Goodman Condensing Unit GSX130481B

Disconnect all power sources before servicing or installing

Disconnect power to the air conditioner or heat pump

Disconnect the sensor from the unitary (UC) control

Connect an ohmmeter across the sensor terminals and record the resistance

Is the sensor resistance within the valid range (9kΩ to 11kΩ)?

Replace the sensor if it is open, shorted, or outside the valid resistance range

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.

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).

Does Part # 0130M00009P close at 34°F ± 5°F?

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

Does Part # 0130M00001P or B1370803 close at 31°F ± 3°F?

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

Disconnect all power before servicing

Remove heater element assembly to expose fuse link

Test across the fuse link for continuity using an ohmmeter

Replace the fuse link if necessary

Determine and describe the reason for fuse link failure

Disconnect all power sources before servicing or installing

Disassemble and remove the heating element(s)

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

Test the element for continuity using an ohmmeter

Is the element functioning properly?
