Why is dehumidifier blowing hot air

As earlier stated, the function of the refrigerants in the dehumidifier is to cool down the air that has been initially drawn in. What then happens when this refrigerant starts to leak is that the warm air never gets to cool. The warm air then gets hotter and hotter as it passes through the hot unit of the dehumidifier.

As it then goes out of the dehumidifier in your room, it is very easy to notice this hot air almost immediately. There is a difference between an air-conditioner and a dehumidifier with regards to how they function in the presence of airflow.

Air-conditioners become hot due to insufficient airflow to remove waste heat. While in dehumidifiers, incoming air is hotter than the outgoing one. When there is insufficient airflow, the air that surrounds the dehumidifier becomes cooler, causing an accumulation of moisture in the freezer.

The motor of the dehumidifier, on the other hand, can also start to heat if it is deprived of incoming air sufficiently.

A dirty air filter or blocked air vent could cause this occurrence. As time goes on, you will notice some leaks in your dehumidifier. Most of the time, the causes of these leaks are linked to collection tray or bucket problems. When mounting brackets and screws get lose, there will be a sound generated as the dehumidifier works.

You can stop this noise by tightening all the screw parts and other lose components — the dehumidifier should start to hum once again. Dehumidifiers can only do so much as slightly raising the room temperatures. You may not feel like the room is warmer when your dehumidifier is functioning within a smaller room.

A Dehumidifier blowing hot air can be attributed to many factors. These factors are largely due to internal faults and slightly due to what you do or not. Some of these reasons include overworking your dehumidifier, a full collection tray, broken components due to wear and tear leaking refrigerant, and lack of adequate airflow. When you investigate the reason why your dehumidifier is operating abnormally, make sure you follow all the steps highlighted in this post to get it to function properly once again.

Keep in mind that some of these signs point to the dehumidifier being broken beyond repair:. When a dehumidifier is running, you will usually hear a steady hum of the compressor. Some dehumidifiers are also quieter than others. However, in cases where the hum randomly stops, it most likely means you are having a problem with the humidity sensor or the circuit board.

This is usually due to excessive moisture due to condensation inside the unit. To verify this, check if the display is behaving normally.

If the display is flickering, the most likely cause is the circuit board. However, if the display is showing the correct humidity, then the humidity sensor is not damaged. If you notice intermittent buzzing or clicking for a couple of seconds every few minutes, you will most likely have a faulty compressor or dedicated compressor components failing.

Dehumidifiers usually have a thermostat on top of the compressor which turns off the unit when it turns too hot; if this sensor goes haywire, this may cause the unit continue running and build up heat. Besides the thermostat, any other electronic components in the unit, such as capacitors, can get busted out of nowhere. However, if you do have an ohmmeter, carefully test one component at a time until you suss out the cause, such as in this video.

The float switch and the bucket switch are two examples. These switches are safety features and are designed to be very sensitive. Small dehumidifiers have a reservoir where the water that they draw from the air collects. Once the reservoir is full, the dehumidifier stops drawing moisture from the air. The unit keeps moving the air but since it does not remove humidity, the air remains hot instead of cooling down some. The solution — Just empty the reservoir so that the dehumidifier can start removing moisture and cooling the indoor air again.

You will be happy to know that you can use dehumidifier water on your plants. You should check the time that the manufacturer says a dehumidifier should run. If it has exceeded those hours, the dehumidifier compressor goes hot and it starts blowing hot air back into the room. To know whether the dehumidifier has been running too long, touch it.

If it is hot, you need to turn it off and give it some time to cool down. The solution — To know whether the dehumidifier heats up room because it has been running too long, touch it. If it feels too hot, switch it off for sometime, until it cools down. When your dehumidifier coils are too dirty, they could release too much heat into the room. Thus, you need to check them! Think, when did you last clean the dehumidifier coils? If it has been some time, well, they could be the cause for the dehumidifier blowing hot air.

There is no problem with dehumidifiers blowing warm air, but if it is too hot, check the coils. You can check the user manual that came with the appliance to know how to clean them.

It is very important that you buy the right size dehumidifier for your room. Dehumidifiers can overheat and catch fire. Do you have one? Danby or Premier. De'Longhi or SuperClima. Dehumidifiers are quite safe. Safety mechanisms have been installed to prevent water leakage or fire hazards. The main concern that you have to worry about is the humidity getting to high or too low in your home.

Why is my dehumidifier blowing hot air? Category: home and garden home appliances. A dehumidifier blowing hot air is not a sign of malfunction. Dehumidifiers work by drawing in air and removing the moisture in it before releasing it back out. Heat is naturally produced and constantly radiates out as the unit draws works to lower the humidity in your surroundings.

Will a dehumidifier work in a cold room? Can a dehumidifier dehydrate you? Can a dehumidifier be too big? How much water should a dehumidifier collect in a day? Do dehumidifiers use a lot of electricity?

Should a dehumidifier run constantly? Where should you place a dehumidifier?
