Goodman Condensing Unit GSX130421B

Disconnect ALL power before servicing

Connect voltmeter to lugs (L2) and (C)

Is power ON and call for cool or heat pump provided to energize the on-board compressor contactor/relay?

Measure voltage across on-board compressor contactor/relay contacts

Ensure short cycle delay has elapsed before making voltage measurements

Disconnect all power sources before servicing or installing.

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.

Check for 24 volts at thermostat wires C and Y in the condensing unit control panel

Is there voltage at thermostat wires C and Y?

Check the continuity of the thermostat and wiring. Repair or replace as necessary.

Set fan selector switch at thermostat to 'ON' position.

Check for 24 volts at wires C and G with voltmeter.

Is there voltage at wires C and G?

Check the continuity of the thermostat and wiring. Repair or replace as necessary.

Disconnect all power sources before servicing or installing

Confirm multiple power sources are not present

Disassemble and remove the heating element(s)

Visually inspect the heater assembly for breaks in the wire or broken insulators

Test the element for continuity using an ohmmeter

Is the element functioning properly?

WARNING: REFRIGERANT UNDER PRESSURE!

Charge the system with the exact amount of refrigerant

Refer to specification section or unit nameplates for correct refrigerant charge

Allow liquid refrigerant only to enter the high side using an ambient compensated calibrated charging cylinder

Close the valve on the high side of the charging manifold after the system takes all it can

Start the system and charge the balance of the refrigerant through the low side
