What To Know

  • If your electric heater is too small for the room you are trying to heat, it will not be able to produce enough heat to warm the space.
  • Make sure you choose a heater that is the right size for the room you are using it in.
  • If your electric heater is too small for the room you are trying to heat, you will need to choose a larger heater.

Electric heaters are a common way to keep warm during the winter months. However, sometimes they can start blowing cold air instead of warm air. This can be frustrating and uncomfortable, especially if you’re trying to stay warm in a cold room. If your electric heater is blowing cold air, there are a few possible reasons why.

Reasons Why Your Electric Heater Is Blowing Cold Air

1. Thermostat Setting: Check the thermostat setting on your electric heater. If the thermostat is set too low, the heater will not be able to produce enough heat to warm the room. Make sure the thermostat is set to a temperature that is at least 5 degrees Fahrenheit higher than the current room temperature.

2. Dirty Filter: The filter in your electric heater can become clogged with dust and debris over time. This can restrict airflow and prevent the heater from producing enough heat. Clean the filter regularly according to the manufacturer’s instructions.

3. Damaged Heating Element: The heating element in your electric heater can become damaged over time, especially if the heater is used frequently. This can cause the heater to blow cold air instead of warm air. If you suspect that the heating element is damaged, you should have it replaced by a qualified technician.

4. Faulty Fan: The fan in your electric heater is responsible for circulating the warm air throughout the room. If the fan is not working properly, the heater will not be able to distribute the heat effectively. Check the fan to make sure it is running smoothly and that there are no obstructions blocking the airflow.

5. Overheating: If your electric heater is overheating, it may automatically shut off to prevent damage. This can cause the heater to blow cold air until it cools down. Check the heater for any signs of overheating, such as a burning smell or excessive heat. If you suspect that the heater is overheating, turn it off and let it cool down before using it again.

6. Electrical Issues: Electrical problems can also cause your electric heater to blow cold air. Check the power cord and plug to make sure they are in good condition and that there are no loose connections. You should also check the circuit breaker or fuse that powers the heater to make sure it is not tripped or blown.

7. Incorrect Heater Size: If your electric heater is too small for the room you are trying to heat, it will not be able to produce enough heat to warm the space. Make sure you choose a heater that is the right size for the room you are using it in.

How to Fix an Electric Heater That Is Blowing Cold Air

1. Adjust the Thermostat: If the thermostat is set too low, adjust it to a higher temperature.

2. Clean the Filter: Remove the filter from the heater and clean it according to the manufacturer’s instructions.

3. Replace the Heating Element: If the heating element is damaged, you will need to have it replaced by a qualified technician.

4. Fix the Fan: If the fan is not working properly, you may be able to fix it yourself by cleaning it or replacing the motor. However, if the fan is damaged, you will need to have it replaced by a qualified technician.

5. Let the Heater Cool Down: If the heater is overheating, turn it off and let it cool down before using it again.

6. Check the Electrical Connections: Make sure the power cord and plug are in good condition and that there are no loose connections. You should also check the circuit breaker or fuse that powers the heater to make sure it is not tripped or blown.

7. Choose the Right Heater Size: If your electric heater is too small for the room you are trying to heat, you will need to choose a larger heater.

Troubleshooting Tips

  • If you have tried all of the above solutions and your electric heater is still blowing cold air, you may need to contact a qualified technician for help.
  • You can also try resetting the heater by unplugging it from the power outlet for a few minutes and then plugging it back in.
  • If you have a space heater, make sure it is placed in a safe location away from flammable objects and that the cord is not a tripping hazard.
