How to Fix Fan Heater Blowing Cold Air

Why Fan Heater Blowing Cold Air?

There are a few possible reasons your fan heater might be blowing cold air. One common issue is that the fan heater might not be properly plugged in. Make sure that the fan heater is plugged into an outlet and that the plug is fully inserted into the outlet.

Another possible problem could be a clogged filter. If the filter is clogged, it will prevent the fan heater from drawing in enough air, which will cause it to blow cold air instead of heat. Unplug the fan heater and remove the filter from the unit to clean the filter. Rinse the filter off in warm water and allow it to dry completely before reinserting it into the fan heater.

Things You’ll Need

In addition to the tips we’ve already mentioned, here are a few things you’ll need to fix your fan heater blowing cold air:

  • Phillips head screwdriver
  • Flathead screwdriver
  • Socket wrench
  • Clean cloth
  • Vacuum cleaner
  • Fan Heater
  • Plug
  • Filter
  • Pliers

How to Fix Fan Heater Blowing Cold Air Step by Step Guide

Step 1: Check the Thermostat

AC is one of the most common causes of a fan heater blowing cold air. To check the thermostat, locate the switch on the heater and set it to “high.” If the fan starts blowing warm air, the problem is with the thermostat, which will need to be replaced.

Step 2: Check the Fuse

A blown fuse is a common problem with fan heaters. To check the fuse, find the fuse box and take off the cover. The fuse box will have a label that says which circuit it controls. If the fan heater is on a different circuit than other appliances in your home, then the fuse has probably blown. Put in a new fuse and test the fan heater.

Step 3: Clean the Fan Heater

A dirt and dust build-up can also cause a fan heater to blow cold air. To clean the fan heater, locate the fan guard and remove it. Use a vacuum cleaner to clean all of the dirt and dust from the fan and the surrounding area. Replace the fan guard and test the fan heater.

Step 4: Check the Air Filter

If the fan heater is blowing cold air, it may be because the air filter is dirty. To check the air filter, find the cover that is covering it and take it off. The air filter will be inside of the cover. Clean the air filter with a vacuum cleaner or a brush and then put the cover back on. Test the fan heater.

Step 5: Ductwork Issues

If you’ve checked all of the above and your fan heater is still blowing cold air, your ductwork may have issues. This is a more complicated fix and may require the help of a professional. Contact your local HVAC technician to get help diagnosing and fixing the issue.

Step 6: Heat Sensor Not Working

If your fan heater has a built-in heat sensor and it’s not working correctly, the unit may not be able to produce heat. This is another issue that may require the help of a professional to fix.

Step 7: Contractor Coil Issues

If your fan heater is not working properly, it may be because the contactor coil is dirty or clogged. To clean the coil, you need to remove the front cover of the fan heater and use a brush to clean it off.

Step 8: Replace Fan Heater

If all of the previous steps have been checked and your fan heater is still not blowing hot air, it may be time to replace the unit. This is a more expensive option, but it may be necessary if the heater is old or has been damaged. Again, be sure to consult with a professional before making decisions about replacing.

Why Does An Electric Fan Heater Stop Blowing Hot Air?

The electric fan heater has a tank of oil that heats up and blows hot air. When the tank is empty, the fan heater stops working.

Some other reasons why an electric fan heater stop blowing hot air:

Thermostat Is Stuck Below Room Temperature

If the thermostat is stuck below room temperature, you may need to replace it. To do this, unscrew the old thermostat and replace it with a new one. Make sure that the new thermostat is compatible with your heater. If your heater is still not working after replacing the thermostat, there may be a problem with the heating element.

The heating element is the part of the heater that actually produces the heat. To test the heating element, use a multimeter to test for continuity. If the heating element is not working, it will need to be replaced.

Clogged Air Intake

If your fan heater is blowing cold air, it may be due to a clogged air intake. Unplug the heater and remove the screws that hold the cover in place to clear the air intake. Remove the cover and remove any debris blocking the air intake. Replace the cover and screws and plug in the heater.

Clear the Air Intake

Clogged Air Outlet

One common problem with fan heaters is that the air outlet can become clogged with dust and other debris. If this happens, the heater will not be able to produce heat properly. However, there are a few things you can do to try to fix this problem:

  • Try cleaning the air outlet with a vacuum cleaner or a piece of cloth.
  • If the air outlet is clogged with dust, try blowing into it to dislodge the dust.
  • If the air outlet is clogged with other debris, try using a toothpick or a needle to remove the debris.

Loose Wiring

One possible reason your fan heater may be blowing cold air is that there is a loose wire. This can easily be fixed by checking the wiring and ensuring that all connections are tight. If you find any loose wires, twist them together until they are tight.

Broken Heating Element

If your fan heater is blowing cold air, the most likely problem is a broken heating element. To fix this, you’ll need to replace the heating element.

First, unplug the fan heater and remove it from its location to replace the heating element. Next, remove the cover of the fan heater and locate the heating element. The heating element will be located near the top of the fan heater.

Once you’ve located the heating element, remove it by unscrewing it from its housing. Be careful not to touch the wires or terminals on the heating element. Once you’ve removed the old heating element, replace it with a new one and screw it back into place.

Keeping The Receipts

When you make a purchase, it’s important to keep the receipt. Most stores have a policy where you can return or exchange the item within a certain number of days (usually 14). However, if you don’t have the receipt, they may not be able to help you.

Keep the Receipt

Keep your receipts in a safe place, like a folder or binder. That way, you’ll always have them when you need them. Keep reading for more information about how to fix fan heater blowing cold air.
