I've got a Hayward H400FDN (up to October 2010 Model, according to the troubleshooting guide) and I am having an AO error after replacing both the display board and control board as well as the blower and vacuum switch.
Steps taken:
Any help would be greatly appreciated.

Steps taken:
- Jumped the vacuum wires and it changes to a AC error so the wiring to the switch seems fine.
- Tested the voltage and it's sending 128 to the new blower when a call is made but the blower isn't starting.
- If I trip the breaker while it's on the pool or spa setting then turn the breaker back on the fan spins up for 20 seconds or so but then shuts off with an AO error.
Any help would be greatly appreciated.
