Our forced air gas heating furnace is not working. It was fine all last year and for a few weeks this year but last night it stopped working and all i can hear is a buzzing noise coming from the item in the picture (see red arrow).
Last year we had to replace the Honeywell control panel / board (you can see part of it in the photo several inches above the arrowed unit) plus we cleaned some igniter / sensor head in the flame area and everything started working again.
What was odd was the red arrowed unit kept running and running when the furnace was on or off. The furnace could be off for several hours and this unit would continue to run. I was always saying because this thing was constantly running one day it will fail. Well today it is just buzzing and the furnace does not kick in.
Firstly, what is the name of this unit and could it be the cause for my furnace not running.
If it matters here are some #s i pulled from the top of the unit:
Model #: HCS2-750
Serial #: 14915HCJN
