    not very good. R22 becomes outlawed 2012, due to CFC's and should only be a virgin top up until the end of 2009, and if its leaked you have a leak to fix first before you can top it up. you need a refridgeration engineer to do this some refridgerant gasses are highly flammable

SOURCE: Goldstar DH304 Freezing up / no water in bucket

Thermostat or the temperature control module are not working properly. Also make sure that your fan blades are not broken or warped as this will cause you a problem. Also if the coils have or do get iced up then it will be a low coolant problem. But this is a thermostat or temp control problem

SOURCE: runs great but no water in bucket ,whats wrong

either there's no moisture in the house (especially if you have an air conditioner), the coils are not cold enough, or there's no air flow across the coils. if the latter is the case, clean off the rear coils, clean off the front filter (or if no filter, the fins), and see if the fan is working. cleaning the condenser coil fins in the front would also help with it not getting cold, if that were the problem.

My fan runs but the compressor does not start on my whirlpool model ad25bsro so no water is collected.


1st ck that the bucket full light is not on , reguardless if bucket is m/t and in place , if light is on then the float sensor inside bucket container needs looked at , if no light is seen then it's common on new units to run the circulation fan all the time , and cycle the compressor on the humidistat's setting , reverify what the settings are for your room , std setting is 70%rH for a home , also a seperate meter to indicate %rh might help to determine if your unit is working properly (there not expensive) it migtht be that your room is dry enough and unit is not calling for water removal

Dehumidifier Problems and Dehumidifier Troubleshooting


If you have a dehumidifier that is not working correctly you have many things that could be causing it not to work. Here I will give some of the common reasons why it could be giving you problems.

0ebf56c.jpg
  1. The coils in the back are frosting up.

The dehumidifier works by drawing the room air over a very cold coil. The trick is to keep the coil as cold as possible to make it pull water out of the air by making it condensate on the cold coil. If this coil becomes too cold, then the water freezes on the coil. The freezing can happen if the air temperature in the room is too cool and does not keep the coil warm enough. Raising the humidifier up off of the floor onto a table can help. The air temperature is often a bit warm the higher up you get. Make sure that the filters are clean if your unit has one. Restricted air flow will make the problem worse. Providing more heat to the room will help also. Most units will not work in a room with temperatures below 68 degrees F.

  1. There is no air moving over the coils.

This can happen if the fan motor becomes stuck or burns out. If it becomes stuck you can sometimes get it running by working a lubricant into the bearings. WD-40 first, and then a good motor oil. If the motor burns out it will need to be replaced.

  1. The indicator light is on and the unit will not run.

This shows you that the bucket is full and needs to be dumped. If your unit is working correctly and the air is very damp you may only run a few hours before the bucket becomes full. This also can happen if the bucket is not seated in it’s spot correctly. There is a little switch that will not let the unit run if the bucket is not place exactly right.

  1. There is no water being produced.

This can happen if the air is very dry and no water can condensate from the air. Check the coils to see if they are cold to the touch, actually they should be very cold, like almost freezing. If not then the refrigeration system of the dehumidifier has gone bad. To repair that you will need a person certified to work on refrigerant systems with specialized equipment. In many cases the costs to repair the refrigeration systems will more than the cost to replace the whole unit.


This should give you a brief overview of the problems that you can have with a dehumidifier and some of the things that you can do to help get things working.

Does not collect water in bucket but runs all the time


Does it have a filter?
http://whirlpool.custhelp.com/app/answers/detail/a_id/953

also:

"
It may be that the humidity level or temperature in the room where your dehumidifier is located is too low.

When the outdoor temperature is below 50 F, the indoor air will be dry even when the air inside is warm, therefore when it's cold outside the dehumidifier may collect little or no water.

Air conditioners will also remove moisture from the room, even if it's hot and humid outside, resulting in little or no moisture collecting in the dehumidifier bucket.

Some dehumidifiers have a deicer which turns off the compressor but keeps the fan running. When the compressor is off, moisture is not removed from the air. The deicer turns off the compressor when the room temperature is cold.

Some dehumidifiers do not have a deicer. If the room temperature is low enough, ice may form on the evaporator coil. The ice prevents the dehumidifier from removing and collecting water. If ice forms on coils, unplug dehumidifier until ice melts and room temperature rises."

Our dehumidifier is not taking moisture out of the air and putting water in the bucket but everythings to be running fine


If the machine's compressor runs when you switch it on, then turn the machine on maximum and let it run for an hour or so. Then check the coils in the back with your hand. If they are not getting cold at all, then there is a significant problem with the refrigeration process in the unit. It may have developed a leak and allowed your refrigerant gas to escape, or there may be another internal problem with the compressor. Either way you would need to have it serviced by a fridge technician, or more likely just replaced with a whole new unit since both options can potentially cost about the same.

If the unit runs normally and the coils are getting cold, then make sure they are not totally icing up which will impede the unit's performance. Also make sure that the room is warm enough. A dehumidifier will not work properly if the ambient air temperature is too low. Basically, the warmer and more humid the room is, the better they work. Add heat to the room if necessary to improve the unit's performance.

The filter (on some models) may be dirty or clogged. If so, clean the filter. For instructions on cleaning the filter.

Why would it not take water out of the air, it runs so long it creates ice on the outside of it. With no water in the bucket. its in the Basement its 52 degrees and the humidie is 84. what can i do to...


Room must be above 60.

If the room temperature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

No water in bucket after running 8 hours. Very clean, no lint or dust anywhere! All settings on the top are correct. Used to work fine and then just one day it stopped completely. Thank you for your time...
