Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by eliminating any risk of electric shock.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.

How to troubleshoot the AC unit

Find out what’s causing the F1 error on your GE unit and how you can clear it by following these steps.

1. Disconnect the appliance from the power source.
2. Remove the air filter from the front of the unit by pulling it out.
3. Lift up the front cover from the lower corners and pull it straight out to remove it from the clips.
4. After removing the front cover, find the indoor fan motor. It’s secured in place with a bracket and two screws.
5. Check the fan blade and motor for any debris or obstructions that would prevent it from rotating. Clean the area if needed.
6. Check for any loose wiring connections to the motor. Reseat them if needed. If the wiring is damaged, replace it.
7. Set a multimeter to resistance mode (Ω).
8. Use the meter probes to test the wiring between the main control wires at connection J2 pin 1 and pin 2 (blue to yellow). You should get a reading of approximately infinity (∞) Ohms.
9. Use the meter probes to test the wiring between pin 3 and pin 4 (white to black). You should get a reading of approximately 38.5k Ohms.
10. Use the meter probes to test the wiring between pin 3 through pin 6 (white to red). You should get a reading of approximately infinity (∞) Ohms.
11. Use the meter probes to test the wiring between pins 4 through 6 (black to red). You should get a reading of approximately infinity (∞) Ohms.

If the fan motor is damaged or you get resistance readings outside the acceptable range, replace the fan motor.
