I understand that you are hearing a high pitched noise coming from your Frigidaire dehumidifier, model# FDF50S, and want to know what it is. There are several possibilities that could be causing this high pitched sound. I suggest contacting either the manufacturer or your local authorized technician for further assistance. The technician will be able to diagnose your dehumidifier and determine exactly what the cause is. Hope this is helpful.
Here is a link to an Owner's Manual for a Haier 45 pint dehumidifier. Not sure if yours exactly like it or not, as you didn't mention a model number. You can download and print the manual for future reference.
mcdevito75 here, It could be the capacitor if you can replace with same size do so. The Armature or communtator in the motor could be shorting also, do the capacitor the change the motor.
It sounds like the bearings in the motor are worn out, especially as you said it quits running at times. You should be safe in just replacing the fan motor, but check the fan blade to make sure it isn't out of balance for any reason(dirty, missing a balance weight, or bent). Hope I was of assistence!
try a hard start kit it has an electronic start instead of mechanical and has a large start capacitor to give an extra punch to get it going if it is stuck i put240 volts just to the compressor for just for a sec...
I'm working on mine right now as we speak with the same problem , it runs for 3-4 minutes and then drops out and what I think I have found is the compressor comes on but the fan that blows over the condensor/evaporator assemblies never turns on ! I tore the covers of mine and put a volt meter across the orange and black wires (with the unit on high ) , on the little white plug in the metal box on a pc board , that all the wires go into and with the comressor off just before it starts on power up I have 122vac (volts ac) and then the compressor kicks in and it drops to about 107 vac but no fan action so I'm getting on line to order a motor assembly Kenmore # 4681A20040K ! I just happened across this site so I hope It works for me and helps you !
That capacitor is a run cap for the compressor. Your problem sounds like a faulty connection in the circuit which supplies power to the solid state electronics. The electronics will have a 115 VAC supply from the rest of the machine's circuitry, most likely running to a small transformer. Check for 115VAC when you attempt to start the machine. Trace the circuit until you find the point where the power disappears when the start is pushed. If this does not reveal the problem, replace the board that has the transformer on it. There is a faulty connection somewhere which is opening when power is drawn. It is also possible that the compressor is locked & drawing enough power to disable the rest of the machine. Try it with the compressor disconnected, before replacing anything.

check for a dry axle shaft bearing
