The issue happens because of a defective outlet or loose plugin. 


Monitor your heater cord and plug connection. A faulty wall outlet connection or loose plug can cause the outlet or plug to get heat up. 

Be certain the plug fits tightly in the outlet. Heaters draw more current than small appliances. Overheating of the outlet may occur even if it has not happened with the use of other appliances.

10. Remote Control Is Not Working

Duraflame remote control troubles may be noticed when the remote control is missing batteries or battery power. It may be because of the poor signal or your distance.

Use the remote from less than 20 feet distance from the front of the heater. And always use the remote pointing at the control panel of your heater.

  • After 10 seconds without control input, the heater will exit the thermostat calibration.

12. Heater Flame Not Working

If you discover the heater flame is not moving, possibly, it’s occurring for 2 issues:

  • Faulty flame generator drive motor 
  • And the spinner is detached from the heater motor


Get a new flame generator drive motor and replace it. Remove the ember bed, back panel & metal bracket. Then, check if the spinner of the heater is correctly mounted to the motor or not. 

If it’s not rightly mounted, mount it perfectly and replace the back panel, metal bracket, and ember bed. The issue will be solved.

Duraflame Heater Error Codes

In this section, we will explore the common Duraflame infrared heater error codes and their easy solutions:

1. Error Code E1

If you find the heater display is showing “E1”, think, the possible cause is that the thermostat sensor of your heater is broken or disconnected.


Unplug the heater, separate the back panel and examine that the thermostat is plugged into the main circuit board. If this does not resolve the problem, contact the customer service of Duraflame for a replacement thermostat sensor.

2. Error Code E2

Showing the “E2” on the heater display means the thermostat sensor of the heater is broken.


Contact customer service for a replacement thermostat sensor.

3. Error Code E3

When you notice the Duraflame display is showing E3, know it’s happening because the manual reset overheats the protection of the heater and has been set off or triggered.


If you notice the “E3” is shown on the display, first visually inspect whether the air inlets and outlets of the heater are broken or not. If they are broken, the issue will cause overheating. 

And the overheating causes the Duraflame e3 error code to show. Firstly unplug the heater and allow it about 3o minutes to cool down. 

When you find the heater is cool enough, again plug the heater and run it. The problem will be solved.

Yet, if you notice the heater is showing the sign, feel free to contact the customer service of Duraflame. They will solve the issue.

4. F5 Error Code

F5 is not an error code. You will find five brightness levels from F1-F5 on your Duraflame heater. F5 is the highest brightness and F1 is the lowest one. You can also select (00) which means you are selecting the OFF setting.

  • Make sure the power cord is plugged in correctly in the outlet.
  • Unplug the heater and check out to find if there is any loose connection in the outlet and fix it.
  • Clean the outlet and inlet if there is any blockage. And never forget to switch off the circuit breaker before cleaning the outlet or inlet blockage. In such a case, it would be wise to take help from a professional because it’s a risky job. 
  • Finally, you can try resetting your heater to fix the ER error code when you notice it on the display.

      If the flame generator is the culprit, change it. Plus, check the spinner is mounted correctly, if not fix it. For better understanding, you can go to my post and read again the point 6.

      I hope, you will get the solution.


  1. I have a older Duraflame and the code on it flashes F3 and stops heating the blower shuts down but the fake flame keeps going or stays on . Thank you

    • Hi Mike

      If you notice the “E3” is shown on the display, first investigate whether the air inlets and outlets of the heater are broken or not. If they are broken, the issue will cause overheating.

      And the overheating causes “E3” showing. Firstly unplug the heater and allow it about 3o minutes to cool down. When you find the heater is cool enough, again plug the heater and run it. The problem will be solved.

  2. I figured it out. On the inside of the door along the bottom are the manual controls. Which you can raise the temp and how long to run. The remote will not do this. All directions I read was trouble shoot on things not associated with the issues. Please have people look there 1st.

  3. My duraflame doesnt have a dial for the thermostat and when I press the thermometer button only thing that happens is the light blink the display never show the temp.

  4. Thank you! My flame wasn’t turning on and it was a simple fix –> replace the light bulb. Easy, with a standard 40watt 120v bulb…simply take off the back and replace bulb. Then put the back back on. Viola! I got a flame!

  5. Spinning wheel under logs seems to be making noise
    Almost like it may be bent or is catching on something

    Or is this noise normal?

    • Hi John

  6. I had to replace the blower assembly on a model DFI59101. I’m not sure if I got all the wires connected right. Could you send me something to show me what goes where? Thank you.

    • Hi Joe

      In this regard, you can check the manual of your heater to find the wiring connections.

      Alternatively, it’s a good idea to take a pic of the wiring connections before replacing the blower. Then, you can connect them accordingly.

      Best of luck!
