York Diamond 80 Does not stop blowing but will not cool or heat

I have a York Diamond 80 with the white rogers 50a50-241 controller. It is continuosly running and the controller is blinking 5 times telling me it is a rollout fault. This occurs even when in cool mode. I have tried to reset the rollout sensor with no luck. The fans kick on as soon as power is applied to the system and the LED blinks 5 times within 5 seconds.
I checked the voltage going to the condensing unit and when in cool mode it remains at 6mV and will not kick on the 26 VAC needed. This furnace originally was set up for LP gas and recently converted to Natural gas by replacing the gas valve assembly and nozzles. I have yet to get this to work and since then have not been able to get my A/C working.
Any suggestions would be greatly appreciated.

Who replaced your gas valve? You or an HVAC contractor. That doesn't sound like a DIY job.
What is your furnace model number?
How long did your furnace run after the new valve was installed?
