My heater does not come on and I don't hear the igntion click when I turn on the heater.
The a/c and the fan works fine when turn on, but no heat. Silent.

Could this be a faulty INTERMITTENT PILOT or a bad ignition moduel(circuit board).

My furnace is equip with the electronic ignition device.

Any inputs greatly appreciated and happy new year!

Since the heat is dead I suggest you trace the wiring through the heat circuit before replacing parts and also check for a good ground on the United Technology spark box (the gray box on the right side).
If I were to take a guess at the defective part causing this I would first suspect the United technology spark box. You might also want to clean or replace the flame sensor.

Make sure to check for voltage passing through the fan safety control located on the left upper part of the front. If no voltage there it will not allow the spark box to activate. Also many of these units were shipped with a white porcelain safety control also visible on the front of the burner area just up from the burners. That can also open and stop the control voltage from activating the unit.

Note if the porcelain safety proves defective you might want to check for a obstruction in the flue area since it is a roll out type of safety device.

One last note the numbers you posted for the furnace model are not correct. Those are the numbers from the spark box.
