Where Is The Reset Button On A Goodman Ac Unit

Modern air conditioning systems are complex electromechanical devices. When an AC unit malfunctions, it can be frustrating and uncomfortable, especially during hot weather. While a professional HVAC technician is often required for complex repairs, a simple reset can sometimes resolve minor issues. This article focuses on locating the reset button on a Goodman AC unit, a popular brand known for its reliability and efficiency.
Understanding the Need for a Reset
Before diving into the location of the reset button, it's crucial to understand why a reset might be necessary. An AC unit may require a reset for several reasons, including:
- Power Surges: Fluctuations in the electrical supply can sometimes trigger safety mechanisms within the unit, causing it to shut down.
- Overheating: If the compressor or other components overheat, a safety switch may activate, requiring a reset to restore operation.
- Frozen Coils: Ice buildup on the evaporator coils can restrict airflow and cause the system to malfunction. A reset may be needed after the ice has thawed.
- Control Board Issues: Minor glitches in the control board's programming can sometimes be resolved with a reset.
- Safety Lockouts: Some units are programmed to shut down and require a manual reset after detecting a specific number of errors or faults.
However, it's important to note that a reset is only a temporary solution. If the problem persists after resetting the unit, it indicates a more serious underlying issue that requires professional attention. Repeatedly resetting an AC unit without addressing the root cause can potentially damage the system.

Locating the Reset Button: Outdoor Unit (Condenser)
The primary reset location to check on a Goodman AC unit is typically within the outdoor condenser unit. This is the large metal box located outside your home that houses the compressor, condenser coil, and fan. The reset button is often associated with the compressor's overload protector.
Steps to Locate the Reset Button on the Outdoor Unit:
- Safety First: Before working on any electrical equipment, always disconnect the power supply to the AC unit. Locate the disconnect switch, usually a metal box mounted on the wall near the condenser unit. Flip the switch to the "OFF" position. This will prevent electrical shock. If you are uncomfortable working with electrical components, contact a qualified electrician or HVAC technician.
- Access the Control Panel: The reset button is usually located inside the control panel of the condenser unit. This panel is typically a metal cover that can be removed by unscrewing a few screws. The screws are often located on the side or front of the unit.
- Identify the Compressor: Once the control panel is open, locate the compressor. It's a large, black, cylindrical component, usually located at the bottom of the unit.
- Locate the Overload Protector: The overload protector is a small, often circular or rectangular device attached to the compressor. It's designed to protect the compressor from overheating. The reset button is usually located on or near the overload protector. It may be a small, red or black button, sometimes labeled "RESET".
- Press the Reset Button: If you find the reset button, press it firmly. You might hear a click, indicating that the overload protector has been reset.
- Reassemble and Restore Power: Carefully reattach the control panel and tighten the screws. Return to the disconnect switch and flip it to the "ON" position to restore power to the AC unit.
- Monitor the Unit: Observe the AC unit to see if it starts and runs properly. If the unit still fails to operate or trips again soon after being reset, it indicates a more serious problem requiring professional service.
Important Note: Some Goodman AC units may not have an easily accessible external reset button on the compressor overload protector. In these cases, the overload protector may reset automatically after a certain period of time, or the unit may require a more sophisticated diagnostic and reset procedure by a qualified technician.

Checking the Indoor Unit (Air Handler)
While less common, some Goodman AC units may have a reset function associated with the indoor unit, also known as the air handler. This unit is typically located in an attic, basement, or closet and contains the evaporator coil and blower fan.
Steps to Check the Indoor Unit:
- Safety First (Again!): Before inspecting the indoor unit, disconnect the power supply to the entire AC system at the main breaker panel in your home. This will ensure your safety.
- Locate the Control Panel: Similar to the outdoor unit, the indoor unit has a control panel that houses the electrical components. Remove the panel cover by unscrewing the screws.
- Inspect the Control Board: Look for a control board within the panel. This board is a printed circuit board with various electronic components. Some advanced control boards may have a small reset button, sometimes labeled "RESET" or "FAULT RESET".
- Consult the Manual: If you find a reset button on the control board, consult the unit's owner's manual to understand its specific function and proper reset procedure. Incorrectly pressing a reset button can potentially damage the control board.
- Look for a Float Switch: In some installations, a float switch is used to detect water buildup in the condensate drain pan. If the pan overflows, the float switch will shut down the AC unit. Once the water is drained, the float switch may need to be manually reset. This switch is typically located near the condensate drain pan and may have a small reset button.
- Reassemble and Restore Power: After inspecting the indoor unit, carefully reattach the control panel cover and restore power to the AC system at the main breaker panel.
Important Note: Indoor unit resets are less common and often involve safety devices like float switches. If you are unsure about the location or function of any reset button within the indoor unit, consult the owner's manual or contact a qualified HVAC technician.

When to Call a Professional
While a simple reset can sometimes resolve minor AC unit issues, it's essential to recognize when professional help is required. Consider contacting a qualified HVAC technician in the following situations:
- Repeated Resets: If the AC unit requires frequent resets, it indicates a persistent underlying problem.
- Unusual Noises: Strange sounds emanating from the unit, such as banging, hissing, or grinding, may indicate mechanical or compressor issues.
- Reduced Cooling Performance: If the AC unit is not cooling effectively despite running continuously, there may be refrigerant leaks, compressor problems, or airflow restrictions.
- Electrical Issues: If you detect any electrical problems, such as burning smells or sparking, immediately shut off the power to the unit and call a qualified electrician or HVAC technician.
- Lack of Knowledge: If you are uncomfortable working with electrical components or lack the necessary knowledge to troubleshoot the AC unit, it's always best to seek professional assistance.
Attempting to repair complex AC unit problems without proper training and experience can be dangerous and may further damage the system. It's always wise to err on the side of caution and entrust repairs to qualified professionals.

Preventive Maintenance
Regular preventive maintenance can help minimize the need for resets and extend the lifespan of your Goodman AC unit. Some essential maintenance tasks include:
- Regularly Clean or Replace Air Filters: Dirty air filters restrict airflow, causing the AC unit to work harder and potentially overheat.
