Has anybody had to reverse the rotation of new motors before fitting them on these?
Had a look at a bottle cooler and found both the condenser fans seized up so ordered some new ones. They are the open frame style shaded pole motors with the small plastic fans that just push on.
When i went to fit them i noticed the old fans terminals were on the right but the new ones were on the left, also the copper shading in the stator was on the opposite side to the old ones, but as the old motors were both siezed i couldn't tell which way they are meant to turn.
Phoned Osborne and they said that the motors should turn the correct way as supplied but also that they should suck through the condenser.
Had a look at the blade and for them to suck i had to reverse the motors, which is what i did and checked that the airflow was correct by seeing if a sheet of paper would be sucked onto the condenser, which it did.
