Troubleshooting Common Goodman Errors

When your Goodman furnace is not working as expected, the red LED lights on the unit can provide you with an error code that helps in diagnosing the issue. Each pattern of flashing lights corresponds to a different error message. Here’s how you can address the most common error flashes.

Three Flashing Lights

If your Goodman furnace is showing three flashing lights, this typically indicates that the pressure switch circuit is open, or the draft blower is functioning when it shouldn’t be. This could be due to a blockage in the pressure switch or a connection issue.

To resolve this, you may need a heating system tune-up from a professional. They will inspect the pressure switch for any obstructions or improper connections that might be causing the issue.
