Won't come on

cont button just means continuous run mode . the power light is lit , the full light is out . try reseating the water catch bucket a few times , most machines have a safety that wont allow the thing to operate if bucket isn't just perfect in its slot (you don't want water on your floor )

if thats where you run it at 40 i suspect it's overheating and shut off possibly broken now , one should never set a humidistat less than say 66%rh as a normal house is 70%rh and asking anything more of a home unit is just not possible if moisture is that much a problem try running two units about twenty feet apart , they will cycle more to cool down and will run longer , might even be more efficient than running one harder

if it's been in constant service for two years , has it even been cleaned ??? ,And i mean more than just the air filter , two years is a long time to have home air blowing thru this thing and im sure it's picked up a lot of common invisable house dust inside and now it's affected the operation of the unit

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

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. It's rare in a unit younger than that. But, it can happen.

I hope this has helped you troubleshoot and solve the problem. Thanks for choosing FixYa.

If you just plugged it in and started it up, you may have failed to set the humidity extraction level. Which is different from the factory settings. If you want to remove great deal of humidity, lower the setting to 35%. Keep in mind, the lower the setting the more humidity/moisture will be removed from the household air. The higher the setting less will be removed.

As far as the unit beiing warm is concerned ... Be sure to maintain at least a minimum of 12" clear air space all around the unit while in operation. Do not operate the dehumidifier in direct sun light.

Also, make sure all the packing material has been removed from the interior of the unit. This will block the airflow and cause the unit to overheat. If it does overheat, it should shutoff automatically. But, don't confuse that with normal automatic shutoff (i.e water collection bucket full, timed cycle has ended, no more humidity to remove from the air, etc.)

When all else fails, consult the owner's Manual.

Hope this helped you. Please let me know.

Hi,
Dehumidifiers freezing up can be causes by a few different problems.
Here is a tip that I wrote to help people with the freezing dehumidifier problem....

Check if the fan is running by putting your against the grill in front or back of the unit.
