Why My Duraflame Heater Keeps Shutting Off [Reasons + Solutions]

In this section, we’ll take an in-depth look at how to stop your heater from shutting off repeatedly. We break down the solutions on the basis of the reasons behind the issue. Carry out the solution that suits your situation best. Let’s get started!

1. Overheating

The number one reason why your Duraflame heater may be shutting off is overheating. Fireplaces have fail-safe sensors these days that shut off the unit when it is overheated.

This protects the unit from damage. Chances are, your unit has overheated, making this sensor go off and the unit shut down.


To solve this issue more permanently, we have to prevent overheating. Usually overheating is caused by a lack of airflow. Try placing the unit in a place that allows for healthy airflow. Avoid restrictive locations where the unit will be surrounded by too many objects.

There may also be a lot of lint build-up in the unit. Clean the filter of the unit to fix this issue. Remember to turn off the power before doing this.

Turning on the unit after it’s been kept off and disconnected from the power for a while should reset the electric fireplace as well. Resetting the fireplace also is a quick fix for overheating issues.

2. Defective Thermostat

Usually, electrical fireplaces have thermostats with multiple temperature settings. These settings range from off to high. When the room reaches the temperature setting of your choice, most modern units will shut off. That is how they are designed.

Sometimes, the bulbs used in the thermostat are off high wattage and reach a higher temperature quickly. Consequently, your unit is shutting off even when the room hasn’t reached the desired temperature.


Here’s what you can do. Set a higher temperature setting on the thermostat if you don’t want your unit to keep turning off. In case, the bulbs in your thermostat are causing the issue, consult a licensed electrician for advice on bulb replacement. 

Well, instead of replacing the bulb on your thermostat, it’s better to get a new thermostat to fix your fireplace shutting off repeatedly.

3. Blown Fuse

Check to see if the fuse is blown. This may be caused by a bad motor that draws in too much power. When this happens, the fuse is tripped and your unit shuts off.


In this case, we recommend you contact a certified electrician to fix the problem if you don’t have any expertise in working with electrical appliances. Fixing the motor is no small task. It can get complex and tricky.

It is even better if your unit is still under warranty. You can contact the manufacturer or its local dealer to take a look at your fireplace.

4. Dirt Build-Up In Heater Element

Dirt build-up could be a reason why your unit is shutting off repeatedly with a beeping sound. It is very important to keep cleaning your unit after every six months or so.

Maintaining your unit properly is much better than spending hundreds of dollars to replace parts and service the unit later.


Turn off the power supply and unplug your unit. Ensure that it is cool before cleaning it. Here’s how you clean your unit:

Step 1: Take a lint-free piece of cloth. Soak it in a hot soap-water solution and wring it out well. With this damp cloth, clean the exterior of your fireplace. Pay extra attention to the firebox ember bed and air inlet/outlet of the heater.

Step 2: With the same damp cloth, clean the glass of your electric fireplace. Don’t use harsh chemicals.

Step 3: Now it’s time to clean the interior. We won’t be using the damp cloth anymore. Instead, grab your vacuum and dry cloth. Clean the blower fan of any dirt by vacuuming it first. Then, remove the remaining dust with the cloth.

Your fireplace has a flame effect compartment. Clean the parts that are reachable as carefully and lightly as your can. Clean the ember bed with a vacuum and wipe it with a dry cloth.

Step 4: Close your fireplace up. Reconnect it to the power and turn the heater back on.


How do you set the thermostat on a Duraflame heater?

You can’t change the thermostat setting with the remote. For that, you have to go to the control panel. There’s a heater button on the control panel. Pressing it will change the temperature setting by 1° C. 

What does E3 mean on the Duraflame heater?

E3 error code on the Duraflame heater indicates that the heater needs a manual reset due to overheating. Unblocking the heater inlets and outlets, if something is restricting them, can prevent overheating. To fix the error code, unplug the heater and wait for 5 minutes at least for the heater to cool down. Turning the heater back on at this point is okay. The error code will no longer be there.

Why is my electric fire blowing cold air?

When your thermostat temperature setting is below the temperature of the room and the fan in your heater is kept on, your heater will blow out cold air. Resetting the temperature to a higher degree will fix this issue. Another reason could be that your heater’s manual reset has tripped. Resetting the heater will solve the issue as well. 

Where is the light bulb in an electric fireplace?

Generally, the light bulb is located at the unit’s center.

Why is my fireplace beeping?

If your Duraflame heater keeps beeping it means the remote control receiver unit needs a change of batteries. Change receiver batteries and remote batteries when necessary. 


Now you are armed with all the information you need, hopefully, your Duraflame heater keeps shutting off no longer. Enjoy warm air all winter!
