Question about Heating & Cooling
It could be a thermostat problem. Also it will seem to run constantly as it tries to heat and one of the elements are working which could be a sequencer problem.

You should be seeing 120 volts to the igniter. Anything less requires either a replacement of the transformer, start relay or control module.

make sure the thermostat is in the auto mode if so it is more than likely the fan relay control some are built on the board some can be replaced separately

first off buy yourself a honeywell stat, in my personal opinion lux stats are garbage, I have run into so many that are bad stats !!! but as far as your fan not shuting down, sounds to me like your fan center on your circuit board is bad and will not shut down the fan when needed, you will have to replace the circuit board, as the fan center is a part of the whole of the circuit board, hope that helps

SOURCE: i have a coleman/evcon electric
Have you tried to replace pressure switch for the combustion air. If your not sure where to find it if you pull the front panels off follow the flue pipe down to combustion chamber the combustion fan motor is either inside the flue pipe or out side of it not sure on the one you have but you should see two plastic tubes that connect to a barb onto the topside of the fan and one on the bottom they both should go back to the pressure switch. i hope this helps you if you have any more question or if this doesnt fix the problem just reply back to this message . Make sure fan is working when furnace starts up. It should be the first thing that comes on when there is a call for heat

sounds like it is the pressure switch try jumping it out on some models you fool the heater in too working or see if the tubes are blocked , there should be some codes on the front panel or the fan panel
