  To address a fan motor error on your GE Air Conditioner, start by inspecting the DC fan motor wiring. If there's an error, correct or repair the wiring according to the wiring diagram. You might also need to replace the fan driver board. Additionally, check the CN8 port of the main PCB. If none of these steps work, consider replacing the fan motor.

- Default setting: Unit stops if T3 (condenser temperature) exceeds 149°F (65°C) and restarts when T3 drops below 118°F (48°C).
- Alternative setting: Unit stops if T3 exceeds 154°F (68°C) and restarts when T3 drops below 126°F (52°C).

Maintenance Features:

The manual emphasizes safety notifications for both maintenance and operation.

Safety Notifications:
- Prohibited: Do not pierce or burn, mix refrigerants, modify the unit, or operate with worn wires. Ensure proper ventilation during refrigerant leaks. Disconnect power before maintenance.
- Warning: Wear safety gear for high installations. Test for leaks before charging. Isolate power for repairs. Maintain a regular schedule for preventive maintenance.
- Notice: Requires proper earth ground. Do not repair with wet hands. Isolate power before cleaning. All field wiring must conform to codes. Brazing/welding must be done in ventilated areas. Keep fire sources away. Clean with soap and water only. Do not remove fan cover while running.
- Observed: Check condensate drain outlets. Unit must be installed level and on a supportive surface. Disassembly and refrigerant handling must follow local rules.
Troubleshooting: The manual provides detailed troubleshooting flowcharts for common issues:
- Fan Motor Not Operating: Steps include inspecting wiring, checking the fan capacitor (capacitance values provided for different models), and replacing the fan motor or capacitor.
- Compressor Not Operating: Steps include inspecting wiring, checking the compressor capacitor (capacitance values provided for different models), and replacing the compressor or capacitor.
- Both Fan Motor and Compressor Not Operating: Steps include verifying voltage, checking contactor pull-in, and troubleshooting the discharge temperature switch (FT) and high-pressure switch.
- T3 Condenser Temperature Sensor (UUC136WC/UUC148WC Only):** Troubleshooting involves checking sensor-PCB connection and sensor status (open/closed). For 36/48K models, T3 is connected to a fixed 5KΩ resistor.
- T5 Discharge Temperature Sensor (UUC136WC/UUC148WC Only):** Troubleshooting involves checking sensor-PCB connection and sensor status (open/closed). T5 resistance at 77°F (25°C) is 50KΩ, and at 95°F (35°C) is 33KΩ.
- Low Pressure Error (UUC148WC Only):* Troubleshooting involves checking for lack of refrigerant, repairing leaks, charging refrigerant, and checking/replacing the PCB or low-pressure switch. CN17 is the low pressure switch connection.
- High Pressure Error: Troubleshooting involves checking for excessive refrigerant, recovering/recharging refrigerant, checking the outdoor unit coil, and checking/replacing the PCB or high-pressure switch. CN13 is the high pressure switch connection.
- Fan Motor Error: Steps include checking DC fan motor wiring, fan driver board for damage, and the CN8 port of the main PCB. Provides details on checking voltage at CN8 pins (1-2: 310V DC, 3-2: 15V DC, 4-2: 0-5V DC, 5-2: 0-5V DC). Fan motor rated voltage is 310VDC, power output 220W, and rated speed 870 RPM.
Error Codes (UUC136WC/UUC148WC Only):** The manual lists LED flash patterns on the outdoor unit PCB to indicate specific errors:
- Green LED on: Normal Operation
- 1 flash every 5s: High Pressure Error (resets after power cycle if occurs 3 times in 20 mins)
- 2 flashes every 5s: T3 (Outdoor Unit Heat Exchanger Sensor) Temperature Sensor Error
- 3 flashes every 5s: Over Current Error (Reserved for 36/48K models)
- 4 flashes every 5s: Power Phase Error (Only for three-phase models)
- 5 flashes every 5s: T5 (Compressor Discharge Temperature Sensor) Temperature Sensor Error
- 6 flashes every 5s: Low Pressure Error (48K model only, resets after power cycle if occurs 3 times in 20 mins)
