What should I do if my electric fireplace insert doesn't heat?

Nov 24, 2025

If you're facing the issue of your electric fireplace insert not heating, you're not alone. As a leading supplier of Electric Fireplace Inserts, I've encountered numerous customers with this concern. In this blog, I'll share some practical steps to troubleshoot the problem and get your fireplace back to warming your space efficiently.

1. Check the Power Source

The first and most basic step is to ensure that your electric fireplace insert is properly connected to a power source. Sometimes, the simplest things can cause the issue.

  • Verify the Plug: Check if the plug is securely inserted into the outlet. A loose plug can disrupt the power supply, preventing the fireplace from heating. If the plug seems loose, unplug it and then plug it back in firmly.
  • Test the Outlet: Use another electrical device, such as a lamp, to check if the outlet is working. If the lamp doesn't turn on, the problem might be with the outlet. You may need to reset a tripped circuit breaker or replace a blown fuse. If you're unsure how to do this, it's best to consult a qualified electrician.

2. Examine the Thermostat Settings

The thermostat plays a crucial role in regulating the temperature of your electric fireplace insert. Incorrect settings can lead to the fireplace not heating as expected.

  • Set the Temperature: Make sure the thermostat is set to a temperature higher than the current room temperature. If the thermostat is set too low, the fireplace may not activate the heating element. Adjust the thermostat to a comfortable temperature and wait a few minutes to see if the fireplace starts heating.
  • Check the Thermostat Functionality: If the fireplace still doesn't heat after adjusting the thermostat, the thermostat itself may be faulty. You can test the thermostat by using a separate thermometer to measure the room temperature and comparing it with the thermostat reading. If there's a significant difference, the thermostat may need to be replaced.

3. Inspect the Heating Element

The heating element is responsible for generating heat in your electric fireplace insert. A malfunctioning heating element can cause the fireplace to stop heating.

  • Look for Visible Damage: Carefully examine the heating element for any signs of damage, such as breaks, burns, or discoloration. If you notice any visible damage, the heating element will need to be replaced. However, it's important to note that working with the heating element can be dangerous, so it's recommended to have a professional technician handle the replacement.
  • Test the Heating Element: If there are no visible signs of damage, you can use a multimeter to test the heating element's continuity. A multimeter is a tool that measures electrical current, voltage, and resistance. If the multimeter shows no continuity, the heating element is likely defective and needs to be replaced.

4. Clean the Air Intake and Outlet

Over time, dust and debris can accumulate in the air intake and outlet of your electric fireplace insert, obstructing the airflow and reducing the heating efficiency.

  • Vacuum the Air Intake: Use a vacuum cleaner with a soft brush attachment to gently clean the air intake. Make sure to remove any dust, dirt, or pet hair that may be blocking the intake.
  • Clean the Outlet: Similarly, clean the outlet to ensure that warm air can flow freely into the room. You can use a damp cloth to wipe away any dirt or debris on the outlet.

5. Check the Fan

The fan in your electric fireplace insert helps to circulate warm air throughout the room. A faulty fan can prevent the warm air from being distributed effectively, making it seem like the fireplace isn't heating.

  • Listen for Fan Noise: Turn on the fireplace and listen for the sound of the fan running. If you don't hear the fan, it may be malfunctioning. Check if the fan is blocked by any objects or if there's any debris preventing it from spinning.
  • Test the Fan Motor: If the fan isn't running, you can test the fan motor using a multimeter. If the multimeter shows no continuity, the fan motor may need to be replaced.

6. Consider the Location and Placement

The location and placement of your electric fireplace insert can also affect its heating performance.

  • Avoid Obstructions: Make sure there are no objects blocking the air intake or outlet of the fireplace. Furniture, curtains, or other items placed too close to the fireplace can restrict the airflow and reduce the heating efficiency.
  • Proper Ventilation: Ensure that the fireplace has adequate ventilation. Electric fireplace inserts require proper airflow to function effectively. If the fireplace is installed in a tight space or a poorly ventilated area, it may not heat properly.

7. Contact the Manufacturer or a Professional Technician

If you've tried all the above steps and your electric fireplace insert still doesn't heat, it's time to seek professional help.
