 |  "Furnace Woes"
, posted Sun 24 Oct 16:26  
I have a Lennox Pulse 21 Furnace, Model G2104/5-100-3 (approx 11 years old). I posted a message 16 June 04 regarding heating and AC problems. AC response was right on and had a cool summer. Thanks.
I replaced previously the spark plug. Now with the chill in the air, I ordered a replacement ignition control circuit board 60J00. I replaced it as well as the wires that go to the spark plug and ignitor. Unfotunately, I still have no heat.
When the thermostat is set to come on, a motor would sound as if it was coming on. The unit gets hot but the blower never comes on and the limit control trips. If I set the thermostat to on, the blower does come on.
Any recommendations would be most appreciated.

Look on the blower control board. What are the led’s doing?
Xenos.
The best way to escape a problem is to solve it.
