I have a call in to PETA. Around these parts we take animal
abuse seiously. And how do you get the horse into the furnace?



Induction fan comes on pilot lights and stays lite for 90 seconds but mane
burners will not ignite . Thermostat works properly. Blower motor works
when put on fan. Back at the start of winter hade same problem. Removed
door in front of burners and it worked fine until two days ago. Wondering
if it mite be gas valve.

Yes, could be mites in the gas valve....


Seriously, I haven't seen a furnace where there are pilot
lights that get lit and then main burners. Don't see why one would be
made that way. Furnace I have,
the electronic ignition ignites that main burners directly.
There is no pilot light.
Have you put a meter on the gas valve for the main burners?
Does it get voltage when the burners are supposed to light?
