Which way do I want the new fan motor to spin??  Red arrow??  Or blue arrow??

I think the fan blade is on backwards, if its like my big units, they pull air through the coil and push it out the bottom. Maybe this partly explains issues with this unit not working properly.

Unless who ever previously replaced the motor put the fan on backwards.

Yup, I agree. 

Wonder if they got the right rotation motor?

So I was thinking this is how the airflow goes. Sucks it in from the area under the steps and blows it out the side??
