How to Replace Your Goodman Air Filter
Every air conditioner is equipped with an air filter that eliminates pollutants, dust, and other contaminants from the air. To keep your indoor air quality high and ensure your air conditioner functions efficiently, it’s important to keep the filter clean by changing it every one to three months during the cooling season. The following steps will walk you through the process of changing the filter:
- Turn off power to the unit to prevent shocks and excess dust
- Locate the filter, either in the return air duct or on the indoor unit
- Remove the grille or access panel
- Slide out the old filter
- Clean the old filter with water and mild soap, or replace it with a new one
- When putting the filter in, use the arrows as a directional guide
- Replace the grille or access panel
- Turn the unit back on

Common Air Conditioner Problems and Troubleshooting
Remember to turn your A/C completely off before opening it up to look around or attempt any fix.
When there’s a clog in the drain line, it will result in the drain pan filling up and overflowing. It’s important to unclog the drain line because the water can damage other components.
Goodman Air Conditioner Error Codes
Your Goodman air conditioner is equipped with LED lights that flash different colours and in different sequences to indicate operational status. For example, when the green light is on, it means the unit is getting power and operating normally. However, the LED can also flash yellow or red to indicate error codes, and point you in the direction of what’s wrong with the unit. Here’s what those different error flash codes mean:
|Goodman Error Code||What this means|
|Red light on||There's been a call for cold air, but the compressor isn't running|
|One yellow flash||Compressor cycles are too long|
|Two yellow flashes||High-pressure problem|
|Three yellow flashes||Compressor cycles are too short|
|Four yellow flashes||Rotor is locked, possibly because of a failed capacitor|
|Five, six, seven, or nine yellow flashes||Problem with the circuits or voltage|
|Eight yellow flashes||Compressor is always running|
