[Stuart McLaren]

Oil furnace not igniting, today my oil boiler tripped the central heating fuse, once reset the boiler needed reset on the furnace control box(no coloured light), once reset the boiler blower etc is running, but not firing, there is no heat coming from the boiler and nothing heating up. the thermostat reset button is loose and cant be pressed

Potentially transformer and control box.
