I have a Trane XL90 model TUC100B960A0. I turned the heat on

I have a Trane XL90 model TUC100B960A0. I turned the heat on and the purge fan kicks on but the igniter does not glow. I replaced the igniter and cleaned the flame sensor but still nothing.No light blinking on White Rodgers module 50E47-060. I have also checked the ohms on the vacuum switch and it tests ok and is working when the purge fan is running.The furnace was working perfectly all winter and spring. Went to turn it on tonight and no go. it will be 29 degrees tonight. Any suggestions?
