I have a Armstrong ultra 80 111 furnace that mane burners will not ignite.
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.
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?
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?
