Model BHD-301-D Will run from 1 min to 4min then shut off. I've tried all setting from 3 to top does same thing. I have a wet basement so it should stay on all the time. If I unplug it and then plug it back in it will run for a short time again? Its like new and not used much till now but will not work.

There are 5 basic, yet solvable reasons 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%. If you have a mechanical unit,
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 - 65 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 helps you to trouble shoot and solve the problem. Thanks for choosing FixYa.
