The furnaces vent blower comes on then no ignition of gas ,so it turns back off.? Does anyone know the Led Trouble shooting codes for this counterflow furnace? Model #45738-001.

I don't think that is the model number of the furnace. My best guess is a bad ignitor, usually found in front of the far right burner.

Con cord heater is to have trouble shooting red light.. red light not on and neither is furance help
