This s done by swapping some wires around.Tell me number on your new motor and I will be happy to help.
Variable speed motors can not be reversed by simply changing wires.Who told you the motor could turn both ways?
The bell control on the end is what controls the motor . Did you replace the entire assembly or just the motor (using your old bell control)?
Yes the has bolts connecting it to the end of the actual motor. The motor can be used in numerous applications and directions, but the bell must be unit specific programmed for your unit.
Did you provide the model on your unit when buying the motor?
If not the bell may be programmed incorrectly.
Can you look on the black bell and give me the number on he bell as well as the model on your unit it goes in?
I am suspecting they gave you a motor with the wrong bell control. The same motor is used with a number of different bell controls .For example when used with one bell control it will move a certain rpm and direction on a York where same motor with a different bell will turn opposite direction and rpms will vary.
You are most likely going to need to have them replace the entire assembly or get you the correct bell programmed specifically for your unit.
AS you will note in the links above, the motor is same but bell control is different.
If you can get me model on unit I can tell you what bell controller you need.
Hmm. The variable speed could be effected by static pressure.I have acutally seen an outddor start backwards because wind was blowing.I was not aware you were running without cover. Let me know if you have any more problems.
