The guide below is comprised in an order as if a technician would inspect the device. However, since some solutions are cost effective it is worth exploring them as they can save you the cost of brand new dehumidifier. Intent of this guide is to help homeowners troubleshoot and correct issues when dehumidifiers fail to collect water.
We also encourage if you find other solutions or issues while troubleshooting to please let us know via commenting below. Part Notes: It is best to purchase any parts directly from the manufacturer as it will meet the product requirements. Other types, however, especially those that use evaporator coils require relatively higher temperatures to function effectively.
These are often equipped with a fan that blows warm air over the coils. Nevertheless, when the dehumidifiers are placed in extremely cold places, the coils are likely to freeze up, which lowers their ability to remove excess moisture from the air.What to do When the Dehumidifier Ices Up or Freezes Up
In below video it is specific to Danby model however, most dehumidifier with capacitor issue can have similar troubleshooting process. This component is responsible for protecting the compressor motor from becoming damaged.
It accomplishes this by preventing excessive power flow within the device. Compressor is tasked with the responsibility of circulating the refrigerant throughout the system. A broken compressor can manifest through a clicking sound when the device is turned on. Besides a faulty compressor, a dehumidifier may also become ineffective when related components like the capacitor or the overload device fail both are discussed above as they are cheap repair solutions.
The refrigerant denotes the liquid contained in the evaporator coils, which helps to trap moisture from the air circulated within the dehumidifier.
How to Fix a Dehumidifier
When these tiny holes go undetected for long, the refrigerant might decrease to dangerous levels. This, in turn, reduces the ability of the dehumidifier to collect water. Leaks in the refrigerant coils can be corrected, but for this professional dehumidifier repair technician is required. However, it would be recommended to invest in a brand new unit due to the repair costs.
Faulty Fan System A fan is tasked with drawing in air from the environment into the system. This air goes through the condenser coils that help with condensing the humidity within it. Some of the factors that contribute to this issue include:. This component is susceptible to breakage, which mostly happens when it rubs against the housing. Solution: The best way to correct this issue is by replacing the fan blade which can be purchased directly from the manufacturer. If the fan blade wiggles, they should tighten the screws.
Why a Dehumidifier Won't Dehumidify
You should first determine whether the motor is getting enough power. If power is not the issue, the motor could be broken, at which point it requires replacement.
Solution: For defective fan motor it is recommended to get professional dehumidifier technician. This is still a cost effective solution. Other possible culprit preventing the dehumidifier from drawing enough air could be a blocked grill. As such, homeowners should inspect the grill for debris, dust or dirt and subsequently clean up such barriers. They should also remove any clothing that could be blocking the grill from outside.
This is the same grill that was shown in the Capacitor troubleshooting process above. If none of the above components have a defect, the problem could be within the electrical system. The electrical board, also known as PCB contains sensors that automatically detect the levels of relative humidity RH and kick starts the system when the desired moisture level is exceeded.
Solution: For defective PCB, dehumidifier should be checked by professional refrigeration technician. If you are unable to fix it and need to get a new dehumidifier then check out this guide for some very good dehumidifiers in the market. Updates: Jun 30Post was reviewed and edited by certified heating and cooling technician. I have gone through three basement dehumidifiers in five years.
In each case the compressor and fan run but no water is removed from the air.For the most part, dehumidifiers are trouble free, but they do require maintenance — emptying the tank, cleaning it periodically to keep bacteria and mildew in check, vacuuming the dirt from the coils, and replacing the power cord and plug if they get worn.
In the summer, excessive humidity saps our energy, robs us of sleep, causes health and safety problems — especially in the elderly — and makes basements smell damp and musty. Equipped with an evaporator coil, compressor, fan, and humidistat, dehumidifiers wring moisture from the air. A comfortable moisture level during the summer is 35 to 40 percent. If it gets cool outdoors and you keep the dehumidifier in the basement, the coils will freeze up if the dehumidifier is switched on.
Fortunately, all you have to do is turn it off manually and when you need it again, turn it back on.Seo skills
When humidity is high, a portable dehumidifier with a 4-gallon tank needs to be emptied at least once a day. Dirty coils also cause freezes. So whenever they accumulate a lot of dust, clean them. If you notice one or more fan blades are bent, they will have to be replaced before they damage the motor. Then head to the nearest appliance parts store. Take the humidistat to an appliance parts store along with the numbers off the data plate to find the right replacement.
Install the new humidistat by following the first four steps in reverse order. Gary and Peg Hedstrom are self-taught repair masters with experience in carpentry, plumbing, appliance repair, and more. Judy Ondrla Tremore is a writer and editor for various newspapers and magazines. How to Maintain and Fix Your Dehumidifier. About the Book Author Gary and Peg Hedstrom are self-taught repair masters with experience in carpentry, plumbing, appliance repair, and more.But as mechanical devices, dehumidifiers contain complex inner workings with various components and parts.
First check if the main power panel switch, to the dehumidifier, is in the ON position. Confirm that the controls are on the ON position. Verify that the humidistat is set between 50 and 60 percent relative humidity. If the dehumidifier still does not operate call a competent HVAC servicer. Assuming that the dehumidification system was effectively operating in the past look for these simple repairs.
If the blower in the dehumidifier is running it is possible that the compressor is not operating. Check to see that the indicator light, on the dehumidifier, is confirming that the compressor is operating.
If the compressor is not running call a competent HVAC company for service. Using a separate calibrated hygrometer to determine the actual relative humidity in the pool room. If it shows that the actual humidity is between 50 and 60 percent it is possible that the humidity sensor or the humidity control is defective. Verify that the pool water temperature is 2 degrees below the actual room temperature. If the room temperature feels cool or is over 5 degrees below the water temperature it is possible that the room heating source is not operating.
Assuming that the dehumidification system followed the proper start up procedure and met expectations previously the following may now be the cause.
The blower belt, in the dehumidifier may be worn or stretched or both. Replace belt and tighten to the proper tension.
Check to see that the diffusers, on the registers for the dehumidified air, have not been obstructed or the dampers closed off inadvertently. The return air filters in the dehumidifier are clogged and restricting air flow back to the dehumidifier.
Replace return air filters per the instruction manual. If the dehumidifier is tripping the high head pressure switch during the cooling mode it is possible that the remote condenser coils are plugged with lint, grass or leaves restricting air flow or the blower belt if applicable needs attention. Maintenance is critical for the successful operating of the dehumidifier and that also insures a long trouble free service life.

A dehumidifier is a box that contains cold evaporator coils, warm condenser coils, a fan, and a reservoir or drain to catch water.
The fan blows moisture-laden room air over the cold coils, where water condenses and drips into the pan or drain. Although a dehumidifier does not cool the air, it makes it more comfortable because it decreases the humidity. But a dehumidifier does not function well under about 65 degrees F. Be sure it is plugged into a working outlet and is turned on. If necessary, replace the appliance power cord. If you see any ice blocking parts, let the ice melt and do not use the unit until the room temperature exceeds 65 degrees Fahrenheit most dehumidifiers are not designed for use in colder spaces and may freeze up.
Many people find that by unplugging the unit and waiting about 30 days into the season the problem is solved.My playhome hospital apk
Inexpensive volt-ohm multimeter will handle most electrical testing. Buy on Amazon. You can do this with a volt-ohm meter. Clip the leads to the terminals on the switch. Depress the bar or trip lever on the switch. Use a volt-ohm meter to check the overflow sensor. You can test a dehumidifier humidistat fairly easily using a volt-ohm meter.
Also using a volt-ohm meter, you can tell if the overflow switch works or not. If your dehumidifier seems incompetent, it may be undersized for the space. After disconnecting the power cord, you can also:.B450 pro4 not booting
Many dehumidifiers have a float switch that prevents the unit from spilling over with the water that has been drawn out of the air. Sometimes this switch goes bad and must be replaced. If your dehumidifier is overflowing, you can test the overflow prevention switch with a volt-ohm meter. Is your dehumidifier freezing up? A dehumidifier will often frost up if room temperatures are colder than about 65 degrees Fahrenheit. Dehumidifier has a pint water collection tank.
If the room temperature is lower than 40 degrees F. A clear indicator of this is an evaporator coil that is frosted up completely and evenly see Step 5 for information on opening the unit. If you suspect that your room temperature may be too cold, try setting the dehumidifier on a table so that it circulates slightly warmer air.
You can also try aiming a small blower or heater at the unit—if this solves the problem, consider raising the room temperature slightly. Anything that prevents room air from freely moving through the unit can cause the dehumidifier to freeze up. However, do not place it in a drafty spot. In most cases, you use a vacuum cleaner to do this; foam filters can be cleaned with spray from a faucet. If the coils inside the unit are dirty, they cannot operate efficiently.
Unplug the dehumidifier and open it up by removing the screws that secure the outer cover. Note whether the coils are completely iced up or only partially iced up. If only certain sections of the coils are iced up, the problem is likely to be caused by low refrigerant or a failing compressor see Step 8. Allow all ice to melt and excess moisture to evaporate from the coils.
Then, using a brush attachment on a vacuum cleaner, remove all dust buildup, being careful not to damage the coils. Drain the unit and allow it to dry completely before putting it back together and plugging it in.Dehumidifiers work in the much the same way as air conditioners. Both contain refrigeration coils that cause moisture to condense out of humid air.
In fact, American engineer Willis Carrier was actually searching for a way to control humidity when he invented modern air conditioning. The main difference between a dehumidifier and an air conditioner is that a dehumidifier reheats the air that passes over its refrigeration coils before blowing it back in the room. When a dehumidifier won't do its job and stops removing moisture from the air, the filters are the first thing to check, because they could be impeding air flow. It's also possible the coils need cleaning or de-icing.
These are repairs you can do yourself, but fixing problems with the refrigeration system, such as leaks and compressor malfunction, is a job for a licensed refrigeration technician. If you can understand an air conditioner or a refrigerator, you can understand a dehumidifier. The cooling is provided by the change of state of an inert chemical—called a refrigerant. The condenser compresses this refrigerant in its liquid state and forces it through a tiny aperture into a system of coils.
As the refrigerant passes through the aperture, it vaporizes, which is an endothermic reaction that draws heat from the surroundings. The sudden cooling condenses moisture out of the air surrounding the coils. The condensation collects on the coils and drips into a drainage system, reducing the humidity of the air that exits the appliance. The efficacy of this process depends on the air flow around the coils. If air can't get into the chamber in which the coils are located, or it can't get out, the humidity around the appliance won't change.
Many dehumidifiers have two filters—one on the inflow side and one on the outflow side. Remove both filters and clean them periodically with soap and water—or replace them—to keep the appliance working in top form. You may need to consult the manual to determine how to access the filters. If you don't have a manual, you can find one on the manufacturer's website or by doing an online search of the make and model of the dehumidifier followed by the word "manual.
Almost every dehumidifier comes with a built-in reservoir that you can use instead of hooking the unit up to a drainage hose. When the reservoir fills up, a switch shuts off the condenser to avoid an overflow, and a warning light illuminates on the control panel. Empty the reservoir, replace it, and the unit will start running again.
When the temperature in the room is below 65 degrees Fahrenheitfrost may form on the evaporative coils, and it can eventually turn to ice.Synology connection timeout

Had this dehumidifier for less than 2 yrs and the compressor will not kick in. It is a Soleus Air, 70 Pint, Portable. It blows cool air is all. Any ideas or is it garbage? View Public Profile.Do not disassemble the dehumidifier if you are unsure you can. Instead, contact the dehumidifier manufacturer for service. Dehumidifiers are designed to pull hot, humid air into the unit and separate the water from the air, collecting the water in a tank and sending the now drier air back into the living space.
While not all dehumidifiers have a sensor, some have a humidity sensor that helps adapt the dehumidifier to maintain the set relative humidity point.
If the sensor gets dirty or cloudy, sensor effectiveness will be reduced. Troubleshooting the sensor can often help avoid this problem. Disconnect the sensor assembly from the main control panel and remove the screw holding the humidity sensor in place. Replace the humidity sensor and screw into place, then return the main panel and fasten the panel into place.
Restart the dehumidifier and monitor its performance. If the sensor does not seem to be working better, contact the dehumidifier manufacturer for assistance.
