Lennox 80UHG3 Issues - Please help

Hello, I have a 80UHG3 that will not start the AC when i turn the AC to Auto or to FAN. I see Ice formation on the connections on the outside unit. THe outside fan starts up and the ice starts building up.
I replaced the air filter and that dint fix it.Not sure if its low on freon

I then tried to turn on the Heater and it appears to not work also. When i turn it on to Auto, It ignites and i see the red formation and then the blue flame going thorugh and appears to start.. but after a min or 2 it shuts off. I didnt hear any air blowing on AC or for Heater .

Any thoughts what could be the problem.can some one please help me troubleshoot if i can fix this myself?
