Popping sounds are caused by arc faults. People hear them through speakers when turning on a light switch also.
Have the electrician check the wiring connections from the boiler ignitor to the control panel. There should be a black and a white wire from the ignitor to the boiler control box (120 volt). Sounds like you may have a loose connection. That sound you hear is from an electrical arc that is caused by a space between the wires and the connectors. The loose connection is either at the ignitor or the control box.
Also have him check all the boiler wiring from the boiler shutoff, to the 24 volt transformer and to the boiler control panel. It is also possible that the ignitor itself is bad. Or it's possible that the neutral or ground at the boiler switch is reversed. Or worse, the neutral is bonded to the ground screw. Just have him check everything - sometimes Joe the Boiler Man does his own wiring.
If that's not the case, have the electrician check to see that the boiler wiring is not "borrowing" a neutral (he'll know what that means). If it is, then a dedicated circuit for the boiler wiring may solve the problem.
