Welcome! Here are some tips for using this forum.
HI- I have a Weil-McLain natural gas furnace, installed around 1997. Since the late fall, we have noticed that there hasn't been much heat coming from the baseboard heaters, but because we also have a gas fireplace, we didn't pay much attention until this weekend when the outside temp dropped below freezing. Then we wanted all the rooms to have a heat source!
We checked out the furnace and it is completely cold. We had a service person come out today. He first tried replacing the ignitor because the board was flashing the "vent" light, but that didn't fix the problem. Now he thinks that the UTEC 1013-10 Integrated Boiler Control Board needs to be replaced.
I think this is a really expensive part and the service person didn't seem very sure that replacing this part would fix the furnace. Does anyone have any ideas for me?
