The Variable Speed Blower

This is an indication that the grounding is not adequate. Improper grounding is the major reason for variable speed motor failures. They must have a very good ground.

do all these vs motors being commented on carry a "x13" motor made by ge if so funny how ge cornered the market per response more to follow

X13 motors aren't VS motors. They are constant torque motors though. But don't vary their speed like a VS motor does.

The X13 motor has the advantage of being a less expensive blower motor to operate and will operate constantly at a lower speed for constant air circulation, but those are limited benefits of what ECM motors are really capable of.

A variable speed motor is the same as the X13 motor, except that it has a lot more control features that can greatly increase comfort and overcome minor system issues.
