How to Repair a Dehumidifier

Mar 30, †∑ If the dehumidifier has a drain line that runs to a floor drain, a full tank could indicate that the line has become kinked or is clogged. Manually remove the . Jan 26, †∑ To clean a dehumidifier filter, remove it and spray it with vinegar. Allow this to sit for 10 minutes, then rinse it thoroughly and spray it with hydrogen peroxide. Let this sit for 10 minutes, rinse again, and wipe it clean with a clean cloth or new sponge. . For proper operation, a dehumidifier needs to have an adequate amount of air blowing across the evaporator coils to prevent frost or ice buildup. If you feel little or no air coming through the grille area and the filter is clean, then remove the cover and check the fan area.

By Glenda Taylor. If the dehumidifier is plugged in and the outlet is working, the problem lies within the appliance itself. Most dehumidifiers come with a shut-off switch that turns the appliance off if the water in the collection tank reaches the top. If the dehumidifier has a drain line that runs to a floor drain, a full tank could indicate that the line has become kinked or is clogged.

Most dehumidifiers allow the user to select the desired level of humidity in the roomótypically 30 to 40 percent. When the humidity rises above that level, the dehumidifier turns on and removes moisture from the air. Check to see that the desired humidity level is set no higher than 40 percent, and turn it down if it is.

The humidistat is the actual component in the dehumidifier that turns the appliance on when moisture in the air reaches the preset level. Those familiar with testing electric currents can use a multimeter to test the humidistat for continuity ohms. Or you can ask a professional electrician or technician to test the humidistat. If the component has gone bad, ordering a new one from the manufacturer and replacing it is a relatively simple task.

The same principle that results in a glass of iced tea sweating in the summer is at work in dehumidifiers. Warm, moist air flows into the appliance where it comes into contact with ice-cold evaporator coils, causing the moisture in the air to condense and then drip down to a collection tank. However, if the room is cooler than 65 degrees, the moisture on the coils can turn to frost rather than condense and drain. When frost forms on the evaporator coils, it keeps the appliance from working efficiently.

Unplug the unit and lift the cover to check for frost. If you see it, leave the dehumidifier unplugged and allow the frost to melt, which can take a few hours, depending on how thick it is. Once the coils are clear, turn the unit back on and turn up the temperature in the room to keep frost from forming again. The coil system seals tightly to keep the fluid in, but tiny cracks can form over time, causing the fluid to leak out slowly.

Without sufficient refrigerant fluid, the evaporator coils will not become cold enough to draw moisture from the air. A plumber or HVAC technician can recharge the coils with more refrigerant fluid, but the cracks can be difficult to seal, and the liquid could leak out again.

The culprit could be a dirty fan or a broken fan blade. If comfortable checking inside the unit, unplug it and then remove the cover, then turn the fan blade by hand to see if either debris or a broken blade is keeping the fan from turning. Manufacturers carry replacement blades, which users can order and install, usually with the help of just a screwdriver.

If a broken fan motor is at fault, however, the fix is more complex. Replacing a fan motor is a job for a professional technician. If the fan is in good shape, something could be blocking airflow into the unit. This could be as simple as lint, dust, or pet fur buildup on the grill that covers the fan. A dehumidifier placed against a wall or next to an upholstered chair might not be able to draw in enough air. Position the dehumidifier at least a foot away from walls, furniture, curtains, clothing, and other items.

If a dirty or clogged grill is reducing airflow, unplug the unit, remove the grill cover, take it outdoors, and spray it clean with a hose. Dehumidifiers contain electrical components that can go bad, in addition to internal wiring that can short or come loose from connection terminals.

Models made within the past decade or so might contain electronic control boards that can burn out and stop working. Some of the tests require that the dehumidifier remain plugged in during the test, so the best option in this case is to take the dehumidifier to a small appliance repair shop or have a technician come out and take a look.

If the compressor is struggling to operate or if heavy frost develops on the coils, the compressor can become overheated. Most dehumidifiers have an overload switch that will shut an overheated compressor down to keep from damaging it. If this is the case, the overload switch will continue to flip even after resetting, and a technician will likely be required to pinpoint the cause.

Some users might opt to instead purchase a new unit at this point. Disclosure: BobVila. You agree that BobVila. All rights reserved. Expert advice from Bob Vila, the most trusted name in home improvement, home remodeling, home repair, and DIY. Major Systems Solved!
