Where is the reset button on a goodman air conditioner

Your Goodman AC may flash codes if it detects a failure. Understanding the Goodman Air Conditioner Codes is the first step to fixing your AC. In this article, we’ll cover a few possible failures you may face at home, and discuss which codes you may see when your Goodman AC won’t work.

Troubleshooting Common Goodman AC Failures

Before getting too deep into troubleshooting your Goodman AC, check out these common failures:

Goodman AC Stops Working – Reset Your Goodman Air Conditioner

One of the most common problems with Goodman air conditioners is when they suddenly stop working. In most cases, this can be fixed by simply resetting the unit.

Here’s how to reset your Goodman Air Conditioner:

1. Turn off the power to the Goodman air conditioner at the breaker box.
2. Wait a few minutes and then turn the power back on.
3. Press and hold the “Reset” button on the Goodman air conditioner for about 20 seconds.
4. Release the button and wait for the Goodman AC unit to start up again.

Goodman Air Conditioner Not Cooling Properly

If your Goodman air conditioner is not cooling properly, check the following prior to calling for service:

1. Is your air filter dirty? A dirty air filter can obstruct airflow and cause your Goodman AC to not cool properly. Be sure to change your filter at least every six months.
2. Make sure that all of the doors and windows in your home are completely closed so cool air isn’t leaking out.
3. Check your ductwork. If your ducts are clogged with debris or overly dusty, your unit may not cool properly. You can clean your ducts on your own or hire a duct cleaning service to do the work for you.
4. Low or leaking refrigerant. If your Goodman AC is low or leaking refrigerant, it won’t cool properly. Check the system for leaks and recharge the refrigerant if necessary.

Common Complaints about a Goodman AC Not Working

“I hear a thumping noise when the unit is running.” This usually means that there is an obstruction or problem with the fan blade.

“A fan is running but the unit isn’t cooling properly.” This could be caused by a dirty air filter, Freon levels that are too high or low, or an obstruction in the condenser coils.

“The unit is running but it doesn’t feel cool.” There are several possibilities here, including dirty air filters, high Freon levels, or an obstruction in the condenser coils.

“The outside fan motor won’t turn on.” Check to make sure that there isn’t debris stuck around the motor shaft. Look for loose wiring or corrosion. If there is, that’s most likely your issue.

“The compressor won’t turn on.” This could be caused by low Freon levels, a broken start capacitor, or an electronic component failure.

How to Troubleshoot Goodman Status Light LED Error Codes

Goodman air conditioner LED Status Light error codes are usually 1 – 9 flashes on the indoor control board of a Goodman central air conditioning system. Here’s how to troubleshoot them:

Code 1 – Furnace ignition failure. The control board has detected that the furnace failed to ignite. This could be due to low voltage, high resistance, or dirty terminals on the furnace primary control.

Attempt to resolve the issue by resetting the power. Turn off the power for 30 seconds, and then restore power.

Code 2 – Two flashes indicate that the furnace is receiving low voltage or flame failure issues.

• Check all wiring connections, make sure there are no burnt or broken wires.
• Make sure the breaker has not been tripped (in cases of power outage).
• Check for gas supply issues.

Code 3 – Three flashes indicate a problem with the pressure switch.

• Check the pressure switch hose for crimping.
• Check for loose wires or improperly seated plugs.
• Check for blockage in the vent.
• Replace the failed pressure switch.

Code 4 – Four flashes indicate an issue with the temperature switch or the unit is over the temperature limit.

• Check for a plugged filter and/or secondary heat exchange.
• Check for issues in the ductwork or blockages in the flue.

Code 5 – Five flashes indicates that there is a flame present when no flame should be present. This may result in a safety issue, so leave your unit OFF and contact an HVAC professional right away. Issues may include:

• Leaky or stuck gas valve
• Defective flame sensor

Code 6 – Six flashes indicate a problem with the electrical wiring. It may be as simple as replacing a blown fuse. However, if there is an issue with the wiring, be sure to contact a professional.

Code 7 – Seven flashes indicate a problem with the gas valve and/or the unit is registering a low flame signal.

Code 8 – Eight flashes indicate an issue with the igniter circuit. Check the igniter and replace it if necessary. If the igniter is working properly, there may be an issue with the wiring.

Code 9 – Nine flashes indicate a high-stage pressure switch won’t close. Check for a blocked pressure switch hose.
