It’s rather common for heaters to break down. However, the failure of heaters and the blowing of chilly air on a bitterly cold day are two distinct events. Things get serious when it comes to electric heaters that blow chilly air. It’s as if the heater just had one task and failed miserably. Anyway, Why Is My Portable Electric Fan Heater Blows Cold Air?
Allow time for the heater to warm up before troubleshooting the thermostat. Any issues? Then search for unclean filters to clean out and leaky ducts to repair. Is the frigid air still blowing?
Try replacing them if something went wrong with your heat sensors or contractor coils. This was only an overview; if you want to fix the problem, read our article because we detail the options.
Room heaters are incredibly important gadgets during the winter since they keep us warm and cozy.
These appliances should run smoothly throughout the cold season and should not cause any issues if properly maintained. However, now and then, you may notice some issues: the heater not blowing hot air.
Why Is My Portable Electric Fan Heater Blows Cold Air? Reasons
Your portable electric fan heater may be blowing cold air due to several reasons:
- Thermostat Setting: The thermostat might be set too low, preventing the heater from warming up.
- Heating Element Failure: The heating element could be malfunctioning or broken.
- Overheating: Some heaters have a safety feature that blows cold air when they overheat.
- Internal Fuse: A blown fuse can prevent the heating element from receiving power.
- Airflow Blockage: Dust or debris might be blocking the heater’s intake, affecting its performance.
It’s recommended to check the thermostat setting, ensure proper ventilation, and consult the user manual or a professional if the problem persists.
Dirty Filters
The majority of people do not consider cleaning their heaters. Electric heaters frequently blow chilly air when their filters are blocked, so it’s the first thing you should examine.
To begin, switch off your heater and inspect the filters. If your heater’s filters are caked with dust, this is most likely the cause of the problem.
Clogged vents reduce ventilation and cause coils to freeze, obstructing airflow even further. As a result, the air coming out of your electric heater is frigid. Change your filters first, and if that doesn’t work, try one of the other options listed below.
Thermostat Settings
Most electric heaters have two settings, so check your thermostat if your heater blows cold and warm air at various times.
Naturally, all heaters utilize a fan to circulate air, but if your fan is set to ‘on’ all day, it explains why your heater appears to be broken.
For the fan to emit warm air, the furnace inside the apparatus must be heated. The air being pushed outside cannot be heated if the furnace is cold.
Set your blower to ‘auto’ to ensure that your fan only operates when the furnace is hot. Of course, reading the instruction manual is the simplest way to solve this problem.
The handbook will explain adjusting the fan speed without impacting the other settings. Wait a few minutes after turning on the heater to see if it’s still blowing chilly air, as electric furnaces take time to warm up.
Furnace Problems
Electric heaters operate on the same principles as any other machine. An overheated furnace can create comparable outcomes to your smartphone’s battery heating up and causing phone troubles.
It’s good to check if your heater is working properly and if it stops blowing after a short time or starts releasing cold air.
Engineers embedded automatic limit switches that turn the heat-generating furnace off to prevent the heater from malfunctioning completely.
If your heater isn’t producing any heat, it’s advisable to have it serviced by professionals, particularly if replacing the filters isn’t working.
Ductwork
This issue does not necessitate dismantling your heater or its electric panel. If your home’s ducts are leaking, your indoor space’s heating may be impaired.
Even if the heater is switched on, the cold air inside the vents will automatically make the room colder. The only method to address this is to ensure that all of your vents are completely closed.
Why Is My Fan Heater Blowing Cold Air?
If your electric wall heater’s fan is running but it’s not emitting warm air, there could be several reasons:
- Manual Reset has Tripped: The heater circuit might have been interrupted due to excessive operating temperatures. This can be caused by blockages, and the heater might need cleaning.
- Thermostat Settings: If the fan switch is “on” and the thermostat setting is below the actual room temperature, the heater will blow cold air.
- Fan Dispersing Air After Shutdown: Some heaters have a timed-delay switch that operates the fan for a short time after the heating elements are turned off. This can result in cold air being blown out temporarily.
- Loose Wiring: There might be a loose wire coming from the heating elements. Ensure all connections are tight.
- Defective Heater Element: The heating element, which converts electrical energy into heat, might be faulty. If this is the case, replacement is the only option.
For minor issues like resetting the heater or tightening loose wiring, refer to the owner’s manual. For more significant problems, especially concerning the heating element, it’s recommended to consult a licensed electrician or consider replacing the heater.
Conclusion
If your heater is causing you to shiver on cold winter evenings, you should inspect it for the issues listed above in Why Is My Portable Electric Fan Heater Blows Cold Air? In most cases, heaters that generate chilly air do not require expensive repairs.
Hiring a professional can be costly, so many people save it till last. However, if you have exhausted all of your options, you should seek expert help. Working with electrical equipment can be hazardous, especially regarding hardware concerns.
