Goodman Condensing Unit GSX130241D

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 heating element functioning properly?

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

System Operation and Pressure Check

Disconnect all power before servicing

Disconnect the heater lead in wires

Check heater continuity using an ohmmeter

Is the heater continuity test result continuous?

Heater Specifications Verification

Verify the heater is a 40 watt 265 voltage heater

Start the system and switch operation from COOLING to HEATING cycle.

Did the valve change its position?

Voltage Testing at Valve Coil Terminals

Test the voltage (24V) at the valve coil terminals while the system is on the COOLING cycle.

Is voltage registered at the coil terminals?

Thermostat and Wiring Check (Legacy Systems)

Is the system a legacy wired heat pump?

Check the operation of the thermostat.

Discharge capacitor through a 20 to 30 OHM resistor before handling.

Remove wire leads from the capacitor.

Set an ohmmeter on its highest ohm scale.

Connect the leads to the capacitor.

Assess the condition of the capacitor based on the ohmmeter reading.
