    Setting is below ambient humidity level (so runs constantly).

    The compressor is overheating and there is no water filling the bucket. It was so hot that I could smell the plastic overheating ...

    It's just over a year old. Why cant they make these better products so I dont have to buy a new one every 2 years... of course "Made In China"

    Same problem with a 2-yr old. unit.. runs but does not extract water but humidity level shows 75% so bought a new LG one which shows same humidity level and works fine (extracts a lot of water)..So is the maytag worth repairing? If so, where?

    It's running, but it doesn't collect water

    Same problem, only 1 year. Still under Warrenty (5 years). Neither Sears nor Fedders can honor the warranty. A post on the Internet shows Maytag (maybe only for Dehumidifiew, who know how they play this game?) files for chapter 6 bankruptcy protection. I guess I'll have to get a new one. Anyway, I think the unit has lost it's freon.

Found out about the filter on the left side of the unit. Mine was caked with dirt and would not allow air to pass. Cleaned with nozzle from vacuum and it works great now.

Either the compressor has suffered an electrical failure, or the unit has lost it's freon charge. These are generally not worth repairing. Recommend a new unit.

The unit runs but no longer removes water from the air, there is high humidity in the basement. Is it worth repairing the unit because it's 7 years old and where can I purchase another Mayta unit?


Edward, there are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder
level
in basement applications . Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older.

Hope this helped you to troubleshoot and solve the problem without having to make any repairs or replacement of the unit.

The room is 70 degrees f but the coils still ice up. What is the problem?


Most of the time, the most common reason is a dirty or clogged air intake filter. Turn the Master ON/Off Switch to OFF and unplug the unit from the wall outlet. Put some old towels under the unit and allow it to thaw completely, before removing the filter for cleaning. Also, if you can access the cooling coils, wiping them down with warm water and a mild detergent (dish washing liquid is fine) rinse and dry completely. A light coating of WD40 after they're dry helps too.

Worse case scenario is that the compressor is low on refrigerant gas and needs recharging. Or the defrost sensor has failed and needs to be replaced.

Depending on the age of the unit, will determine if it's worth repairing. If it's over 5 years old, get a new one. Less than 5 years old, it's worth considering to have it repaired. Contact Goldstar Tech Service (800) 243-0000 for an idea on the cost of repair.

Hope this helps you troubleshoot and solve the problem. Please let me know. Thanks.

Dehumidifer Runs but doesn't collect water


Depends on he conditions of the water. These units are relatively inexpensive and typically do not justify the expense of repair. I'ld donate it to an air conditioning school and buy another one.

Runs - but no water in bucket


Hello. If your dehumidifier doesn't seem to run often but the humidity in the room is high, try adjusting the humidistat control on the dehumidifier to a dryer setting. If the dehumidifier seems to run constantly, but there's little or no water in the container, there may be a problem in the refrigeration system. Try cleaning the unit. If that doesn't work, you can't repair the refrigeration system yourself, you need a qualified appliance repair technician to do that.

Mine leaks. Had leaked at other times but i took the vacuum cleaner to the front drain spout, that leaks into the removable basin. That worked in the past, but i't's not working now . The water is overflowing at the back of the catch tray and leaking out through the bottom underneath. The holes are clear, so it shouldn't be doing this. I am stumped.
