Ameristar Furnace Error Codes: Here’s What They Mean and How to Fix Them
Like any piece of machinery, your furnace can experience problems every now and then. Even the most reliable furnaces will begin to show signs of wear and tear after years of use. When this happens, your home will become colder than usual and you might even detect a foul odor coming from your vents. If you suspect issues with your Ameristar furnace are to blame, read on for troubleshooting tips addressing common issues with this unit. As you may know, furnaces are composed of multiple sensors that monitor internal operations at all times. This is to ensure that everything runs smoothly at all times and alerts technicians if something goes awry. If an issue with your Ameristar furnace is detected by one or more sensors, it will activate an error code so you’ll know what needs fixing. In this post, we’ll discuss the error codes associated with the Ameristar furnace as well as how to identify if one has been triggered in your own home.
Error Code 19: Blower Problem
A blower problem means your furnace’s blower is not operating at optimal levels. In other words, it isn’t running as it should be. If this happens, your furnace won’t be able to cycle on and off when necessary, which can cause your home to overheat. When this is detected, the blower problem error code will be triggered. Most blower problems happen because of a clogged or dirty filter. Over time, the filter collects dust, dirt, and other contaminants that must be removed to keep your furnace running smoothly. If you fail to clean or change your filter as needed, your furnace’s blower will become clogged and stop working. To prevent this from happening, clean your filter once each month.
Error Code 20: Burner Or Gas Valve Problem
A burner or gas valve problem means there’s something wrong with your furnace’s burners or gas valve. When this happens, the furnace won’t be able to ignite the gas in the burners to produce heat. A burner problem can be caused by several factors including a clogged or dirty gas valve, faulty spark igniter, or failing flame sensor. For a gas valve problem, you may need to have it replaced by a professional. If the problem is caused by a clogged or dirty gas valve, you can clean it yourself. For a faulty spark igniter or failing flame sensor, contact an HVAC technician to get these issues resolved.
Error Code 21: No Furnace Flame
A no furnace flame error code means that your furnace isn’t able to produce a flame. If this happens, your furnace won’t be able to heat your home. To troubleshoot this issue, start by opening the furnace inspection panel. Then, look for a flashing light that indicates a problem. If you see this light, you’ll need to unplug the furnace and call an HVAC technician.
Error Code 22: Furnace Flame Out
A furnace flame out error code means the flame in your furnace has been extinguished. When this occurs, your furnace won’t be able to produce heat or run the blower. To troubleshoot this problem, check to make sure your pilot flame is lit. Also, be sure that your furnace is receiving enough fuel supply. If the flame went out due to a dirty or clogged burner, you’ll need to clean it or replace the burner. If the problem is caused by a dirty or clogged pilot, you’ll need to clean it or replace the pilot. For a lack of fuel supply, you’ll need to check your furnace’s fuel supply pipe. If it’s clogged, unclog it.
Error Code 23: Electronic Control Problem
An electronic control problem means there’s a problem with your furnace’s control board. When this happens, the furnace won’t be able to run normally. To troubleshoot, check to make sure the power is on at the panel and the circuit breaker hasn’t tripped. Also, check to make sure that the thermostat is wired correctly. If the problem persists, you’ll need to contact a furnace technician.
Error Code 24: Overheat Protection Problem
An overheat protection problem means your furnace has been overheating. If this happens, the furnace will shut off until it cools down. If your furnace overheats, get it serviced right away to avoid any damage or fire hazards. To troubleshoot this issue, check to make sure there aren’t any obstructions in the return or exhaust vents. Also, check to make sure the filter is clean and correctly installed. If these issues persist, call an HVAC technician.
Ameristar Furnace Error Codes Conclusion
While these error codes will help you troubleshoot issues with your Ameristar furnace, remember that they can also be a sign of a more severe problem. If your furnace is triggering an error code more than once, it could be a sign that it’s worn out and needs to be replaced. If you suspect your furnace needs servicing, don’t hesitate to contact a professional.
