Ge Window Ac Compressor Not Turning On

Introduction

A window air conditioner is a lifesaver during hot weather. However, it can be extremely frustrating when your GE window AC unit stops cooling because the compressor isn’t turning on. The compressor is the heart of your AC, responsible for circulating refrigerant, which is essential for cooling. If it’s not working, you’re just blowing air. This issue can quickly make your home uncomfortable and can be especially problematic for those sensitive to heat. Let’s explore potential causes and solutions to get your AC running again.

Common Causes of GE Window AC Compressor Not Turning On

Here are some common reasons why the compressor on your GE window AC might not be starting:

Power Supply Issues: The AC isn’t getting enough electricity.
Overload Protection: The unit has overheated and the overload protector tripped.
Dirty Air Filter: A clogged filter restricts airflow, causing the unit to work harder and potentially overheat.
Frozen Evaporator Coils: Ice buildup can prevent the compressor from starting.
Faulty Capacitor: The capacitor helps start the compressor motor, and it might be failing.
Defective Compressor Motor: The motor itself could be damaged.
Thermostat Malfunction: The thermostat might not be signaling the compressor to turn on.
Wiring Problems: Loose or damaged wires can interrupt the power supply to the compressor.
Refrigerant Leak: Low refrigerant levels can prevent the compressor from engaging.

Symptoms Checklist

These indicators can help you identify if the compressor is the problem:

The AC unit turns on, but only blows warm air.
You hear a humming sound, but the air isn’t cooling.
The AC unit cycles on and off frequently.
The overload protection light is on (if your unit has one).
The fan works, but there’s no noticeable change in air temperature.

How to Fix GE Window AC Compressor Not Turning On Step-by-Step Guide

Follow these steps to troubleshoot your GE window AC:

Check the Power Cord: Make sure the AC is properly plugged into a working outlet. Test the outlet with another device to ensure it’s providing power.
Inspect the Circuit Breaker: Check your home’s circuit breaker panel to see if the breaker for the AC unit has tripped. If it has, reset it.
Clean the Air Filter: Remove the air filter and clean it thoroughly with soap and water. Allow it to dry completely before replacing it. A dirty filter restricts airflow and can cause overheating.
Check for Ice Buildup: Turn off the AC and unplug it. Let it sit for several hours to allow any ice buildup on the evaporator coils to melt. Ensure proper airflow is restored by cleaning the filter before restarting.
Reset the Overload Protector: Some AC units have an overload protector button. If yours does, unplug the unit, locate the button (usually on the back), and press it. Then, plug the unit back in and try turning it on.
Inspect the Capacitor (Advanced): This step involves opening the AC unit. If you’re not comfortable doing so, seek professional help. With the unit unplugged, carefully discharge the capacitor using an insulated screwdriver. Visually inspect the capacitor for bulging or leaking. If it looks damaged, it may need replacing.
Listen for Humming: If you hear a humming sound but the compressor isn’t starting, the start capacitor might be weak. Replacing the capacitor might solve the problem, but this usually requires professional assistance.
Check the Thermostat: Make sure the thermostat is set to a cool temperature and that it’s properly set to “cool” mode. Sometimes a simple setting adjustment can fix the issue.
Inspect Wiring (Advanced): With the unit unplugged, visually inspect the wiring inside the AC unit for any loose or damaged connections. If you find any, carefully reconnect or repair them. Be extremely careful when working with electrical components.
Ensure Adequate Ventilation: Make sure the back of the AC unit has adequate space for ventilation. Obstructions can cause the unit to overheat.
Wait and Retry: Sometimes, the compressor has simply stalled. Turn the unit off, unplug it for 30 minutes, and then plug it back in and try again.

Fix the Issue Without Buying Parts

Before considering replacements, try these free methods:

Reset: Unplug the AC for at least 30 minutes to reset the internal components.
Cleaning: Thoroughly clean the air filter and the exterior of the unit.
Recalibration (Thermostat): Double-check and recalibrate the thermostat settings.
Inspection Tips: Visually inspect for any obvious damage or obstructions.
Maintenance Basics: Regularly clean the air filter and ensure proper ventilation to prevent future problems.

When Replacement Might Be Necessary

If none of the troubleshooting steps work, the compressor itself or the control board might be faulty. Replacing these parts can be costly and often requires a professional.Consider replacement if the unit is older than 8-10 years. A new window AC unit typically costs between $150 and $500 USD, depending on size and features. Commonly failing parts include the compressor, capacitor, and control board.

Safety Warning

Always unplug the AC unit before performing any maintenance or repairs.
Avoid working on the AC unit with wet hands or on a wet floor.
If you’re not comfortable working with electrical components, seek professional help.
Discharge capacitors before touching them to avoid electric shock.

Tools You May Need

Screwdriver (Phillips and flathead)
Pliers
Wire stripper/cutter (for wiring repairs, optional)
Multimeter (for testing electrical components, optional)
Insulated gloves (optional, for added safety)
Shop Vacuum (for cleaning)

FAQ

Here are some frequently asked questions:

Q: Why is my AC blowing warm air even though it’s turned on?
A: The compressor may not be working, often due to a faulty capacitor, overload protection, or a refrigerant leak.
Q: How do I know if the capacitor is bad?
A: Visually inspect the capacitor for bulging or leaking. If it looks damaged, it’s likely bad. However, proper testing requires a multimeter.
Q: Can a dirty air filter cause the compressor to fail?
A: Yes, a dirty air filter restricts airflow, causing the unit to overheat and potentially damage the compressor.
Q: Is it worth repairing an old window AC unit?
A: If the repair cost is more than half the price of a new unit, it’s often better to replace it.

Conclusion

Troubleshooting a GE window AC unit with a compressor that won’t turn on can be a daunting task, but by following these steps, you can potentially fix the issue yourself. Start with the simple solutions, like checking the power and cleaning the filter. If the problem persists, it might be time to consult a professional. Don’t give up hope a little troubleshooting can often save you the cost of a brand new AC unit!
