Customer Question
Hello! I want...

Hello! I want to replace the blower motor in my Lennox ML 180 with a variable speed blower, or if not that, a two speed blower. I added a humidifier system and it is blowing constantly and driving me nuts! Alternatively, I would just add a blower in the duct and connect that to the humidifier, not involving the furnace blower at all???

Contractor's Assistant: Did you check the furnace's filters?

Huh? They were changed a week ago.

Contractor's Assistant: Do you plan on doing the work yourself?

No way, José!!!!

Contractor's Assistant: Anything else we should know to help you best?

I used to have a Bryant and it worked fine.

Need the exact model number because there is different M180-???

Adding a blower in the duct is not going to work at all, it would just blow inside duct and would go nowhere.

Adding a variable motor would cost Mucho bucks $$$

2 speed motor Good, but there is a good chance its already got other speed but not hooked

Actually, your furnace has already a 4 speed motor.

Hook up your humidifier wire to control board terminal W and C, this way Humidifier will only work when heating cycle is on.
