What To Do When Your Ruud Furnace Is Showing An Error Code

When your furnace experiences an error, it’s typically because something isn’t working correctly. Your system could have a minor mechanical issue or maybe something more serious is going on. Either way, recognizing when your Ruud furnace is giving you an error code and knowing how to troubleshoot the issue can help you get it back up and running as quickly as possible. If you own a Ruud furnace and it starts flashing error codes, don’t panic! These codes are designed to help technicians troubleshoot problems faster and more efficiently. Once you understand what the problem is, solving it will be much easier. With that in mind, read on for information about what different error codes mean and how to troubleshoot them so your home feels cozy again soon.

Error Code 21

Error code 21 indicates that your furnace has detected a problem with the air filter. If it’s dirty, it could become clogged, restricting airflow and causing your furnace to overheat. Dirty filters can also reduce the overall efficiency of your furnace, meaning you’ll have to spend more money on utilities. If your air filter is clogged, change it immediately to avoid a full-blown furnace failure. Be sure to check your filter regularly and clean it whenever it’s visibly dirty. If you don’t have a regular filter-changing routine, consider setting a calendar reminder to help ensure you don’t forget to do it!

Error Code 22

Error code 22 indicates a problem with the pressure switch. To keep your house safe, your furnace has a pressure switch that opens if there’s not enough pressure to keep the flue open. When this happens, the switch opens and shuts off the furnace to prevent carbon monoxide from leaking inside. Ruud furnaces have two pressure switches: primary and secondary pressure switches. The primary pressure switch is inside the furnace and the secondary pressure switch is mounted on the rear outside wall of your home. If either of these switches is faulty, error code 22 will show up on your furnace. What causes error code 22? The most common reason for this error code is a dirty pressure switch. If the switch is clogged with debris, it won’t close properly, causing the error code to appear. If you own a Ruud furnace and error code 22 appears, try cleaning the pressure switches—the primary switch inside the furnace and the secondary switch located on the outside wall of your home.

Error Code 23

Error code 23 indicates a problem with the blower motor. If your blower motor has stopped working or has been damaged, your furnace won’t be able to push warm air through your home. If the blower motor isn’t working properly, error code 23 will display on your furnace. If your furnace has been running for a long period without producing any heat, the blower motor may have burned out. If you’ve recently installed a new Ruud furnace, you may have noticed that the motor is much quieter than what you’re used to. That’s because furnaces have evolved significantly over the years—the blower motor itself has gotten quieter and uses far less energy than it used to!

Error Code 24

Error code 24 indicates a problem with the second limit switch. The secondary limit switch is a safety mechanism that turns off the furnace if the primary limit switch isn’t operating properly. If the secondary limit switch detects a problem, it will display error code 24. If your furnace seems like it’s running but isn’t producing any heat, the second limit switch may be faulty. You should have a professional come out and inspect the switch to be sure, but if the switch is dirty, it could cause error code 24 to appear. What causes error code 24? The most common reason for this error code is a dirty limit switch. If your secondary limit switch is clogged with debris, it won’t close properly, causing the error code to appear.

Error Code 25

Error code 25 is triggered by a problem with the primary limit switch. The primary limit switch is a safety mechanism that turns off the furnace if the secondary limit switch isn’t operating properly. If the primary limit switch detects a problem, it will display error code 25. If your furnace seems like it’s running but isn’t producing any heat, the primary limit switch may be faulty. You should have a professional come out and inspect the switch to be sure, but if the switch is dirty, it could cause error code 25 to appear. What causes error code 25? The most common reason for this error code is a dirty limit switch. If your primary limit switch is clogged with debris, it won’t close properly, causing the error code to appear. What Can Ruud Furnace Error Codes Do To Your System? Ruud furnace error codes can cause a range of problems for your system. For example, a clogged air filter will decrease the overall efficiency of your furnace. If your furnace is working harder than it needs to, it will break down faster than if it were operating correctly. An error code can also cause a minor malfunction or an interruption to your system. For example, if you have a dirty pressure switch, it might not close properly, causing your furnace to shut off and restart. Over time, this could cause your system to become damaged, which is why it’s important to troubleshoot issues as soon as they arise. Your system can also experience a major malfunction if the furnace shuts off without warning. This is a serious issue and can lead to expensive repairs if it’s not dealt with immediately.

Error Code 26

Error code 26 indicates a problem with the electrical connector. This issue typically happens if you’ve recently installed a new furnace and the installer didn’t properly connect it. If the furnace installer didn’t properly connect the furnace, error code 26 will display on your system and your furnace won’t operate. Unfortunately, there aren’t many ways to troubleshoot this issue, but you can call an electrician to come out and fix the connector. What causes error code 26? The most common reason for this error code is that the electrical connector isn’t properly connected. If the installer didn’t connect your new furnace correctly, error code 26 will appear. What Should You Do If Your Ruud Furnace Is Showing An Error Code? If your furnace is showing an error code, it’s important to address it as soon as possible. The longer you wait to troubleshoot and solve the problem, the more serious it could become. What should you do if your Ruud furnace is showing an error code? Start by contacting a professional furnace repair technician. A technician can troubleshoot your issue and let you know what caused the error code to appear.
