professional heating engineers. It could be very dangerous since if the pilot light goes out, the boiler could still release the mains gas into the atmosphere and could pose a carbon monoxide poisoning risk.

How do I know if my boiler diverter valve is bad?

The most common symptom of a faulty diverter valve is when you don’t get any hot water to your taps and showerheads. The water gets luke-warm at best, but no more. This means that the boiler isn’t prioritising the hot water to the fixture in use, because the diverter valve is stuck open and the heat is escaping.

Can a fan blow out the pilot light on a boiler?

Most people think that strong winds can blow out the pilot light on a boiler, but that’s not usually the case. The air pressure switch wants to recognise air pressure being pushed out of the boiler by the fan, not backwards, into the boiler.

What should I do if my boiler fan is not working?

If you can see a fault code being displayed and it relates to a fan fault, your boiler should lock out. If it’s not locking out, there’s the potential for your boiler to be dangerous. Whilst it’s likely a Gas Safe boiler repair company can fix this quickly, it’s worth turning off your appliance in the meantime.

Why is the air pressure switch on my boiler not working?

Assuming there’s no blockage or fault with your boiler fan, it’s likely the air pressure switch needs replacing. If all other options have been exhausted, the PCB could be to blame. This gives and receives signals to parts in the boiler, including the fan. If the PCB isn’t working, it won’t receive the correct signals.

Why is the fan not running in my gas furnace?

A fan motor that runs normally after helping to start by turning by hand usually indicates a bad capacitor. Some older gas furnaces use a heat-activated switch to energize the blower motor after the burners ignite and the heat chamber warms.

Is there pilot light on a Promax boiler?

Ignition is electronic, as with all condensing boilers. This means there is no pilot light running 24/7 wasting gas. I’m encountering the Promax more often these days, which is unfortunate because I don’t like them. It’s worse than that actually, it’s one of the few boilers I avoid working on whenever possible.

How does the boiler work in Potterton Promax?

1) Random and intermittent failure to light. when this happens, the user needs to press the ‘re-set’ button on the front panel of the boiler, then it appears to work again normally for a random amount of time until the next failure.

What happens when you dismantle a Promax boiler?

Secondly, dismantling a Promax for servicing properly can lead to serious difficulty re-assembling it in a leak-tight manner in my personal experience. To service this boiler properly the aluminium combustion box base must be removed for cleaning. This part collects the acidic condensate and routes it to drain.

Why is the pilot light on my boiler not working?

Most people think that strong winds can blow out the pilot light on a boiler, but that’s not usually the case. The air pressure switch wants to recognise air pressure being pushed out of the boiler by the fan, not backwards, into the boiler. When it recognises this issue, it effectively tells the PCB that the fan isn’t working.
