SOURCE: Doesn't want to stay on...
Most likely the fan motor has broken. Without the fan, the compressor will overheat. There is a safety device inside that automatically shuts off the compressor to keep the overheating from destroying it. Check to see if you can feel air movement in the front or back of the unit while it is running. If not, then the fan motor has definitely broke. I had this exact problem on mine.
If you take the unit apart, you will find a parts list inside the unit. It will be inside a small plastic pouch. You can order a new fan motor from Sears. The cost is $30 plus shipping.
You will have to move the condensing coil in the front out a bit in order to exchange the motors. Just be careful not to break any of the copper lines. They are copper so they will flex quite a bit without breaking. Still, use caution. If you break the lines, all the refrigerant will leak out and your unit will be useless.

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.
Hope that helps! Should you have any further questions, please feel free to post them here.

most probable cause of a dehumidifier not collecting water when it appears to run fine otherwise is a dirty heat exchanger. It is unlikely that a huge spread in the time a unit works is caused by failure of the compressor of loss of refrigerant. On the other hand, people use their units in very varied conditions of dust in the environment with expected short to long operating times before failure. Here's how to fix this problem in two steps.
Step 1: Determine if your compressor and refrigerant sealed unit is operational
Step 2: If Step one is negative, dispose of the unit - specialized equipment is required to repair or recharge a compressor. If step one is positive, then clean the heat exchanger.

SOURCE: Dehumidifier Freezing up
Your dehumidifiers are LOW on freon. Over time, small leaks will occur and the coils will freeze. Take your units to a qualified repair shop (central air, or furnace) and recharge the freon.

SOURCE: I have a frigidaire LAD704DUL 70 pint dehumidifier. Last year it worked great. This year, it has not collected any water in the bucket. The motor runs, it is on CO setting but still no water. I have c
If you have a dehumidifier that is not producing any water
then you are wondering what you need to do to get this thing to work
for you. In some cases you may be able to do something and in other
situations there may be nothing that you can do.
If you do not hear the compressor running and the unit says that the humidity in the room is higher then the setting, then you have a problem with your dehumidifier.
A few things that can cause this are:
The circuit board relay has gone bad...replacement of this board will often cost more then a new unit. This also is a very common problem with many dehumidification units.
The compressor has failed...if you hear a buzz for a few seconds, every few minutes, then you have a bad compressor or at least bad start components on the compressor. Either way it again is a costly repair.
If the compressor is running and the coils are not getting cold then you have a refrigeration system leak. Recharging or fixing these units is very difficult and is another costly venture compared to the price of a new dehumidifier.
If the compressor is running but the fan is not, this also will cause low water production and continual freezing of the coil.
If the compressor and the fan are running but the coil is totally blocked then you will get no water production. Air needs to be continually moved over the cold coil to get the water out of the air.
If nothing is running, then you may also have a control board failure. Or the humidity sensor or humidistat has gone bad which tells the machine to run. If the sensor says that the humidity is low enough then it will never run.
Also if nothing is running check the float switch or the bucket switch. Many of these switches are very touchy and if you do not have the bucket in place just exactly right it will not trip the switch to allow the unit to run. These switches often are more fragile then they should be and break easily. The good thing is that when available they are easy to replace and relatively inexpensive.
There are some parts available for a few brands, but with the prices for most of the parts that you can replace running anywhere from 40.00 - 80.00 dollars, replacement parts with labor to install them, makes a repair more then the few hundred dollar cost of many of these dehumidifiers.
As you can see there are quite a few things that can cause your dehumidifier not to work. Systematically go through the list and eliminate things to get to the bottom of the issue causing your problem and then decide if it is worth spending the money to try to fix the old unit. Only you can make that decision.
