Replaced blower motor in 58MVP now it wont shut off


Hi,
I just replaced my blower motor it was a hd46ae120 GE ecm motor with the same motor but the only difference I see is the old control module said 2.0 and the new says 2.3 but the motor is the same. Why won't it shut off? Any advice would be appreciated. THANKS

Because its the wrong motor and module.

The 2.0 you had, is not controled by pulse width modulation, like the 2.3 you have wants.

Hi,
Thanks for the info, does the mvp's circuit board have anything to do with it? Would a new circuit board be able to use the pulse system?
Thanks

A new board designed to control pulse width, yes.

But, you'd be better off, taking that motor back, and getting the correct one.
