Blower Performance Data
Checking High Efficiency Motors
The motor is a one piece, fully encapsulated, 3 phase
brushless DC (single phase AC input) motor with ball
bearing construction.
1. Using a voltmeter, check for 230 volts to the motor
connections L and N. If 230 volts is present, proceed to
step 2. If 230 volts is not present, check the line voltage
circuit to the motor.
2. Using a voltmeter, check for 24 volts from terminal C to
either terminal 1, 2, 3, 4, or 5, depending on which tap is
being used, at the motor. If voltage present, proceed tostep
3. If no voltage, check 24 volt circuit to motor.
3. If voltage was present in steps 1 and 2, the motor has
failed and will need to be replaced.
NOTE: When replacing motor, ensure the belly band is
between the vents on the motor and the wiring has the
proper drip loop to prevent condensate from entering
the motor.
