S-16F 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 connec-
tions 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.
