Wondering if any body can fill me in.
I think my Gas Furnace has somehow inherited some strange ways.
Just recently I seem to have noted a difference in its operation.
here's whats going on. (blowing a lot of cold air)
-stat calls for heat
-fan comes on
-in viewing through the inspection window, pilot light is on.
-about 5 seconds after fan starts is tries to light a bigger fire and glows red for a couple seconds then dwindles back down to just the pilot light.
-fan continues to run for a minute or so, blowing cold air. then goes off.
- about every 3rd or 4th attempt, the fire does get going and I have heat.
Seems to me that the fan runing right away is not allowing the pilot light to ignite any of t he gas.
Its one of those things that you don't pay attention to it while it is working ok. So now that I think there is a difference I don't really know how it ran before and if there really has been a change.
Thanks
