Anyone replace Hayward Blower Vacuum Switch?

[KevinMM611]

I just purchased a new vacuum switch for my H400IDL after getting the AO error code. I am hoping it is not the blower so we start here. I opened the package and the switch is clearly different, but I have confirmed that the part is indeed the new replacement. With that said I see that the two post connectors are located differently from the original part being replaced. My question is do the two wires that need to be connected go to specific connector posts on the switch? The new switch has the marking of NO and C next to the posts while the old switch has no markings.

The part number for the blower vacuum switch is IDXL2BVS1930. The first thing to check is the hose to the blower to make sure it does not have any cuts or has come loose. The blower vac switch just closes and completes a circuit. wires can go either side. Could also be a board problem or Fan. If the fan is starting up most likely not the fan.
