Why Duraflame Heater Keeps Shutting Off [Solved]

Here, we will talk about each and every reason why the Duraflame heater shuts off. Let us take a look at the details behind the issue and their solutions. 

1. Overheating

One of the major reasons that cause the Duraflame heater shuts off after a few minutes is overheating. When the heater overheats, the safety sensor inside the system detects the high temperature.

In order to prevent damage to the heater and keep it safe, the sensor turns off the heater upon detecting overheating. 

Now, the reason behind the Duraflame overheating is due to improper airflow or accumulation of dirt inside the heater. 

How To Fix It

In order to solve the Duraflame heater overheating issue, follow the steps mentioned below:

  • Check the airflow to the heater and make sure that the pipes are clean. Properly clean the air pipes and remove an object blocking the air vents. 
  • Take out the filters at the bottom of the heater and remove all the dirt, debris, or buildup accumulated in the filters. Maintain a cleaning schedule and clean the filters on a regular basis. 

Tip: Make sure that you turn off the heater and let the temperature drop down before examining or cleaning the filters and pipes. 

2. Malfunctioning Sensor

Another common reason behind the Duraflame heater shutting off is the malfunctioning safety sensor. The work of the sensor is to detect the temperature of the heater and shut down the operations if it exceeds the safe limit.

If the sensor is damaged or malfunctioning, then it won’t be able to detect the temperature properly and shut down the heater. 

How To Fix It

Turn off the Duraflame heater and let it cool down properly. Check the safety sensor connected to the heater and make sure that it’s in perfect working condition. Repair or replace the sensor with a new one and turn the heater back on. 

3. No Power

In order for the Duraflame heater to function properly, it’s essential to establish a proper electric connection between the heater and the power outlet. The Duraflame heater won’t work if there is no power from the power outlet. 

If the power outlet is malfunctioning or damaged, then it won’t be able to establish a secure and proper connection with the heater. This will result in the heater shutting off. 

How To Fix It

Turn off the Duraflame heater and unplug it from the power outlet. Check whether the outlet is working properly and plug the heater in another functioning power outlet.

Turn the heater back on and make sure that it’s working perfectly and without any trouble. 

4. Thermostat Trouble

The thermostat is undoubtedly one of the most important parts of the Duraflame heater. If the thermostat isn’t working properly or set at the wrong temperature, then the Duraflame heater won’t function. 

A malfunctioning thermostat will prevent the heater from heating up properly and will cause it to shut off. If the thermostat is set at a lower temperature compared to the temperature in the room, then the heater won’t heat up and turn off. 

How To Fix It

  • Check the thermostat connected to the Duraflame heater and make sure that it’s in proper condition. Repair or replace the thermostat with a new one and turn the heater on. 
  • Keep an eye on the temperature setting of the thermostat and set it at the right temperature. Make sure that the temperature on the thermostat is higher than the temperature of the room. 

5. Blown Fuse

Another highly common reason that causes the Duraflame heater to shut off is a blown fuse. When the fuse in the control board blows up, it trips off the connection between the control board and the heater. Thus, the Duraflame heater shuts off on its own. 

How To Fix It

Turn off the heater and wait for the temperature to cool down completely. Open the control board and check the fuse.

Replace the fuse with a new one and turn the heater back on after closing the control board. 

6. Damaged Wires

Similar to the power outlet issue, faulty or damaged wires also prevent the Duraflame heater from establishing a proper connection.

If the wire is damaged or loose from the connecting point, then it will cause the heater to shut off. 

How To Fix It

To solve the Duraflame heater wiring issue, follow these steps:

  • Check the wiring connected to the heater and make sure that it’s properly connected. Take help from the Duraflame heater manual to place the wiring in place properly. 
  • Examine the wires and look for any damaged or skinned wires that prevent the connection from establishing. Replace the wire with a new one and connect it properly. 

7. Malfunctioning Heating Element

The purpose of the heating element or ignitor in the Duraflame heater is to heat up the system. If the heating element is damaged or not working properly, then it won’t heat up and the sensor won’t detect any temperature. This will result in the Duraflame heater shutting off. 

How To Fix It

Turn the heater off and check the heating element to make sure that it’s in proper working condition. Replace the heating element and set it properly in place.

Turn on the heater and see whether it’s functioning normally or not. 

How To Clean The Duraflame Heater

As we discussed earlier, the filters and air pipes of the Duraflame heater need to be cleaned on a regular basis. This will ensure the proper performance of the heater and prevent the issue of overheating and clogging the filters and pipes. The steps for cleaning the filters and pipes are:

  • Turn off the heater and let the temperature cool down completely. 
  • Take out the filters from the heater and vacuum the accumulation of dust, debris, and so on from the air filters. 
  • Place the filters back in place and secure them properly. 
  • After cleaning the filters, vacuum the dirt buildup in the air pipes properly. 
  • Turn the heater back on to ensure that it works perfectly. 


What Happens When The Duraflame Heater Reaches The Preset Limit?

The Duraflame heater will generate heat until it reaches the temperature set on the thermostat. The heater will shut off its operations once it reaches the preset limit. 

How Long Does It Take For The Duraflame Heater To Heat Up?
