"AO" Error on Hayward H400IDL2 Heater

Actually, my bad - I just went and found the post I did several years ago and it turns out I did originally have a 115V motor, so there shouldn't be any issues with voltage or wrong parts. I did replace it with the PN mentioned above (IDXL2BWR1931) which is the kit with new motor & control board that was recommended to me by Hayward in this thread: Hayward H400IDL2 Heater AO Code - bad blower

But come to think of it, the control board that I've swapped it out with was one that I had in my pool parts cabinet - and I think that may actually be the original board which was used with my old motor! There was nothing wrong with the board so I kept it. I haven't tried the heater with the board that came with the blower/board kit since swapping out the new vacuum switch, so I'll try that and see if there are any changes.
