Fan and Compressor turns on when plugged in, but compressor kicks off and fan runs for a few minutes until unit shuts off. No power source problem and compressor is not frozen.
I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad.
Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.

So I just had this happen with my Frigidaire fad704dwd dehumidifier. I went to basement and heard it running and sounded off. The compressor was running fan was off which is bad and humidity said 30. I then pushed the off button and it stayed running. I was able to fix it. To make long story short it was a bad ground. I took the plastic back, sides, and front off. There was a green ground (main ground) and Green/yellow ground (fan ground) on the front coil with a bunch of rust. Removed the grounds connected them both together and cleaned the surface area and used a new stainless screw nut and screw to remount the wires to evaporator coil. Everything started working fine after that and I put it back together. Good Luck

Fan run's for a short time then turs off.
COMPRESSOR SHUTS OFF AND FAN SHUTS OFF
A SHORT TIME LATER.
The dehumidifier fan runs for approximately a minute,then shuts off.jumped out sensor located on front of coil, the compressor comes on then coil begins to freeze and shuts down within a few minutes.could this sensor be bad and if so are parts available.
Part no.LHD30
serial no.501tagh13151
