Also The new module has A flame And A sensor light which neither light will come on now!! THANK YOU:)

You need to keep your posts together

From my previous post back to you.

((Check for 120 volts coming to the furnace. Then check for 24 volts coming out of the transformer.Then make sure the thermostat is calling for heat. There might be a door switch that the blower door activates. They go bad all the time and stop the 120 volts from getting to the furnace. Check to make sure it is working. Post back with your results and we will go from there.))

Did you check the door switch yet as requested by my previous post?

You have spent a boat load of $$ with no results. Chech the door switch and if that is not it call a HVAC professional.

Also make sure the control voltage is OK, the fuse could be blown. Finding the fuse is in the sticky too.
