Is Replacement Printed Circuit Board for MaxxAir Manual Lift RV Vents # MA10A21276K Current Version

Question

Question:

The part number shows as MA10A21276K, which isn’t the most current version of this part. That would be 10C21276K. But under the “Features” section of the product description, it implies that it’s actually the updated part see below. “10C21276K Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents Replaces 10A21276K and 10B21276K” I’m confused. Can you confirm which version it is? Thanks so much!

The Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents # MA10A21276K that you referenced is the most recent version. Right now that would be the 10C21276K but if it were to update in the future it would also update to that version and most likely still carry the older part number. Also, we don't have any older stock so if you ordered this you wouldn't have to worry about that either.
