Boiler issues

I am having issues getting my Utica Mgb series biker to ignite. Replaced the thermocouple today. The pilot stays lit, can hear the thermostat click and then nothing. Any ideas for a very green repair woman with two young kids who is freezing?

    Do you have just one thermostat? Does your boiler also make hot water for your showers? Oil or gas? Pictures of the boiler might help.

    Bad ignition control module.
    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    Two btu per sq ft for degree difference for a slab

    If a standing pilot with thermocouple, perhaps no ignition control module.

    Pictures needed.

    If it's an older model, you may be right.

    If it is a standing pilot, with a Basso control, I have noticed that the sheet metal cover can bind with the button, preventing the button from popping out completely as you light the pilot.
    I replace the thermocouple a couple of times before I figured that one out!—NBC
