Goodman Condensing Unit GSX130301D

Disconnect ALL power before servicing

Disconnect the heater lead in wires

Using an ohmmeter, check heater continuity

Is the heater continuity test continuous?

Replace heater if continuity test is not continuous

Has the circuit protective device tripped?

Check the circuit protective device rating against the equipment nameplate

Disconnect all power to the unit, ensuring all power legs are open

Do not remove protective terminal cover

Disconnect the three leads going to the compressor terminals at the nearest point to the compressor

Discharge capacitor through a 20 to 30 OHM resistor before handling

Remove wire leads from the capacitor

Set an ohmmeter on its highest ohm scale

Connect the leads to the capacitor and check the condition

Does the indicator swing to zero and slowly return to infinity?

Does the indicator swing to zero and stop there?

Is there no reading on the indicator?

Remove the motor leads from its respective connection points and capacitor (if applicable).

Check the continuity between each of the motor leads.

Touch one probe of the ohmmeter to the motor frame (ground) and the other probe in turn to each lead.

If the windings do not test continuous or a reading is obtained from lead to ground, replace the motor.

Disconnect the 5-pin connector from the motor.

Check for line voltage at terminals #4 & #5 at the power connector using a volt meter.

If no voltage is present, check the unit for incoming power and the control board.

Check for 230 volts to the motor connections L and N

Is 230 volts present at the motor connections L and N?

Check the line voltage circuit to the motor if 230 volts is not present

Check for 24 volts from terminal C to either terminal 1, 2, 3, 4, or 5

Is 24 volts present from terminal C to the selected terminal?

Check 24 volt circuit to motor if no voltage is present

Determine if the motor needs replacement

Ensure the belly band is between the vents on the motor when replacing

Ensure the wiring has the proper drip loop to prevent condensate from entering the motor
