Hi,
My furnace won't heat. I tried troubleshooting, here is what happened so far:
Even though thermostats are calling (I have 2 zones), the furnace only sounds a few clicks and squeaks (like it always does before starting to burn and heat) but the fire is not burning after that like usual. Also the fan is not starting up at all. I opened the cover and saw that the pilot flame was out. Not sure why.
I then put the thermostats all the way down (so they are not calling for heat) and manually lighted the pilot flame. The pilot flame is burning all the time now.
Next I set the thermostats to high so they are calling for heat. I can see that the taco valves are opening (because I can move the lever manually easily unlike when they are not calling where the lever is very hard to move)
Pilot flame stays on all the time now, even if I turn off power to the furnace.
However, now when the thermostats are calling for heat, I don't hear the usual clicks and squeaks.
Furnace fire is not burning .only the pilot flame.
Any ideas on what's the next step?
Thanks
Shachar
