Electric fan heater not blowing warm air? here’s why and how to fix it
What To Know
- The air filter in an electric fan heater traps dust and debris to prevent them from entering the heating element.
- A malfunctioning thermostat may not accurately sense the temperature of the room, causing the heater to turn off prematurely or fail to turn on at all.
- What should I do if my electric fan heater is blowing cold air and I have tried all the troubleshooting steps.
Electric fan heaters are a convenient and efficient way to warm up a room. However, when they start blowing cold air, it can be frustrating and uncomfortable. There are several reasons why this might happen. In this blog post, we will explore the most common causes of electric fan heaters blowing cold air and provide step-by-step instructions on how to fix them.
Causes of Electric Fan Heater Blowing Cold Air
1. Overheating:
Electric fan heaters have a built-in thermostat that turns off the heater when it reaches a certain temperature. If the heater overheats, the thermostat may trip and shut off the heater prematurely, resulting in cold air being blown out.
2. Clogged Air Filter:
The air filter in an electric fan heater traps dust and debris to prevent them from entering the heating element. A clogged air filter can restrict airflow, causing the heater to overheat and trip the thermostat.
3. Faulty Heating Element:
The heating element is the core component of an electric fan heater. If the heating element is damaged or faulty, it may not produce enough heat to warm the air.
4. Loose Electrical Connections:
Loose electrical connections can disrupt the flow of electricity to the heating element, causing the heater to blow cold air.
5. Thermostat Malfunction:
A malfunctioning thermostat may not accurately sense the temperature of the room, causing the heater to turn off prematurely or fail to turn on at all.
Troubleshooting and Fixing Electric Fan Heater Blowing Cold Air
1. Check for Overheating:
Unplug the heater and allow it to cool down completely. Check if the heater is placed too close to flammable materials or if the air vents are blocked.
2. Clean or Replace Air Filter:
Locate the air filter and remove it. Clean the filter with a vacuum cleaner or replace it with a new one.
3. Inspect Heating Element:
Unplug the heater and remove the heating element. Visually inspect the heating element for any damage or corrosion. If the heating element is damaged, it will need to be replaced.
4. Tighten Electrical Connections:
Unplug the heater and check all electrical connections. Ensure that the wires are securely fastened and that there are no loose connections.
5. Reset Thermostat:
Locate the thermostat and press the reset button. This will reset the thermostat and potentially resolve any malfunctioning issues.
Additional Tips
- Use the heater in a well-ventilated area: This will prevent the heater from overheating and tripping the thermostat.
- Keep the heater away from flammable materials: This will reduce the risk of fire.
- Do not cover the heater: Covering the heater can restrict airflow and cause it to overheat.
- Unplug the heater when not in use: This will prevent the heater from drawing power unnecessarily and reduce the risk of electrical accidents.
