This troubleshooting guide covers common issues with GE window ACs and provides tips to diagnose and fix the problems. Proper troubleshooting can save you the hassle and expense of a service call.

We’ll look at problems like the AC not turning on, not cooling or heating properly, water leaking, strange noises, error codes, and more. You’ll learn how to troubleshoot each issue based on the most likely causes and solutions.

While some repairs may require hiring a professional, many can be done yourself with basic tools and a voltmeter. Catching and fixing minor issues quickly can also help prevent more significant breakdowns down the road.

Keep reading for step-by-step troubleshooting procedures for the most prevalent GE window air conditioner failures.

Common GE Window AC Problems and Solutions

When your GE window AC starts malfunctioning, there are some common issues that are likely the cause. Below we’ll explore the most typical problems and walk through troubleshooting procedures to diagnose and fix them.

Air Conditioner Not Turning On

If your GE air conditioner will not power on at all, there are several possible causes to check:

  • Power connection issues – Make sure the unit is securely plugged into the electrical outlet. Also check the circuit breaker and reset it if tripped. Verify the outlet is working by plugging in another appliance. Finally, check the fuse and replace it if blown.
  • Faulty power cord – Using a multimeter, test the power cord for continuity. If there is no continuity, the power cord is defective and needs replacement.
  • Control board failure – The control board directs power to the AC components. Reset the control board by unplugging the unit for 2-3 minutes. If the AC still doesn’t turn on, the control board likely needs to be replaced.
  • Bad thermostat – Use a multimeter to test the thermostat for continuity. No continuity means it’s defective and must be replaced.

If the AC won’t start after checking these areas, contact a technician for further troubleshooting.

Air Conditioner Not Cooling

If your GE AC is running but not cooling properly, several issues could be to blame:

  • Dirty air filter – Check the filter and clean it if dirty. Refer to your owner’s manual for instructions. A clogged filter restricts airflow.
  • Temperature setting – Make sure the temperature setting is appropriately lowered. The room may have already gotten too warm.
  • Refrigerant leak – Low refrigerant levels can reduce cooling capacity. Have a technician inspect for leaks and recharge the refrigerant.
  • Frozen coils – Dust or low airflow can cause the evaporator coils to freeze over. Set the AC to fan-only mode to thaw the ice, and clean the filter.
  • Fan failure – If the fan isn’t circulating air, the AC won’t cool effectively. Test the fan motor with a multimeter and replace it if defective.
  • Compressor failure – If the compressor isn’t running, cooling stops. Have a technician inspect the compressor and replace it if needed.

Air Conditioner Not Heating

For GE window ACs with heating mode, here are some common causes if the unit isn’t heating properly:

  • Improper setting – Make sure the unit is set to high heat. The temperature setting may also be too low.
  • Dirty filter – A clogged air filter restricts airflow and reduces heating efficiency. Check and clean the filter.
  • Airflow obstruction – Make sure there are no objects blocking the front of the unit that could limit airflow.
  • Open doors/windows – The heating ability will be diminished if cold air is entering the room. Close windows and doors.
  • Refrigerant leak – Low refrigerant levels affect the heat pump’s efficiency. Have a technician inspect for any leaks.
  • Fan failure – No airflow means heated air can’t circulate. Test the fan motor with a multimeter and replace it if defective.

If you’ve verified these areas and the unit still won’t heat properly, contact a technician for further assessment.

Water Leaking

A few issues can cause a GE window AC to leak water:

  • Clogged drain line – Check the drain line and clear any debris blocking water flow.
  • Dirty filter – A clogged filter can cause ice buildup and overflowing water. Clean the filter.
  • Improper installation – The unit should tilt slightly outward to drain properly. Have a technician re-install the AC if tilted incorrectly.

Take time to monitor your unit while operating to try and pinpoint the exact location of leaks. Catching the problem early is key to prevent extensive water damage.

Thermostat Issues

Problems with the thermostat can cause a variety of AC malfunctions. Here are some thermostat-related problems and solutions:

  • Poor thermostat location – If placed in direct sunlight or near a heat source, the thermostat may give inaccurate readings and cause the AC to cycle improperly. Reposition it away from heat influences.
  • Defective thermostat – Use a multimeter to check the thermostat for continuity. No continuity means it’s faulty and needs replacing.
  • Temperature sensitivity – Operating when outdoor temps are below 70°F or indoor temps below 64°F can disrupt thermostat functioning. Only use the AC when temps are in the proper range.
  • Loose wiring – Make sure all wires leading to the thermostat are securely connected. Loose wiring interrupts power flow.

If you’re unsure how to test and troubleshoot the thermostat, contact an HVAC technician for assistance. A malfunctioning thermostat should be repaired quickly.

Noisy Operation

Some noises may be normal, like the sound of internal parts moving or water dripping on the condenser coils. But unusual noises could signify problems:

  • Loose parts – Inspect the front grille, panels, and other exterior parts for looseness causing vibration and rattling noises. Tighten any loose screws or fittings.
  • Imbalanced fan blade – Fan blades that are warped or misaligned can create noise. Have a technician inspect the fan assembly for balance and alignment issues.
  • Improper installation – An AC that’s crooked or on unlevel ground will vibrate abnormally and make noise. The unit may need to be reinstalled properly.

Determine where the noise is coming from before taking action. Turn off the unit if any noises seem severe or you notice rattling inside the cabinet.

GE Error Codes

Some GE window ACs feature built-in diagnostics that display error codes to identify system failures. Here are some common GE AC error codes and what they indicate:

  • E1 – This code signals an issue with the electronic control board. Try resetting the AC, and if the code persists, the control board likely needs to be replaced.
  • E4 – This code indicates the internal condensate removal bucket is full and needs emptied. If emptying the bucket doesn’t clear the code, inspect the bucket’s float switch for damage.
  • 88 – Displaying when first powering on the unit is normal. But if it lasts more than 2 seconds, it typically signifies a power supply failure. Have an electrician inspect the electrical circuit.

Any error code that persists after resetting the unit will require a technician visit. Write down the full error code before calling for service. Your owner’s manual may also provide more details on the codes.


GE window air conditioners are generally reliable, but occasional issues can arise. Following proper troubleshooting procedures helps diagnose problems accurately so they can be repaired quickly.

The most common AC failures relate to power, electrical components, thermostat malfunctions, refrigerant leaks, frozen coils, airflow restrictions, installation mistakes, and noise.

Basic troubleshooting steps include:

  • Checking power connections
  • Testing parts like the thermostat or fan motor with a multimeter
  • Resetting the control board
  • Cleaning or replacing dirty filters
  • Clearing drain line clogs
  • Adjusting temperature and unit settings
  • Ensuring proper airflow around the unit
  • Listening closely to isolate unusual noises

For complex issues like refrigerant leaks, compressor failure, or persistent error codes, hire a professional HVAC technician for repair. Proper regular maintenance is also key to minimize major breakdowns.

Following this GE troubleshooting guide equips you to handle many window AC problems on your own. But don’t hesitate to call in a technician when needed. Catching issues early prevents more extensive unit damage.
