What should happen is this:
The thermostat calls for heat.
The inducer motor fan starts up.
The hot surface ignitor glows white hot
The main burner gas turns on and lights off the HSI.
The blower fan turns on.
Your description isn't clear, but it sounds like the HSI gets hot and you can hear the gas valve click to turn the gas on, but it doesn't light. (did not get hot - nothing)
What is the yellow and green you mention? I have no idea what that refers to. (Led light on the control box that the wires are hooked to (MV HSI etc)
Assuming my description is describing what is happening, check to be sure the furnace gas valve is turned to "on," and that the manual gas shutoff valve to the furnace is on (in line with the pipe. (Yep, first thing I did, just in case)
Is this natural gas or propane? You need to be sure your gas supply is turned on and that you have a supply of gas.
Do you have other gas appliances --- are they working?
(Another thing I checked right away, and had dryer and hot water heater going - both worked)
Can you hear or smell gas coming out of the burners after the relay clicks? |
No, I did not smell gas. Thing is - I thought I should have when I heard the clicks, but nothing. I have a good smeller too. But, then I thought maybe it wasn't going to get there if something else was telling it there was something wrong. (another safty device?).
I have in operating now, but I am still concerned. See my post below (or latest one on the flames I see)
And, again - I apologize for not being clearer. It's all in my head, but it doesn't all get out like I plan.
