From a cold start, the dehumidifier starts and the fan kicks on. But after running for 2-3 minutes it shuts off. If you remove bucket and reinstall the fan will come on for a short period and shut off...


Wayne, 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%. If you have an analog unit
(no LED screen) set the humidity extraction knob on maximum.

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.

Hope this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

Put empty bucket in,it runs for minute,then shuts off. need a switch that won't shut off. Where could I find one my zip code is 44451.


The switch may not be the problem. However, a dirty or clogged air intake filter or the humidity extraction level set to high could be.

Turn the unit OFF & unplug it.
Remove and clean the air intake filter thoroughly. Be sure the filter is completely dry, before reinstalling. Never operate the unit without the filter in place.

After the filter is dry, reinstall it, plug the unit and turn it ON. Lower the humidity extraction level to 35%. If you have an analog unit (No LED screen) set the humidity extraction knob on Maximum.

And finally, be sure that the water collection bucket is installed properly and is not vibrating loose when the unit runs. It should fit squarely into it's holder, making contact with the bucket safety removal switch on the back wall of the bucket holder. When installed properly, it should not tilt down at the bottom of the bucket.

All of the above should solve the problem and you won't need to purchase a new switch. But, in the unlikely event, that you will have to. You will need to furnish the Brand Name of the unit and the Correct Model Number. As, they are not all the same.

Hope this helped you and thanks for choosing FixYa.

Gayle, your unit has some age on it, but it may still be salvageable .

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%. Or set to Maximum if yours
is a manually controlled unit.

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.

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. As far as repairs are concerned: The unit is 14 - 16 years old and the cost to repair, may be as much (or close to it) as purchasing a new unit. If you decide to purchase a new unit, be sure it's a "Low Temperature" model, as yours is being used primarily in a basement application.
