Maytag Neptune Dryer Troubleshooting Codes
After running diagnostics on your Maytag Neptune dryer, you’ll likely get an error code that tells you what’s wrong with your dryer. Now that you have the error code, how do you interpret it?
Well, here’s a guide to troubleshooting typical Maytag Neptune diagnostic codes:
1. ‘Check Vent’ or AF Error Code or Code F4E3
The Check Vent F4E3 or AF error code indicates restricted airflow associated with a clogged vent or lint screen. The vent could also be kinked or crushed or have many elbows.
So, you’ve to inspect the vent for any blockage and clear it to facilitate airflow.
You need to check the lint filter for dirt clogging and clean it. Then move the dryer vent and clean it too if it’s clogged, remove any kinks and if it’s crushed, replace it.
2. Error Code 01
The error code 01 shows a problem with the thermistor. It could be that the thermistor is defective or appears so when it’s not due to a clogged exhaust vent. So, you should check the thermistor and the exhaust vent too.
Start by inspecting the exhaust fan for clogging. If it’s blocked, unclog it, but if nothing is wrong with it or the error won’t clear after unclogging it, replace the thermistor.
3. Error Code O2 (Neptune Maytag Dryer Not Heating)
The error code 01 indicates that the Maytag Neptune dryer is not heating. The reason could be a failed power supply due to a tripped breaker, a partially opened gas valve, power loss, or a failed heating component such as the heating element. So, you’ve to consider all these factors.
Consider unplugging and plugging back the dryer to ensure it will start. While at it, reset the breaker if tripped and ensure there’s no power loss. And if the dryer is gas-powered, ensure you fully open the gas shutoff valve.
4. Error Code L2, F4E4, or F31
The error code L2 or F4E4 pops up when there’s an issue with the power supply, preventing the heater from switching. So, while the dryer may turn on, it won’t get hot.
Sometimes, the source of the power failure is a loose cord, tripped breaker, or overheated fuse. So, you need to check them to ensure they aren’t disrupting the dryer’s power supply.

The error code 03 suggests a faulty door switch or damaged door switch’s wiring harness. Thus, you must check the door switch and its wiring harness to ensure they are not defective.
Inspect the wiring harness and door switch for breakages and damages; if any of them look faulty, replace them.
6. Error Code 04
Error code 04 suggests a control board or drive motor fault. Either part could be faulty, or it could be the case of loose wiring, causing the components to malfunction.
Check the wiring harness for looseness or damage and replace it. But if the wiring harness is okay, replace the control board.
7. ‘Check Lint’ Error Code
The ‘check lint screen’ or ‘check lint’ indicator light will come on when the lint screen is filthy. If so, you need to check the lint screen for dirt clogging. While this error code may not prevent the dryer from starting, it may not heat up or dry your clothes.
Check the lint screen as the error code indicates and wash it with soapy water. Then check the outside vent for clogging and clear it. It could be the reason the lint screen is blocking.
8. Error Code PF
The error code PF stands for power failure. So, you ought to check the dryer for possible power interruption, which can be an outage, tripped breaker, or electrical fault.
Confirm if there’s an outage. If there isn’t, check the breaker to see if it’s off. If it is, flip it back on. But if the breaker is not the issue and there’s no outage, control a certified electrician to check and fix any electrical fault.
9. Error Code 08
Lastly, the error code 08 pops up to indicate a stuck control panel key. Such a key renders the control panel non-working.
Inspect the control panel for any stuck keys and press them on the side to release them. But if the buttons are faulty or the control panel won’t become responsive, replace the control panel.
10. Error Code F3E2
The error code F3E2 pops up when the dryer dries up five loads successively without registering any moisture sensor information.
Clear this error code by pressing the power button and restarting the dryer. If the error doesn’t clear, contact an expert technician.
11. Error Code F1E1 to F1E5
The error code F1E1/F1E3/F1E4/F1E5 indicates a control unit fault or an issue with its associated wiring. So, you need to reset the dryer to fix the control board.
Consider resetting the control unit by pressing power on the dryer and selecting a new cycle. After that, press the start/pause button for a few seconds. But if the Neptune dryer won’t reset, unplug it for 30 minutes or so to hard reset it.
12. Error Code F6E2/6E/F01/F02/F22/0E/E1/E2/E3/F6E3/F29/F50/F70-F78
Any above error codes indicate that your dryer needs a reboot or reset.

Are error codes something that appear when you first start the dryer?
Error codes can appear on the display panel of certain dryers, including Samsung models, to indicate potential issues or malfunctions. However, since I am not extensively familiar with Samsung dryers, I am unable to provide a definitive answer to your question. It would be best to consult a Samsung technician who frequently deals with these specific dryers and is well-versed in their functionality. They should be able to provide you with the accurate information you seek.
What could be the issue if a Samsung dryer runs but doesn’t heat?
How can I troubleshoot and fix the issue of a running but not heating dryer?
To troubleshoot and fix a running but not heating dryer, you can follow these steps:
What could be the reason for my dryer running but not heating?
If your dryer runs but doesn’t heat, it is likely due to a power issue. The dual breaker in the house breaker box may be tripped, resulting in the dryer only receiving 120 volts instead of the required 240 volts. Another possible reason could be a faulty or burnt wire in the access panel where the power cord wires mount on the dryer terminal block.
What should I check if my dryer runs but doesn’t heat?
If your dryer runs but doesn’t heat, there are a few things you can check. Start by checking the dual breaker in your house breaker box. If one breaker is tripped and the other is not, it can result in the dryer only getting 120 volts instead of the required 240 volts to heat. Additionally, you can check the voltage at the terminal block where the dryer power cord hooks up. Use a multimeter to check for 240 volts across the two outer terminals. If there are any burnt wires in the access panel where the power cord wires mount, that could also be the cause.
If you are experiencing a situation where your Samsung dryer is running but not producing heat, there are several potential issues that could be causing this problem. Here are some troubleshooting steps to consider:
1. Error Code PF: This error code indicates a power failure. It is important to check for any power interruptions, such as an outage or a tripped breaker. Additionally, an electrical fault could also be the culprit behind the lack of heat.
2. Error Code 08: This error code specifically points to a stuck control panel key. When a key on the control panel gets stuck, it renders the entire panel non-functional. In such cases, it is necessary to address the stuck key issue to restore proper functionality.
3. Error Code F3E2: If your dryer has dried up five consecutive loads without registering any moisture sensor information, the error code F3E2 may appear. This indicates a potential problem with the moisture sensor and may require further investigation or maintenance.
4. Error Code F1E1 to F1E5: These error codes suggest a fault in the control unit or an issue with its associated wiring. To address this, a simple reset of the dryer can often fix the problem. Try unplugging the dryer for at least 5 minutes and then plug it back in to clear the error code.
5. Error Code F6E2/6E/F01/F02/F22/0E/E1/E2/E3/F6E3/F29/F50/F70-F78: Any of these error codes may indicate the need for a reboot or reset of your dryer. To perform a reset, simply unplug the dryer for a few minutes and then plug it back in. This should clear the error code and potentially resolve the heating issue.
It is worth noting that while these error codes provide insight into potential problems, they may not directly address the specific issue of a running dryer that does not produce heat. For more thorough troubleshooting, it is recommended to follow the steps outlined in Their article. This includes checking the dual breaker, inspecting the terminal block for voltage, and examining for any burnt wires in the access panel. By following these additional steps, you can further pinpoint the cause of the heating problem and take appropriate action to resolve it.<
