Common Goodman Error Codes

When your Goodman furnace begins to show signs of malfunction, understanding the error codes can be a critical first step in troubleshooting the issue. Here, you’ll find explanations for some of the most common Goodman furnace error codes. These diagnostic indicators can help you identify the problem and decide whether it’s a simple fix or if you need to contact a professional.

Error Code 101

Error Code 101 on your Goodman furnace typically indicates an issue with the furnace’s air intake. This code is often triggered by a dirty or clogged air filter. When the airflow is restricted, your furnace can’t operate efficiently, leading to potential overheating and a safety shutdown.

To address this error, check your furnace’s air filter and replace it if it’s dirty. Regularly changing your air filter can prevent this error from occurring in the future. If the error persists after replacing the filter, there may be other airflow obstructions or issues with the furnace’s internal components that require professional attention.

Error Code 202

The appearance of Error Code 202 signals a problem with the pressure switch circuitry. This could stem from a variety of issues, such as a malfunctioning pressure switch, blocked vent pipes, or a defective inducer motor. The pressure switch ensures that there’s proper airflow for combustion and venting, and if it fails to close or open correctly, the furnace will not operate safely.

Before you call for professional help, you can inspect the vent pipes for blockages and ensure they are properly connected. However, issues with the pressure switch or inducer motor often require technical expertise. You can refer to our goodman furnace error flash troubleshooting for more detailed guidance.

Error Code 303

Encountering Error Code 303 indicates that your Goodman furnace’s flame sensor is either dirty or faulty. The flame sensor’s role is to confirm that a flame is present when the gas valve is open. If it’s unable to detect a flame, it will shut down the furnace as a safety precaution to prevent unburned gas from filling your home.

Cleaning the flame sensor is a straightforward process that you might be comfortable doing yourself, and it can often resolve this issue. However, if the problem persists or you’re unsure about handling furnace components, it’s best to seek professional help.
