What’s Wrong With Your Goodman Air Conditioner?
Remember to turn your A/C completely off before opening it up to look around or attempt any fix.
Does your air conditioner have too little air flow?
Airflow problems are usually because of a dirty filter, so clean the filter and see if that increases the circulation.
Are there bad smells throughout the house?
Bad smells, such as cooking odours, typically mean the filter is dirty and needs to be cleaned or replaced.
Is there not enough cold air?
This could be because the unit isn’t large enough for the space you’re trying to cool, the thermostat setting is wrong, the refrigerant is low, poor airflow, or there’s moisture in the system.
Is the unit blowing hot air?
The likely cause here is a refrigerant leak. Other signs that this is the case include ice on the refrigerant line, fluctuating temperatures, and bubbling noises.
Are there leaks?
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.
Is the compressor not running?
Plenty of things can cause compressor failures, such as defective capacitors, worn contactors, control board malfunctions, improper refrigerant levels, voltage levels, and wiring problems.
Is the system not running at all?
This is often an electrical issue, including that the unit isn’t getting power because the circuit breaker tripped, a fuse blew, connections are loose, or even the wiring is faulty. Other possible causes include a control board defect, improper thermostat settings, and high- or low-pressure problems.
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|
