The blower doesnt work on my Lennox G32V furnace. The repair

Resolved Question:

The blower doesn't work on my Lennox G32V furnace. The repair guy tried a new motor - wired in but just sitting on the floor - and it turned over slowly for a second, stopped, turned over a bit more, stopped, and just continued that way. Now he's tried a new board (says Lennox doesn't make the original board any more so they sent a "generic" one). It wouldn't turn the old motor - and the same sporadic operation with the new motor - which is still sitting on the floor.
First question - does the motor have to be installed to work?
Second question - any idea as to what the problem might be?

ComfortZone :

Did he change the capacitor as well?

Customer:

No. Just the board and motor.

Customer:

It's a DC motor - with 2 "wiring harnesses" running to it. One with a few wires, and the other with a bunch of them. Would the capacitor be on the motor, or somewhere in the furnace?

ComfortZone :

no, none there as it is varibale speed motor.

Did they replace the end bell only, the motor only or the entire end bell/motor assembly?

Customer: replied 2 years ago.

Just the motor.

Expert:  A-1 Tech replied 2 years ago.

It is common that the end bell electronics are usually is what goes out

There is available a test meter to take the guess work out of this

I think it is called ICM 2 tester

But since the motor has been replaced, I am sure it is the end bell.

Are you still here?
Expert:  A-1 Tech replied 2 years ago.

This is getting really expensive for you, first a motor, then a circuit board. While there are generic circuit boards, I can almost assure you Lennox had a replacement board for your unit. I would be suprised if they don't. They do however change boards fairly often and at times you may need a conversion kit.

If I can be of further assistance please let me know.
