What Causes the Red Light on Crane Humidifier

Red lights have been known to signify danger. So, it’s normal for you to worry about the red light on your Crane humidifier.

Contrary to what you might think, the red light on your device is just an aesthetic choice. The light’s purpose is just to provide you with valuable feedback on the current state of your device.

The red light isn’t always there. So, when it appears, it means that it has been triggered by something. So, what causes the red light anyway? The red can be caused by a variety of factors.

In this section of this guide, we’ll be looking at the most common reasons. Without further ado, let’s jump right into it.

1. Low Water Level

One of the most common and simplest reasons behind the red light on your Crane humidifier is a low water level. When your Crane humidifier starts running low on water, the red light comes on to let you know that it’s time to refill the water basin.

The Crane humidifier also has an auto shut-off mechanism that activates when the water levels drop to a critical point – which only happens when the red light has been ignored for a long time. This safety feature is designed to prevent overheating and damaging the nebulizer.

2. Stuck or Damaged Water Sensor 

Another common cause of the red light on your Crane humidifier is a stuck or damaged water sensor.

The water sensor in your device plays the role of detecting the amount of water in the tank. So, if it becomes damaged, gets stuck, or starts malfunctioning, the floater will not rise alongside the water level which will trigger the red light even when there’s enough water.

3. The Red Night Light Feature

Newer Crane humidifier models come equipped with a fun night light feature those cycles through different colors.

The night light feature illuminates the room while the humidifier is in use. It also helps you see all the controls and buttons clearly when adjusting the settings in a dimly lit room or at night.

The night light also adds a gentle ambiance to any room. This makes it easier for children and pets who may need extra light at bedtime.

For models with the night light feature, you’ll have to manually activate it via the app control panel or remote control. So, when activating it, if you select the red light or your device defaults to it, then you’ll notice the red light on your humidifier.

The good thing about this cause is that the red night light feature doesn’t require any fix and it’s nothing to worry about because the red light you are seeing is purely ambiance and nothing more.

4. Water Accumulation in the Humidifier’s Base

The Crane humidifier is designed to hold and vaporize water but it’s not waterproof. This means that if water enters where it’s not meant to, it can still negatively impact the device.

The bottom of the humidifier is where most of the electrical components in the device are housed. And unlike the water tank, the base is meant to be completely dry for the device to function properly.

So, if water enters the base, it can affect electrical components. When that happens, the red light will be triggered and in worse cases, it could lead to even more serious issues.

So be careful when cleaning or refilling your device to prevent water from getting into your unit.

When cleaning, try to clean areas where water can enter the device to prevent white dust and debris build-up.

How to Fix Crane Humidifier Red Light

Tired of seeing the red light on your Crane humidifier but don’t know how to fix it? Lucky for you, in this section of this guide, you’ll learn how to take care of the red light via simple step-by-step instructions.

Ready to fix the red light on your Crane humidifier? Try the following:

1. Refill the Water Tank with Distilled Water

As you already know, low water levels are a common reason behind the red light in Crane humidifiers.

To fix the red light in this case, all you have to do is refill the water tank. But before refilling the tank, make sure that your device is switched off and unplugged from its power source. It’s good to also rinse the tank and reservoir before refilling it – doing that prevents the device from becoming a breeding ground for mold and bacteria.

Once that’s out of the way, you can replenish the water tank with distilled water. To refill the tank, follow the steps outlined below:

  1. Gently remove the water tank from the base of the humidifier by lifting it straight up.
  2. Carefully turn the water tank cap counterclockwise and fill the tank with distilled water.
  3. Replace the cap and turn it clockwise until it clicks. After that, place the tank back on its base.
  4. Now, plug in the humidifier and press “On.” You can now adjust the settings as per the requirement for humidity levels.

It is important to note that different Crane humidifiers may require different steps to refill their tanks due to the manufacturing differences.

It is not recommended to use tap water in your humidifier as it may contain excess minerals that can accumulate in the tank. Apart, from the impurities commonly found in tap or hard water distilled water does not harbor mold or bacteria.

Using distilled water in your humidifier promotes the longevity of the device and creates a healthier environment.

2. Clean the Water Level Sensor

Over time dust or mineral content from the water can coat the water level sensor in your device leading to malfunctions.

Fortunately resolving this issue is simple. By cleaning your device, you can prevent dust and other particles from accumulating around the sensor and impacting its performance.

To clean the water level sensor effectively follow these steps.

  1. Begin by turning off your device and disconnecting it from its power source.
  2. Ensure that the water tank is completely emptied before proceeding.
  3. Remove the water tank from its base carefully. Take caution when detaching the float arm to avoid any damage.
  4. Thoroughly clean both sides of the float arm using a cloth or paper towel dipped in a solution of white vinegar or lemon juice. This will help dissolve any mineral buildup, on it.
  5. If you’d like you can also consider using a cotton swab dipped in either vinegar or lemon juice to clean the areas around the float arm.
  6. Once all components have been cleaned, reassemble them in their positions and refill the tank with distilled water before plugging it back, into its power outlet.
  7. During reassembly make sure that the floating ring is horizontal and securely place the cap on top of it. If you’re unsure if you’ve done it correctly perform a test.
  8. To confirm it functions correctly add some water and observe if the floater rises along, with the water level. This indicates that it has been fixed correctly or is undamaged.

Please note: Using cleaning agents other than a 50/50 vinegar solution or lemon juice may potentially harm the sensor.

If you continue to see the light after cleaning the water level sensor it could indicate that the sensor needs to be replaced.

3. Replace the Water Level Sensor

Sometimes just cleaning the water level sensor isn’t enough to solve the issue with the light. This might be because the water level sensor itself is damaged and needs to be replaced.

To replace the water level sensor, in your Crane humidifier here are the steps you should follow:

  1. First, make sure to turn off your device and unplug it from its power source. Then, empty out the water tank before proceeding.
  2. Next, remove the humidifier’s base to locate where the faulty sensor is situated.
  3. Once you find the faulty sensor, check your instruction manual for instructions on replacing it with a new, genuine Crane water sensor part.

If you don’t feel comfortable doing repairs, ask a handy friend or technician for help. It’s better to have someone experienced to handle the replacement so nothing gets damaged.

4. Dry Off the Unit

If you suspect that the red light on your device is a result of water inside the unit, then drying the unit will fix it.

Here are step-by-step instructions to help you with the drying process:

  1. Turn off your Crane humidifier and unplug it from its wall outlet.
  2. Remove any residual water from the unit by emptying the tank and wiping it clean using a towel or cloth.
  3. Place the unit in an open area away from direct sunlight for 24 hours or 48 hours to allow complete dispersion of any remaining moisture.
  4. Reassemble the device and plug it back into its power source.

Note: While drying out the unit prolongs its longevity, it is not recommended as a routine maintenance practice because it can lead to other issues such as the rusting of metal components.

Finally, if you experience any problems with reassembling your device, you should contact Customer Support immediately.
