Why Is My Dehumidifier Blowing Out Hot Air

Why Is My Dehumidifier Blowing Out Hot Air

You’ve got a dehumidifier, and it’s working fine. But then one day, you open it up and see that your air is blowing out hot instead of cold. Why? Is this normal? And if so, what can I do to fix it?

Dehumidifier Blowing Out Hot Air

The problem is likely one of the following:

  • The dehumidifier is not working properly. Check for any obvious signs of damage, like a broken part or loose connection. If you see something wrong but cannot fix it yourself (for example, if there’s no power source nearby), contact an electrician or technician for assistance.
  • The dehumidifier has a dirty filter that needs cleaning with distilled water and paper towels or cloths soaked in vinegar (1/4 cup per gallon). Make sure to clean out all of the debris from inside your unit before trying again!

Dehumidifier Blows Cold Air

If your dehumidifier is blowing out cold air, it means that it’s working as intended. If your dehumidifier is blowing out hot air, however, there may be something wrong with the unit itself—it could be dirty or clogged with dust.

You should contact the manufacturer if this happens and they will send you a new one (or parts if necessary). This can take up to two weeks but sometimes happens right away!

If your dehumidifier is blowing out hot air, it’s probably not working

If you’re having trouble with your dehumidifier and it’s blowing out hot air, there are a few things to keep in mind:

  • If your dehumidifier is blowing cold air, then it’s probably not working properly. This can happen if the fan inside of the unit has broken or if there was something wrong with its construction (like a faulty switch).
  • A broken or faulty dehumidifier can be dangerous due to the large amount of electricity being used by them when they’re turned on. This could cause fires if wiring gets damaged while running at full power! It would also be wise to check over all electrical components before using it again after an outage because any issues could lead to overheating issues later on down road too so make sure everything checks out fine before plugging back into wall socket again (and don’t forget those smoke detectors!).

Check the Drain

The first thing you should do is check your dehumidifier’s drain. You may find that it’s blocked, or that other objects are getting in there and blocking it up. If your drain hose isn’t long enough, try cutting off some of its length with a pair of scissors until it reaches the point where you want to open up a hole for drainage.

You should also make sure there aren’t any kinks or clogs in the drain hose itself (if there are, they could prevent air from flowing out of your appliance). Finally, make sure that your house isn’t connected directly to an old-style cold water pipe that runs under floors and walls; this can cause condensation buildup when there’s no warm water present nearby (and therefore no evaporation).

Heighten Your Dehumidifier

If you have a dehumidifier that’s blowing out hot air, the best thing to do is elevate it. This will help keep it cooler for longer, and keep any condensation from building up inside the unit.

  • Put your dehumidifier on a table or shelf (if possible).
  • If that’s not an option, try placing it on a chair or stool—it’ll still work well as long as its top is at least 2 feet off the ground.
  • You can also use platforms or other types of stands that are meant specifically for holding electronic devices upright while they’re charging;these should come in handy if you don’t have any space under your current setup!

Mind the House Temperature

  • Keep the house temperature between 65 and 75 degrees.
  • Keep the dehumidifier away from heat sources like radiators, stoves and fireplaces.
  • Make sure you have good ventilation in your home to ensure that hot air doesn’t get trapped inside when it’s humid outside.

Check the Fan Functionality

First, check the fan functionality. You should be able to see if the fan is working and running at the right speed. If your dehumidifier is blowing out hot air, then it’s likely that there are some issues with how your unit operates.

Here are some things to look for:

  • Is the fan blade spinning? If not, then you might have clogged filters or broken blades in need of replacement. If so, then these items can also cause problems with overheating and blowing out cold air instead of warm (or even hot).
  • Are all four of its blades bent or missing? A bent blade could break easily when spun around inside a cylinder; this would result in overheating as well as low humidity levels—both symptoms associated with an inefficient dehumidifier!

Ensure It Is a Dehumidifier, Not a Humidifier

The first thing to do is check your dehumidifier. If it’s a humidifier, you may need to replace it with a dehumidifying appliance.

If your home is wet and humid, then you’ll have to use both types of cooling systems in order for them all work properly.

Wipe and Clean the Unit Well

If your dehumidifier is blowing out hot air, it’s time to take care of it. First, wipe down the unit thoroughly with a clean cloth or paper towel. This can help prevent dust from building up and clogging up your unit.

Next, don’t use harsh chemicals on your unit—they’ll damage its exterior and could cause other problems later on! Instead of using disinfectants or bleach (which are both known for causing damaging effects over time), try baking soda or clumping agent replacement packets instead. These two methods will help keep bacteria at bay while still giving you the results you want from your machine; however, be careful not to get too close when using these products because they can burn easily if inhaled into one’s lungs!

Another way that people often try cleaning their dehumidifiers without success is by putting them through dishwashers or microwaves without first checking whether those methods work either way; we recommend against doing so because even though these appliances do look pretty cool when they’re done drying off after washing day–and especially during winter months where there isn’t much else going on around here–they still need protection against corrosion due mainly but not exclusively due largely because moisture build-up inside areas such as electrical components within these types.”


If your dehumidifier is blowing out hot air, it’s probably not working. There are several reasons that this could be happening:
The unit may be clogged with dust or dirt. Take the time to remove this buildup by vacuuming the interior and exterior of your unit regularly.
The fan inside the housing might have stopped spinning properly or become damaged over time. If this happens there isn’t much that can be done except replace it! You can find replacement parts online at places like Amazon or eBay if needed; however they won’t come cheap so make sure you check all costs before making any purchases!
