In this article, you’ll find out why your Duraflame heater might not be performing and how to troubleshoot the issue. We’ll guide you through common problems and provide practical steps to get your heat back up and running. Keep reading to turn the heat back on without breaking a sweat.

Common Causes of a Duraflame Heater Not Heating

When your Duraflame heater fails to warm your room, several factors might be at play. Understanding the common causes that hinder a heater’s functionality guides you towards the right fix.

Thermostat Issues
Firstly, check if your thermostat settings are correct. The thermostat could be set too low, prompting the heater to shut off prematurely. If the thermostat is dysfunctional, it won’t communicate the right temperature to the heating system.

Faulty Heating Elements
Over time, heating elements can wear out or burn out. Without these elements functioning properly, your Duraflame heater won’t produce heat effectively.

Blocked Air Flow
A clogged filter restricts airflow, which is crucial for distributing heat. Regular cleaning or replacement of air filters is necessary to maintain consistent heating performance.

Electrical Problems
Inspect the power source. An unplugged heater or a tripped circuit breaker could be the reason your heater is not working. It’s also worth checking for any damage to the power cord.

Internal Component Failure
Components within the heater, such as fans and sensors, may fail due to usual wear and tear. These internal issues require a more in-depth look and might need professional servicing.

If you’ve checked these areas and your Duraflame heater still isn’t heating, consult the user manual or contact customer service for further guidance. Remember, regular maintenance can prevent many of these problems, ensuring your heater runs smoothly throughout the colder months.

Check the Thermostat Settings

When your Duraflame heater isn’t heating, thermostat issues are one of the first things you’ll want to investigate. Proper thermostat settings are crucial for your heater to function correctly. To ensure your thermostat is set properly:

  • Verify the temperature setting is higher than the room temperature. If it’s set too low, the heater won’t be prompted to start.
  • Confirm that the unit is switched to ‘Heat’ mode. Some models may have various modes, and it’s easy to overlook this simple yet crucial setting.
  • Check that the thermostat is not obstructed by anything that could alter its temperature reading, such as furniture, curtains, or direct sunlight.

In some instances, the thermostat may need recalibration. Recalibration ensures the thermostat accurately reads the room temperature and activates the heater accordingly. For recalibration instructions specific to your model, refer to the user manual.

If you’ve verified the settings and recalibrated but your heater still fails to heat, the problem might lie with the thermostat’s electrical connections. These could become loose or corroded over time, hindering the thermostat’s operation. Inspect the wiring for any obvious signs of damage and, if you’re comfortable doing so, tighten any loose connections.

Remember, the thermostat is the nerve center of your Duraflame heater’s function. Without proper settings and a fully operational thermostat, your heater is less effective. Regular checks can save you from a chilly surprise on a cold day.

Inspect the Power Source

When your Duraflame heater ceases to emit warmth, it’s crucial to examine the power source it’s connected to. A lack of heating could point to a simple power issue you can easily fix. Start by ensuring the heater is plugged into a working outlet. Test the outlet with another device to confirm it’s functioning correctly.

If you find the outlet operative, inspect the power cord of your heater for any signs of damage, such as fraying or cuts. Damaged cords can interrupt the flow of electricity and prevent the heater from warming up. For safety reasons, if you discover any damage, it’s vital to stop using the heater immediately and have the cord replaced by a professional.

In addition, your heater may have a built-in safety fuse that could trip due to a power surge or overheating. Check your user manual to locate the fuse and assess whether it needs replacing. Remember, dealing with electrical components can be hazardous, so if you’re unsure about any steps, seek assistance from a qualified electrician rather than attempting DIY repairs.

Verify also that the circuit breaker hasn’t tripped, which can occur if the heater draws more power than the circuit can handle. Resetting a tripped breaker can sometimes easily resolve an issue of a heater not heating. If the circuit trips repeatedly, this signals an underlying electrical problem that warrants immediate attention.

Clean or Replace the Air Filter

When your Duraflame heater isn’t heating correctly, one critical area to check is the air filter. The air filter’s primary function is to trap dust, lint, and other airborne particles, preventing them from entering the heater. Over time, this filter can become clogged, which impedes airflow, causing the heater to work inefficiently or not at all.

  • Inspect the Air Filter Regularly
  • Clean the Air Filter
  • Know When to Replace

It’s important to note that operating your heater with a filthy air filter will not only affect performance but could also pose a safety risk. A clogged filter may cause the heater to overheat, which can wear out other internal components more quickly.

When purchasing a replacement, ensure you get the correct size and type for your specific Duraflame model. Manufacturer recommendations generally suggest replacement intervals, but increased use may necessitate more frequent changes.

As part of regular heater maintenance, addressing the air filter is a simple yet effective step towards keeping your heater running smoothly. It not only helps maintain good air quality but also extends the life of your Duraflame heater by allowing it to operate under less stress. Remember, maintaining the cleanliness of your air filter could mean the difference between cosy warmth and the inconvenience of a malfunctioning heater.

Test the Heating Element

When your Duraflame heater stops heating, one of the first components to check is the heating element. This crucial part of your heater converts electricity into heat and is often the culprit if your unit is powered but not producing warmth.

Before You Begin, ensure your heater is unplugged and cool. Safety should be your priority to avoid any potential hazards such as electrical shock or burns.

Locate the Heating Element by referring to your user manual – it’s usually behind the main body panel. You’ll need a screwdriver to remove this panel. Once access is gained, visually inspect the element for any signs of damage, such as breaks or blisters.

Use a Multimeter to test the continuity of the heating element. Set your multimeter to the ohms setting and touch each probe to an end of the element. A functioning element should provide a reading. If the multimeter doesn’t show a reading, the element is likely broken and will need replacement.

Replace the Element by carefully removing it according to the manufacturer’s instructions. Purchase a suitable replacement that matches the specifications for your specific Duraflame model. Installing the new element should be done cautiously, reversing the steps taken to remove it. After installation, reattach the main body panel before plugging in and testing your heater.

Monitor the Heater after replacement to ensure it heats correctly. Regular checks on the heating element can preemptively alert you to future issues. Remember, routine inspections and maintenance can prolong the usability of your Duraflame heater and provide you with consistent warmth during cold days or nights.


Tackling the issue of your Duraflame heater not heating can be straightforward when you know what to look for. Remember, regular maintenance is key to avoiding common problems. If you’ve followed the steps to test and possibly replace the heating element, you’re on the right track. Keep an eye on your heater’s performance and don’t hesitate to reach out for professional help if needed. With a bit of care and attention, you’ll have your cozy warmth restored in no time.
