Question about Heating & Cooling
Hi, Have you determined if you have power to your ignitor first of all? The boiler control light is flashing 4 times due to an error, do you have a chart that tells the codes on this boiler? The first thing I would check if you have a meter, if not try and get one is to find out if you have power at this ignitor module. If you do, more then likely the ignitor is faulty if its calling for heat. If you have no power, you would need to go back to find what supplies power to the ignitor. It should be the control stat that does this. Its a process of elimination at this point to track down why the module/ignitor is not firing on a call. If you have any kind af manual or schematic to look at, this will come in handy to find out what is going on, and what has failed in the system with the 4 flashing code lights. Try and get a meter and check for power to narrow these controls down, you may just have a faulty ignitor as they are normally the first part to fail. Please keep me posted.

PS, check all of your safeties as one may have the ignitor locked out.
