SOURCE: kenmore dehumidifier runs but won't collect water

Hi,
If you haven't done so already, try removing and cleaning the inlet filter screen which is almost certainly just behing the inlet grille. It may slide upwards out of the casing or downwards unto the bucket area. If this is blocked with fluff then no moist air will get to the cold pipes, so little or no water will be extracted. There's also a chance that the humidity sensor is clogged with fluff, so fooling the system into thinking the room is pretty dry, in which case the compressor will probably not run.
A running compressor can usually be detected as a deep throbbing from the machine. If it is running, but not cooling the pipes behind the intake grille, then you may have lost the refrigerant from the system via a leak. If the air coming out of the machine is warm (caused by the compressor running) but there is no water produced this may be the cause.

Explore along these lines and let me know what you find.
Cheers, D

SOURCE: Kenmore 54701 (70 pt) dehumidifier is not prerforming properly

could be a bad humidistat or a bad PTC relay on the compressor, check for voltage going to compressor, and check neutral continuity, if there is both then you have a bad compressor, check warranty on comp replacement, if no voltage then the humidistat is probably bad

The black cylinder is the compressor. It sounds like your unit is cycling the compressor for some reason. If the compressor starts, runs fine, and removes water when you set the humidity control to the driest setting the compressor is probably OK and the problem may be with the humidity control causing the dehumidifier to "short cycle" for some reason. You may need to change the humidity control or relocate the dehumidifier in your crawl space.
If the compressor attempts to start, and then sits quiet for 10 minutes, and then attempts to start again, you have a problem with the dehumidifier. There are a few things that can cause this problem:
Low refrigerant charge
Bad compressor capacitor
Bad compressor overload
Plugged capillary tube or broken expansion valve
are the common causes of this behavior. If you suspect one of these problems, call the factory service department at 1-800-533-7533 for help.

Good luck with your dehumidiifer.

Are you keeping all of the metal covers in place while the machine is running? If you remove some of the metal covers, the fan may not move the air through the dehumidifier as intended.

If the compressor runs (with all of the metal covers in place) and the accumulator does not become cold, there are a few things that may be affecting your dehumidifier.

1. low refrigerant charge - you may have a refrigerant leak.
2. blocked capillary tube or broken expansion valve.
3. blocked air filter prevents enough air from moving through the dehumidifier.

Fan runs but does not collect water


It sounds as though the compressor is not running or the machine is low or out of refrigerant.

Unit runs but no water collects in bucket. Unit is over a year old and has run continuously that whole time. Up till now it has performed beautifully. Is it just worn out?


Hi;
Your dehumidifier is similar to a refridgerator or air conditioner. It has a compressor and coils, and a fan. Basically, the unit has to **** in air with it's fan, and as the humid air goes across the cold coils, the humidity condenses in to water. If the coils are not getting cold, they won't condense any water, or if the fan isn't running, or the coils are dirty. If you check your unit over, see if you can tell if anything isn't working. Make sure the control knob is set at the highest setting. If the compressor lost it;s refridgerant charge, and won't get cold, it isn't probably worth fixing

The humidifier runs but is not collecting water... so humidity level never drops.


My brand new frigidaire 50 liter dehumidifier has been on for two days and has not collected water from my damp basement. It is on the factory settings: high fan and "CO" (continuous).

Running but not collecting water...


Dehumidifiers have only a few components, and operate on the same principle as a refrigerator, freezer, or air-conditioner.
Components Residential dehumidifiers have a cooling system made up of these primary components:

  • The compressor is the quiet motor (engine) of the cooling system. It's the black, football-size component at the bottom of your dehumidifier. The compressor runs as long as the dehumidifier humidistat (the humidity-sensor) calls for a reduction in the humidity.

  • The condenser is a series of finned tubes, similar to a radiator. It's usually near the circulating fan.

  • The evaporator is located near the back of the dehumidifier, right above the water-collection container. It also resembles a radiator or a coiled-up set of tubes. When the dehumidifier's humidistat senses increased humidity, it cycles on, which starts the compressor and circulating fan.

  • The circulating fan circulates the air over the evaporator and condenser coils.

Principle When the unit runs, the circulating fan and compressor also run. The fan continually draws room air over the evaporator coils, which are cold, and then over the condenser coils, which are warm. Because the evaporator coils are cold, the moisture in the room collects on them--just as the outside of a glass of icy liquid "sweats" on a warm, humid day. When the moisture on the coils increases, it drips off of the coils into the collection container.

The air then flows over the warm condenser coils and out into the room. This process removes water from the air and, because of the heat from the fan motor and compressor motor, the exiting air is somewhat warmer, as well as dryer.

Humidifier Runs but no water collected


Are you talking about a dehumidifier or a humidifier. If you are talking about a dehumidifier, it works by blowing air across a cooling coil causing condensation and the water will drip and pool. The cooling is caused by a compressor working like refrigerator, but using the effect to dehumidify. To check if the cooling coil is working there will be a metal can like in it with tubes in and out. One of the tubes should be warm(input) and the other tube should be cold, if not your compressor is not working. If freezing up, low freon. Check to see if the compressor shuts off very quickly, that would be too much freon. This is not user servicable. Now a humidifier works several different ways. One way is a fan with cloth belts rolling through water using evaporation to humidify. Another way is for a circular fan like on a motor to turn. It has a hollow piece into the water. It picks up water and then through centrifugal force aerates. One way is for a sonic humidifier. All the types have a problem with eventual calcification or mineral build up in the water handling paths. Lime-away or Concentrated Lemon Juice will dissolve this. The lemon juice is the most fun. It will turn your toilet bowl white and also remove rust stains from laundry...
