2. Temperature and Humidity Solutions
Optimal Temperature Range
Most dehumidifiers are designed to operate efficiently in a specific temperature range, usually between 60°F and 110°F.
When room temperatures fall below 60°F, it becomes difficult for your dehumidifier to collect water, as the coils may freeze.
To ensure your dehumidifier functions properly, maintain the temperature within this range.
If you live in an area with cooler temperatures, consider purchasing a dehumidifier designed for low-temperature operation.
Setting the Right Humidity Level
The effectiveness of your dehumidifier isn’t just contingent upon the temperature; it also relies on the relative humidity in your space.
In winter or arid regions, indoor humidity levels can be quite low, which may cause your dehumidifier to stop working quickly if there isn’t enough moisture to extract.
To determine your space’s ideal humidity level, note how damp the area feels or use a hygrometer to measure the relative humidity.
The recommended indoor humidity level is generally between 30% and 50%. You may not need to run your dehumidifier if the humidity is already within this range.
Adjust your dehumidifier’s settings to achieve the desired humidity level if it’s higher than this range.
Remember, using the right dehumidifier size is crucial for effective moisture removal.
If you use a small dehumidifier in a large space, such as a basement, you may need help to keep up with the humidity demands.
Make sure to choose a dehumidifier designed for your space’s size and humidity levels for optimal performance.

3. Component Repairs and Replacements
When your dehumidifier stops collecting water, the issue might be with the compressor. This crucial component may only run if the room temperature is at most 65 degrees Fahrenheit.
Check to make sure the compressor is functioning properly.
If not, consider repairing or replacing the compressor to have your dehumidifier back up and running efficiently.
Capacitors and Overloads
Remember the capacitors and overloads that help run the compressor. Your dehumidifier might not collect water due to a fault in these components.
Test the capacitor to ensure it’s providing the right amount of electricity. If the overload is faulty, it won’t be able to protect the compressor.
Replace the capacitor or overload, if necessary, to fix the problem.
Fan Motors and Blower Wheels
Your dehumidifier may not be collecting water because of issues with the fan motor or blower wheel.
Examine the motor to ensure it’s functioning correctly; if not, it might need a repair or replacement.
Check if the blower wheel is clean and functioning properly, and ensure it’s firmly connected to the motor shaft.
Control Boards and Sensors
Electronic control boards and sensors help your dehumidifier operate smoothly.
A damaged control board might not send the right signal to the compressor or fan motor, causing the dehumidifier to malfunction.
Carefully inspect the PCB assembly and check for any damaged components. Test the humidity sensors to ensure they accurately read the room’s moisture levels.
Look for any signs of damage and consider replacing the control board or sensors if necessary.
Float Switches and Drain Pipes
Your dehumidifier might need to be collecting water due to float switch or drain pipe issues. The float switch signals the dehumidifier to stop collecting water when the tank is full.
If the float switch is stuck, it can be reset by tapping it gently.
Check the drain pipes for any clogs or obstructions, as this could prevent your dehumidifier from properly collecting water.
By addressing the possible component issues listed above, you can run your dehumidifier efficiently and collect water again.
