‍

When things go awry, it’s often hard to know exactly what’s wrong. Reading a furnace error code and troubleshooting the problem can be challenging. However, with a little knowledge and patience, you’ll get your Goodman furnace up and running again in no time. Read on to learn more about diagnosing and fixing common Goodman furnace errors. When something goes wrong with your home heating system, there is usually an indicator light or set of lights that alert you to a problem. In many cases, these lights are codes that go beyond just alerting you to the issue at hand. They also tell you exactly why the problem has occurred so that you can correct it as efficiently as possible.

Error Code Basics

An error code is a code that is used by machines to indicate a problem by stopping or slowing down the entire system. You will also see that the codes are usually displayed on a screen or some other form of indicator. The codes are used in a variety of industries, including electrical, oil, and even healthcare. The error code is meant to help you identify the problem and correct it as quickly as possible so that the system can run as it was intended. When it comes to heating and cooling systems, the error codes are based on the number of times that the system has reset due to a problem. The system will continue to reset until the issue has been resolved. In some cases, the error code is a simple message that gives you an indication of the problem at hand. In other cases, though, it can be a complicated code that requires further investigation.

Service Struggle

In some cases, you’ll see an error code that reads “service struggle”. This is different from other error codes in that it’s not an indication that something is wrong with the furnace. Instead, it’s a sign that there is a problem with the power source for the furnace. The furnace is attempting to reset because it can’t get enough power to run properly. In some cases, this can be an indication that the circuit breaker needs to be reset. In other cases, it could be a sign that there is an issue with your electrical wiring. If you see this error code, it’s important to have the furnace inspected by a professional. You also need to have your wiring inspected to ensure that there isn’t an issue that goes beyond the furnace itself.

Error Code 16

When an error code 16 is displayed on your furnace, it’s an indication that the filters in the unit are clogged. The filter is the part of the furnace that catches the excess dirt and dust that would otherwise be blown into your home through the vents. When the filter gets clogged, it can prevent the furnace from running properly. As a result, it will display an error code 16. The solution is to clean the filter as soon as possible. If you don’t clean the filter, you’re putting yourself and your family at risk. If you fail to clean the filter and the error code stays on, you’ll need to call a professional to replace the filter. If you don’t replace the filter, the system will keep resetting until the filter is removed. In some cases, the system might reset over and over again until the filter is removed. This could be a safety precaution in case the filter is clogged with something that could spill out and cause a fire.

Error Code 19 and 20

Error code 19 is an indication that there is a problem with the pressure switch. This is the switch that operates the safety mechanism on the furnace, preventing the system from overheating. Error code 20 indicates a problem with the humidifier. The humidifier is the part of the furnace that adds water to the air to help control the humidity in your home. It’s important to clean the humidifier regularly to ensure that everything is operating as it should be. Any debris that builds up in the humidifier could cause the error codes to appear. If the error codes continue to appear, you’ll need to have the furnace inspected by a professional. They will be able to tell you exactly what the problem is and how to correct it.

Error Code 24 and 25

Error code 24 is triggered when there is a problem with the flame sensor. This sensor ensures that the burner is receiving the right amount of oxygen so that it can burn properly. The flame sensor is located in the burner assembly. In some cases, the error code could indicate a problem with the sensor. In other cases, it could indicate a problem with the wiring to the sensor. Error code 25 is triggered when the pressure differential switch isn’t working properly. This is the switch that determines when the furnace should run. If the switch isn’t working correctly, the furnace may not turn on when it should. This could be a safety hazard, so it’s important to correct the issue as soon as possible.

Error Code 31 and 32

Error code 31 is triggered when there is a problem with the carbon monoxide sensor. This sensor is an important piece of the furnace, as it keeps you and your family safe. If the carbon monoxide sensor is broken or isn’t working properly, it could give off false alarms. It could also fail to alert you to the presence of CO in your home. Both of these scenarios pose a serious health risk, so it’s important to have the issue corrected immediately. Error code 32 is triggered when there is a problem with the blower motor. The blower motor is the part of the furnace that pushes air through the vents in your home. It’s important to have this part of the furnace checked regularly.

Error Code 39 and 40

Error code 39 is triggered when there is a problem with the flame sensor. This sensor ensures that the burner is receiving the right amount of oxygen so that it can burn properly. In some cases, the error code could indicate a problem with the sensor. In other cases, it could indicate a problem with the wiring to the sensor. Error code 40 is triggered when the pressure differential switch isn’t working properly. This is the switch that determines when the furnace should run. If the switch isn’t working correctly, the furnace may not turn on when it should. This could be a safety hazard, so it’s important to correct the issue as soon as possible.
