Riello RDB burner lockout (Firebird combi)

[Stevie187]

You are very true a little understanding is a lot more dangerous. I'm sensible though if it's not the cap or other easily changeable device I will leave it to a pro. I would never mess with anything that has the potential to mess up the afr ratio or something like that and rich it out soot up the flues and gas my family out or lean it out and melt the boiler and blow them up! I have a good understanding of physics/electronics and know my own limits.

Hello Steve,
Afraid I have to agree with the above posts and say it could be a number of things and really should have a full service including a check on condition of the mechanical parts.
Replacing a capacitor with identical type for anyone competent enough is perhaps worth a try.
But there might be something else causing that to fail, or some other part altogether. The motor or oil pump but that requires analyser set up.

Doesn't matter what understanding you have. I'd you don't do it for a living then leave it alone.

So you wouldn't advise an end user to change a capacitor?

We could help you locate the offending part but once that part has been changed then the burner needs to be set up properly, using a flue gas analyser etc. That is to ensure both running efficiently but by no means least safely. Remember what I've said, call an engineer out and tell him the above.

Edit as only just seen above post. Do not increase the capacitance value of cap. This can cause the motor winding to burn out, amongst other problems

 

[Stevie187]

No I appreciate that but there's no way changing a faulty capacitor is going to have changed the combustion to the amount that the boiler would need re setting up.

I'm not trying to be patronising or clever. At the end of the day it's a combustion appliance, if not looked after properly they can kill.
