After being told by a service repairman that it would cost me close to $200 to repair, I resolved to just not use the dispenser.
If the volt-ohm meter registers zero ohms through only part of the humidistat dial’s range, the humidistat is working. If it registers zero through the entire range, it’s broken and must be replaced. 6 If the unit still doesn’t work, decide whether you’re better off replacing the appliance or calling a repair person (this decision will depend upon the value of your dehumidifier)—the dehumidifier compressor motor or the relay and overload switch may be the problem. It’s usually best to replace the. 3-in-One All-Purpose Household Oil (under $5 on ) 2 Lubricate the fan motor bearings with a couple of drops of lightweight household oil (such as ) if the motor has oil ports (some dehumidifiers don’t need to be oiled). While you’re at it, make sure that the condenser isn’t clogged with dust or dirt.
3 Finally, make sure your humidistat is functioning properly by testing it with a. Just set the meter to RX1 scale and attach its leads to the humidistat’s terminals. Rotate the humidistat’s knob as far as it will turn in both directions. If the volt-ohm meter registers 0 ohms through only part of the humidistat dial’s range, the humidistat is working. If it registers 0 through the entire range, it’s broken and must be replaced.
4 If it still operates poorly, call an appliance repair person for advice or take the unit into an appliance repair shop, or buy a new dehumidifier. Dehumidifier Overflows or Leaks 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. 1 Unplug the dehumidifier and remove the switch.
2 Disconnect the leads and clip the leads of the volt-ohm meter to the terminals on the switch. 3 Check the pan or reservoir and empty it if necessary, or make sure the drain isn’t clogged. 4 Straighten any kinks or bends in the unit’s hose. 5 Set a volt-ohm meter to the RX1 scale (or to K-? Resistance on a digital meter) and depress the bar or trip lever on the switch. If the meter’s needle shows no continuity as the switch is clicked back and forth, the switch is probably faulty and will need replacement. Dehumidifier Freezes Up Is your dehumidifier freezing up?
If your dehumidifier ices up, it’s important to solve the problem—running a dehumidifier that’s totally iced up can damage the compressor. A dehumidifier will often frost up if room temperatures are colder than about 65 degrees Fahrenheit. Though some “basement humidifiers” are designed to work in temperatures below 65 degrees F, conventional humidifiers are not. Frigidaire Dehumidifier has a 50-pint water collection tank. If your room temperature isn’t overly cold, airflow to the unit may be restricted or blocked, the unit may have a faulty de-icer switch, the refrigerant gas in the unit may be too low, or the compressor may be failing. To troubleshoot a dehumidifier that freezes up: 1 Take a look at your room temperature, as previously stated. If the room temperature is lower than 40 degrees F., the dehumidifier will definitely freeze up.
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. 2 Be sure the unit is set far enough from the wall so that airflow isn’t restricted.
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.) 3 Be sure the fan is working. If you don’t hear the fan blowing air across the coils when the unit is turned on and supposed to be operating, the dehumidifier will freeze up. 4 Clean the filter if it has one. If your dehumidifier has a filter, follow the manufacturer’s instructions to clean it.
In most cases, you use a vacuum cleaner to do this; foam filters can be cleaned with spray from a faucet. 5 Vacuum the condenser coils. 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. 6 If vacuuming the coils doesn’t do a good enough job of getting them clean, take the unit outside, cover the motor and electrical parts with plastic sheeting, and spray the coils with water. Drain the unit and allow it to dry completely before putting it back together and plugging it in. 7 Test the unit.
After plugging the dehumidifier in, turn it on to see if it freezes up again. 8 Make a decision. If it still doesn’t work, it is probably low in refrigerant. Now you have to make a decision to either take it into an appliance repair shop or toss it and buy a new one.
Before taking your dehumidifier into a repair shop, get a phone estimate of the cost of recharging and/or repairing it. Then evaluate whether or not it’s worth doing. If you decide to buy a new one, please see the free.
Dehumidifier Smells Bad Does your dehumidifier smell bad? If your dehumidifier stinks or smells musty or like sulfur or mold, this expert advice will help you troubleshoot and solve the problem. Dehumidifier odors are generally caused by stagnant water that has pooled in a hose or by chronically dirty condenser coils. Though you might be tempted to clean it with some type of disinfectant or household cleaner, resist the temptation! You should not use any type of chemicals in a dehumidifier—the residue is too difficult to remove and some chemicals can be caustic. Instead, use vinegar (its smell with be strong at first but will dissipate with time), hydrogen peroxide to clean the reservoir, coils, and filter. Use these two non-toxic chemicals in sequence, applying and removing the vinegar first, and then the hydrogen peroxide, which helps remove the vinegar’s odor.
How to Clean a Dehumidifier After unplugging the dehumidifier, take it outside to work on it. Here’s how to clean it to rid it of odors: 1 Fill one spray bottle with full-strength white vinegar and another spray bottle with full-strength hydrogen peroxide. 2 Clean the reservoir / drip pan.
Start by completely emptying it and mopping up any damp areas. Then spray the inside of the reservoir /drip pan with vinegar, allow to sit for 10 minutes, and then rinse thoroughly with clear water. Use a clean rag or new sponge to wipe it out and repeat the rinse and wipe process. Follow up with the hydrogen peroxide, following the same methods. 3 Clean the coils with an inexpensive (available online or at hardware stores) and a garden hose. Be very careful not to damage the coils. Then spray them with vinegar and allow to sit for 10 minutes.
Rinse thoroughly with water, wipe clean, and repeat with hydrogen peroxide. Allow the unit to dry in a warm place for at least 24 hours. 4 Clean the filter.
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. 5 Wipe the fan blades clean. Remove the cover first, then use a damp cloth to clean the fan blades and the area around the motor.
Put two teaspoons of baking soda in the dehumidifier’s tank to prevent future mildew and mold odors. In the future, empty the dehumidifier regularly so that it doesn’t have time to grow mold or bacteria. Dehumidifier Is Noisy Is your dehumidifier making strange noises?
If it is, the noises are probably caused by loose, vibrating parts. After disconnecting the power.
How to clean, examine, troubleshoot and track a problem with a dehumidifier. This will likely help you with any dehumidifier or air conditioner or refrigerator that is not working. Please understand that this is a documentation of a repair attempt that I made and it is for informational use. Anyone attempting to do such a repair should not proceed unless they have taken a course in electronics and understand electricity and how it can hurt you. If you have not been properly trained and are not confident then don't do it.
The following is the script for this with a few extra comments. I'm showing a series of images of the disassembly and cleaning of this unit while I narrate.
Generally I'm pretty much a fixit and reuse it enthusiast and I benefit very much from what I learn online from others who have fixed the same or similar items. So I did a photo play by play of this fix attempt. I think it will help you in knowing what to expect and what can go wrong with a dehumidifier appliance. This one is a Whirlpool Accudry Dehumidifier. Model # AD25G0 Of course the first step to a repair like this is to do a quick web search using the name and model number of your appliance to look for the manual and parts list assuming you don't have them. If you're really lucking it my lead you to a 'how to.
Video' After checking the trouble shooting suggestions in the manual it's time for what you've been watching for the last 45 seconds. Fortunately all the screws on the chassis were the same size and with a power screwdriver you can have them all off in no time. You have to watch and carefully analyze plastic tabs on the cases so you don't break anything. Patience is your friend and if you're losing it you need to step away for a while. You have to realize that though something seems to be stuck like a puzzle there's tab to push somewhere and you just have to solve it by thinking.
The problem with this particular unit is that while fan runs, the compressor doesn't pump the coolant so it doesn't get cold and condense water. Using a voltage meter you can determine where the electricity is going and where it's disrupted. You have to remember to put the collection bucket in place while testing because there's a trip switch that cuts the power when the bucket's not in place. The power I discovered gets all the way to the compressor and to take it a step further I have to remove this metal retainer that's holding an insulated cover. Remove this only with the power off.
Clearly it's insulated for a reason. Removal of the cover reveals two more components before the compressor. According to the parts list the round cylinder is called the Overload Protector. I found that the current goes in one side but does not come out the other side. It looks like this is permanently mounted but with the power off again I find it to be another retaining device called the overload spring and by pushing it down it pops free. Upon flipping over the Overload Protector we can see what has happened.
The Overload Protector (which is like a fuse) has burned out. This is a pretty bad sign because for something like this to happen there was a pretty heavy load on the circuit and most likely the compressor has seized rendering the unit not worth fixing. This is pretty much the heart of the unit with metal pressure tubes attached. It's pretty safe to assume it's time to recycle this unit.

However since you've been patient enough to watch up to this point. I'll do one more thing that you should never do.
I'm going to bypass the Overload protector which will lead to some fireworks so I'm going to use a thin piece of soldier that will melt like a fuse if the compressor is seized. I'm also using a power-strip with it's own fuse as another safety precaution.
Don't try this at home. For the most part the demo is over but for those in the manufacturing industry lets reexamine our goals as human beings in a shared biosphere. Planned obsolescence is a painfully shortsighted business plan, but when you manufacture something that contains freon as well, it's damaging to our shared environment. This Whirlpool unit should have lasted a lifetime but a seized compressor has rendered it useless.
The unit contains a gas element that when released causes serious environmental damage in this case depletion of the ozone. This event causes me to reevaluate Whirlpool which I had previously considered a world class corporation. How can I or any viewer of this video ever consider buying a Whirlpool appliance again?
I would invite any member of the board of directors at Whirlpool to respond to this question. I don't want to hear 'Everyone else is manufacturing at a sweatshop in China and we have to stay competitive.' You're Whirlpool!'
