Goodman Condensing Unit GSX130301A

Check wiring visually for signs of

Use an ohmmeter to check continuity of any suspected open wires

Replace wires with comparable gauge and insulation thickness

Disconnect all power before servicing

Remove heater element assembly to expose fuse link

Test across the fuse link for continuity using an ohmmeter

Determine reason for fuse link failure

Ensure all power sources are disconnected before starting the procedure

Remove control panel cover to gain access to transformer

Check voltage across secondary voltage side of transformer (R to C)

Is there voltage across the secondary side of the transformer?

Describe any issues found with the transformer, wiring, or splices

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

Check the continuity between each of the motor leads

Check for continuity from lead to motor frame (ground) using an ohmmeter

Is there a reading from lead to ground?

Disconnect the 5-pin connector from the motor

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

Is line voltage present at terminals #4 & #5?

Pressure Control Settings Verification

Enter the current pressure in the suction line

Is the cut-out pressure approximately 21 PSIG for heat pumps or 55 PSIG for air conditioners?

Is the cut-in pressure approximately 50 PSIG for heat pumps or 95 PSIG for air conditioners?

Test for continuity using a VOM

Is the continuity as expected based on the pressure settings?
