Is your dehumidifier not working properly? You rely on it to keep your home comfortable and free from excess moisture.
When it stops working right, you might notice stubborn dampness, musty smells, or even mold starting to appear. This can be frustrating and worrying. But don’t worry—you’re not alone, and fixing this problem is easier than you think. Keep reading to find out why your dehumidifier might be acting up and what you can do to get it running smoothly again.
Your home’s comfort depends on it.
Common Signs Of Malfunction
Dehumidifiers help keep your home dry and comfortable. Signs of malfunction often appear before major damage. Spotting these signs early can save time and money. Below are common signs that your dehumidifier might not work properly.
Reduced Moisture Removal
The main job of a dehumidifier is to remove moisture. If you notice dampness or high humidity levels, it might not work well. The air may feel sticky or wet even after running the machine. This is a clear sign that the dehumidifier is failing.
Unusual Noises
Strange sounds like grinding, buzzing, or rattling are warning signs. These noises often mean parts inside are loose or broken. Ignoring these sounds can lead to bigger problems or complete failure.
Water Leakage
Water should collect inside the tank, not outside. Leaks around the unit show a problem with the tank or seals. Water on the floor can damage flooring and cause mold growth. Check for leaks regularly.
Frequent Cycling
The dehumidifier should run smoothly and steadily. If it turns on and off too often, it may have a sensor or thermostat issue. Frequent cycling wastes energy and reduces effectiveness. This needs prompt attention to avoid bigger faults.

Basic Troubleshooting Steps
When a dehumidifier stops working well, simple checks can help fix the problem. Basic troubleshooting steps save time and avoid costly repairs. Follow these easy actions to find common issues and get your device running again quickly.
Check Power Supply
Make sure the dehumidifier is plugged in properly. Check the power outlet by plugging in another device. Look for any loose or damaged cords. Confirm the power switch on the dehumidifier is turned on.
Inspect Air Filters
Dirty filters block airflow and reduce performance. Remove the air filters and clean them with warm water. Let them dry completely before placing them back. Replace filters if they are torn or very worn.
Clear Drainage System
Check the drainage hose or bucket for clogs. Remove any dirt, dust, or mold buildup. Ensure the hose is not bent or kinked. Proper water flow helps the dehumidifier work efficiently.
Reset The Device
Turn off the dehumidifier and unplug it from the power source. Wait for about five minutes to let it reset. Plug it back in and switch it on. This can clear minor errors in the system.
Advanced Fixes To Try
Advanced fixes help restore your dehumidifier’s performance. These steps need more care and tools.
Try these fixes only if basic steps did not work. They dig deeper into common problems.
Examine The Humidistat
The humidistat controls moisture levels. Check if it reads humidity correctly.
A faulty humidistat stops the dehumidifier from turning on or off. Replace it if needed.
Clean The Coils
Dirty coils reduce efficiency. Clean the coils carefully with a soft brush or cloth.
Unplug the unit before cleaning. Avoid damaging the fins or wires.
Test The Compressor
The compressor pumps refrigerant to remove moisture. Listen for strange noises or no sound.
A broken compressor means the dehumidifier cannot work properly. Testing may require a professional.
Replace Faulty Components
Faulty parts like fans, sensors, or switches cause problems. Identify and replace broken parts.
Use original parts to keep the machine working well. Check the manual for part numbers.

Preventive Maintenance Tips
Keeping your dehumidifier in good shape helps it work well longer. Regular care stops common issues early. Small habits make a big difference in performance.
Check the device often. Clean parts and watch for problems. This saves time and money on repairs later.
Regular Filter Cleaning
Filters trap dust and dirt from the air. Dirty filters block airflow and reduce efficiency. Clean the filter every two weeks. Use a soft brush or wash with water. Let it dry fully before putting it back. This keeps the air clean and the machine working strong.
Proper Placement
Place the dehumidifier where air flows freely. Avoid corners or behind furniture. Keep it away from heat sources or direct sunlight. Good placement helps the machine remove moisture better. Also, leave space around it for air circulation.
Routine Drainage Checks
Check the water tank or drain hose often. Empty the tank before it gets full. Inspect the hose for clogs or leaks. Blocked drainage stops water removal and can damage the unit. Clean the drainage parts monthly for smooth operation.
Seasonal Care
Prepare the dehumidifier for changing seasons. In winter, use it less or not at all if the room is dry. In spring and summer, clean it well before use. Store it in a dry place when not needed. Seasonal care keeps the machine ready and safe year-round.
When To Call A Professional
Knowing when to call a professional for your dehumidifier saves time and effort. Some problems need expert help to fix safely and correctly. Trying to repair complex issues alone can cause more damage. Watch for signs that show you need a technician.
Persistent Issues
When your dehumidifier stops working despite cleaning and simple fixes, it signals a deeper problem. Constantly needing to reset or unplug the device is not normal. Persistent issues mean internal parts may be failing. A professional can diagnose and repair these problems efficiently.
Electrical Problems
Electrical issues can be dangerous and require a trained technician. If your dehumidifier trips breakers or won’t turn on, avoid testing electrical parts yourself. Sparks or burning smells are clear signs to stop using the unit. Experts have the right tools to handle wiring safely.
Compressor Replacement
The compressor is the heart of a dehumidifier. When it breaks, the machine stops removing moisture. Compressor repair or replacement is complex and needs special skills. A technician can check if your compressor needs fixing or replacing. Attempting this yourself can void warranties or cause more harm.
Warranty Considerations
Check your dehumidifier’s warranty before attempting repairs. Many warranties cover parts and labor for a set time. Opening the unit or fixing parts yourself might void the warranty. Calling a professional ensures repairs follow the warranty rules. This saves money and protects your investment.
Alternative Solutions For Humidity Control
Dehumidifiers can stop working properly for many reasons. While fixing the unit might take time, other ways exist to control humidity in your home. These solutions help reduce moisture and keep air fresh. Some methods work well alone, while others work better combined.
Using Fans And Ventilation
Fans help move air and reduce dampness. Opening windows allows fresh air to enter and wet air to leave. Exhaust fans in kitchens and bathrooms remove moisture quickly. Good airflow prevents mold and mildew growth. Use fans regularly to keep air dry and clean.
Houseplants For Moisture Absorption
Certain houseplants absorb moisture from the air naturally. Plants like Boston ferns and peace lilies help reduce humidity. They also improve air quality. Place plants in rooms with high moisture to balance the air. Take care of plants by watering and trimming them properly.
Sealing Leaks And Insulation
Leaks in walls and windows let humid air enter your home. Seal cracks and gaps with weather stripping or caulk. Proper insulation keeps warm, moist air outside during summer. It also stops cold air from entering in winter. Fixing leaks and adding insulation keeps humidity levels stable.
Portable Vs. Whole-home Dehumidifiers
Portable dehumidifiers work well in small areas like bedrooms or basements. They are easy to move and use less power. Whole-home dehumidifiers connect to your HVAC system. They control humidity in all rooms evenly. Choose based on your home size and humidity needs.
