Air conditioning systems, especially those from trusted brands like Goodman, are vital for keeping our homes cool during the summer heat. However, even the most dependable units can encounter problems, with one of the most frustrating being when your Goodman air conditioner won’t turn on. The cause often lies within malfunctioning Goodman AC parts, ranging from simple power supply issues to more complex system failures. In this article, we’ll explore the common reasons behind this problem and provide expert solutions.
Common Reasons Why Your Goodman Air Conditioner Won’t Turn On & Expert Solutions
Here are the common reasons why your Goodman air conditioner might not turn on, along with expert solutions to help you troubleshoot and resolve the issue.
1.Thermostat Problems
If your Goodman AC is on but not cooling, then the issue might be with the thermostat. Sometimes the system does not turn on due to a faulty thermostat or wrong settings of the thermostat. At other times it may just be a flat battery or the wrong temperature control.
Expert Solution:
- Check the preferences: Make sure the temperature is set below room temperature and that the thermostat is in the “Cool” setting.
- Replace the Batteries: Check if your thermostat is powered, if it has batteries, replace them to make sure it is receiving power.
- Recalibrate or Reset the Thermostat: If the thermostat is not functioning correctly, try adjusting it or restarting it based on the user manual.
2.Dirty Air Filters
The first and simplest issue that can be fixed is a clogged air filter. Dirt and debris can build up over time and restrict air flow, which can lead to overheating or even the complete shutdown of the system.
Expert Solution:
- Inspect and Replace the Air Filter: Switch off the power of your AC, then, take off the air filter and clean it for dirt and other debris. If it is blocked, then it should be cleared or else it should be replaced with a new one. It is recommended to change the air filter every 1-3 months to maintain proper air circulation and functioning of the system.
3.Faulty Capacitor or Motor
The capacitor is another component that aids in the starting of the motor in your Goodman air conditioner. If the capacitor or motor is faulty, the system may not start at all.
Expert Solution:
- Listen for Clicking or Humming Sounds: The capacitor is most likely damaged if you hear a clicking sound when you try to power the device. A humming sound without any startup could be due to a motor problem.
- Check the Capacitor: If you are confident with electrical parts, then you can use a multimeter to test the capacitor. However, because electrical work is dangerous, it is advisable to consult a licensed HVAC technician to check and repair or replace a faulty capacitor or motor.
4.Refrigerant Leak
Cooling requires the use of refrigerant in the process. If your Goodman air conditioner is low on refrigerant because of a leakage, it will not function properly, and it may not even power on.
Expert Solution:
- Look for Signs of Leaks: If you see ice on the coils or hear a hissing sound near the refrigerant lines, it may be a sign of a refrigerant leak.
- Call a Professional: Since working with refrigerant is dangerous and requires certifications, it’s better to call an HVAC technician to identify and fix leaks and approximately recharge the refrigerant.
5.Condenser Coil Issues
Your Goodman air conditioner’s condenser coil is in charge of releasing the heat that has been absorbed by the inside air. If the coil is blocked by debris or dirty, it will lead to malfunction of the unit or it will not turn on.
Expert Solution:
- Inspect the Outdoor Unit: Make sure that there are no obstructions to the airflow around the condenser coil on the outside unit. Remove any debris you find.
- Clean the Coils: If the condenser coils are dirty, it is recommended to clean them with a coil cleaner or to contact a professional to clean them properly.
6.Frozen Evaporator Coils
Frozen evaporator coils are another possible culprit when your Goodman AC won’t turn on. If airflow is restricted, or if there’s an issue with refrigerant, ice can form on the coils, preventing the system from functioning properly.
Expert Solution:
- Turn Off the AC: If you suspect that your coils are frozen, turn off your air conditioner and let the ice melt.
- Inspect the Coils: After the system has thawed, check the evaporator coils for ice formation. If the coils are frozen, then it is advisable to check the airflow, air filter, and refrigerant to solve the problem.
- Speak with an Expert: If the ice is still there, it is best to have a professional check the cooling system for refrigerant leaks and other issues.
7.Blower Fan Problems
The blower fan is used to circulate the cool air in your house. If the blower fan is not working, the air conditioning system may not start or may not cool the house as required.
Expert Solution:
- Check the Fan: Check for any signs of wear and tear or anything that may be blocking the blades of the fan. If the blades look fine but the fan is not running, it may be a motor or electrical problem that only a mechanic can solve.
When a Goodman air conditioner doesn’t turn on, it can usually be fixed by following a few easy steps, but occasionally a professional’s help may be required. By performing routine maintenance and timely inspections, you may prevent most of these problems and ensure that your device operates as intended.If troubleshooting does not help, do not wait to call a licensed HVAC technician for professional repairs and get your home comfortable again as soon as possible.
