Question:
I overloaded the fan and it appears I burned out the circuit board. The part # in the unit is 10B21275K. You have a 10A21275K. What is the difference between the B and A part #s? Thanks

The correct replacement circuit board for your MaxxFan 7000k unit is the part # MA10A21275K that you referenced. The different letter in the part number is just a slight change they made but does not affect application.
