Capacitor is weak means motor is weak?

Hmmm somehow I don't think so.

Sorry Jack, If I've come across wrong again, but I was only explaining to OP in layman terms.
Hold the motor shaft, in my experience if the strength of the motor is weak ( different levels of weakness )
If capacitor is below 2 uf you'd hold/stop it with your little finger.
OP stated that shaft on oil pump turned freely but sometimes motor didn't it just hummed , but ran freely when it had no load with the oil pump removed, Most likely cause is capacitor, I just gave him simple DIY testing advice.
As he's only a DIY 'er,

Yes, we ourselves can get more technical where explaining things to each other, which is good, and helpful.

Sorry if caused confusion.
Lets talk politics, it's safer than capacitor.!
Thanks.

Who would want Gary's job with us lot around stirring it

Don't worry i'v been watching a box set of Jeremy Kyle.

So I figured out: arguing or contributing to a on going argument will end in tears.

Exchanging the vast knowledge that is obviously out there in a caring and sharing manor will lead to good karma for all.

But if we could make sure the OP is sorted before the games begin then that would be lovely.

Amazingly all the OP's questions have been answered here and no more help can be given to him until he rules out corrections that have been suggested to him. .................... hmmmmm lovely smell of roast beef coming from the kitchen..........Im off. :pac:

May god forgive you for suggesting that stirrers frequent this forum I would suggest your magna didn't work last nite and there is still a lot of sludge left over after all that Guinness

There is no conclusion yet and in fairness to the OP how many posts should be on his thread after he last posted by the time he comes back?

If a question has been answered then I think there's a bit of freedom to go off topic if we're mid fault finding then we should stay on topic and wait for the OP to come back.

At least it wasn't pumping over.

Ok Gary, that's my last off topic comment...................at least on this thread.

You are right about it being an inefficient way to use it. Yes it is probably that small cylinder (photo?) It is strange that it runs when you do that and will not start when left longer. It needs investigating, but the capacitor is a cheap enough item to try anyway. Just be careful with the contacts, they can pack a wallop if charged. Your multimeter may not have a capacitance meter on it. It is measured in Micro Farads (symbol a bit like yF).

Might just be a sticking pump. Was there any suggestions as to why the previous pump failed?

I was told by a plumber, a neighbour of mine that the pump needed to be replaced because the boiler and locked out and wouldn't restart. That was last January. Since this recent problem two weeks ago, he has tried the new control box and wired connection to the fuel pump. This guy reckons the motors don't usually give trouble and suggested it may need a new fuel pump. The boiler is dated 1997. I've been living in house the past 7 years and last January was the first time the boiler, fuel pump gave any problems. So the previous fuel pump had been there for 6 years+.

Motor doesnt give a lot of problems other than bearing which are normally apparent by the noise before giving up, the Capacitor is very common, and pumps are at times finicky and very reliant on good fuel.

Sorry about this JARBELL
Just check motor strength as I've explained, if its weak try a new capacitor.
If not call good service engineer. Ask boiler manufacture or oil company for somebody local and good, or tell us where you live and one of us might be able to help.
Let us know how you get on. Ta

scudo2 I think I'll get a new capacitor tomorrow and try that, especially as there inexpensive and I know the one on my burner hasn't been changed in at least 7 years.(it could be the original).

For your sake hope it is just a capicator but if not then pump would be next to eliminate after that motor bearings would also be a possibility. Ive had 3 riello 40 series with fcuked motor bearings this week

jimf I checked the motor bearings when I had the burner out,( fuel-pump out and fan housing off). They seemed fine to me with no play or signs of breakdown.when I do get the burner running as described (bit of fiddling)there is no noticeable bearing noise.

Good service engineer in Athboy if your stuck.
PM. crock! " Its his name here."

But his Mammy named him David.
He also does a 20% discount if you mention me !!!!!

Best of luck and let us know how you get on.
Thanks

You get 30% if you don't mention him at all

I say nothing so !!!

DGOBS · 08-12-2013 09:30PM

He's based near Kells, not Athboy. Sure he would like to help if needed, discounts were not authorised with him, any interaction as such should be kept too PM only.

Yelling discounts got you in hot water before, that an end to it, see you in a week.

JABKELL · 09-12-2013 10:21PM

Well today i went and got a capacitor,(the original one in the burner is dated 1997) fitted the new one but the problem persists. Fiddled around to get the boiler restarted, I knocked on and off the boiler a few times and did notice a strange sound as the fuel pump/motor slowed down. Thinking now I may need to get a new fuel pump. I didn't seem to get long out of the last one, its only in 11 months!! Or maybe contact a good service engineer as suggested above.

In my opinion, you should get a service engineer in as a fuel pump needs to be set to the correct working pressure to suit the make & model boiler. It would also avoid costly plug & play fault finding. With a vacuum gauge a partial blockage in the line be the cause of the failing pumps or water in your oil tank. A decent service engineer will be able to identify all of these. Problem could also be a motor issue.

You never got an explanation as to why the last pump gave up the ghost. Sometimes it is impossible to figure it out, but it is always necessary to thoroughly investigate it, because of the cost of the pump and likelihood of the new one also going the same way. I suppose in hindsight, it would have been better to have had a good boiler service person out originally, but if we all could see the future we would never make mistakes.

If it is the pump that's gone. Ask yourself these questions; do you regularly lift up back of tank to get last out of it? Do you buy small amounts and run out often? Do you buy from reputable sources? Have you a good quality filter on your tank? Has your tank been checked for water? etc.etc.

Billy Bunting · 09-12-2013 10:47PM

To be honest if its the original Mectron burner i would think about replacing it rather than throw money at it.

jimf · 09-12-2013 11:59PM

I'd be leaning towards motor bearings at this stage if the burner slowed noticeably at full revs not all bearings start noising before failure I could be wrong I was wrong once before I think twas back in 1995 I said yes when I should have said no

Hello guys
Im going to see this boiler on sat morning and i suspecked its the pump from further info with client.he says boiler smells off unburned fuel that wasnt there before.pump is week. Pump was changed in jan this year so i will check for water in tank.the burner is rbl but as far as i know there is shrowd around this burner which is a g5.to put in change a burner which is what i would perfer because of age wouldnt i be better with an rdb2.2 rather than changeing it to rbl which would be hassle trying to make it fit.i could make it back into bf with no hassle with rdb.
What do ye think?

jimf · 12-12-2013 12:11AM

if you haven't seen it yourself crock maybe your jumpin the gun a bit how does customer know pump is weak

could be something as simple as low fuel pressure or gammy nozzle

was it serviced when pump was changed and set up properly

it might be just poor combustion over the last few months had 1 last week and the fumes would cut the eyes out of you

customer could have been playing with it himself we know they say I never touched it in me arse they dont

He told me it was serviced by a guy who changed the nozzle once in three years.of course some one could of fiddled with it but that wouldnt give an intermitten fault on a start up with an unusual noise.he says when it wont start that he bleeds it and then it starts after doing this once or twice.

Sounds like a riello R40 G5BF shrouded.HWOS have one 15-26kw,maybe not big enough,expensive though

What nozzle is in it and is that whats always been in it ?

The later Statesman 70/90 did come with a RDB1.

could be a lot of things is the customer far from you

partially blocked filter maybe vacuum gauge would tell you a lot

No he isnt far from me.he says filter had a bit crap on it.i will check it for flow of oil.i think its water in tank damaged pump.new pump put in in jan
