I am in a apprentice class where people in other semesters rig the furnaces not to work so we will have to figure out what is wrong with them, and I am really stuck on this one.
I have a Honeywell Universal spark ignition module that doesn’t seem to be working right. When 24 volts is applied I instantly get 24 volts at everything both MV and PV and my gas valve dose not open and no spark. I cant seem to find any wiring diagrams or anything about a sequence of operation or anything on this thing and don’t really know where to start. I did not get to look at it very long and wont get to see it again until the end of the week but I would like to have a good Idea of how this thing works to test it rather than just say it is bad and replace it.
The only thing I can say about this thing for sure is I defiantly have 24 volts applied to it and I get 24 volts out
what I find odd is that I don’t get first a 24 volt signal to just MV but everywhere and the other thing that really kind of blows my mind is I don’t see any 24 volt common anywhere only a ground.
Anyway as you can tell Im lost, I could ask my instructor and I am sure he would help, but I don’t have class again until the end of the week and I would like to go at least somewhat prepared.
Can anyone help??
