Hi,
It is possible that the new actuator is faulty. If you purchased it online, I have been seeing a lot of faulty parts.
Try this and let me know the results. Simply remove the actuator from the HVAC box. Don't disconnect the actuator from power. With it out, see if it responds when you change the temp request from heat to cool and opposite.
Also, make sure the actuator shaft is connected and doesn't come off when installing it.
Let me know what you find.
Joe
