why does my frigidaire dehumidifier freeze up

by Prof. Frankie Wuckert Published 3 years ago Updated 2 years ago

If the room temperature is below 65 degrees Fahrenheit, the dehumidifier coils will frost up. If the temperature in your home regularly drops below 65 degrees, you will need to obtain a model that is specifically designated for lower temperature operation.

Why does my fridge freezer keep blowing the fuse?

Your fridge’s fuse can blow due to any the following reasons:

  • A power surge causes a temporary increase in the electricity travelling through the circuit. Some fuses are designed to withstand short bursts of high electricity, while others are not.
  • Overtime, the fuse itself may simply weaken.
  • Circuit overload caused by multiple appliances plugged into in the same power source. ...

What does it mean when a dehumidifier freezes up?

Room Temperature One of the most common reasons for your dehumidifier freezing up is quite simply the temperature of the room it is in. Most dehumidifiers work perfectly well at 65 degrees or above but if the air temperature is any lower than this you could see your dehumidifier icing up and this will stop it working.

What causes dehumidifier coils to ice up?

The humidistat electrical contacts power the compressor circuit to cycle on. If the humidistat is not reading the humidity correctly, the compressor will stay on which can cause the coils to freeze up. The electrical contacts can also become welded shut, leading to the same problem.

How do I clean the coils on my dehumidifier?

Gently vacuum off the top layer of dust and grime or scrape it off with your hand. Use a soft-bristled brush or cloth to clean the coils with a spray detergent or mixture of vinegar and water. Rinse off any residue. Make sure you let the coils completely dry before using your dehumidifier again.Oct 14, 2021

Should you run a dehumidifier in winter?

How to prevent dehumidifier from freezing?

1. Blower wheel or Fan blade. In order to prevent frost from building up or freezing, there must be a sufficient amount of air blowing in and out of the dehumidifier’s evaporator coil and condenser coils. If you have made sure that the filter is clean, yet there is no air coming out through the grille area, it is then time to remove ...

Why is my dehumidifier icing up?

Temperature and Airflow. When there is a problem with temperature and unit air flow system, your dehumidifier will not work properly, it will lead to ice building up in its coils and you even any other form of serious damage.

What is a dehumidifier unit?

A typical dehumidifier unit consists of cold evaporator coils, warm condenser coils, a fan, and a reservoir or drain. Every dehumidifier model that has been making recent moves into the market also has a humidistat. A humidistat is similar in function to a thermostat.

What does a humidistat do?

The humidistat carries out the function of tracking the humidity in the room; the electric contacts of the humidistat are designed to turn on the device’s compressor. If the humidistat is not working, the compressor will also malfunction and promote coil freezing.

What happens if your dehumidifier is not working?

If your dehumidifier is not functioning correctly and is icing u, these water droplets will not reach the reservoir, rather they will generate a cold breeze. When the room temperature sies, the ice will melt, and the reservoir will overflow. A sign that your dehumidifier is in need of repair.

What does it mean when your air compressor is unable to pull water out of the air?

If you have verified that the ambient room temperature is above 65 degrees Fahrenheit, but still the device is unable to pull water from the air; it means you are dealing with a faulty compressor. The overload device in the compressor circuit might be damaged, causing the compressor to also fail.

What to do if there is no air coming out of grille?

If you have made sure that the filter is clean, yet there is no air coming out through the grille area, it is then time to remove the cover and check the fan area. The blower wheel and the fan blade are responsible to prevent freezing and manage the air flow.

What Causes a Dehumidifier to Freeze up? (Ice Up)

It may seem counterintuitive, but the dehumidifier that seems to be working has started icing up. What can cause this? There are a number of different factors which can lead to your dehumidifier icing up:

How to Prevent A Dehumidifier Freezing Up? (Stop from Icing Up)

So now that you know how to fix it when your dehumidifier freezing up, the next step is to prevent this problem from happening in the first place.

What Can You Do to Stop it?

The first thing you should do is check the air temperature setting on your dehumidifier.

How to Repair a Dehumidifier with Coils That are Icing Up? (Freezing)

Dehumidifiers are designed to get rid of excess moisture in the air. They do this by collecting water from the air and then drying it out so that it has a lower relative humidity than before. But if your coils are icing up, there's likely something wrong with your unit.

Dehumidifier Icing Up FAQ

If the airflow is restricted on your Kenmore dehumidifier, the evaporator coils will get too cold. As humid air passes over the evaporator coils, it’ll condense and freeze onto them. Eventually, the entire evaporator coil assembly could ice up from this and frost over.

Why does my dehumidifier freeze up?

Here are the few common causes: 1. Running Below 65°F Temperature. The most common cause why dehumidifiers freeze up is because the room is simply too cold. Even if the machine can operate at a low temperature, it is typically cap at 65°F degrees. Running below the recommended temperature will cause ice to build up on the condenser coils.

Why is my dehumidifier icing?

If the dehumidifier is spotless, running smoothly, yet icing still occurs, it is likely due to mechanical failure or electrical faults.

What is humidistat in a dehumidifier?

Similar to a thermostat, a humidistat is part of the electronic control module that monitors the ambient relative humidity level. It is very important as the dehumidifier anti-frost/ auto-deicing mode relies on the sensor signals to shut off the compressor to prevent an ice build-up.

How does a dehumidifier work?

The dehumidifier begins by pulling damp air into the ventilation and passes to the evaporator coils for condensation. Water droplets will be drained out and stored in the reservoir or pump straight out via a hose. Dry air will then passes to the hot condenser coils and release out as mist to complete the cycle.

What causes ice build up on a dehumidifier coil?

Running below the recommended temperature will cause ice to build up on the condenser coils. The only saving grace is the auto-frost mode feature that will shut down the compressor when the dehumidifier coils become too cold. 2. Faulty Humidity Sensor.

Why is my dehumidifier not making a whirring noise?

If there is no whirring noise coming from the dehumidifier, a defective fan motor or blower wheel could be the blame. Fan motor/ blower wheel is vital component parts that facilitate airflow circulation and prevent the condenser coils from freezing up. A visibly clean air filter is a good sign of a broken fan motor as there is no air flowing through the grille. Additionally, dust, dirt, or debris could also impede the fan from spinning smoothly. This could result in broken or loose fan blades that further restrict the airflow output.

Where is the filter located on a dehumidifier?

The filter is typically located behind the grille of a dehumidifier. Lightly vacuuming the surface of the filter to remove the trapped particles without damaging it. Most filters also can be soaked and washed in warm water to remove stubborn dirt particles.

Why is my dehumidifier freezing up?

If the coils in your dehumidifier are freezing up, but the temperature in the room is over 65°, you may have a problem with your blower wheel/fan blade. These 2 parts control the flow of air that is required to prevent the condenser coils from freezing up. If you have cleaned the air filter, but there is no air flowing through the grill, you can remove the fan cover so that you can inspect the coils.

What causes a dehumidifier to freeze?

The electrical contacts of the humidistat cause the compressor of your dehumidifier to turn on. If the humidista t is not functioning properly, your compressor stays on, which causes the coils to freeze up.
