How to Clear the Payne Furnace Error Code 34
When you’re using an industrial furnace or burner, you may encounter a range of errors. You should expect some of these error codes and be prepared to address them when they occur. If your Payne combustion chamber has the error code 34, there is a problem with the secondary air system – possibly with the air filter, exhaust pipe, or ducting. Your maintenance team will need to check these areas and make repairs where necessary. If your Payne combustion chamber displays ERR code 34 during a start-up test, it is because there is an issue with the secondary air system. The secondary air system helps introduce fresh air into the fuel intake. It also can detect any carbon monoxide in the exhaust gas stream before it leaves the combustion chamber. When this fails to happen optimally, ERR code 34 will appear on your chamber’s display screen and remain there until the problem is fixed.
Error Code 34: Meaning and Explanation
The first digit of the error code gives us the section that’s causing the fault: In this case, it’s a problem with the secondary air. The next two digits indicate the sub-section within that section is the problem: In this case, it’s the Control T-Section. Then the last digit is a code that tells us the specific problem: In this case, it’s a fault with the solenoid control.
How to Fix Payne Furnace Error Code 34
There are a few things you can do to troubleshoot this issue. First, make sure that you have a working SSV. You should hear it cycling on and off while you run the combustion test. If this is not the case, you need to repair the SSV. Once you’ve done that, clear the combustion chamber and run a new start-up test. If the error code 34 still appears, you will have to check the air supply ducting. Make sure that it has no kinks or blockages. Also, inspect the air filter for any tears or holes. If you notice any damage, you will need to replace the filter. Once you’ve done that, run another start-up test. If the error code 34 still appears, you may have a faulty ECM. If that is the case, you will need to replace the ECM.
Resetting the Combustion Chamber
If your combustion chamber has a frozen or stuck start-up test, you will need to reset it. This is easy to do if you know what you’re doing. First, turn off the power to the furnace. Then, press and hold down the STOP button on the front of the combustion chamber. After 10 seconds, release the STOP button. You should hear a BEEP sound. Next, press and hold down the START button for 10 seconds. After you’ve done that, release the START button. Now you can run another start-up test.
Resetting the Electronic Control Module (ECM)
If your combustion chamber has a frozen or stuck start-up test, you will need to reset the ECM. This is a little more complicated than resetting the combustion chamber. You may want to consult with your furnace service company if you’ve never done this before. First, turn off the power to the furnace. Then, disconnect the power cable from the back of the combustion chamber. Next, remove the side cover from the combustion chamber. After that, locate the CPU board and push the RESET button. Then, reconnect the power cable to the back of the combustion chamber. Finally, turn the power back on to the furnace. Now you can run another start-up test.
Resolving a Failed or Stuck Solenoid Valve (SSV)
If you’re experiencing issues with the SSV, you need to repair the SSV. First, turn off the power to the furnace. Then, remove the side cover from the combustion chamber. After that, locate the SSV, which is usually near the air ducting. If the SSV is stuck (which often happens), you will need to clean or oil it. If the SSV is burnt out, you will need to replace it. While you’re there, make sure the air intake ducting isn’t blocked or kinked. You should also inspect the air filter for tears or holes. If you notice any damage, replace the air filter. Now you can turn the power back on to the furnace and run another start-up test.
Repairs to the Air Supply Ducting and Filter
If the air supply ducting is damaged, you will need to either patch it with duct tape or replace it. If you need to replace the ducting entirely, you need to make sure that you install a new air ducting that is of equal or higher quality than the original ducting. If you repair the air ducting, be sure to clean out the air filter before reusing it. If the air filter is torn or ripped, you will need to replace the air filter.
Conclusion
You must know how to clear the Payne furnace error code 34, as it is a safety hazard. If error code 34 is not fixed, there is a risk of carbon monoxide poisoning, which could lead to death. If you have any questions about troubleshooting the error code 34 on a Payne furnace, don’t hesitate to contact a professional.
