If you purchased a Whirlpool dehumidifier, you know it can effectively maintain humidity levels. However, if you notice problems after consistent use, it is best to address them immediately. To do that, you must first learn and understand issues with the device.

The common Whirlpool dehumidifier problems can be as simple as a full tank or dirty air filter. However, a malfunctioning machine can also be a result of damaged fans or an overloaded compressor.

Whirlpool dehumidifiers generally have a good reputation, but all devices eventually need maintenance.

This article will cover the most common issues you might encounter with a Whirpool dehumidifier. We will also teach you basic troubleshooting to ensure your room has optimal humidity levels. But first, let us teach you the basic definition and functions of a Whirlpool dehumidifier. 

What Is A Whirlpool Dehumidifier?

A Whirlpool dehumidifier is a portable device designed to reduce humidity levels in your home. It has a built-in refrigeration system that cools air and condenses moisture before draining water through a hose. It also uses a fan motor to pull in air from the surrounding room and pass it toward cold coils. These evaporator coils transform the gas into a liquid, which drips into a collection container.

By removing excess moisture, a Whirlpool dehumidifier can prevent mold and mildew growth in your home. It also eliminates allergens and ensures healthy air blowing in your home. It can even preserve the condition of your belongings sensitive to moisture, such as furniture and books.

Plus, Whirlpool dehumidifiers are available in various capacities and sizes. Feel free to choose the right model based on the size of the room you want to dehumidify.

Finally, Whirlpool is an established brand that manufactures dehumidifiers and other household appliances. Their products can last for years to come with proper care and maintenance. If you want to know which models are the most reliable, check out our Whirlpool dehumidifier reviews here.

What Are Common Whirlpool Dehumidifier Problems?

Although Whirlpool dehumidifiers are reliable, they can still face several issues. From the device not turning on to error codes, below are common Whirlpool dehumidifier problems.

Full Tank or Wrong Container Placement

Most modern dehumidifiers have an automatic shut-off switch that turns off the machine once the collection tank is full. Depending on the model you own, it can drain water automatically or manually.

If it is a manual-operated dehumidifier, you must empty the container tank yourself. Remove it from the unit and dispose of the water. Once empty, you can put the container back into the dehumidifier, and it will work again.

Also, make sure to reinsert the water collection tank properly. If not, the Whirlpool dehumidifier activates the safety switch to prevent operation until the container is properly secured. 

Dirty Air Filter

Dirty Air Filter

A dehumidifier uses an air filter to clean the air before entering the condenser coils. This filter can accumulate dust and dirt over the years because of constant use. A clogged air filter can stop the dehumidifier from working properly, reducing airflow. 

Regularly clean the air filter of your dehumidifier to ensure it functions correctly. Check your product manual to access the filter compartment. Remove it from its housing and clean it using a soft-bristled brush or vacuum. You can also rinse it out with water. Let the filter dry before reinserting it.

Frozen Coils

Low airflow can also be a result of a frozen evaporator coil.

As briefly mentioned above, a dehumidifier removes excess moisture by turning gas into a liquid. The gas flows into the evaporator coils. Under normal conditions, the air condenses and drips down to a collection tank. But sometimes, the moisture can become frost and prevent the dehumidifier from working properly.

To fix a frozen evaporator coil, you just need to wait until the ice melts. Unplug the Whirpool dehumidifier from the power cord and leave it alone for a few hours. After melting the ice, you can turn on the unit again.

If this problem arises several times, try using your humidifier in temperature-regulated rooms. If that did not fix the issue at all, then the frost-sensing element is probably malfunctioning. You may need to replace it, which is easier said than done.

Damaged Fan Blades or Fan Motor

Besides the tank, filter, and evaporator coil, the fan in a dehumidifier can also malfunction. It can stop air coming, which affects the entire dehumidifying process.

To check if the fan is indeed the culprit, unplug the Whirlpool dehumidifier and remove the front cover. Turn the fan blade by hand to determine whether accumulated debris or a broken blade prevents it from working properly. Also, check the blower wheel to see if it is properly connected to the motor shaft.

If it is debris, you can simply clean it up. Wear a mask to avoid inhaling the dust and other particles.

If the problem is a broken blade, you can order a new one. Look up your model number to ensure the repair parts are compatible with the device. Then, follow the manufacturer’s instructions on handling and installing the new blade.

However, a broken fan motor might be at fault if the fan still malfunctions after cleaning. Resolving it is more complicated, so it is best to hire a professional technician to replace it. Or consider purchasing a new unit because it might be more cost-effective.

Broken Capacitor

If you cleaned the filter and fan or defrosted the coils but still facing trouble with the dehumidifier, the capacitor might be the culprit. 

A broken capacitor is unable to power the compressor and the fan motor. It might be able to turn the fan on, but the motor will eventually overheat.

To fix the problem, unplug and disassemble the dehumidifier. Remove the panel cover and the filter, then undo several screws to locate the capacitor. Test its continuity (ohms) with a multimeter. If it does not have continuity, you must replace the capacitor with another one.

Overloaded or Faulty Compressor

The compressor is the core of a dehumidifier. When its functionality is compromised, it cannot cool and supply water to the coils and collection tank.

A tell-tale sign of a faulty compressor is unusual and extremely loud sounds. It is normal for a dehumidifier to produce noise while working. But if the sound is overly loud, it might be time to replace the unit.

A compressor circuit can also overheat due to frost buildup. Consult the product manual for the location of the overload switch. Flip this button to reset the compressor after the frost has melted. You can also perform a voltage test with a multi-meter for troubleshooting. If these do not fix the problem, consider getting a replacement.

However, buying a new dehumidifier might be more cost-effective, depending on your model. So consider going that route as well. 

Malfunctioning Electrical Parts Or Connections

If you use the wrong plug or electrical connections, the internal wiring and electrical parts of the dehumidifier can go bad.

However, it is not as easy to test the electrical components of a Whirlpool dehumidifier for damages. You better leave it with professional electricians to look at your appliance and confirm if it is an overload device. Or, if your unit is still under warranty, go ahead and call the manufacturer. 

Defective Electronic Control Board

A large power surge can fry the circuit board of the dehumidifier. This component is responsible for regulating moisture levels in the air. If it does not function properly, the dehumidifier will not run. 

Similar to malfunctioning electrical parts, a defective electronic control board is dangerous to fix on your own, especially if you do not have experience. Go to an appliance repair shop or contact a technician for custom troubleshooting help. 

Also, weigh the cost of the repairs against the cost of buying a new dehumidifier. You will find a new circuit board is not that expensive, but you may end up spending more on the cost of labor.

Whirlpool Dehumidifier Troubleshooting: How to Fix a Malfunctioning HVAC System?

Now that you know the common dehumidifier problems, the big question is: how to fix them?

Below, we will share basic troubleshooting tips you can follow to make your appliance work again.

First, if the dehumidifier is not turning on, ensure you are using a working electrical outlet. Inspect the circuit breaker or fuse box if something has tripped or blown. If so, contact an electrician right away.

To fix water leakage, insert the water collection tank properly. Always check the drainage hose and ensure it is not blocked.

For excessive noise, you want to place your dehumidifier on a stable and level surface. Regularly clean the filter and fan to prevent clogging.
