SERVICING

S-16C CHECKING ECM MOTOR WINDINGS

APH15 M Series Only

1.Disconnect the 5-pin and the 16-pin connectors from the ECM power head.

2.Remove the 2 screws securing the ECM power head and separate it from the motor.

3.Disconnect the 3-pin motor connector from the power head and lay it aside.

4.Using an ohmmeter, check the motor windings for continu- ity to ground (pins to motor shell). If the ohmmeter indi- cates continuity to ground, the motor is defective and must be replaced.

5.Using an ohmmeter, check the windings for continuity (pin to pin). If no continuity is indicated, the thermal limit (over load) device may be open. Allow motor to cool and retest.

S-16D CHECKING GE X13TM MOTORS

GPH15 M Series Only

The GE X13TM Motor is a one piece, fully encapsulated, 3 phase brushless DC (single phase AC input) motor with ball bearing construction. Unlike the ECM 2.3/2.5 motors, the GE X13TM features an integral control module.

Note: The GE TECMate will not currently operate the GE X13TM motor.

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 to step 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.

HERMETIC COMPRESSOR ELECTRICAL TERMINAL VENTING CAN BE DANGEROUS. WHEN INSULATING MATERIAL WHICH SUPPORTS A HERMETIC COM- PRESSOR OR ELECTRICAL TERMINAL SUDDENLY DISINTEGRATES DUE TO PHYSICAL ABUSE OR AS A RESULT OF AN ELECTRICAL SHORT BETWEEN THE TERMINAL AND THE COMPRESSOR HOUSING, THE TERMINAL MAY BE EXPELLED, VENTING THE VAPOR AND LIQUID CONTENTS OF THE COMPRES- SOR HOUSING AND SYSTEM.
