Reset Button On AC Unit Outside Goodman: Complete Guide for Homeowners

If your Goodman air conditioning system has stopped functioning, locating and using the reset button on AC unit outside (Goodman) could be the fastest solution. This article provides step-by-step guidance on finding, using, and troubleshooting the reset button on a Goodman outdoor AC unit. Homeowners will learn about when and how to reset the system, important safety tips, and common reasons for AC malfunctions.

What Is the Reset Button On a Goodman AC Unit?

The reset button on a Goodman AC unit is a safety feature designed to protect the system during abnormal operating conditions. Its primary role is to interrupt the circuit to prevent damage from surges, overheating, or faults. Pressing the reset button restores the system to standard operating mode after an issue has been resolved.

Where Is the Reset Button Located On a Goodman Outdoor AC Unit?

Unlike some brands, a Goodman outdoor AC unit may not always feature a clearly labeled reset button. The reset function is often integrated within the system’s high-pressure switch or near the electrical control panel. Typically, you can find the button or reset mechanism:

• On or near the outdoor unit’s access panel
• Close to wiring connections or contactor relay
• Behind a removable metal or plastic cover

Always turn off power at the breaker before inspecting your outdoor unit to avoid electrical hazards.

Goodman AC Reset Situations

Homeowners may seek the Goodman AC reset button for various reasons, including:

• AC not turning on after a power outage
• The compressor isn’t running, but fans operate
• Frequent tripping of the system’s breaker
• After addressing errors, faults, or maintenance needs

Identifying the cause is essential before performing a reset to avoid further damage.

How to Safely Reset a Goodman AC Unit

Step-by-Step Instructions for Most Models

1. Turn off the Thermostat

   Switch the thermostat to “OFF” to prevent accidental cycling.

2. Disconnect the Power

   Shut off power at the main breaker, or pull the disconnect near the outdoor unit. This step is crucial for safety.

3. Remove The Access Panel

   With a screwdriver, carefully remove the access panel or cover on the AC’s outdoor unit. Look for a small red or black button, typically close to the control board or behind wiring.

4. Locate and Press the Reset Button

   If present, firmly press the reset button. Hold for around 3-5 seconds, then release.

5. Restore Power and Test Operation

   Reattach the panel, restore power from the breaker, and turn the thermostat back to the “COOL” setting. Observe the unit for normal function.

If There’s No Physical Reset Button

If you don’t see a reset button, many Goodman models require a “manual reset” by shutting power off for 1–5 minutes, then turning it back on. This allows system logic and circuit boards to reset internally.

Common Problems Solved by Resetting the Outdoor Unit

Problem	How Resetting Helps
No Power After Surge	Resets protection circuitry and resumes normal function
Compressor Won’t Run	Allows compressor to restart if high-pressure switch was triggered
Frequent Tripping	Clears minor faults, but persistent tripping signals deeper issues
Control Board Errors	Resets microprocessor logic and sensors for accurate operation

Why Does My Goodman AC Need Resetting?

Several conditions trigger the system’s protection circuitry or cause a forced shutdown:

• Power Surges or Outages: Sudden changes can scramble the control board.
• Overheating: Blocked coils or fan issues trigger the high-pressure switch.
• Faulty Thermostat: Error signals prevent startup until reset.
• Compressor Lockout: Prolonged cycling or overloads require a reset for restart.

Resetting temporarily solves these, but persistent problems indicate deeper system faults that require professional attention.

Troubleshooting: What If My Goodman AC Won’t Reset?

1. Check the Power Supply:

Ensure the circuit breaker is ON and the disconnect is fully engaged at the outdoor unit. Bad breakers or loose wiring can prevent operation even after pressing “reset.”

2. Examine the Thermostat:

Sometimes a faulty thermostat, dead batteries, or incorrect settings prevent the AC from running after a reset. Try replacing batteries or confirming the system is set correctly.

3. High-Pressure Switch Lockout:

Most Goodman outdoor units have a high-pressure switch (sometimes with a reset push button). If the unit overheats or flow is restricted, this must be cleared before a reset will work.

4. Blown Fuses or Damaged Wiring:

Internal system fuses or burnt wires can disrupt power flow. Inspect for visible damage or blown fuse links on the control board. Replace as needed or contact a licensed HVAC technician.

5. Persistent Fault Codes:

Many recent Goodman models display fault codes on a small board or through thermostat diagnostics. If errors persist after resetting, call a Goodman-certified technician.

How to Find a Goodman AC Reset Button Diagram or Location Guide

Goodman service manuals or model-specific guides often detail the reset button location or “manual reset” methods. Access these documents through:

• Goodman Manufacturer’s Website
• HVAC contractor websites with model lookups
• User forums and support communities

Always use the full model number (e.g., GSX13, GSX16, etc.) when searching for diagrams.

Maintaining Your Goodman AC Unit for Fewer Resets

• Change air filters regularly – dirty filters reduce performance and cause unnecessary shutdowns.
• Clear debris around the outdoor unit to prevent overheating or airflow blockages.
• Inspect electrical connections annually or after severe weather.
• Schedule annual professional maintenance for cleaning, checks, and system tune-ups.

Routine care reduces the need for manual resets and prolongs equipment life.

When to Call a Professional HVAC Technician

While using the reset button on your outside Goodman AC unit is simple for minor issues, persistent problems require professional servicing:

• AC immediately trips breaker after reset
• Physical damage, burnt wire odor, or water near the unit
• Repeated compressor or high-pressure faults
• No response even after successful reset procedure

Never attempt advanced repairs beyond pressing the reset button or disconnecting power unless you are a licensed professional.

Goodman AC Models and Reset Button Locations

Model Series	Typical Reset Mechanism	Common Location
GSX13, GSX16, GSX18	High-pressure switch with button	Near compressor terminals or inside panel
GSC13, DSXC16, DSXC18	Circuit board reset or power cycle	Behind control board cover
Older Goodman Models	Breaker reset only	No physical button; power off/on via disconnect

Frequently Asked Questions About Goodman AC Reset Buttons

Does Every Goodman Outdoor AC Unit Have a Reset Button?

Not all Goodman AC models have a physical reset button outside. Newer models often require a manual reset by power cycling, while select models offer a high-pressure switch reset button (usually red or black) behind an access panel or near the compressor.

How Often Should I Need to Reset My AC Unit?

Occasional resets after power surges or extreme weather are normal. However, needing to reset your AC frequently likely means an underlying issue such as dirty coils, poor airflow, or electrical failure. If this happens more than once per season, schedule an HVAC inspection.

Can Resetting an AC Unit Fix All Problems?

Resetting the outdoor unit can resolve minor, temporary faults but won’t fix lasting mechanical or electrical problems. Resetting repeatedly without addressing the root cause can lead to more severe damage or breakdowns.

Reset Button Safety Tips

• Always shut off circuit breaker power before opening the outdoor unit
• Only press the reset button with dry hands and insulated tools if needed
• If you see sparks, smoke, or hear unusual noises, do not attempt further resets—call a professional
• After resetting, monitor the system closely for several minutes to ensure proper operation

Goodman AC Not Cooling Even After Resetting? Top Causes

1. Low Refrigerant Levels

   Insufficient refrigerant due to leaks prevents proper cooling, making resets ineffective.

2. Dirty Coils or Clogged Filters

   Reduces airflow and efficiency, leading to overheating and system shutdowns.

3. Faulty Capacitors or Relays

   These components may fail and prevent the compressor or fans from starting, even after resets.

4. Thermostat Misconfiguration

   Incorrect settings or bad thermostats keep the system off after a reset.
