Goodman Condensing Unit GSX130181A

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

Disconnect ALL power before servicing

Tag and disconnect all wires from male spade connections of relay

Measure the resistance across terminals H1 and H2

Check for continuity across terminals 3 and 1

Check for continuity across terminals 4 and 5

Disconnect ALL power before servicing or installing

Fan Relay Cooling and Heating Check

Disconnect wire leads from terminals

Test between terminals 2 and 4 with an ohmmeter - should read open

Test between terminals 5 and 6 with an ohmmeter - should read continuous

Energize the relays with power ON

Test between terminals 2 and 4 with an ohmmeter - should read continuous

Test between terminals 5 and 6 with an ohmmeter - should read open

Temperature Test Lead Installation

Install a thermocouple type temperature test lead on the tube adjacent to the defrost control.

Insulate the lead point of contact.

Contact Closure Temperature Check

Record the temperature at which Part # 0130M00009P closes its contacts (2 and 2.5 ton units).

Is the closure temperature within 34°F ± 5°F for Part # 0130M00009P?

Record the temperature at which Part # 0130M00001P or B1370803 closes its contacts (3 thru 5 ton units).

Is the closure temperature within 31°F ± 3°F for Part # 0130M00001P or B1370803?

Record the temperature at which Part # 0130M00085 closes its contacts (units with 5 mm coils).

Disconnect all power sources before servicing or installing

Verify multiple power sources are disconnected

Check continuity across terminals of high pressure control with wire removed

Attach a gauge to the dill valve port on the base valve
