Goodman Condensing Unit GSX130241B

Disconnect all power sources before servicing or installing

Ensure fuse, circuit breaker, and ground fault protective device have not tripped

Remove the leads from the compressor terminals

Review warnings S-17 before removing compressor terminal cover

Test continuity between terminals SR, C-R, and C-S on single phase units

Test continuity between terminals T1, T2, and T3 on 3 phase units

Disconnect all power sources before servicing or installing

Remove the leads from the holding coil

Test across the coil terminals using an ohmmeter

Checking Contactor Contacts - Single Phase

Disconnect the wire leads from the terminal (T) side of the contactor

Energize the contactor with power ON

Test across terminals using a voltmeter

Discharge capacitor through a 20 to 30 OHM resistor before handling

Calculate the capacitance (MFD) using the formula: 2650 X Amperage / Voltage

Remove the remote bulb of the expansion valve from the suction line

Cool the bulb in a container of ice water

Record the suction pressure after cooling the bulb

Record the suction temperature after cooling the bulb

Some models feature a solid state, delay-on make after break time delay relay installed in the low voltage circuit. This control is used to prevent short cycling of the compressor under certain operating conditions.

The component is normally closed (R1 to Y1 ). A power interruption will break circuit (R1 to Y1 ) for approximately three minutes before resetting.

1. Remove wire from Y1 terminal.

2. Wait for approximately four (4) minutes if machine was running.

1. Apply 24 VAC to terminals R1 and R2.

2. Should read 24 VAC at terminals Y1 and Y2.
