Cant see your thermostat wires where they are connected at on the board, If you jumper from r terminal to w terminal the heat should come on, If it does you have a problem with the wiring or thermostat

Lennox Elite Gas Furnace - No Heat (LEDs show "normal operation")
I have a Lennox Elite series Gas furnace that we just tried to fire up for the first time of the fall season here in North TX. Here is the issue i am having:
When system set to "HEAT" and Fan set to "AUTO", nothing happens at all. I can set the Fan to "ON" and it will kick in and blow air, but the furnace does not light up at all.
I have opened the furnace door to check the Status LED lights, both Red & Green lights blink Simultaneously Slow (1 sec interval) which the sticker inside the door says "Normal Operation".
Does anyone have any advice on how to trouble-shoot this problem? It is below freezing for the next few days and my HVAC repairman is pretty backed up, won't be here for a few days.
Thanks.
Location: Dallas, TX
Outside Temp: 30 degrees
Inside Temp: 60 degrees (and dropping)
