Pull the blower assembly...2 screws on the angle bracket holding the blower & disconnect the wiring if needed to the motor.

Check for fan operation by turning the fan control at the thermostat to "on". If the fan blows, it works. If not, check a circuit breaker or fuse.

If the fan blows when forcing it on with the thermostat but not in automatic, check the fan control circuit in the air handler. Danger: high voltage, beware! There should be a system wiring diagram inside the air handler somewhere.

Thank you for using fixya have a nice day:-)

The Rheem model RHQA-0805B is a 6-ton unit.

Air Handlers differ in the way they adjust there variable speeds. Carrier you just plug into a pin. Trane has dip switches with directions on the fan housing. Before you try to adjust please kill power to air handler. Varriable speed are very sensative to voltage. If I new your air handler brand I could help. But just check the wiring diagram and they may ahve dirrections on there for setting speed. Need more help call back Rus

You can change the size of the pulleys. Either increase the fan pulley size or lower the motor pulley size. Don't go more than 1 inch at a time. You will also have to change the length of the belt. The motor runs at 1725 rpm's.

Have you hard wired your fan motor to verify that the motor and or the capacitor are good? If you do a continuity test of the motor leads(with electricity off of course) you can see if the motor has open or grounded windings.

We tried to bypass at the Tstat. Thanks for your time and interest.
