Gibson Furnace Error Codes – How To Troubleshoot Common Issues

‍

When you need to troubleshoot your furnace, it can be quite a process. After all, there are so many different things that could go wrong with a furnace at any given time. Some of these issues might require you to get access to the inner workings of your furnace, which is not always the easiest thing to do. In this blog post, we will go over some common issues that typically arise when using a Gibson furnace and provide solutions for how to troubleshoot them. In this blog post, you’ll learn about some common error codes used by the Gibson Furnace brand as well as steps on how to troubleshoot common issues with your air conditioner or heat pump.

Error Code 16

Error Code 16 is one of the most common issues found with a furnace. When the furnace gets this error, it is basically saying that it needs to be cleaned. The furnace has a built-in system that tells it how dirty it is. Over time, the filters inside the system will get clogged with dust and other dirt, and the system will need to be cleaned. If this error comes up on your furnace, it means that the internal sensors have found that the filter is extremely dirty and needs to be cleaned. If this error comes up, make sure to clean the furnace filters. You might also want to consider changing the filter and keeping a spare on hand just in case.

Error Code 19

Error Code 19 is another common issue found with the Gibson furnace. If this error comes up, it means that the furnace has detected a problem with the blower fan inside the system. The fan is responsible for pushing air through the ducts of the home to cool or heat it. If the blower fan is broken or not working properly, then it will cause this error code to come up. The first thing you want to do when you get this error is to check the blower fan inside the furnace. There should be a button close to the blower fan that you can push to open up the fan. If the fan looks dirty or broken, then you will need to replace it. If the blower fan looks okay, then you will want to clean the furnace blower fan and make sure that the ducts inside your home are not clogged.

Error Code 18

Error Code 18 is another issue common to the Gibson furnace. This error code means that the furnace is having issues with the heat exchanger inside the system. The heat exchanger is the part of the furnace that heats up the coolant inside the system to create hot air. If the heat exchanger breaks down, then it will prevent the furnace from heating up the coolant and creating the hot air needed to heat your home. The first thing you want to do when you get this error is to look inside the furnace and see if you can see any cracks or breaks in the heat exchanger. If you see a crack, then you will need to replace the heat exchanger inside the furnace. If you do not see any damage to the heat exchanger, then you will want to get a professional to come out and inspect the furnace.

Error Code 21

Error Code 21 is another common issue that can come up with a Gibson furnace. This error means that there is a problem with the control board inside the furnace. The control board is responsible for controlling the furnace and making sure that it is working correctly. If the control board is broken or malfunctioning, then it will cause this error to come up. The first thing you want to do when you get this error is to make sure that the wires inside the control board are properly connected. If you find that there are broken wires, then you will need to replace the control board. If the wires are all connected properly, then you will want to get a professional to come out and perform a thorough inspection of the furnace to make sure everything is working correctly.
