Found the diagram that appears to be for your set and yes the cap is a dropper along with resistors for the series heater chain.
If the heater chain is open circuit it could be a valve or a resistor or the cap.
If its a valve or a resistor I would be very wary of replacing parts and running on the 220v setting until you are certain that the cap is not leaky or short circuit, you could blow something else.

Running the set on a variac or transformer at the 110v setting would enable you to see what is and is not working without risking blowing the valves.
