There are only two wires for the motor. Up and down operation
is accomplished by reversing polarity to the motor on those two.
If it goes up OR down, the motor is just fine.
Sorry to hear you blew time on replacing the old one.
( But at least you've got a back-up.)

99.9% of the time it's a bad switch. Usually the master.
Did you replace your switches with new or used ones?
New will unquestionably eliminate that particular fail point.
Used is a crap shoot...

Here's a look at the circuit:
