Grant burner tripping circuit breaker

Ran out of kerosense last April. Got a fill up today. When I now switch the unit on it instantly trips the circuit breaker in the house that supplies it with electricity.
The burner is a Grant 50/90 outdoor model. The timer control unit in the house is a Merlin Guerin (?) I think as the name has been obliterated.
Have opened and bled the burner. Nothing seems obviously wrong inside it.
Anyone have any ideas on what might be wong.
Thanks.
 
Glenmaddy gave "specialists " advice before . Before exchanging the pump get an electrician in and he will tell you within 5 minutes what part of your boiler system is wrong . A pump could be stuck after not using it for a while, a circuit on an outside boiler could have become wet/damp , a plug might have become wet . These are questions of pennys , not €s. Glenmaddy : When giving advice on plumbing you state your interests .
The pump can be brought back to life by turning it manually with a spanner/allan key . The circuit board can be revived with a hair dryer -but leave that to the electrician . The plug and socket as well.
And it might be the timer . Exchanging it would cost around €20.- .Including tax and material . A (propably technically outdated) pump from Glenmaddy ? € 200.- ?
 
ouch! A career in the diplomatic corps is not beckoning

I have to say I have always found Glenamaddys contributions helpful (ditto Heinbloed).
 
Thanks all for the advice. Got a technically minded neighbour to have a look at it today. He was he thinks able to turn the pump motor with a screwdriver. When a lead to the circulating pump was disconnected the breaker held on and the burner fired up. So it looks like a pump replacement is in order.
Thanks again.

What do you mean by this?

Why pay an electricians call out fee?

What circuit board? There are none on oil burners or pumps

I suggest you improve your english if you wish to pontificate on matters that you clearly know nothing about.
 
Well , Glenmaddy, your specialists advice stated for example that condensing boilers don't work i.e. are not worthe it if running on a non-condensing mode . This was not true and you did not rectify that wrong statement of yours . Instead you have cited outdated and incorrect literature on the issue ( this book has disapeared from the shelfes in Waterstones and is replaced by better ones ) . Again : no correction even when told that your statement and the stated literature is wrong .
Why paying an electrician ? So the " plumber " can't sell surplus material dumped in Ireland because the world market has no need for it anymore .Heating pumps sold here in Ireland use many more times energy (electricity ) and waste much more fuel than modern ones available around the globe. The EU is educating Chinese engeneers how to increase efficiency of electric ( heating ) pumps . These training courses are funded by EU environmental funds .To curb world wide CO2 emissions . These Chinese heating engeneers are now better equipped with knowledge than their Irish counterparts .Who are still installing 120 watt pumps when a 12 watt pump would do the same job .And the good news for you : these courses are hold in English !
Your job is to sell and install outdated boilers without electrical circuit boards . As you have stated here on AAM . Because you don't understand how these modern things work , as you have stated here on AAM as well. How do you know that there are no circuit boards on oil burners ? Because you install only the old crap ?
See, my English is as great as yours, at least when explaining to some one that it might not be necessary to exchange the pump. The logical step to twist the pump manually was not recommended by you . Why ? My insight on what drives people to give "advice " is based on experience and memory - esp. in your case (smiley ) . Have you installed now a condensing boiler b.t.w. ? Will you ever be able to do so ? What's about a course in heating technology ? There are many questions asked and to be answered about the issue here on AAM . Give it a try , learn something new and share these news - for altruistic reasons, not to protect the dying horse .
 
Just to clarify about the circuit board, my oil stove in the kitchen (which does the exact same job as a boiler outside except it gives a nice toasty kitchen also) gave up the ghost on me 2 weeks ago. I might have been low in oil so filled it to the brimm with kerosene and called out the cooker guy for a service. My circuit board had blown and he told me that when anything like that happens, a trip-switch goes off in the cooker to prevent it from working and blowing up basically. Just as well it I needed a brand new circuit board, because I filled up with kerosene instead of diesel so he fitted a circuit board to suit kerosene instead! Cost me €212 for the new circuit & call-out.

I would also have to say that it's always money well spent to call out an expert to fix anything electrical or plumbing wise unless you're really handy on them yourself.

I gave my opinion combi boilers and referenced this with an article from the guardian.

Bull**it. A replacement circulating pump is exactly what it is “replacement circulating pump”

There is no circuit boards on oil burners, there is a control box. Big difference.

The pump is not seized, it’s an electronic fault on a throwaway item, a circulating pump.

Yes, see previous, I’m a plumber with an honours degree in engineering and systems sciences.
 
Do oil burners not use electricity? I'd be very surprised to find any such item that does not contain a circuit board of some description... What's in the control box?
