Boiler making a firing up noise then off again..on again... off again..

[miss.cosmo]

Hi there, if anyone can help me I would be extremely grateful. My boiler is doing a strange thing, it is sounding like it is firing up, and then it goes off again, on again, consistently. Have no idea what to do, if anyone can advise me that would be wonderful. Thanks

Hi, would you care to give details of your heater/boiler, e.g, make, model, age, etc.

If it's an oil boiler on a conventional flue, has the flue been swept recently? Has it been serviced recently?

If it is an oil boiler the outside oil pipe may be partly frozen and not letting enough thru . pour hot water onto it if it has not thawed out by now .
