If you want to keep your home at a comfortable humidity level, you need a dehumidifier. But how do you know if your dehumidifier is working properly? One way to test it is by checking the humidity sensor.
Here’s how to do that: First, find the humidistat on your dehumidifier. This is usually located on the front of the unit near the control panel.
The humidistat will have a small knob or dial that you can use to set the desired humidity level. Next, use a hygrometer to measure the actual humidity in the room where the dehumidifier is located. You can find hygrometers at most hardware stores.
Place the hygrometer in the room and wait for about an hour to get an accurate reading. Compare the reading on the hygrometer with the setting on the humidistat. If they are within about 5% of each other, then your dehumidifier’s humidity sensor is working properly.
If not, you may need to replace it.
- Turn on the dehumidifier and set it to your desired humidity level
- Place the sensor in a room with high humidity, such as a bathroom after a shower
- Observe the dehumidifier’s readings over the course of several hours
- If the dehumidifier is working correctly, you should see the humidity level decrease according to your setting

Dehumidifier Humidistat Sensor
If your home feels clammy and moist, it may be time to invest in a dehumidifier. These devices help to remove excess moisture from the air, making your home more comfortable and reducing the risk of mold and mildew growth. One important component of a dehumidifier is the humidistat sensor, which measures the relative humidity (RH) in the air and turns the device on or off as needed to maintain a desired level of RH.
There are two main types of humidistat sensors: mechanical and electronic. Mechanical sensors use a hygroscopic material that absorbs moisture from the air, causing it to change shape. This change in shape activates a switch that turns the dehumidifier on or off.
Electronic sensors use a capacitor that changes its capacitance as the RH in the air changes. This change in capacitance is used to control an electronic switch that turns the dehumidifier on or off. Humidistat sensors are typically mounted inside the dehumidifier unit, but some units have an external sensor that can be placed in different locations within your home (e.g., near a window where condensation often forms).
When choosing a dehumidifier, look for one with an adjustable humidistat so you can set it to your desired level of RH (typically between 30-50%). And be sure to check out reviews before purchasing to ensure you’re getting a quality product!

Can You Replace a Sensor on a Dehumidifier?
A dehumidifier is a household appliance that reduces the level of humidity in the air, typically for health or comfort reasons. Dehumidifiers are sometimes used to help control mold and mildew growth indoors. Sensors are an important part of how a dehumidifier knows when to turn on and off, as well as how much moisture to remove from the air.
If your dehumidifier’s sensor isn’t working properly, it can cause the unit to run too often or not long enough, which can waste energy and money. Luckily, you can replace a sensor on a dehumidifier relatively easily. To start, you’ll need to purchase a replacement sensor for your specific model of dehumidifier.
Once you have the new sensor, simply remove the old one by unscrewing it or popping it out (depending on your model). Then, install the new sensor in its place and screw it in or snap it into place. Once the new sensor is installed, power on your dehumidifier and test it out to make sure it’s working properly.
That’s all there is to replacing a sensor on a dehumidifier!
How Do You Bypass a Humidity Sensor?
A humidistat, or humidity sensor, is used to regulate the level of humidity in a space. It is often used in conjunction with a dehumidifier or humidifier to maintain the desired level of humidity. The humidistat has a sensing element that measures the amount of water vapor present in the air and sends a signal to the control unit.
The control unit then turns the dehumidifier or humidifier on or off as needed to maintain the desired level of humidity. There are two main types of humidistats: mechanical and electronic. Mechanical humidistats use a bimetallic strip that bends when it comes into contact with moisture.
This movement activates a switch that turns the dehumidifier or humidifier on or off. Electronic humidistats use a capacitor that changes its capacitance when exposed to moisture. This change in capacitance is used to trigger a switch that turns the dehumidifier or humidifier on or off.
Humidistats can be either standalone units or integrated into other devices such as thermostats, HVAC controllers, and whole-house fans. You can bypass a humidity sensor by simply disconnecting it from the power source. However, this will cause your dehumidifier or humidifier to run continuously, which can waste energy and lead to excessive moisture levels in your space.
It is best to only bypass your humidity sensor if absolutely necessary and for only a short period of time.
How Do I Know If My Dehumidifier Compressor is Working?
If you’re wondering whether or not your dehumidifier’s compressor is working, there are a few things you can check. First, take a look at the unit itself. If the compressor is running, you should see and feel it vibrating.
Additionally, you can listen for a humming noise coming from the unit. If everything looks and sounds normal with the compressor, the next thing to do is check the air intake and exhaust vents. These should be clear of any obstructions.
If they’re blocked, it could prevent air from flowing properly through the unit, which would in turn prevent the compressor from working properly. Finally, check your home’s power supply. Make sure that all breakers are turned on and that there’s no damage to any of the cords or plugs.
If everything seems to be in working order but your compressor still isn’t running, contact a professional for help troubleshooting the issue.
Conclusion
If you want to test your dehumidifier’s humidity sensor, there are a few things you can do. First, make sure the unit is turned off and unplugged. Then, remove the filter and locate the sensor.
