hi all got a problem with the above mentioned boiler. i normally only carry out service and commissioning work but have been called to a break down. boiler smoking excessively changed nozzle pump pressure ok air setting set at 5. now motor has stopped you can hear a clicking and then a humming but the motor does not start. so question i have is if the motor is failing could this be the cause of the excessive smoke due to not turning the fan at right speed to allow sufficient air to be pulled in.any help much appreciated i will try to up load a couple of videos if i can.
many thanks

don't expect any help here chief as Ive been registered for a couple of years (gas not oil). But I had no help at all with a recent problem that I had with an oil boiler

Run that by me again?

Either the oil pump is seizing or there's mouse jam in the fan.

Check for mouse then run the motor with the oil pump disconnected.

i have checked the fan and thats fine whats got me is that it was smoking before it stoped. i have changed the nozzle as it had the wrong nozzle fitted but that made no diffrence to it smoking. any other ideas croppie please as i cant stick my fga in as it is at mo and im struggling

Check the airway route on each side of the fan. It would surprise you what can block the air and only takes a tiny bit of fibreglass insulation caused by mice to block the air adjustment internal door partially

Have you cleaned the primary heat exchanger and baffles thoroughly????

 

[Dave Walker]

i have cheked the fan but will check again. i did clean the heat exchanger fully after which i looked like i had just come up from the pitts. could the motor slow the fan if on its way out say as it break downs

As I said, I'd be looking more at the oil pump.
