How To Fix It

Why Crane Humidifier Is Not Working?

Crane humidifiers, like other humidifiers, can develop problems from time to time. The good news is that these appliances have a simple setup which means that you can easily fix most of these issues. 

Your Crane humidifier may not be working if there isn’t enough water in the water tank and basin. If your appliance isn’t coming on, it means there’s a problem with the power source or the unit itself. If you’re unsure of the problem, it’s best to contact Crane customer support. 

If you’re having problems with your Crane humidifier, this guide will show you some things you can do to address and solve them. 

Crane Humidifier Not Working Red Light

One of the reasons the red light on a Crane humidifier turns on is that there isn’t enough water in the water basin. This feature has been preset into the system to prevent overheating and potential damage to the heating element or nebulizer. 

Refilling the water tank can help fix this problem and get your device working correctly again.

However, Crane Humidifiers suggest emptying the water first before refilling it. Also, for safety reasons, you should turn off the unit and unplug it from the socket before starting the refilling process. 

Once the system detects enough water in the tank, the power indicator will change to green, and the mist lid will start emitting mist. 

Your Crane humidifier may also turn on the red light if you don’t secure the water tank cap to the water tank correctly. In this case, you have to put the lid on it properly and ensure it is unobstructed. 

Another reason your power indicator may turn red is when the water level sensor is dirty or damaged. If it is dirty, you can remove it and wipe its parts with a soft, damp cloth. However, if the water level sensor float is damaged, you’ll have to replace it. 

Sometimes, water accumulation on the circuitry can cause the indicator light to flash red. In this case, you’ll have to dry out the entire unit and stop using it for a while. Usually, around five days of not using the humidifier will do the trick. 

Still, if you’re unsure what the problem is, it’s best to call a professional.

Crane Humidifier Not Turning On

If your Crane humidifier is not turning on at all, it means that something is wrong with the power and setup. 

In this case, the first thing to do is to ensure that it is plugged into a working socket. Also, ensure that the control knob on the side of the device is turned ON before jumping to conclusions. 

If everything seems fine and it still doesn’t come on, the power coming in may not be adequate. 

Crane humidifiers generally come with a short power supply cord to reduce the risks of longer cables. So, if you’re using an extension cord, it may be the source of the problem. 

First, ensure your extension cord has a rating of 125 V, 13 Amps, 1625 W. Also, ensure that other appliances in your home do not overload it. Instead, plug your unit into an outlet all on its own. 

You may also want to use a power strip since it can protect your humidifier and the unit from overloads or surges.

Your circuit breaker may also cause your Crane humidifier not to work. If you use an old wiring system in your home, the circuit may trip if you connect a high-powered device to it. 

If the power outlet is not the source of the problem, then it may be your humidifier itself. In this case, you’ll have to take it to an expert or contact Crane customer care.

Crane Humidifier Fan Not Working

A fan malfunction is one of the most common problems with Crane humidifiers. The fan outlet is located beside the Nebulizer at the humidifier’s basin. 

If your humidifier fan is not working, the fan vent may be obstructed. So, check the humidifier basin and remove any blockages. 

Also, water may get into the device’s basin and cause the fan to malfunction. If you’re handy, you can loosen the parts and clean them with a damp cloth or vacuum. However, when cleaning the fan vent, keep water away from it. 

You can also wiggle or spin the fan to see if it turns freely and is not loose on its shaft. If you can figure out the problem, it’s best to call an expert as the fan may need a replacement. 

Remember, before attempting any cleaning or repairs, unplug the unit from the outlet, empty water from the reservoir, and wipe up the damp areas.

Crane Humidifier Blinking Blue Light

If your Crane humidifier is blinking with a blue light, the water tank may be the source of the problem. 

First, check to ensure there is enough water in the tank. This problem may also occur if you have put too much water inside. 

To fix this problem, empty the water basin and fill the tank correctly. After filling it, press the reset button located at the humidifier. 

Also, ensure that nothing is obstructing the lid on the top of the appliance. 

Mineral deposits may also build up on the water level sensor and heating element and cause the indicator light to keep blinking blue. 

Mineral scale may be your problem if you use tap water, as it contains minerals and impurities. When water moves over the heating element, evaporation occurs, leaving a layer or coating of minerals that build up over time. 

As this layer becomes thicker, it prevents mist from forming. 

Fixing this problem involves chipping off the mineral deposits on the heating element and thoroughly cleaning it. Avoid cleaning with sharp objects as they can damage the parts and worsen the problem. 

If this issue keeps occurring, I recommend changing from tap water to filtered or distilled water.

Crane Humidifier Keeps Turning Off

Your Crane humidifier can keep turning off if you don’t place it on a smooth and level surface. The surface should also be non-metallic, lint-free, and not in the path of direct sunlight. 

This problem may also result from the obstruction of the fan vent, so avoid placing it on the carpet or a towel. 

Also, overheating can cause your Crane humidifier to keep turning off. First, check that there is enough water in the tank. Depending on the temperature in your area, the tank may require refilling several times. 

This problem may also occur if you set the incorrect humidity output. If the mist intensity is too high, it won’t be able to move away from the humidifier fast enough and instead accumulate on the humidifier’s surface.

You can fix this issue by adjusting the mist output intensity to low to medium. 

You may also try leaving the room door half when the humidifier is working and see if it solves the problem. 

How To Maintain Your Crane Humidifier?

One of the best ways to keep your humidifier free of any problems is to practice regular maintenance and cleaning. To extend the lifespan of your appliance, you should practice daily, weekly, and end-of-season maintenance based on the manufacturer’s instructions

Daily Maintenance

To prevent bacterial growth in the water tank: 

  1. Turn off the humidifier. 
  2. Unplug it from the power source.
  3. Empty water from the tank daily. 
  4. Also, wipe the humidifier’s basin with a soft, clean cloth or paper towel. 
  5. Ensure the tank and basin are dry before using the appliance again. 

Weekly Maintenance

Here’s how to perform weekly maintenance of your Crane humidifier: 

  1. Unplug the appliance from the power source and empty the water from the tank and basin. 
  2. Fill up to half of the tank with warm water. 
  3. Pour 2 or 3 tsp (10-15 ml)  white vinegar into the basin and shake it vigorously. 
  4. Leave it for at least 20 minutes before emptying the tank’s contents and rinsing with clean water. 
  5. Add warm water to the basin and pour up to 1 tsp (5 ml) white vinegar.
  6. Again, shake it vigorously and allow it to sit for about 20 to 30 minutes. 
  7. Empty the solution and rinse the basin with clean water. 
  8. Wipe it with a soft dry cloth and allow it to air dry. 

End-of-Season Maintenance

The end-of-season maintenance is similar to the weekly maintenance. Never leave water in the water for more than a day or two, as it can become a breeding ground for bacteria. 

After emptying and cleaning the tank and basin with white vinegar, allow all the parts to air dry and remove the cap from the tank until you need it again. 

Finally, store the unit in a cool, dry place.
