3 Easy Ways to Diagnose an American Standard Furnace Inducer Error
The Inducer is the part of your American Standard furnace that helps distribute conditioned air throughout your home. In order for it to do so effectively, these devices need to be in working order and calibrated properly. If you have an AC furnace with a standard inducer, we’ll show you how to diagnose the common issues that come with this type of system and help get it running smoothly again. If you see red or yellow lights on your AC furnace, this indicates a problem with your inducer. The red light indicates an over-limit condition which means airflow is restricted (reducing combustion) or carbon monoxide levels are too high (reducing combustion). The yellow light indicates a value above or below the normal operating range of the inducer. This could be due to excess grease, clogs, or other issues. Here are 3 ways to diagnose an American Standard furnace inducer error:
Check the pressure switch
The pressure switch on your furnace controls the amount of gas that is distributed to the inducer when the furnace comes on as well as the temperature. A clogged or broken pressure switch can cause yellow or red lights on your inducer. You can check the pressure switch for any physical damage and ensure it is set to the appropriate temperature for your home. If the pressure switch is damaged, you will need to replace it. This can be done by a professional or by following this guide: – Disconnect the pressure switch wires and remove the front panel of your furnace. – With the panel off, disconnect the wires from the pressure switch. – Disassemble the pressure switch and clean it thoroughly. – Reassemble the pressure switch and reinstall it back in the furnace. – Turn your furnace on and check the inducer light.
Run a diagnostic test
You can use a diagnostic test to help determine if there is an issue with your inducer. This is a simple way to check the functionality of your system without having to remove any parts and will let you know if your system is in good working order or not. Keep in mind that if there is an issue with your furnace, it will not be able to complete the test. Here’s how to run a diagnostic test with your inducer: – Turn the AC off in your home and unplug the furnace (make sure to unplug it from the wall and not just turn off the switch). – Open the furnace and remove the inducer. – Plug the inducer into a diagnostic test device. – Start the diagnostic test. – Turn your AC system back on. If the inducer lights turn off while running the test, you have an inducer problem. If the inducer lights stay on, your system should be fine.
Check for clogs
A clogged inducer might be the culprit if your inducer light stays on. Inspect the inside of your furnace for any blockages and clean them out (although this is a job best left to a professional). Be sure to check the ductwork as well. If there is a clog in the ductwork, your furnace will not be able to distribute conditioned air throughout your home. You can check the ductwork for a blockage using a CO sensor. If the CO readings appear abnormally high, there is likely a blockage in the ductwork.
Replace your inducer motor
If all else fails, you may need to replace your inducer motor. This is a common issue with standard inducers and can be a big problem if not diagnosed early. Signs of a problem with the inducer motor include yellow and red lights being on and a high CO reading. To replace your inducer motor, you will need a few tools and parts from your local hardware store. Here’s what you’ll need: – Inducer motor – Inducer motor mounting bracket – Inducer motor mounting screw – Inducer motor wire harness – Electrical tape – Wire strippers – Soldering iron – Electrical tape At the end of the day, you want to make sure you have a furnace that’s working correctly at all times. Diagnosing and fixing inducer issues as they arise will help reduce the overall cost of maintaining your furnace.
