Goodman Air Conditioner Not Turning On

Introduction

Is your Goodman air conditioner refusing to turn on, leaving you sweltering in the heat? A malfunctioning AC unit can be a major inconvenience, especially during the hottest months. It’s important to address this issue quickly to prevent further damage and restore comfort to your home. This guide will walk you through troubleshooting steps to help you identify and potentially fix the problem yourself.

Common Causes of goodman air conditioner not turning on

Several factors can cause your Goodman air conditioner to fail to start. Here are some of the most common:. For more related activities, check out our Central Air Freezing Up.

• Tripped Circuit Breaker: An overloaded circuit can trip, cutting power to the AC unit.
• Thermostat Issues: An incorrectly set or malfunctioning thermostat won’t signal the AC to turn on.
• Dirty Air Filter: A clogged filter restricts airflow, causing the unit to overheat and shut down.
• Power Cord Problems: A damaged or loose power cord can prevent the AC from receiving power.
• Condenser Fan Motor Failure: The fan helps cool the unit; if it fails, the system might not start.
• Capacitor Problems: Capacitors provide the initial surge of power to start the motor; a faulty capacitor can prevent starting.
• Refrigerant Leak: Low refrigerant levels can prevent the unit from cooling and eventually stop it from starting.
• Dirty Condenser Coils: Dirty coils reduce the unit’s ability to release heat, leading to overheating.
• Frozen Evaporator Coils: Restricted airflow can cause the evaporator coils to freeze, shutting down the system.
• Control Board Malfunction: The control board is the “brain” of the AC unit. If it malfunctions, the AC won’t start.

Symptoms Checklist

Observe the following to help narrow down the cause:

• The AC unit makes no noise at all when you turn it on.
• The thermostat display is blank or unresponsive.
• The outdoor unit (condenser) fan is not spinning.
• You hear a humming sound but the unit doesn’t start.
• The circuit breaker for the AC is tripped.
• Ice is visible on the copper lines or coils of the AC unit.
• The air coming from the vents is warm or not as cold as usual.

How to Fix goodman air conditioner not turning on Step-by-Step Guide

Follow these steps to troubleshoot your Goodman AC unit:

1. Check the Thermostat: Ensure the thermostat is set to “Cool” and the temperature is lower than the current room temperature. Make sure the batteries are fresh if it’s battery-powered.
2. Inspect the Circuit Breaker: Locate the circuit breaker for the AC unit in your electrical panel. If it’s tripped (switched to the “Off” position or in the middle), flip it all the way to the “Off” position, then back to the “On” position.
3. Check the Power Cord: Make sure the power cord is securely plugged into the outlet. Inspect the cord for any damage.
4. Replace the Air Filter: A dirty air filter restricts airflow. Replace it with a clean filter of the correct size.
5. Inspect the Outdoor Unit (Condenser): Check for any obstructions around the unit, such as leaves, debris, or overgrown plants. Clear any obstructions.
6. Clean the Condenser Coils: Use a garden hose (with a gentle spray nozzle) to rinse the condenser coils from the inside out. Be careful not to bend the fins.
7. Check for Frozen Evaporator Coils: If you suspect frozen coils, turn off the AC and switch the fan to “On” to help melt the ice. After a few hours, try turning the AC back on.
8. Inspect the Condenser Fan: Make sure the fan blades are clean and can spin freely. If the fan motor isn’t working, it might need professional attention.
9. Check the Condensate Drain Line: A clogged drain line can cause the unit to shut down. Locate the drain line (usually a PVC pipe) and clear any clogs. You can use a wet/dry vacuum to suck out the clog.
10. Listen for Unusual Noises: Listen closely to the unit when you attempt to turn it on. Unusual buzzing, clicking, or grinding noises can indicate a more serious problem.
11. Reset the AC Unit: Some AC units have a reset button. Consult your owner’s manual to locate it and press it to reset the unit.
12. Examine Capacitors: (Advanced – proceed with caution and disconnect power first). Locate the capacitor (usually a cylindrical component) inside the outdoor unit. Look for bulging or leaking, which indicates failure. Note: Capacitors store high voltage even after the unit is off. If you’re not comfortable working with electrical components, skip this step and call a professional.

Fix the Issue Without Buying Parts

Often, you can resolve the issue without purchasing new parts. Focus on these free methods:

• Regularly clean or replace the air filter to ensure proper airflow.
• Keep the area around the outdoor unit clear of debris and obstructions.
• Periodically clean the condenser coils with a gentle spray of water.
• Manually reset the circuit breaker if it trips frequently. This may require replacing the breaker if it continues to trip.
• Inspect the condensate drain line regularly for clogs.
• Follow your AC unit’s recommended maintenance schedule as outlined in the owner’s manual.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and your Goodman AC unit still isn’t turning on, it might be time to consider professional help or even replacement. Common parts that fail include the capacitor, condenser fan motor, compressor, or the control board. Replacing the entire unit can be expensive, ranging from $3,000 to $7,000 (USD) depending on the size and efficiency of the new unit. Repair costs can range from $200-$1000 depending on the part. Get several quotes from qualified technicians before making a decision.

Safety Warning

• Always disconnect power to the AC unit at the circuit breaker before performing any maintenance or repairs.
• Avoid working on electrical components if you’re not comfortable or experienced. Call a qualified technician.
• Never spray water directly onto electrical components.
• Be careful when using ladders to reach the outdoor unit.
• If you suspect a refrigerant leak, do not attempt to fix it yourself. Refrigerant is a hazardous substance, and handling it requires specialized equipment and training.

Tools You May Need

• Screwdriver (Phillips and flathead)
• Pliers
• Wrench set
• Multimeter (for testing electrical components – advanced)
• Garden hose with spray nozzle
• Wet/dry vacuum
• New air filter

FAQ

• Q: My AC unit is making a humming noise but not turning on. What could be the problem?A: This could indicate a problem with the capacitor or the compressor. Call a technician.
• Q: How often should I replace my air filter?A: Ideally, replace it every 1-3 months, or more frequently if you have pets or allergies.
• Q: Why is my AC unit tripping the circuit breaker?A: This could be due to an overloaded circuit, a faulty component in the AC unit, or a failing circuit breaker.
• Q: Can I clean the condenser coils myself?A: Yes, you can clean the condenser coils with a garden hose and a gentle spray nozzle. Be careful not to damage the fins.
• Q: What does SEER stand for?A: Seasonal Energy Efficiency Ratio. It is a measure of how efficient an air conditioner is. The higher the SEER rating, the more efficient the unit.

Conclusion

Troubleshooting your Goodman air conditioner can seem daunting, but by following these steps, you can often identify and resolve the issue yourself. Remember to prioritize safety and consult a qualified technician if you’re uncomfortable with any of the procedures. With a little effort, you can get your AC unit back up and running, restoring comfort to your home without breaking the bank. However, if the problem persists after these steps, calling a professional is your best bet.
