He also told me this is a very common problem in the Villages due to voltage spikes in the electrical line which reaks havoc on the low voltage motor module, and that my whole house SECO surge Mitigator will not protect it. SunKool does offer an HVAC surge protector (<$200 P&L) which should protect against such voltage spikes. I'm thinking it might be a good investment once my unit goes off warranty.

Apreciate the update, good news it was covered under warranty.
As far as I know, the HVAC surge protector is installed at the disconnect box at the compressor. While a good risk reduction for the outside unit, it would not provide as much protection for the blower motor control as a whole house protector.
Those failures are more likely due to infant mortality or a component of a design flaw.
