Many American homeowners rely on Goodman air conditioning systems for dependable cooling, but even reliable units sometimes need a reset. The Goodman AC unit reset button serves as a simple troubleshooting tool for a variety of common issues. This article explores what the reset button does, how to find and use it, common scenarios for pressing it, and what to do if your Goodman AC continues having problems after a reset. Whether you’re an experienced DIYer or a new homeowner, understanding this feature can save you time and money while keeping your home comfortable.
What Is The Goodman AC Unit Reset Button?
The reset button on a Goodman AC unit is a safety and diagnostic feature designed to restore the system to its default settings following a fault or power interruption. When triggered, this button interrupts the circuit, often cutting power to the compressor to prevent damage. Pressing it can resolve issues such as tripped breakers, power surges, or certain electronic errors without professional intervention.
Where To Find The Reset Button On A Goodman Air Conditioner
On most Goodman central air conditioning units, the reset button is located on the outdoor condenser unit. Look for a small, red or black button—usually labeled “RESET”—which is often situated near the refrigerant lines, control panel, or where the wiring enters the cabinet. On some models, it might be concealed behind a removable service panel requiring a screwdriver to access. Refer to your unit’s owner’s manual for an exact location.
| Goodman AC Model | Typical Reset Button Location | Button Color |
|---|---|---|
| GSX13, GSX14 Series | Control panel (outdoor unit) | Red |
| GSXC18, DSXC16 Series | Near service valve connections | Black |
| GSC13 Series (older) | Behind side access panel | Black or Red |
When Should You Use The Goodman AC Reset Button?
Homeowners should consider pressing the reset button if their AC is not turning on, the compressor fails to engage, or after a power outage or surge. It is also helpful after addressing a tripped circuit breaker, or if the thermostat displays an error. However, repeated use indicates an underlying issue that may require professional attention.
Step-By-Step Guide: How To Reset Your Goodman AC Unit
Safety Preparation
Ensure your safety first: Turn off the thermostat and disconnect power to the Goodman unit at the breaker. This step prevents electrical hazards and protects the equipment from short cycling or power surges.
Locating The Reset Button
- Go outside to the condenser unit.
- Locate the service panel or control panel (use a screwdriver if required).
- Find the reset button—typically a small, colored button, sometimes labeled as “RESET.”
Resetting The Unit
- Press the reset button firmly for 3-5 seconds.
- Some models require you to hold until you feel or hear a click.
Restoring Power And Testing
- Reconnect power at the breaker and turn the thermostat back on.
- Set the thermostat to COOL and wait a few minutes for the system to start.
- Check if the system operates correctly; cool air should begin circulating within 5-10 minutes.
Common Problems The Reset Button Can Solve
While the reset button is not a fix-all, it resolves several frequent Goodman AC issues:
- Power Interruptions: Restores function after electrical storms or brownouts.
- Thermostat Communication Errors: Fixes problems after replacing the thermostat or power cycling the control board.
- Compressor Lock-out: Releases the compressor if it has switched into lockout mode.
- Minor Electronic Glitches: Clears faults such as flashing LED error codes on the control board.
When The Reset Button Won’t Work: Next Steps
If the Goodman AC reset button does not resolve the issue, further troubleshooting is required. Persistent problems suggest deeper faults—such as faulty capacitors, blown fuses, a burned compressor relay, low refrigerant, or thermostat issues. Avoid pressing the button repeatedly, as this may exacerbate system strains or further damage components.
Recommended Troubleshooting Steps
| Potential Cause | What To Check | Possible Solution |
|---|---|---|
| Tripped Breaker | Electrical panel/breaker box | Reset breaker, ensure proper wire connections |
| Dirty Air Filter | Inspect air filter in return vent | Clean or replace air filter |
| Thermostat Fault | Check settings and battery | Replace or recalibrate thermostat |
| Blown Fuse | Service disconnect panel near condenser | Replace cartridge fuse |
| Coil Freezing | Look for ice on evaporator/condenser coils | Turn off system, allow to thaw, check airflow |
Reset Button FAQs: Answers To Common Goodman AC Questions
Is Every Goodman AC Equipped With A Reset Button?
Most Goodman AC units manufactured after 2010 include a reset button, though older or budget models may not. For those units, resetting power manually at the circuit breaker is an alternative. Always consult your user manual or unit labeling to confirm.
How Often Can The Reset Button Be Used?
The reset button should not be overused. Press it to resolve occasional issues, but frequent resets suggest a chronic problem needing professional diagnosis—calling a certified HVAC technician is recommended.

Will Resetting My Goodman Air Conditioner Erase My Thermostat Settings?
No, using the reset button on your AC does not alter thermostat schedules or settings. If a smart thermostat is used, settings are usually retained unless the thermostat itself is reset, powered down, or replaced.
The Role Of The Reset Button In Routine Goodman AC Maintenance
The reset button is not just for emergencies—it can also play a role after routine maintenance or repairs. Whenever electrical connections, controls, or boards are serviced, pressing the reset button ensures the system reboots safely and error-free.
Safety Tips: Cautions When Using The Goodman AC Reset Button
- Never attempt to reset the AC while power is on.
- Wear insulated gloves if opening panels near electrical connections.
- Do not force the button; if it does not click or respond, seek professional help.
- Never bypass or jump wires to simulate a reset. Misuse may void warranties or create fire hazards.
Goodman AC Troubleshooting Flowchart
The steps below can serve as a flowchart when diagnosing an unresponsive Goodman AC system:
- Check the thermostat. Is it powered and set to COOL?
- Is the breaker tripped? If so, reset it once only.
- Is the air filter clean?
- Are the outdoor disconnect and indoor access panel secure?
- Press the reset button as described above.
- If problems persist, call a licensed HVAC technician for deeper inspection.
What Causes A Goodman AC To Need Resetting?
The need for a reset typically arises due to electrical anomalies, component faults, or safety trips. Common triggers include:
- Voltage fluctuations and power surges from nearby lightning strikes or electrical grid issues
- Compressor overheating during peak demand
- Incorrect installation or loose control board wiring
- Recent maintenance requiring power disconnection
Reset Button And Goodman Warranty Considerations
Using the reset button properly does not void your Goodman AC warranty. However, attempting unauthorized repairs, opening sealed compressor units, or modifying wiring may invalidate coverage. Pause after a reset to check if the system operates normally; document problems for warranty claims if necessary.
What To Expect When A Goodman AC Is Successfully Reset
After pressing the reset button and restoring power:
- The outdoor unit (condenser fan) should begin running within a few minutes.
- The indoor blower may start after a programmed delay.
- Check for cool airflow at supply vents. Listen for compressor engagement and absence of error codes or warning lights on the control board.
When To Call An HVAC Technician Instead Of Using The Reset Button
If the unit still displays warning lights, makes strange noises, stays off, or keeps tripping the reset button, it is time to call a qualified Goodman service professional. Persistent electrical faults, burnt odors, or physical damage are signals that require expert diagnosis and repair.
Tips For Preventing Future Goodman AC Errors
- Consider installing a surge protector for the AC unit to guard against lightning and power surges.
- Keep outdoor coils free of debris, leaves, and lawn clippings.
- Schedule annual cleaning and inspection with an HVAC technician.
- Change air filters every 1-3 months for optimal airflow and system health.
Why Goodman AC Reset Button Knowledge Matters For Homeowners
Understanding the role and location of the Goodman AC reset button makes maintenance easier and more efficient. Quick response to minor outages and power disturbances helps avoid costly service calls and maximizes cooling performance throughout the hottest months.
